The Small Hole behind the Big Bang

We have all heard of Black holes and how destructive they can be. Black holes are phenomena that even young kids know about now. What if I told you that black holes have a counterpart that many people have not even heard of?

White Hole: In simple terms, it is the opposite of a black hole. In a Black hole, it is impossible to escape, as we are sucked in and torn down until we are turned into atoms. Whereas, a white hole is a hypothetical region of space-time that is impossible to enter from the outside. This is because they have a force that pushes matter away or outside of it, in a repulsive manner, which is unlike the gravitational pull that is found in the case of black holes. Although, their event horizon is similar. In a black hole, the event horizon marks the point where the velocity needed to escape is equal to the speed of light. Which means that we cannot escape it after this point. Similarly, a white hole’s event horizon marks the point that you cannot go past because of its repulsion. A study from 2014 says that once a black hole evaporates to a degree where it is unable to shrink any further because space-time cannot be squeezed into anything smaller, the dying black hole rebounds to form a white hole.

Now we come to the theory that suggests that the Big Bang was caused by a white hole. The Big Bang is the event that gave birth to the universe. The universe can be broken down into much smaller regions of space called galaxies.

In the 1920s, Edwin Hubble discovered that besides the Andromeda galaxy, which is the closest to ours, all the light that came from other galaxies had experienced a cosmological redshift. This could be explained as light that is stretched and has an increased wavelength. This suggested that all other galaxies were moving away from ours and causing the universe to expand. This would mean that the universe has been expanding constantly since the big bang. Meaning that the Big Bang had repelled or pushed all matter away from it. The property of strong repulsion is where the big bang and a white hole are the same. Therefore, the theory would indicate that a white hole and the Big Bang had the same starting point, which means that the white hole could have caused the matter to be expelled away from it.

Despite this, the universe is still a large mystery to us. This is only one of many plausible theories that give us information on the universe. We cannot confirm any theories regarding white holes since we cannot yet confirm their existence. This is because, if a white hole were to be observed, it would be in the instant in which it repelled all matter. The odds of this happening are very slim. Therefore, the concept of white holes remains just a theory regarding the secrets of our universe.
