The experiment shown here was carried out on the International Space Station to see how combustion happens in a 0g ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this familiar force remains one of the biggest puzzles in physics.

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

This Star Trek concept ignited a dream that humans could one day travel faster than the speed of light. Now physicists are ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...
