The answer to this question depends on how you think about quantum gravity, explains physicist Vlatko Vedral ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological ...

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 ...

Eleven times wider than Earth. Over 300 times more massive. And a million times more terrifying. Jupiter may look like a beautiful ball of swirling clouds, but on the inside, it is a gaseous inferno.

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Blue Origin will launch its first suborbital rocket launch of 2025 today — and attempt a wild spin trick to mimic the moon's gravity during the flight — but if you want to see it live, you'll need to ...
