Black holes are massive cosmic objects created when large stars collapse in on themselves. They have immense gravity that sucks in everything around them, even light. While invisible, scientists believe black holes exist at the center of most galaxies based on their gravitational effects. They were first proposed by Einstein's theory of general relativity in 1915 as points in spacetime where gravity becomes infinite.
2. Black hole is massive hole that sucks
everything in.
Black holes go against basic physics.
They are created by explosion of a star.
When star explodes there are gases
and clouds around the explosion area.
Then those gasses and clouds are
pulled together and collapsed. At last
black hole is formed.
