A new theory suggests our universe and a time-reversed twin could emerge together. This quantum approach avoids singularities ...

Theoretical physicists James Hartle and Stephen Hawking, for example, proposed that rather than having a strict beginning as we would understand it, the universe evolved out of a "no-boundary" state ...

An IIT scientist proposes a twin universe born alongside ours, where time flows in reverse. This theory challenges the Big ...

A key element missing from these approaches is the incorporation of a mechanism that naturally accounts for a flat universe, as observed today. In classical cosmology, spatial curvature plays a ...

This might change our understanding of the universe. Scientists have developed a theory that eliminates the problem of ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up nearly 70 ...

Cosmic inflation is a faster-than-light expansion of the universe that spawned many others ... either in on itself like a ball (“positive” curvature) or out on itself like a saddle ...
