Can anything get away from a black hole?

Answer 1

Yes, a black hole can capture another black hole. Astronomers believe that a supermassive black hole exists at the center of our own Milky Way galaxy, and they also believe that they exist in the center of some other galaxies. Additionally, the supermassive black hole probably did not become supermassive by just "eating" only stars.

The star density of many galaxies is greatest at the center, and the probability that black holes form there is fairly high. Further, multiple black holes have a higher probability of forming, and then of interacting ("hooking up") in such a "close" volume of space.
Yes. Black holes can attract each other and merge if they are close enough.

Answer 2

Once something has crossed the event horizon of a black hole, it cannot escape due to the overwhelming gravitational pull. However, objects outside the event horizon can move away if they have enough velocity to overcome the gravitational attraction.

Answer 3

Answer #3: Yes and no. Think of gravity as a net and think of a gravitational singularity as a tiny, tiny point (In reality, infinitely small) with infinite density and immense but finite mass. Drop this object on top of the net and you end up with near 90° curves in the net. Once the curves reach 90°, that is the event-horizon, commonly termed "point of no return." It is at this point that the speed required to reach escape velocity is faster than the speed of light which is an impossible speed. Just before the curves reach 90°, matter can escape as long as it is able to reach escape velocity (Highly unlikely the closer matter comes to the event-horizon). The math and physics behind gravitational singularities is well beyond our current means of understanding. In addition to answer #1, that is purely theoretical. Some scientists believe that when a gravitational singularity evaporates, everything that went in is compressed into an object of Planck length (~1.61x10^-35m). The difficulty in knowing is that when a black hole is about to evaporate, it releases a large burst of Hawking radiation, in a magnitude much larger than it released during it's life. This radiation stops us from seeing the remnants of a gravitational singularity and the chances are that by the time the radiation dissipates enough, whatever remnants that may have been there would be long gone, possibly orbiting a nearby planet, star or galaxy, large asteroid, anything.

Only if u could travel with more force than the black hole and have strong enough armor 2 save urself from distorting both of wich r so far impossible.





Guess my age? Yes anything can get away from a black hole and eventually does. Because even a Black Hole Dies and when it does the matter floats away to another force.

Answer 4

In that case, there would be a combined black hole, with a mass almost equal to the sum of the mass of the individual black hole. The collission would generate intense gravitational waves - some of the mass in the black holes would escape as gravitational wave energy.

Answer 5

That really depends how close, and how big the black hole is. In many respects, the situation is the same as if an object approaches another mass, that doesn't happen to be a black hole. In many cases, an object that gets close to a black hole would get faster and faster as it approaches, but if it doesn't hit the black hole (the event horizon) head-on, it would have enough momentum to escape the black hole's gravitation again, and get farther and farther away (while it slows down again, of course). If the object hits the event horizon, it will stay inside the black hole. With smaller black holes, it is also possible for an object, that gets too close to the black hole, to get destroyed by the tidal forces of the black hole, even if it was not on a collision course with the black hole.

Answer 6

We're not certain, since the only interaction any black hole has is by gravity. Probably they would merge, becoming one even stronger black hole. Some theoretical physicists believe that when two black holes merge, or perhaps when one forms, that a pulse of "gravity waves" may be emitted. Such a pulse ought to be detected from very great distances. However, we have not yet detected anything like this, but we haven't been looking for very long yet; and it's possible that our "gravity wave" detector is not yet properly designed. Time will tell.

Answer 7

Black holes don't reach out and suck things in.

As an extreme example, if you were asleep in your bed and our sun suddenly

became a black hole, you wouldn't notice anything. The earth would continue to

orbit the black hole, just as it orbits the sun now.

The black hole is an object with a certain amount of mass ... roughly the same mass

as a medium-large star or a giant star. Anything that was in orbit around the star

could continue in orbit just fine around a black hole with the same mass.

Where it starts to get interesting is one mile or ten miles or a hundred miles or

a thousand miles from the black hole ... places that used to be deep inside the

star, but now they're outside the black hole. That's where the gravitational force

between the black hole and anything else is so enormous that the familiar laws

of Physics go haywire, and not even light can escape.

But at 'normal' distances from it, where planets and comets and asteroids typically

are, it makes no difference whether you're in orbit around a star or a black hole.

Oh sure, it's cold and dark around a black hole, but the hole isn't going to reach

out and suck anything in.

Answer 8

No - In fact, the hypothetical concept of a wormhole is the pairing of black hole with a white hole to create a "shortcut" (tube or tunnel) through SpaceTime. Also known as an Einstein-Rosen Bridge, a wormhole is a hypothetical topological feature of SpaceTime, which, if it were even possible, would be too unstable to be maintained. Therefore a wormhole would not be "suck up" by a black hole, because the wormhole is an extension of a black hole. Rather wormholes would independently destabilize and evaporate, allowing the black hole to continue on into existence.

Answer 9

It will just get sucked in and pulled to another part of the Universe. It will supposedly take you to another place of the universe in FAST time.

You would explode from the lack of atmosphere, then your remains would be crushed into a microscopic size.
the super gravitational pressures would compress you.
unsure of a good way to answer this, but as the nuclear fuel is expended, the star gets denser, until it "implodes" further yet.
the gravitational pull is so strong that the light cannot escape, and is pulled back inside. Since no light emits, there is "nothing " to see.

Answer 10

This is believed to actually happen - two supermassive black holes (each of a mass of millions or billions of times the mass of the Sun!) colliding, after their corresponding galaxies merge.

The black holes would circle each other for quite a while, losing energy in the process (due to gravitational waes). When they actually collide, it is believed that, due to the magnitude of the collision, they will release a large amount of energy through gravitational waves - shock waves that will ripple through the surrounding Universe. So far, despite ongoing efforts, these waves have not been detected yet.
