The big bang got its name from a man who thought the theory was total nonsense

The big bang is one of those theories that even the most casual student of science finds familiar and, at least at face value, is fairly easy to understand: we know the universe is expanding out in all directions, and some physicists figure there must have been a point when that whole thing started. All the matter in existence was packed up into a tiny, hot, dense little nugget, and then suddenly it wasn’t. Bang went the universe, and it’s been growing ever since. So it might surprise you to learn that the name of this popular origin story came...

Stephen Hawking thinks he knows what happened before the beginning of time

Neil deGrasse Tyson’s show Star Talk is ending its fourth season with a bang—a big one. The big one, to be precise. The show, filmed at the American Museum of Natural History in New York City, features famous astrophysicist Tyson interviewing famous-for-things-other-than-physics folks through the lens of science. For this Sunday’s season finale, Tyson’s guest is arguably the only physicist more famous than he: Stephen Hawking. Tyson asked Hawking your standard softball interview question: what was around before the big bang? In other words, what happened before the moment the universe began? Check out his answer: “The boundary condition of...

Wait... What came before the big bang?

Cosmologists used to think the universe was totally timeless: no beginning, no end. That might sound mind-melting, but it’s easier on the scientific brain than figuring out what a set starting point would mean, let alone when it would be. So some physicists have cooked up alternative cosmological theories that make time’s role seem a little less important. The concepts are as trippy as those black-light posters you had in college. Wait a minute… Flowers of the multiverse The main reason some physicists obsess over the beginning of the universe is because so much evidence points to there being one....

Astrophysicists: "The Big Bang is not the beginning of the universe and we known it for 40 years"

To think that the universe and everything in it were born at the time of the Big Bang is “one of the biggest misconceptions in science” according to an astrophysicist and scientific author. This is an “attractive and beautiful” image that explains much of what we see, but, “unfortunately”, it is also “incorrect”, and scientists “have known for almost 40 years,” argues in an article for Forbes astrophysicist and scientific writer Ethan Siegel, who calls it “one of the greatest misconceptions of the universe”. According to Siegel, the original idea suggests that the universe emerged from a hot, dense state,...

The Big Bang is Out – Scientists Propose the Big Bounce Theory

Did the universe start with a bang or a bounce—or something else entirely? The question of our origins is one of the thorniest in physics, with few answers and lots of speculation and strong feelings. The most popular theory by far is inflation, the notion that the cosmos blew up in size in the first few fractions of a second after it was born in a bang. But an underdog idea posits that the birth of this universe was not actually the beginning—that an earlier version of spacetime had existed and contracted toward a “big crunch,” then flipped and started...
