The Concept of a Mirror Universe A universe that flows backward in time sounds more like science fiction than a scientific ...

A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in ...

Forget one Big Bang — try many. A bold new theory pokes holes in the popular origin story, suggesting the universe evolves through a series of lightning-fast bursts, rewriting what we know about ...

Eternal universe Before the Big Bang theory was developed, the prevailing consensus among scientists (and really anybody who thought about it for any length of time) was that the universe was just ...

Physicists have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests that, at extremely small scales, space and time behave differently from ...

What if there is more than one cosmological agent for dark energy? This mixture would have strange effects in our universe, making it potentially detectable with upcoming surveys.

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...
