What happens when stars go into a black hole?
The black hole immediately swallows half the star’s matter while the rest arcs away in long streamers. These rapidly fall back and settle into an accretion disk that steadily feeds material into the black hole, growing so hot that it emits copious x-rays.
Why is gravity stronger in a black hole?
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space.
Do black holes have more gravity than stars?
A Black Hole does not have more gravity than the star it came from. At least not until it feeds and gathers more total mass into itself than was present in the original star. One of the properties of gravity is that its pull gets stronger the closer to you get to the center of mass of the gravitational object.
What happens to a star when it goes into a black hole?
A good chunk of the material that was left within the star goes blasting outward, fast and hot enough to barrel into any gas and dust nearby and produce X-rays. It’s really only the very core of the star that stays put, and can be compressed into the black hole.
Does a black hole come from a supernova?
However, if we let nature produce a black hole, the black hole that is produced at the end of a supernova explosion is actually significantly less massive than the star that it once was. Part of the drop in mass between star and black hole comes in the years before the supernova, when the star typically sheds a sizable fraction of its mass.
Can light escape a black hole once it is created?
Light could obviously escape the gravity of the star and the black hole is made from the dead star but, once the black hole is created, light can no longer escape. Does the mass somehow increase at the death of the star?
Can an object shrink to become a black hole?
There’s a certain mass-dependent radius – the Schwarzschild radius – to which an object must shrink in order to become a black hole. Newton’s Law of Universal Gravitation, which you stated, doesn’t apply in its standard form to light.
