Imagine a scenario in which the Big Bang happened twice. Imagine a scenario in which it happened numerous, maybe even an infinite number of times. Imagine a scenario in which it never even happened at all. It may sound crazy, but all these scenarios are possible.
Recently, several astronomers and physicists have called into question the universe’s age and whether the Big Bang even happened. They argue that the Big Bang is contradicted by recent evidence from the James Webb Space Telescope and that there is a better explanation for why our universe appears the way it does.
Some alternative theories suggest the universe isn’t expanding at all, or if it is, the age of the cosmos is perhaps twice as large as previously thought.
A few weeks ago, I had the pleasure of dissecting these different scenarios at the Thinking Beyond webinar series featuring renowned physicists Paul Davies, Sara Walker, and Maulik Parikh from the Beyond Center for Fundamental Concepts in Science at Arizona State University.
