Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the ...

For centuries, we’ve believed gravity holds the universe together. But what if that’s the biggest misunderstanding in science ...

The birth of the universe has been a question that has puzzled scientists for centuries. In a groundbreaking study published ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question that's difficult to answer, but physicist Melvin Vopson of the University ...

Since conventional explanations have failed to pony up dark matter, one physicist is looking towards the unconventional. In a series of two papers, physicist Stefano Profumo of the University of ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern ...

File this one under "fun to think about, probably not changing your day job": a new study just dropped that suggests gravity itself might be the smoking gun that our entire universe is one big ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density ...
