How do you know what happens in a black hole?

Answer 1

They know because of the scientific explanations of black holes. Most people think they don't exist since you can't see them. That's why they are called "black" holes. But since not even light can escape a black hole, you can see it if light looks like it's being pulled towards something and is moving in a circular-spinwheel-like motion.

Answer 2

When a giant star collapses, there is a possibility that it could form a singularity, a single point in space with infinate mass, zero volume, and infinate gravity. We can't see Singularity because they are covered by a dark region called the Event Horizon. Because it is dark and things seem to "fall" into the dark region, it was dubbed a "black hole". We now know that black holes have incredibly strong gravitational pulls, so strong that not even light can escape. The singularity pulls everything within its gravitaional reach towards it. When an object reached the event horizon(black hole), it disappears. What is theorized is that the singularity's gravitional pull is so massive that molecules are broken up into the smallest sub-atomic particles. Everything basicaly "dematerializes" at the event horizon, creating the dark region that we see.

Answer 3

You would be able to see the accretion disk, then nearby orbits being effected and then you would see matter DE atomize and become a stream of particle's that are pulled into the center of the Black Hole.

Answer 4

Nothing, for a few reasons.

First, black holes do not "suck" at all. This is a common misconception. Actually, they just have a very strong force of gravity due to their incredible density.

Second, the event horizon is not a physical object or place, but a boundary in what we are able to observe. This has to do with escape velocity - basically, past the event horizon, no light can escape because it's not traveling fast enough. Things are still presumably happening past the event horizon; they're just blocked from our view.

Third, the event horizon surrounds a black hole. You can't have a black hole with no event horizon (because the density of the black hole leads to an escape velocity higher than the speed of light, so there will always be a point at which we can no longer observe), and you can't have an event horizon without a black hole (because the concept of an event horizon is that approaching the black hole we can't see things).

Answer 5

Technically we are not 100% certain that black holes exist. First a bit of introduction. The idea of black holes, as we understand them now, was first introduced through calculations of general relativity. At first the idea was dismisses as a curiosity of math but without any true bearing on reality. Later work, though, suggested that the core of a dying massive star could collapse to form a black hole.

The first direct evidence of a black hole came in 1978 with observations of the system Cygnus X-1. The system, which emits powerful X-rays, consists of a giant star and a compact object about 15 times the mass of the sun. By our current understanding of physics the only explanation for the compact object is that it is a black hole. The X-rays occur as gasses from the star are pulled into an accretion disk around the black hole and heated to millions of degrees before either being swallowed by the black hole or ejected at nearly the speed of light. Other, similar systems have been discovered elsewhere.

Observations of the center of our galaxy suggests that it holds and unseen object about 4 million times the mass of the sun. The only known explanation is that this mass is a supermassive black hole. The quasars observed in distant galaxies are also believed to be caused by supermassive black holes.

Answer 6

Scientists study black holes by observing their influence on surrounding matter, analyzing light emissions, and detecting gravitational waves. Through these methods, they can infer behavior and characteristics, such as the intense gravitational pull that traps light and matter within the event horizon. However, due to the extreme conditions inside a black hole, direct observation is not possible.

Answer 7

you don't you just die suddenly as the black hole kills you.

Answer 8

You would feel a great change in gravity, the the atmosphere would be stripped off the planet, and you die.

Answer 9

Black holes emit radiation, and while you can't see the black hole itself, you can see its effect (Stars being sucked up, etc.)
