What happens to the gravitational force you experience near a black hole?
Because the matter in a black hole is so dense, the force of gravity within the black hole becomes immensely strong, attracting everything within a certain radius and not even allowing light to escape. Well, one of the most fascinating and unsolved mysteries of the universe is what happens inside a black hole.
What is the Schwarzschild radius of a black hole?
Parameters
| Object | Mass | Actual radius |
|---|---|---|
| Observable universe | 8.8×1052 kg | 4.4×1026 m (46.5 billion ly) |
| Milky Way | 1.6×1042 kg | 5×1020 m (52.9 thousand ly) |
| TON 618 (largest known black hole) | 1.3×1041 kg | |
| SMBH in NGC 4889 | 4.2×1040 kg |
What would happen if you entered a black hole at the speed of light?
It is known as the point of no return, or the exit door of the universe. Whatever passes the event horizon, including you, can never return because the black hole’s pull is too strong to escape, even if you’re traveling at the speed of light.
Can a black hole escape at the speed of light?
It’s true that the escape velocity for a black hole is the speed of light. But if you have something like a spaceship that can provide its own acceleration, you never have to actually move at the escape velocity in order to escape. The real reason why it’s impossible to escape is because the space inside a black hole is curved in on itself.
What happens when material falls into a supermassive black hole?
Material falling into a supermassive black hole powers the brightest continuous sources of light in the universe, and as it does so, forms a corona around the black hole. This light – which is X-ray light – can be analyzed to map and characterize a black hole.
What is the event horizon of a black hole?
If the event horizon of a black hole is the distance from the center from within which light cannot escape, imagine a person with a flashlight falls into the black hole. He points his flashlight in a precisely radial direction and turns it on. Now there is a light ray moving outward at the speed of light.
Why can we see black holes in space?
It is another strange characteristic of the black hole, however, that makes this observation possible. “The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself,” Wilkins explained.
