How does a star die?
Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.

How fast would a black hole destroy Earth?
D Astrophysics, University of Leicester, said a 1mm black hole would still have a mass of 10 percent that of Earth. If it was to hover on Earth’s surface, its gravitational pull would cover a third of the planet, tearing it up at 12 kilometres per second.
What happens if Earth goes into a black hole?
If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. Eventually, some time later, any object at rest — no matter how far away from the event horizon it initially was — will cross that horizon and encounter the central singularity.
What if a black hole hit the sun?
If a black hole like Cygnus X-1 were to stray near the Solar System, within a light-year or so, its gravity would cause chaos. The orbits of the outer planets and comets would be significantly and possibly disastrously altered, and this would in turn threaten the orbits of the inner planets and even the Sun.

What is inside a black hole NASA?
A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The gravity on the inside of the circle is so strong that nothing can escape—it sucks in everything, even light. That’s why it’s black!
