A black hole has a boundary, called the event horizon. It is where gravity is just strong enough to drag light back, and prevent it escaping. Because nothing can travel faster than light, everything else will get dragged back also. Falling through the event horizon, is a bit like going over Niagra Falls in a canoe.
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.Jun 4, 2014
After that, gravity will drag you toward the singularity at the speed of light and ultimately spaghettify you. No one knows what happens beyond the event horizon, and astrophysicists suspect that the physics we understand here on Earth breaks down inside of a black hole.Dec 12, 2014
Do black holes also die? ... Yes, even a black hole has a finite life. This discovery came about when Stephen Hawking discovered that black holes should radiate energy due to quantum mechanical processes. This radiation is called Hawking radiation.Jun 27, 2015
That is, at least not until you reach the singularity at the heart of one of these objects. However, time will appear to slow down for you as seen from observers on the outside and once you are past the event horizon – the point of no return – there is no way that anything, not even light, can escape the black hole.Dec 16, 2014
An observer who remains outside the black hole can't see through it, but that's not your problem. As far as you're concerned there is no horizon. ... In fact, in a big enough black hole, you could live out the rest of your life pretty normally before dying at the singularity.May 25, 2015
In computer networking, a packet drop attack or blackhole attack is a type of denial-of-service attack in which a router that is supposed to relay packets instead discards them. This usually occurs from a router becoming compromised from a number of different causes.
Our Sun is actually too small to end up as a black hole. ... If the Sun were somehow compressed enough to become a black hole, it would be less than 6 kilometers (well under 4 miles) across. It would exert no more gravitational force on Earth or the other planets in the solar system than it does now.
