For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

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 ...

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.

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth by ...

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 ...

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant advancements in our understanding of black holes, cosmology and quantum gravity. Plus, ...

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 ...

However we do not have to worry about the universe-obliterating Big Rip yet because if it happens it would happen in about 22 ...

Are we living in “The Matrix” in real life? In the 1999 science-fiction film, Neo discovers that the universe is a simulation — but one scientist believes that the idea isn’t all fiction. Dr. Melvin ...
