Just imagine if one day you hear about a twin of the black hole. All must have heard
about the Big Bang theory, due to which the universe exists. The white holes or also
known as “Black hole's neglected twin”, seem similar to the big bang theory. Just exactly
opposite to the black hole which sucks in all the things around it, the white hole spits out
everything inside it, although there is no evidence on the existence and formation of
white holes, there are numerous theories based on it. White holes are described as a
black hole's "time reversal, "If we see a video of a black hole sucking in things in reverse
playback, it seems like a black hole throwing out things just like a white hole. In standard
relativity, a white hole is a theoretical place of space-time and singularity that cannot be
entered from out of doors, despite the fact that strength-matter, light, and information
can escape from it. In this sense, it's far the reverse of a black hollow, which can be
entered simplest from the outdoors and from which electricity-count numbers, mild and
statistics can't escape. White holes appear inside the concept of eternal black holes.
They entice rely upon like every other mass, however, gadgets falling towards a white
hole might never certainly reach the white hole's occasion horizon. While in a black hole
it is a point of no exit whereas a white hole is a point of no entry! From afar a white hole
just looks like a black hole, It contains mass, it would spin, and it has a ring of dust and
gas that gathers around the hole. If crew members of a spaceship watch it from afar, it
will seem like a black hole, until they see the white hole throwing out things so they will
say, “Ahh that's a white hole". One such theory says that a white hole is related to a
wormhole. A wormhole in space is such that if you enter from one part of the universe,
you travel faster than the speed of light and reach some other unknown part of the
universe. Rather than being the "exit" of a wormhole, they may be a slow-motion replay
of the formation of the original black hole. They say that the beginning of this wormhole
is the black hole which sucks in all the objects and the other exit end which throws out
everything is the white hole! Black holes are formed from the death of a star, and
according to a theory, white holes are formed when a black hole dies and becomes as
small as 1 microgram and would not follow the law of physics that is the 'General Theory
of Relativity. With regard to its small size, it would no longer have the gravitational pull,
and at the same time, it would have all the cosmic objects in its interior that it had
sucked in when it was a black hole, after a while, it would start to throw out all the
objects it had swallowed up, just like The Big Bang Theory! But unfortunately till now
there is no such evidence on the existence of White holes, scientists still keep searching
for evidence and facts on the formation of white holes. But just imagine on earth if there
was such a wormhole with one end of the black hole at your house where you step into
and the other end that is the white hole in your school, you wouldn't be worried about
getting late to school unless you're lazy enough to get out of bed!
