Most of us are aware of the black hole, what does it mean and what exactly it does and most recently scientists have revealed the first-ever image of a black hole. But have you ever thought is there any other type of structure similar to a black hole. Exactly, black hole is not the only type of colossal structure out there in the space. There is one more fascinating phenomenon in the universe which astonishes us that is a white hole.

"Because according to the laws of general relativity – If eternal black holes exist in the universe, then a white hole should also exist."

From what I understand about Einstein GR, yes white holes could exist and some use them to create the universe, running in reverse from a black hole while an expanding universe unfolds and new stars and galaxies form. *eternal black holes* is a subject of much debate, e. g. Hawking, Kip S. Thorne et al, quantum gravity and black hole evaporation times.

I'm not sure too many people actually know what a black hole is, honestly. Most are too caught up on the "hole" part, thinking of it that because of the intense gravity that draws everything in, that that material then gets funneled down a shaft or (examples) because.. It has to go somewhere, right?

No. A black hole is for all intents and purposes, the extremely dense remnant of a star that want supernova and continued to be.crushed by their own gravity until they create a singularity, a point in space which contains a huge mass within an infinitely small area of space. The increasing differential in gravitational attraction ends up destroying all trapped in it's gravity well, like smashing a malfunctioning office printer with a.baseball bat until there's nothing left to see, but on a subatomic level.

So the name "black hole" is a misnomer; it's black because of the effect it's gravity has on light as it pulls it in, but there is no hole.

But don't we say before the big bang their was a point of singularity? With all the mass in a single point.
 
In the Big Bang model using Einstein GR, extrapolating the expansion of the universe into the past - results in a singularity. The problem in GR, a singularity for the starting point for the origin of the universe explains nothing. In GR, the singularity can destroy everything, all laws of science, etc. so there is no way to evolve out of the singularity into the present, observable universe. Kip S. Thorne book makes this clear and so do other reports. This is why string theory and quantum gravity and inflation is used to model what happened before the Big Bang - to avoid the *naked singularity* for the origin of the universe, otherwise a miracle took place :)

do you know this very well?!) "who saw her?" I think you can see it like the light at the end of a tunnel when you die)
