Hawking's final paper reveals thoughts on mystery of the cosmos

The late professor Stephen Hawking's final theory on the origin of the universe has been published today in the Journal of High Energy Physics.

In order to carry out the research with Stephen Hawking on the multiverse, Hertog traveled to Cambridge - and towards the end, communication became very hard.

A recent multiverse theory from Stephen Hawking suggests that the multiple universes that make up reality might not be too different from our own.

But if the Big Bang were to birth an infinite number of possible universes, all with different laws of physics, majority would be hostile to the stable existence of the matter that makes up stars, planets and human beings - and of physics itself as we know it.

But Hawking said he wasn't a fan of that theory - and other physicists agree - in part because it's impossible to test.

The new Hawking-Hertog theory states that, from the Big Bang (the moment of formation of the cosmos), the Universe was formed as a vast and complex hologram, so that other universes very similar to ours can exist.

In the new theory, instead of space being filled with countless universes where entirely different laws of physics apply, these alternate universes may not actually vary that much from one another.

"The problem with the usual account of eternal inflation is that it assumes an existing background universe that evolves according to Einstein's theory of general relativity and treats the quantum effects as small fluctuations around this", Hertog said in a statement published by the University of Cambridge.

"However, the dynamics of eternal inflation wipes out the separation between classical and quantum physics".

This idea "resolved a difficulty with Einstein's theory that suggested that the universe began almost 14 billion years ago but said nothing about how it began", says the BBC. It was never said between us that this would be the last paper. The theory was revisited and updated with more powerful mathematical techniques used in string theory, where reality is described through the interaction of one-dimensional objects called cosmic strings.

Hertog says that this approach could help physicists in future to work on developing a complete theory that explains the entire universe and how it really came to be.

"When we trace the evolution of our universe backwards in time, at some point we arrive at the threshold of eternal inflation, where our familiar notion of time ceases to have any meaning", Hertog said in a news release.

New theory claims universe is finite " We predict that our universe, on the largest scales, is reasonably smooth and globally finite.

Stephen Hawking died this March in Cambridge at the age of 76, having suffered from a rare form of motor neuron disease since 1964. "'A Smooth Exit from Eternal Inflation?"
