If black holes aren’t already crazy enough, imagine if you see one of these….
Most people know what a black hole is, at least its most basic definition: places of the universe where the density ( concentration of mass) is so great and gravity is so strong that not even light can escape its deadly pull. They are born from the collapse of huge stars such as super or hypernovae, that, once burned all of their fuel, start consuming its layers until reaching the nucleus and proclaiming its irreversible death.
So, when do we start talking about white holes?
According to some complicated ( I mean, very, very complicated) math, physicist showed that, if the event horizon (the limit that separates the “outside” from the “inside’ so no information can get through) of a black holes had no mass, then, it would be possible to have a weird structure called a white hole.
White holes are virtually the opposite of black holes. Instead of sucking all the mass in, it sends everything out. They would be “at the other end” of a black hole, sending all the planets, stars or whatever is caught to somewhere else, probably another universe.
The whole thought of white holes is so appealing because it could explain the Big Bang. What if we were actually born from a white hole? Did it disappear after billions of years? Or is it still there?
But, again, we only know of their theoretical basis. Nobody has ever detected one. However, some scientists do dream of making this possible and are currently working on this.
