If you asked an astrophysicist today to describe what happened after the Big Bang, he would likely start with the concept of “cosmic inflation.” Cosmic inflation argues that right after the Big Bang — we’re talking after a teeny fraction of a second — the universe expanded at breakneck speed like dough in an oven. But this exponential expansion sho...
Last July, Hawking and Hertog presented this new theory of the multiverse during a conference at the University of Cambridge to celebrate Hawking’s 75th birthday. Their idea hinges on the so-called “holographic principle.” As its name suggests, the principle argues that the universe is a hologram. The principle hails from string theory, the branch ...
If time is a removable string, then there could be places or moments in the history of the universe that operate without it. In Hawking and Hertog’s newest theory, time is the fly in the ointment, keeping cosmic inflation from aligning with general relativity. So they treated the moments after the Big Bang, when inflation occurred, as a timeless st...
