Will future asteroids trigger massive extinctions—or be mined for precious minerals? Will asteroids turn out to be our economic salvation-or instruments of destruction? - The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look up at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars’ worth of elements like iron, nickel, and platinum. NASA is planning an ambitious mission to return samples from a potentially hazardous asteroid, and would-be asteroid miners are dreaming up their own program to scout for potentially profitable asteroids. Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. The current known asteroid count is: 1,266,766 Analysis of data obtained by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft's kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology. “All of us have a responsibility to protect our home planet. After all, it’s the only one we have,” said NASA Administrator Bill Nelson. “This mission shows that NASA is trying to be ready for whatever the universe throws at us. NASA has proven we are serious as a defender of the planet. This is a watershed moment for planetary defense and all of humanity, demonstrating commitment from NASA's exceptional team and partners from around the world.” Prior to DART’s impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid, Didymos. Since DART’s intentional collision with Dimorphos on Sept. 26, astronomers have been using telescopes on Earth to measure how much that time has changed. Now, the investigation team has confirmed the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes. Before its encounter, NASA had defined a minimum successful orbit period change of Dimorphos as change of 73 seconds or more. This early data show DART surpassed this minimum benchmark by more than 25 times. “This result is one important step toward understanding the full effect of DART’s impact with its target asteroid” said Lori Glaze, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “As new data come in each day, astronomers will be able to better assess whether, and how, a mission like DART could be used in the future to help protect Earth from a collision with an asteroid if we ever discover one headed our way.” #sciencefacts #interestingfacts #future

The history of explosives and propellants, also known generally as ‘energetic materials’, begins with the material known as gunpowder or black powder, whether the intended use was for civil applications such as rock blasting, military uses in demolition, shell filling (bursting charges) and construction projects, or military and civilian propellant charges for shotguns, pistols, rifles, or artillery. The individual inventor of black powder will undoubtedly forever remain unknown, but numerous writers such as Drinker (1878), Munroe (1888), Marshall (1915), and Davis (1941, 1943), have described what is known about its development and evolution: therefore, there will be no such discussion here. Suffice to say that until the discovery of nitrated explosive compounds such as nitrocellulose by Schönbein and Böttger (independently of one another) and nitroglycerin by Sobrero (all occurring in 1846), the only explosive available for any purpose was black powder. The instantaneous release of energy from a relatively small volume of material can be viewed as an explosive event. This is achieved by changes in the chemical composition of the solid, liquid or gas, and the release of chemical energy. Depending on initiation conditions, charge geometry and chemical composition, this reaction can accelerate until a steady value (detonation) has been achieved, or decelerate (deflagration) and eventually die out. The distinction between true detonation and deflagration is not crucial at this stage, as both processes can lead to release of very large amounts of energy in a small fraction of a second. Most incidents involving dust or vapour cloud explosions (flour, sawdust, gasoline vapours, natural gas, etc.) involve only rapid combustion and not detonation. Most commercial explosives such as ammonium nitrate (AN)-fuel oil mixtures exhibit non-ideal behaviour, in that their sensitivity and severity of explosion falls off rapidly with decreasing diameter and lack of confinement. In this discussion, confined to condensed phase explosions, the words ‘detonation’ and ‘explosion’ are used synonymously and no distinction is made between commercial and military explosives. IN both Great Britain and the United States the explosives industry has formed one of the most important nuclei round which the powerful chemical combinations now existing in these two countries have developed. A history of the British explosives industry, edited by E. A. B. Hodgetts, was published in 1909, under the direction of the Explosives Section of the seventh International Congress of Applied Chemistry; the present publication deals with the history of the explosives industry in the United States and Canada, and to some extent in Mexico and South America. It has been written and published under the auspices of the Institute of Makers of Explosives, and the material has been collected from pioneer workers who are still living, from the records and archives of large powder companies, and “for the earlier history, more particularly the origins of the black powder business, data have been found in colonial records and local histories of towns, counties, and states.” #science #technology #boom

How deep is the ocean? - The average depth of the ocean is about 3,688 meters (12,100 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep. It is named after the HMS Challenger, whose crew first sounded the depths of the trench in 1875. This film tells the story of the moving sea floor, from its formation at the mid-ocean ridges, to its demise in the deep-sea trenches thousands of miles away. We compress a journey that takes 200 million years into an incident packed 50 minutes. We start with the mystery of Hawaii, an island that is sinking, and moving. But why? The first clue came in the Second World War, when a US landing craft commander deduced that the sea floor was moving. To discover why, we dive to the strange underwater world of the ocean ridges where volcanic rock spewing out of the earth creates new sea floor. This is the realm of black smokers, and white chimneys, hydrothermal vents that create their own ecosystem. From here we descend to the flat landscape of the abyssal plain, where the only features are decaying whale carcasses. Even here, the evidence shows that the seabed is moving. Finally, we see strange mud volcanoes thrown up as the sea floor descends into the deepest part of the ocean, and melts back into the mantle of the earth. #science #adventure #explore

One of the best self-defense instructors in the world demonstrates how to survive. Jiu-jitsu instructor Rener Gracie shares some tips on how to fend off an attacker on 'Unfiltered with Dan Bongino.' after video goes viral of woman being attacked in the Florida gym. Nashali Alma, 24, was exercising in the gym at the Inwood Park Apartment Complex in Tampa when Xavier Thomas-Jones attacked her Jan. 22, the Hillsborough County Sheriff’s Office charged. Security footage posted on social media by the sheriff’s office shows Alma letting Thomas-Jones into the facility before continuing her workout. Thomas-Jones, 25, is then seen trying to grab Alma’s waist and taking her down to the ground— Alma eventually was able to get back on her feet and run to a nearby apartment, where she called 911.Thomas-Jones fled — and tried to enter another woman’s apartment in the complex. He was apprehended by deputies less than 24 hours later. #jiujitsu #selfdefense #martialarts

Paleontologist Jack Horner questions the assumption that Tyrannosaurus Rex was a predator. He thinks there is a reasonable chance it was a scavenger that had little ability to hunt or even run. He's out in the field looking for evidence to try to settle the debate. Horner with his digging team, travel to Hell Creek Formation in search for dinosaur fossils, while also following Horner as he presents his view of the theropod dinosaur Tyrannosaurus rex as a scavenger rather than a predator, as it is often portrayed in popular culture. Why a New T. Rex Study Is Riling Up the Paleontology World - Established scientists are casting serious doubts on new research suggesting that the infamous, ferocious dinosaur is actually three different species. The Tyrannosaurus rex is perhaps the most famous and recognizable dinosaur, fascinating scientists and the public alike. With its enormous body and small arms, the “King of the Tyrant Lizards” was one of the largest land-dwelling predators. Now, in a controversial new study published in Evolutionary Biology, researchers are proposing that the T. rex was actually three different species: T. rex, T. regina and T. imperator. “This paper is likely to rock the paleo community, and the public that is so used to good old T. rex,” Gregory Paul, an independent paleontologist, paleoartist and author on the study, tells the New York Times’ Asher Elbein. The researchers examined 37 specimens, looking at variations in femur sizes and dentistry, as well as the layers in which the dinosaurs were found. They posit that specimens found in lower layers are the species T. imperator, stocky-boned specimens are the T. rex, while the smaller boned specimens are a species called T. regina, or “tyrant lizard queen,” writes the Guardian’s Nicola Davis. But some paleontologists who have been in the field for years aren’t convinced by the new paper. “It’s just shades of gray and shapes in clouds — there’s no validity here at all,” Thomas Carr, a paleontologist at Carthage College in Kenosha, Wisconsin, tells National Geographic’s Michael Greshko. Carr previously studied variations in 1,850 different features in T. rex specimens and found no evidence that the species should be split up. He tells Popular Science’s Shi En Kim that the new research shows only subtle differences that could be attributed to variations among individuals. “The features that identify species are utterly unique, smack-in-the-face-with-a-frying-pan obvious,” he tells the publication. Moreover, the authors were unable to assign a species to several of the skulls, despite them being in excellent condition, he says. Another paleontologist, Steve Brusatte from the University of Edinburgh, tells the Guardian that he too disagrees with the paper’s findings. “I understand the temptation to divide T. rex into different species, because there is some variation in the fossil bones that we have,” he says to the Guardian. “But ultimately, to me, this variation is very minor and not indicative of meaningful biological separation of distinct species that can be defined based on clear, explicit, consistent differences.” Part of this debate stems from the fact that scientists don’t universally agree upon what counts as a species, per the Times, and dinosaur taxonomy is subjective. Currently, the T. rex is the only species in the genus Tyrannosaurus, but the study’s authors say this is only because of a lack of research on enough specimens. “For over a century, the species T. rex potentially being a de facto taxonomic waste basket was to a fair extent a consequence of available sample size, the number of reasonably complete Tyrannosaurus skeletons being much too small to sufficiently examine the issue,” the authors write. “However, that situation of taxonomic stagnation due to specimen deprivation has dramatically improved since the late 1900s. An in-depth examination is now possible.” Paul tells Reuters’ Will Dunham that he knows the study will spark controversy, and the dino’s iconic status will only amplify the debate. “I’m aware that there could be a lot of people who aren’t going to be happy about this,” he tells the Times. “And my response to them is: Publish a refutation.” #history #evolution #dinosaur

Medieval castles were built from the 11th century CE for rulers to demonstrate their wealth and power to the local populace, to provide a place of defense and safe retreat in the case of attack, defend strategically important sites like river crossings, passages through hills, mountains and frontiers, and as a place of residence. Whether a permanent home for a local lord or a temporary one for a ruler embarking on a tour of their kingdom, castles were converted from wood into stone and became ever more impressive structures with more and more defensive features such as round towers and fortified gates. Evolution A good location for a castle was on a natural rise, near a cliff, on the bend of a river, or where older fortifications such as Roman walls could be usefully reused. Castles needed their own water and food supplies and usually a permanent defensive force, additional factors to be considered when choosing a location. Castles were an expensive undertaking which could take years to finish. A master mason, who was, in effect also the architect, led a team of hundreds of skilled workers ranging from carpenters to blacksmiths and dyke specialists to common labourers. The transportation of materials was the highest cost of all so the proximity of a local quarry was a big plus. THE TOWER KEEP BECAME A STAPLE FEATURE OF MEDIEVAL CASTLES, ALTHOUGH THEY WERE CALLED A DONJON PRIOR TO THE 16TH CENTURY CE. The earliest form of castle was a simple wooden palisade, perhaps with earthworks, surrounding a camp, sometimes with a permanent wooden tower in the centre. This then evolved into the motte and bailey castle - a wall encircling an open space or courtyard (bailey) and a natural or artificial hill (motte) which had a wooden tower built on top of it. These were especially popular with the Normans from the 11th century CE. In the next stage of development, an outer wall was built of stone on top of the motte and then known as a shell keep. Finally, in the 12th century CE, the outer wall and main central tower also came to be built of stone, but not usually on the motte itself as that was not stable enough to use as a foundation for such a heavy structure. Indeed, entirely new locations might be preferred or required, and the foundation of choice was bedrock which prevented any undermining by an attacking force. The keep became a staple feature of castles, although they were called a donjon (from the French word meaning 'lord') prior to the 16th century CE. Usually with three or more stories (tower keeps); some were lower and are called hall keeps. The keep was the heart of the medieval castle and the last point of refuge in case of attack or siege. Before they got to the keep, though, attackers had to negotiate a long list of defensive features. Features The typical features of a medieval castle were: Moat - a perimeter ditch with or without water Barbican - a fortification to protect a gate Curtain Walls & Towers - the perimeter defensive wall Fortified Gatehouse - the main castle entrance Keep (aka Donjon or Great Tower) - the largest tower and best stronghold of the castle Bailey or Inner Ward (courtyard) - the area within a curtain wall. Moat An artificial ditch or moat was dug to surround the entire castle complex and could be filled with water permanently or temporarily during attack in some cases. As creating a moat was a huge undertaking, the presence of natural rises and depressions were important factors in choosing where to build the castle in the first place. The earth or stone excavated while preparing the moat could be used to build up the mound on which the castle would be subsequently built. The moat was made deep enough to impede attackers on horse, foot or equipped with siege towers. The sides were steep and could be riveted with wooden stakes to increase their slipperiness. Stakes might also be placed in the bottom to further impede crossing. If filled with water, only a half-metre depth was required to obstruct the enemy and make them more vulnerable to missiles fired from the walls above. Barbican The barbican was a defensive fortification built to protect potential weak spots like a gate. Typically consisting of a short stretch of fortified wall, perhaps forming an echelon form, it allowed the defenders to ward off a direct attack on the wall or gate proper. The barbican could be protected by covering fire from the towers behind it and was sometimes surrounded by its own wall and/or ditch (with accompanying drawbridge or swing bridge) when it was known as a courtyard barbican. A second type was the passageway barbican which was similar to a fortified corridor leading from a gateway outwards. By the mid-13th century CE, barbicans were set more distant from the outer wall, at an angle from a gate and incorporating a 90-degree turn within them (between the entrance and exit bridges) to further impede access to the castle proper. #history #architecture #interestingfacts

World Most Feared Super Submarine in U.S, Navy - The Virginia Class attack submarine is the U.S. Navy’s newest undersea warfare platform and incorporates the latest in stealth, intelligence gathering and weapons systems technology. Attack submarines are designed to seek and destroy enemy submarines and surface ships; project power ashore with Tomahawk cruise missiles and Special Operation Forces; carry out Intelligence, Surveillance, and Reconnaissance (ISR) missions; support battle group operations; and engage in mine warfare. The Virginia class wa not the first new design to come into service after the Cold War. The Seawolf class was originally intended to succeed the Los Angeles class, but production was canceled after only three submarines were produced. This restriction occurred due to budgeting restraints at the end of the Cold War, and the final submarine was manufactured in 1995. At a cost of $3 billion per unit, the Seawolf class was the most expensive SSN submarine. The Virginia class was put into production in full swing due to being smaller and carrying more manageable costs than the Seawolf. The Navy is now building the next-generation attack submarine, the Virginia (SSN 774) class. The Virginia class has several innovations that significantly enhance its warfighting capabilities with an emphasis on littoral operations. Virginia class SSNs have a fly-by-wire ship control system that provides improved shallow-water ship handling. The class has special features to support special operation forces including a reconfigurable torpedo room which can accommodate a large number of special operation forces and all their equipment for prolonged deployments and future off-board payloads. The class also has a large lock-in/lock-out chamber for divers. In Virginia-class SSNs, traditional periscopes have been supplanted by two photonics masts that host visible and infrared digital cameras atop telescoping arms. With the removal of the barrel periscopes, the ship’s control room has been moved down one deck and away from the hull’s curvature, affording it more room and an improved layout that provides the commanding officer with enhanced situational awareness. Additionally, through the extensive use of modular construction, open architecture, and commercial off-the-shelf components, the Virginia class is designed to remain state of the practice for its entire operational life through the rapid introduction of new systems and payloads. As part of the Virginia-class’ third, or Block III, contract, the Navy redesigned approximately 20 percent of the ship to reduce their acquisition costs. Most of the changes are found in the bow where the traditional, air-backed sonar sphere has been replaced with a water-backed Large Aperture Bow (LAB) array which reduces acquisition and life-cycle costs while providing enhanced passive detection capabilities. The new bow also replaces the 12 individual Vertical Launch System (VLS) tubes with two 87-inch Virginia Payload Tubes (VPTs), each capable of launching six Tomahawk cruise missiles. The VPTs simplify construction, reduce acquisition costs, and provide for more payload flexibility than the smaller VLS tubes due to their added volume. United States Navy (USN).

Just a few decades ago, the only planets we were sure that existed were those orbiting our sun, making up our solar system. Astronomers thought it was very likely that there were also planets orbiting other stars, but these were almost impossible to detect because they were so small, relatively speaking, and so far away. But since the first planet outside our solar system (or exoplanet) was discovered in 1992, the number of known exoplanets has exploded into an exciting and active field of research. The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes. The planetary odometer turned on March 21, with the latest batch of 65 exoplanets – planets outside our immediate solar family – added to the NASA Exoplanet Archive. The archive records exoplanet discoveries that appear in peer-reviewed, scientific papers, and that have been confirmed using multiple detection methods or by analytical techniques. The 5,000-plus planets found so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and “hot Jupiters” in scorchingly close orbits around their stars. There are “super-Earths,” which are possible rocky worlds bigger than our own, and “mini-Neptunes,” smaller versions of our system’s Neptune. Add to the mix planets orbiting two stars at once and planets stubbornly orbiting the collapsed remnants of dead stars. “It’s not just a number,” said Jessie Christiansen, science lead for the archive and a research scientist with the NASA Exoplanet Science Institute at Caltech in Pasadena. “Each one of them is a new world, a brand-new planet. I get excited about every one because we don’t know anything about them.” We do know this: Our galaxy likely holds hundreds of billions of such planets. The steady drumbeat of discovery began in 1992 with strange new worlds orbiting an even stranger star. It was a type of neutron star known as a pulsar, a rapidly spinning stellar corpse that pulses with millisecond bursts of searing radiation. Measuring slight changes in the timing of the pulses allowed scientists to reveal planets in orbit around the pulsar. Finding just three planets around this spinning star essentially opened the floodgates, said Alexander Wolszczan, the lead author on the paper that, 30 years ago, unveiled the first planets to be confirmed outside our solar system. “If you can find planets around a neutron star, planets have to be basically everywhere,” Wolszczan said. “The planet production process has to be very robust.” Wolszczan, who still searches for exoplanets as a professor at Penn State, says we’re opening an era of discovery that will go beyond simply adding new planets to the list. The Transiting Exoplanet Survey Satellite (TESS), launched in 2018, continues to make new exoplanet discoveries. But soon powerful next-generation telescopes and their highly sensitive instruments, starting with the recently launched James Webb Space Telescope, will capture light from the atmospheres of exoplanets, reading which gases are present to potentially identify tell-tale signs of habitable conditions. The Nancy Grace Roman Space Telescope, expected to launch in 2027, will make new exoplanet discoveries using a variety of methods. The ESA (European Space Agency) mission ARIEL, launching in 2029, will observe exoplanet atmospheres; a piece of NASA technology aboard, called CASE, will help zero in on exoplanet clouds and hazes. “To my thinking, it is inevitable that we’ll find some kind of life somewhere – most likely of some primitive kind,” Wolszczan said. The close connection between the chemistry of life on Earth and chemistry found throughout the universe, as well as the detection of widespread organic molecules, suggests detection of life itself is only a matter of time, he added.

https://www.facebook.com/hiddencolumbia/videos /10150197461001481/ ....William Ellison was one of the wealthiest men in the South as well as being a black, former slave. He owned cotton gins, plantations, and 68 slaves. And from accounts of the time, he wasn't very nice...At the peak of slavery in the United States, large numbers of free Negroes owned black slaves; in fact, in numbers disproportionate to their representation in society at large. In 1860 only a small minority of whites owned slaves. According to the U.S. census report for that last year before the Civil War, there were nearly 27 million whites in the country. Some 8 million of them lived in the slaveholding states. The census also determined that there were fewer than 385,000 individuals who owned slaves. Even if all slaveholders had been white, that would amount to only 1.4 percent of whites in the country (or 4.8 % of southern whites owning one or more slaves, however, around 30% for free blacks owned slaves). In the rare instances when the ownership of slaves by free Negroes is acknowledged in the history books, justiJcation centers on the claim that black slave masters were simply individuals who purchased the freedom of a spouse or child from a white slaveholder and had been unable to legally manumit them. Although this did indeed happen at times, it is a misrepresentation of the majority of instances, one which is debunked by records of the period on blacks who owned slaves. These include individuals such as Justus Angel and Mistress L. Horry, of Colleton District, South Carolina, who each owned 84 slaves in 1830. In fact, in 1830 a fourth of the free Negro slave masters in South Carolina owned 10 or more slaves; eight owning 30 or more. #history #facts #strangerthings

What Might Be Speeding Up the Universe’s Expansion? - Physicists have proposed extra cosmic ingredients that could explain the faster-than-expected expansion of space. The discrepancy between how fast the universe seems to be expanding and how fast we expect it to expand is one of cosmology’s most stubbornly persistent anomalies. Cosmologists base their expectation of the expansion rate — a rate known as the Hubble constant — on measurements of radiation emitted shortly after the Big Bang. This radiation reveals the precise ingredients of the early universe. Cosmologists plug the ingredients into their model of cosmic evolution and run the model forward to see how quickly space should be expanding today. Yet the prediction falls short: When cosmologists observe astronomical objects such as pulsating stars and exploding supernovas, they see a universe that’s expanding faster, with a larger Hubble constant. The discrepancy, known as the Hubble tension, has persisted even as all the measurements have grown more precise. Some astrophysicists continue to debate whether the tension might be nothing more than a measurement error. But if the discrepancy is real, it means something is missing from cosmologists’ model of the universe. Recently, theorists have been busy imagining new cosmic ingredients that, when added to the standard model, would rev up the universe’s expected expansion rate, making it match observations. “Discovering anomalies is the fundamental way that science makes progress,” said Avi Loeb, a cosmologist at Harvard University and one of dozens of researchers who have proposed solutions to the Hubble tension. These are some of the top ideas for what could be speeding up cosmic expansion. Decaying Dark Matter The standard model of cosmology incorporates all the familiar forms of matter and radiation and their interactions. It also includes the invisible substances known as dark energy and dark matter, which together make up some 96% of the cosmos. Because so little is known about these dark ingredients, they are perhaps the obvious place to begin tampering with the standard model. “That’s what you have at your disposal to change the expansion rate of the universe,” Loeb said. The standard model assumes that dark matter consists of slow-moving particles that don’t interact with light. But what if we also assume that dark matter is not made of just a single substance? Since many different kinds of visible particles exist — quarks, electrons and so on — there might be multiple dark particles as well. In a paper published last summer in Physical Review D, Loeb and two collaborators considered a form of dark matter that decays into a lighter particle and a massless particle known as a dark photon. As more and more dark matter decayed over time, they reasoned, its gravitational pull would have lessened, and thus the expansion of the universe would have sped up, relieving the Hubble tension. But making small changes like this to the standard cosmological model can have unwanted knock-on effects. “It’s very easy to come up with all kinds of slight modifications,” said Marc Kamionkowski, a theoretical physicist at Johns Hopkins University — but it’s hard to do so, he said, without ruining the model’s perfect fit with a wealth of other astronomical observations. By varying the decay rate and the amount of dark matter that is lost in each decay, Loeb and colleagues selected a model of decaying dark matter that they say still agrees with other astronomical observations. “If you add this ingredient to the standard model of cosmology, everything holds together,” Loeb said. Yet he remains dissatisfied with the decaying dark matter idea, in part because it introduces two new uncertain quantities into the equations. “In this case, you add two free parameters in order to resolve one discrepancy — and I’m uneasy about that,” he said, comparing decaying dark matter to the epicycles in Ptolemy’s Earth-centric model of the universe. “I would rather have two discrepancies explained by one parameter.” Modified Gravity In the standard model of cosmology, all known forms of matter and radiation, plus dark matter and dark energy, are fed into Albert Einstein’s theory of gravity, and Einstein’s equations indicate how space expands as a result. This means that, besides changing or adding cosmic ingredients to the model, there’s another way physicists can reconcile it with the observed cosmic expansion rate: “You can imagine that Einstein’s equations are not correct,” Loeb said. William Barker, a doctoral student at the University of Cambridge, was searching for a theory of “modified gravity” last summer when he stumbled across a way to resolve the Hubble tension. Barker found a modified-gravity model that was “capable of behaving as if there were extra radiation in the early universe,” he said; the radiation pressure would have increased the cosmic expansion rate. #space #strange #discovery

The moon holds a significant relationship with the Earth: if there were no moon, our daily lives as humans would significantly change. The first and most obvious change would be during the nighttime. Nights would be unbelievably darker, as the moon provides light to the Earth during the night hours by reflecting light from the sun. Scientists suggest that without human-made lighting, we would not be able to see the hands in front of our face without the moon during the nighttime. However, not only would nights be darker, but our days would change as well. Just as the Earth exerts a gravitational pull, the moon also exerts a gravitational pull on the Earth. The moon pulls on the Earth and slows down the Earth’s rotation. The moon’s pull creates a bulge near the Earth’s equator, which means there is a lower level of water at the poles. The Moon’s gravity causes the oceans on our planet to rise and fall. As the water moves, there is slight friction between the moving water and the spinning Earth. This friction causes the Earth’s rotation to slow slightly. If there was no moon, then the water might spread across the planet equally and reduce the amount of friction. This means that the earth would not slow, which then means that the hours of our days would change. Suddenly, without the moon, our days would last between 6 and 12 hours, rather than the 24 hours we experience now. If our days became this short, then we would have significantly more days in our calendar year. Instead of 365 days in a year, we would have over a thousand. Since the moon affects the altitude and movement of Earth’s water, our ocean tides would shrink. High tide occurs where the ocean bulges toward the moon, or where the moon pulls the ocean towards it. On the opposite side of our planet, the ocean bulges away from the moon, creating another high tide. The low tides occur on either side of the bulges. Remember that the Earth is rotating, so high tide becomes low tide as the Earth turns. Scientists suggest that without the moon, tides would be 1/3 of the size they are now. High tides would be much smaller than they are now, and low tides would be even lower. This is because the sun would be influencing the tides, not the moon; however, the sun has a weaker pull, which would decrease the tides. The change in the Earth’s rotational speed and a change in the Earth’s tilt would also affect the Earth’s weather patterns. If the moon slows down the Earth’s rotation, then the moon also affects the wind and wind speeds on our planet. Without the moon, we would see an increase in wind speeds. Winds could become much faster and much stronger without the moon. Additionally, we might see a change entirely in seasons. The moon affects the angle of the Earth’s tilt. Currently, the Earth sits at a 23.5-degree tilt. This means our planet leans slightly to one side as it sits in space. The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change. Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter. #lunar #orbit #earth
