Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time: Reading time 3 minutes ...

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

I was surprised that C&EN would devote two columns to the letter by Harvey Carroll on the matter of atomic weight versus atomic mass (C&EN, Jan. 24, page 4). I realize the majority of the informed ...

European scientists are turning an aircraft into a laboratory that simulates lunar gravity to prepare astronauts and ...

Researchers have found that bone and muscle mass are regulated by the altered gravity. The experiments were done in space using Kibo, an ISS module developed by JAXA, and on the ground. An ...

Earth’s mass is about 6 million million million million kilograms, say our readers – and it wouldn’t be a great idea to be in the vicinity if too much mass were added Let’s start by realising that ...
