Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate – as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists are preparing to ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Two teams of researchers working independently of one another have come up with an experiment designed to prove that gravity and quantum mechanics can be reconciled. The first team is a pairing of ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

"By understanding quantum gravity, we could solve some of the mysteries of our universe — like how it began, what happens inside black holes, or uniting all forces into one big theory." When you ...

(PhysOrg.com) -- Because of the absence of gravity, fuels burning in space behave very differently than they do on Earth. In this image, a 3-millimeter diameter droplet of heptane fuel burns in ...
