What is the black hole and white hole?

“All is not lost if you fall into a black hole - you simply pop up in another universe” Stephan is hawking.

Most famously, black holes were predicted by Einstein’s theory of relativity, which shows when a massive star dies, it leaves behind a small dense remnant core. Its gravitational force becomes strong enough to pull off the outer gasses of stars and grow a disk around called the accretion disk.

Gasses from this disk spiral in the black hole. These gasses off from the stars heat up to a large extent producing X-ray lights. Measuring these X-rays, we are up with the concepts of primordial, stellar, and supermassive black holes.

The second law of thermodynamics (entropy of isolated system either remains constant or increases) is stated true as per black holes, but violated by white holes.

White holes are an antigravity and unstable concept. Their phenomenon differs from known yet and we are marveled by them.

Time traveling is possible in the future and past as well. Hence, according to Einstein’s theory, white holes may exist taking us to the past life of black holes.

Hawking’s radiation theory exclaims that after consuming a matter, the event horizon of a black hole increases. After the formation of black holes, they continuously radiate depending upon their mass. These radiations are due to space near the event horizon (not from the black hole).

Black holes never die, as they consume matter, and matter can neither be created nor be destroyed. It is predicted that at the end of a black hole time span, they transform themselves into white holes.

If this prediction stood correct, we would be answered by the remaining questions of the big bang theory.

As per Stephan hawking, black holes and white holes are connected by singularity, which can lead us to another universe.

14 June 2006, an explosion of gamma rays was recorded, named GRB060614. This supermassive explosion is completely unknown to us. It remained longest up to 102 sec and then vanished. Shocking behavior forced us towards the phenomena of white holes.

Such predictions, theories, calculations, and backing observations, left us with questions such as, “Are we in a black hole?”
