Can you escape out of a black hole?
The gravitational pull of a black hole is so strong that nothing, not even light, can escape once it gets too close. Moving at close to the speed of light, these particles ricochet off the event horizon and get hurled outward along the black hole’s axis of rotation.
Can a black hole destroyed?
Black holes are among the most destructive objects in the universe. There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process.
Will most of the Galaxy eventually fall into a black hole?
No, the popular picture of a black hole as a huge vacuum cleaner sucking in everything around it is inaccurate. Black holes, even the one at the center of our galaxy, are very small. Only if you get very close to a black hole’s event horizon does it start pulling everything in. So no, most of the galaxy will not eventually fall into the hole.

How can we see a black hole?
Jerry: The black hole itself can’t be seen but if it has a nearby star circling it, some material from that star is stripped off and just before it gets sucked into the black hole, it gives off enormous radiation. That’s how we observe it.
What is the nearest black hole to Earth?
Jerry: Our nearest black hole is probably an object called Cygnus X-1. It’s about 30,000 light years away from us and is one of the brightest objects in the X-ray sky. CraigNASA: Can you see a black hole with a normal telescope?
