Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

A revolutionary new model, gaining traction among physicists, suggests our entire universe might be a vast, expanding black hole that emerged from the collapse of a larger, older "parent" universe.

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest. Based on several recent dark energy ...

The Big Bang Theory is nearly perfect, except for one glaring problem - where is all the lithium? According to the theory predictions there should be over three times as much lithium i ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

The Universe may not have started with the Big Bang, but instead “bounced” out of a massive black hole formed within a larger “parent” universe, according to a new scientific paper. Professor Enrique ...

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

Dark matter, the mysterious substance that makes up roughly 80 percent of all the matter in the universe, may have been forged before our cosmos was even born. Scientists have long theorized as to ...

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 ...
