Answers: What are black holes and how do they work?

• black holes
• Hawking radiation
• event horizon
• black hole information paradox
• gravitational waves
• Sagittarius A*
• M87 black hole

What it concludes

• Black holes are about 6 billion times the mass of the sun and have a Schwarzschild radius larger than our solar system.
• Gravitational wave detectors like LIGO can detect tiny shifts in spacetime caused by colliding black holes.
• According to Stephen Hawking's calculation, black holes emit Hawking radiation, meaning they glow at a very low temperature and eventually shrink and disappear.
• The black hole information paradox arises because laws of physics state information is never destroyed, yet calculations suggest black holes destroy information.
