At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Gravity can exist without mass.” It’s a statement that upends a century of astrophysical dogma and, for some, sounds as ...

The simpler model still meets the established requirements for a robust unified gravity theory. Even if this theory does not prove revolutionary, it shows that new ways of thinking are possible.

Researchers at Aalto University have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the standard model of particle physics, opening the door to ...

Measuring Stellar Gravity There are three traditional methods for estimating a star’s surface gravity: photometric, spectroscopic and asteroseismic.

So some astronomers favor an alternative, such as Modified Newtonian Dynamics (MoND) or the modified gravity model. And a new study of galactic rotation seems to support them. The idea of MoND was ...
