more-inWith a science paper published after his death, Stephen Hawking has revived debate on a deeply divisive question for cosmologists: is the universe just one of many in an infinite, ever-expanding “multiverse”? According to one school of thought, the cosmos started expanding exponentially after the Big Bang. In most parts, this expansion or “inflation” continues eternally, except for a few pockets where it stops. These pockets are where universes like ours are formed — multitudes of them that are often likened to “bubbles” in an ever-expanding ocean dubbed the multiverse. The underlying question is whether we can achieve a deeper understanding of where the laws of nature come from, and whether they are unique,” Mr. Hertog added.
