Stephen Hawking’s last paper has finally appeared in print and presents some theories on the Big Bang and the multiverse it created. This paper has been available on the internet since Hawking’s death, but it was submitted to the journal and awaited approval. Hawking wrote the paper in collaboration with a professor at the University of Leuven in Belgium, Thomas Hertog.
Hawking presented an interesting theory on the multiverse
One Big Bang theory claims our universe is actually part of a multiverse. This means that, when Big Bang happened, it created an infinity of universes. The same theory claims new ones keep appearing. However, such a huge number of universes makes quite a hard case for scientists. There are too many factors to consider, so it’s hard to tell why our universe ended up like this.
Hawking and Hertog cultivated the same idea. Its implications were that the multiverse actually evolved randomly, without a clear pattern, and this made the two scientists upset. Therefore, they put up this paper where they tried to reduce the number of universes. From all that are possible, they selected those who share some properties with our own.
The theory is really interesting, but it can’t be proved
There have been certain physical conditions available when the Big Bang occurred. These influenced the future properties of our universe as soon as it came into being after the Big Bang. Hawking and Hertog thought these properties might have materialized into other similar universes. By understanding this basic theory, we might learn more about this multiverse.
As soon as the paper went public, many people made suppositions that it could have earned Hawking the Nobel Prize. However, there are many who disagree. The theory indeed brings a new perspective on the multiverse and the birth of our own universe. However, all these claims cannot be verified at the moment. Since the two scientists didn’t discover how to find all these similar universes, the paper presents only speculations.
