NASA Simulation’s Plunge Into a Black Hole: Explained
NASA Simulation’s Plunge Into a Black Hole: Explained
This new, immersive visualization produced on a NASA supercomputer represents a scenario where a camera — a stand-in for a daring astronaut — enters the event horizon, sealing its fate.
Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation.
The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way galaxy. To simplify the complex calculations, the black hole is not rotating.
A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[3][4] The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity.[5] In many ways, a black hole acts like an ideal black body, as it reflects no light. Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

Alligator Chases Fisherman After He Catches Fish
Alligator Chases Fisherman after he catches fish
An alligator, or colloquially gator, is a large reptile in the genus Alligator of the family Alligatoridae of the order Crocodilia. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). Additionally, several extinct species of alligator are known from fossil remains. Alligators first appeared during the late Eocene epoch about 37 million years ago.
Species
†Alligator hailensis
†Alligator mcgrewi
†Alligator mefferdi
Alligator mississippiensis
†Alligator munensis
†Alligator olseni
†Alligator prenasalis
Alligator sinensis
†Alligator thomsoni
The name "alligator" is likely an anglicized form of el lagarto, the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator.Early English spellings of the name included allagarta and alagarto

A swarm of up to 20,000 bees can follow a car if their queen gets inside in the vehicle
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila.[1] There are over 20,000 known species of bees in seven recognized biological families.[2][3][4] Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary

How a Cockroach can survive without a head
How Cockroach can survive without head ?
Cockroaches are insects belonging to the order Blattodea (Blattaria). About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known pests
Most species of cockroach are about the size of a thumbnail, but several species are notably larger. The world's heaviest cockroach is the Australian giant burrowing cockroach Macropanesthia rhinoceros, which can reach 8 centimetres (3 in) in length and weigh up to 35 grams (1.2 oz). Comparable in size is the Central American giant cockroach Blaberus giganteus. The longest cockroach species is Megaloblatta longipennis, which can reach 97 mm (3+7⁄8 in) in length and 45 mm (1+3⁄4 in) across. A Central and South American species, Megaloblatta blaberoides, has the largest wingspan of up to 185 mm (7+1⁄4 in). At the other end of the size scale, Attaphila cockroaches that live with leaf-cutter ants include some of the world's smallest species, growing to about 3.5 mm in length.

Worst ceremonial first pitch ever
Worst ceremonial first pitch ever
The ceremonial first pitch is a longstanding ritual of baseball in which a guest of honor throws a ball to mark the end of pregame festivities and the start of the game. Originally, the guest threw a ball from their seat in the grandstand to the pitcher or catcher of the home team, but the ritual changed after United States President Ronald Reagan threw the first pitch on the field at an unscheduled appearance at a Baltimore Orioles game. Now, the guest stands on or in front of the pitcher's mound and throws towards home plate. The ceremonial thrower sometimes stands on the mound (as a pitcher would). The recipient of the pitch is usually a player from the home team.
The practice of having ceremonial first pitches dates back to at least 1890, when throwers were often a mayor, governor, or other locally notable individual. Ohio Governor (and future U.S. president) William McKinley, for example, "threw the ball into the diamond" before an opening day game between Toledo and Columbus in 1892. Former Japanese Prime Minister Ōkuma Shigenobu threw out the ceremonial first pitch at the first game of an American All-Star team's tour of Japan in 1908, making him possibly the first person who had served as a national head of government to throw out a first pitch

Jack Dorsey showing off Twitter back in 2006
Jack Dorsey showing off Twitter back in 2006
Jack Know Dorsey (born November 19, 1976) is an American Internet entrepreneur, philanthropist, and programmer, who is a co-founder and former permanent CEO of Twitter, Inc. from 2015 until 2021, as well as co-founder, principal executive officer and chairperson[4] of Block, Inc., which is the developer of the Square financial services platform. As of October 2023, Forbes estimated his net worth to be $3.1 billion.
The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service for Odeo employees. The full version was introduced publicly on July 15, 2006. In October 2006, Biz Stone, Evan Williams, Dorsey, and other members of Odeo formed Obvious Corporation and acquired Odeo, together with its assets—including Odeo.com and Twitter.com—from the investors and shareholders.Williams fired Glass, who was silent about his part in Twitter's startup until 2011. Twitter spun off into its own company in April 2007.Williams provided insight into the ambiguity that defined this early period in a 2013 interview

Audio coming from inside the space capsule during the Apollo 1 disaster
Apollo 1, initially designated AS-204, was planned to be the first crewed mission of the Apollo program,[1] the American undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module. The mission never flew; a cabin fire during a launch rehearsal test at Cape Kennedy Air Force Station Launch Complex 34 on January 27 killed all three crew members—Command Pilot Gus Grissom, Senior Pilot Ed White, and Pilot Roger B. Chaffee—and destroyed the command module (CM). The name Apollo 1, chosen by the crew, was made official by NASA in their honor after the fire.

The Human Brain and its Networks
The Human Brain and its networks
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head
The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres. Each hemisphere has an inner core composed of white matter, and an outer surface – the cerebral cortex – composed of grey matter. The cortex has an outer layer, the neocortex, and an inner allocortex. The neocortex is made up of six neuronal layers, while the allocortex has three or four. Each hemisphere is divided into four lobes – the frontal, temporal, parietal, and occipital lobes.

Pigeon Dances to Street Music
Pigeon Dances to Street Music
The domestic pigeon (Columba livia domestica or Columba livia forma domestica) is a pigeon subspecies that was derived from the rock dove or rock pigeon. The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago, as do Egyptian hieroglyphics. Pigeons were most likely domesticated in the Mediterranean at least 3000-5000 years ago, and may have been domesticated earlier as a food source.Research suggests that domestication of pigeons occurred as early as 10,000 years ago
The bird genus Columba comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove (C. livia) has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon, some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon (C. palumbus).
pigeon, any of several hundred species of birds constituting the family Columbidae (order Columbiformes). Smaller forms are usually called doves, larger forms pigeons. An exception is the white domestic pigeon, the symbol known as the “dove of peace.

Invisible methanol fire at the 1981 Indianapolis 500
Invisible methanol fire at the 1981 Indianapolis 500
Methanol, also known as wood alcohol or methyl alcohol, is a colorless liquid with a faintly sweet alcohol odor. The chemical is fully soluble in water, and is readily biodegradable in both water and soil. Vapors of methanol are slightly heavier than air, and may travel some distance to a source of ignition and flash back. Accumulations of vapors in confined spaces may explode if ignited, and containers filled with methanol may rupture violently if exposed to fire or excessive heat for a prolonged duration. Direct exposure to methanol should be avoided as methanol can be harmful if swallowed, absorbed through the skin, or inhaled. Ingestion of as little as one to four ounces can cause irreversible injury to the nervous system, blindness or death. When properly contained and handled, methanol can be a safe and effective product for a wide range of applications.
FIRE SAFETY
The U.S. Department of Transportation regulates
methanol as a Class 3 Flammable Liquid, with a subsidiary
risk as a Class 6.1 Toxic Material. Solutions of methanol
containing up to 74% water are classified as flammable.
Compared with gasoline, methanol spills are harder to
ignite, burn at a slower rate, and with less heat intensity.
Methanol vapors must be four times more concentrated
in air than gasoline vapor for ignition to occur. Each
year, about 16,000 Americans are exposed to post-crash
fires in cars and other light-duty vehicles, resulting in hundreds of fatalities. According to the U.S. Environmental Protection Agency a switch to methanol fuel would reduce the number of automotive fuel related fires by 90% compared with gasoline, saving hundreds of lives each year.
Methanol flames are almost invisible in bright sunlight conditions, but they may be detected by the heat generated or the burning of other materials. Large amounts of water will remove heat and can be effective in diluting methanol to the point where most fires can be readily extinguished. To prevent fires keep open flames, sparks and oxidants away from methanol. For over three decades, methanol has been the fuel of choice for Indianapolis-type racecars in part because of its superior fire safety characteristics.
The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly called the Indy 500, is an annual automobile race held at Indianapolis Motor Speedway (IMS) in Speedway, Indiana, United States, an enclave suburb of Indianapolis. The event is traditionally held over Memorial Day weekend, usually the last weekend of May. It is contested as part of the IndyCar Series, the top level of American open-wheel car racing, a formula colloquially known as "Indy car racing". The track itself is nicknamed the "Brickyard", as the racing surface was paved in brick in the fall of 1909. One yard of brick remains exposed at the start/finish line. The event, billed as The Greatest Spectacle in Racing,[3] is considered part of the Triple Crown of Motorsport along with the 24 Hours of Le Mans and the Monaco Grand Prix, with which it typically shares a date.

Fire at an aluminum plant destroys the entire shop in a matter of seconds
Fire at an aluminum plant destroys the entire shop in a matter of seconds
Security footage from an aluminium warehouse in Spain is being re-shared after showing how quickly accidental fires can spread
Reports suggest the fire started accidentally due to a catastrophic failure. With many remarking the blaze looked like it opened a "portal to hell."
The aluminum industry in the United States in 2023 produced 860 thousand metric tons of aluminum from refined metal ore (primary production), at six smelters. In addition, US industry recycled 3.4 million tons of aluminum (so-called secondary production aluminum).[1] Total annual imports of metal and alloy for use in secondary production stood at 2.6 million metric tons in the year to August 2023, with the previous decade seeing a fundamental shift toward recycled production

In the absence of gravity, flames will tend to be spherical, as shown in this NASA experiment
In the absence of gravity, flames will tend to be spherical, as shown in this NASA experiment
Great balls of fire: How flames behave in space
It’s a process called molecular diffusion, and it produces spherical flames that are different from their Earthly counterparts in more ways than one. Not only do they burn much slower and for longer periods of time, but they also survive on less oxygen and clock in at less than 900 degrees Fahrenheit — a fraction of the heat given off by most terrestrial flames.
And yet, there’s still much scientists don’t understand about how fire operates in microgravity. Are certain materials more flammable than others? What’s the best way to extinguish a rogue flame?
These questions are critical for the safety of astronauts already living and working in the International Space Station (ISS), and will only become more important as humans prepare for longer space voyages. Luckily, NASA scientists are on the case.

Fish Rain in Iran - Fish Fall from the Sky
A "fish rain" took place in Iran. When tornados pass over water, they pick up the fish and drop them over land.
The lluvia de peces (lit. 'rain of fish'), also known as aguacero de pescado (lit. 'downpour of fish'),is a phenomenon that has been occurring yearly for more than a century in Yoro, Honduras, in which fish are said to fall from the sky. It occurs up to four times in a year. It has attracted the attention of scientists, as well as documentary coverage by the History Channel in the United States
The explanation generally offered for the rain of fish is meteorological, often speculated to be strong winds or waterspouts, as is commonly proposed when attempting to explain similar occurrences of raining animals.
Fish are opportunistic, just like other living creatures. If food presents itself in any form, they will eat it. Sure, that food may have been their best swimming buddy the day before, but today he's lunch. It's all part of that great circle of life
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish
