The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

The universe has no brain. It has no gray matter, no nervous system, no neurons firing electrical impulses—and yet, that ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Astronomers have proposed a new theory to suggest why our universe is expanding at an accelerating rate. That our universe is expanding is in wide agreement, though how exactly that process happens is ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

Given how unfathomably large the universe is, it is perhaps understandable that we haven’t yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we ...

Aug. 29 (UPI) --Early universe observations by the James Webb Space Telescope cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, ...

Throughout the existence of life on Earth, we have always been plagued with the question — are we alone? Regardless of humanity’s contrasting beliefs, there has always existed the undeniable fact that ...

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.

It’s broadly agreed that the universe is constantly expanding. The why of it all, though, is a little more mysterious. Most researchers agree that dark energy is responsible for our universe’s ...
