Stephen Hawking’s Last Paper (about the Multiverse Theory) Has Been Published

The multiverse theory is the subject of Stephen Hawking’s latest published paper.

 

The last research paper completed by the world-renowned Stephen Hawking has recently been published, and it takes aim at the contentious multiverse theory. The famous scientist passed away this year on March 14.

 

What is the Multiverse Theory?

 

According to this idea, the cosmos, here dubbed the “multiverse,” continues to expand forever after the Big Bang. However, it also stops in certain places, which can be compared to bubbles in an ocean. Our universe is one such “bubble”, for example.  But there might also be others where the laws of physics may work very differently from our own.

In his last research paper, co-authored by Thomas Hertog from Belgium’s KU Leuven, Stephen Hawking argues that the multiverse theory should not be dismissed, but rather trimmed.

 

“Our findings imply a significant reduction of the multiverse, to a much smaller range of possible universes,” he was quoted by the University of Cambridge as saying when he submitted the paper.

 

According to Hertog, their idea is that the cosmoses are, in fact, finite, not infinite. As such, only certain kinds of other universes can exist. He said that this is based on string theory, a kind of theoretical physics.

Hertog also stated that this should make the multiverse theory easier to predict. In turn, this should also create the possibility of its being scientifically tested. The researcher specifically said that he believes that measuring gravitational waves could help either prove or disprove it.

 

General Opinions on this Controversial Theory

 

Many researchers are dismissive of the multiverse theory. Among them is Frankfurt Institute for Advanced Studies’ Sabine Hossenfelder. She states that most serious researchers ignore the idea because it is “completely useless” to speculate about.

Before his death, Stephen Hawking himself said that he was “never a fan” of the theory. This might perhaps explain why this paper wants to modify its premises.

Hossenfelder said that the new ideas that Hawkins and Hertog published are only a minor variant of the basic theory. She also adds that they include some new presumptions as well.
