Most scientists think that everything that we know and experience began with the Big Bang, 14 billion years ago. But how can ...

(PhysOrg.com) -- Suppose at some point the universe ceases to expand, and instead begins collapsing in on itself (as in the “Big Crunch” scenario), and eventually becomes a supermassive black hole.

Imagine we had somehow filmed the whole history of the universe and you could play the movie in reverse. It would start off much as things stand today: a vast and elegant web of galaxies and nebulae.

The big bang wasn’t a bang in the traditional sense—but it was nonetheless the start of important things: for one, space; another, time. Thirdly, it began the conditions and processes that eventually ...

In episode three of What's in a name we look at how ideas can be lost in translation when physicists try to name the unknown. Categorizing things is central to science. And there are dozens of systems ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the singularity at the origin of the universe. By adding higher-curvature terms to ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

The farthest spacecraft from Earth has shut down another instrument in the hopes of buying time for an upgrade that could boost the aging probe’s impressive lifespan.

We all know that everything kicked off when the Big Bang exploded our universe into reality, right? Well, not necessarily. A compelling new theory of the creation of our universe suggests that it may ...
