Only 10 days before Stephen Hawking died, the famous physicist handed over to the publication publisher his last scientific paper, which he worked with colleague Thomas Hertog.
The paper entitled “A smooth exit from eternal inflation?” Has just been published in the journal “Journal of High Energy Physics”.
Hawking and Hertog formulate a new theory about the creation of the universe, which can answer some of the questions that have not been answered so far.
According to the theory known earlier, the universe a little less than 14 billion years ago began to spread from, and this spread was extended to today.
According to one interpretation of this theory, our universe is one of the parallel universes, which has infinitely many.
In their paper, Hawking and Hertog are relying on the theory that tries to merge quantum physics with Albert Einstein’s gravitation and theory of relativity.
In their interpretation of the theory of the eternal propagation of the universe, there are boundaries according to which our understanding of the way in which time passes doesn’t makes sense.
On the basis of these boundaries, the new theory takes a limited number of universes in which the same laws of physics as in ours apply.
Physicists could seek evidence of the existence of other universes using gravity wavelength measurement tools created during the original spread of the universe.
The current instruments for searching for gravitational waves are probably not powerful enough to find evidence that would prove this theory of Hawking and Hertog.
“The theory that parallel universes are very similar, gives us the hope that we will be able to fully understand cosmology,” says Hertog.
In the future, the creation of new more perfect instruments for searching for gravitational waves is likely to be the task of the European Space Observatory.
