The reason for this is that everybody approaches the topic with a different angle and it becomes very hard to figure out who is correct but speaking in an obscure language and who is incorrect but ...

An independent way of measuring mass in the universe is gravitational lensing. General relativity, our best theory of gravity, predicts that mass bends light. In gravitational lensing, light from a ...

It is now thought that the source of this anomaly was a phase transition in which one mineral’s structure was altered.

What is gravity without mass? Both Newton's revolutionary laws describing its universal effect and Einstein's proposal of a dimpled spacetime, we've thought of gravity as exclusively within the domain ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

Researchers claim sound waves do carry mass – gravitational mass. This implies that a sound wave not only is affected by gravity but also generates a tiny gravitational field. Our findings are valid ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

What could be more familiar than gravity? Drop something and gravity pulls it to the floor, right? And in school we learn that gravity is what guides the moon in orbit around Earth, and Earth in its ...

In everyday conversation, and even on our site, we treat the terms mass and weight like synonyms. But scientifically, the two are related but very separate. The mass of an object is an intrinsic ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our ...
