“I do believe he was really fond of it.”Hertog travelled to Cambridge to work on the theory with Hawking and towards the end, communication became very difficult, he said. But in the latest work, Hawking and Hertog challenge that view. Instead of space being filled with pocket universes where radically different laws of physics apply, these alternate universes may not actually vary that much from one another. “Stephen himself said that this work was the area he was most proud of,” said Malcolm Perry, a colleague of Hawking’s at Cambridge University. Hertog believes that his work with Hawking is one small step towards a theory of our cosmic origins that physicists could ultimately test.
