How Black Holes Work: The Onion Explains

In summary, a black hole is a region in space with a strong gravitational pull that traps everything, even light. It is formed when a massive star dies and its core collapses. The size of a black hole can vary and is determined by the amount of matter it has consumed. If someone were to fall into a black hole, they would experience "spaghettification" due to the intense gravity. Nothing, not even light, can escape from a black hole, making it impossible to directly observe.

Forgive them. Their best writers snagged a pen on the spacetime fabric and were never seen again.
 

FAQ: How Black Holes Work: The Onion Explains

What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It is formed when a massive star dies and collapses in on itself.

How do black holes form?

Black holes form when a massive star runs out of fuel and can no longer produce enough energy to counteract the force of its own gravity. The star then collapses, causing a black hole to form.

What happens if you get too close to a black hole?

If you get too close to a black hole, the gravitational pull will become stronger and stronger. Eventually, the force will be so strong that it will stretch and compress your body until you are torn apart. This process is known as spaghettification.

Can anything escape from a black hole?

No, once something crosses the event horizon of a black hole (the point of no return), it cannot escape. This is because the gravitational pull is so strong that not even light can escape.

How do scientists study black holes?

Scientists use a variety of tools and techniques to study black holes, such as telescopes, satellites, and computer simulations. They also study the effects of black holes on their surroundings, such as the movement of stars and gas around them.
