Today I was talking about electric potential. My favorite analogy for electric potential energy is gravitational potential energy. But electric potential is something different. Electric potential ...

Throughout the universe, there are several underlying principles that we consider to be constants; for example, the speed of light in a vacuum. So many different aspects of our understanding of the ...

We now have the most precise estimates for the strength of gravity yet. Two experiments measuring the tiny gravitational attraction between objects in a lab have measured Newton’s gravitational ...

Dark matter is an enigmatic form of matter not expected to emit light, yet it is essential to understanding how the rich tapestry of stars and galaxies we see in the night sky evolved. As a ...

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar ...

Ripples in space-time caused by the violent mergers of black holes have been detected, 100 years after these “gravitational waves” were predicted by Albert Einstein’s theory of general relativity and ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic ...

Changing times: JILA researchers measured time dilation within this tiny cloud of strontium atoms. (Courtesy: R Jacobson/NIST) Two independent teams of researchers in the US have used differential ...

A team of astronomers monitoring interstellar object 3I/ATLAS have found something a little surprising. Our third confirmed interstellar visitor appears to have changed color for the second time.

Australian energy storage company Green Gravity and mining business Wollongong Resources, majority owned by Indian steel giant Jindal Steel and Power Ltd., have signed an agreement to deploy ...

The gravitational constant is the key to unlocking the mass of everything in the universe, as well as the secrets of gravity. When you purchase through links on our site, we may earn an affiliate ...
