What does it look like in a black hole?
Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But the holes can nevertheless be seen. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas.
How long does it take to fall into a black hole?
16 seconds
What would happen if time ran backwards?
If time ran in reverse, all the laws of physics would work the same. The Second Law states that over time, everything moves from an ordered state to a disordered state. It’s the only physical law that can’t go backwards.
What is beyond the event horizon of a black hole?
They’re only visible when they’re feeding on stars or gas clouds that stray too close to their boundary, called the event horizon. Beyond the event horizon lies a truly minuscule point called a singularity, where gravity is so intense that it infinitely curves space-time itself.
Do white hole exists?
If a speculative theory called loop quantum gravity is right, then white holes might exist. Sailors have their krakens and their sea serpents. Physicists have white holes: cosmic creatures that straddle the line between tall tale and reality. Yet to be seen in the wild, white holes may be only mathematical monsters.
What is a green hole?
The green, or putting green, is the culmination of a golf hole, where the flagstick and hole are located. Getting the golf ball into the hole on the putting green is the object of the game of golf. Every hole on every golf course in existence ends at the putting green.
Does space have water?
Water is abundant in space and is made up of hydrogen created in the Big Bang and oxygen released from dying stars. Earth was moulded from rocks that came from the inner solar system where the fierce heat of the Sun would have boiled away any water.
How does water behave in space?
A water drop and air bubble in outer space. Consider what would happen on Earth: The air bubble, lighter than water, would race upward to burst through the surface of the droplet. In space, the air bubble doesn’t rise because it is no lighter than the water around it—there’s no buoyancy.
What happens if you cry in space?
Astronauts can’t cry the same in space as they do on Earth. Your eyes make tears but they stick as a liquid ball. In fact, they sting a bit. So — space tears don’t shed.” Unless an astronaut wipes that water away, tears in space can form a giant clump that can break free of your eye, as The Atlantic explained.
