Black Holes Explained: What Is a Black Hole? How They Form?
A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it’s completely black, and hence it’s called a black hole. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light.
When a massive star dies, it leaves a small but dense remnant core in its wake. If the mass of the core if more than around 3 times the mass of the sun, the force of gravity overwhelms all other forces and a black hole is formed.
A black hole is not just empty space; in fact, it’s a great deal of amount packed into a very small area. Think of a star which is 10 times more massive than our is squeezed into a sphere which has the diameter equal to the size of New York city. The result will be a celestial object whose gravitational field is so strong that nothing, not even light, can escape it. This is why black holes are named so, because they are pitch black!
“Black holes explained” is a short-animated video explaining the science of ‘what is a black hole’ and ‘how black holes are formed’? The “black hole picture 2019” is a recent event that occurred in April 2019, which involved the release of the first ever black hole picture to the general public. But what are black holes? How are black holes formed? What’s the explanation behind the black hole theory?
