Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

Astronomers have detected one of the darkest objects ever seen at a record cosmic distance—only with the assistance of ...

Mass is mass is mass. Physicists have three different definitions of mass, all thought to be equivalent. Measurements of the distance between Earth and the moon confirm that two of those masses are ...

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 ...

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 3 minutes Despite keeping us ...

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.
