Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

The slower growth of gravitational wells and the accelerating expansion might share the same underlying cause.” In so many ...

It’s widely known as a gravitational slingshot, though most scientists refer to it as a gravitational assist, and it’s an ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

“Primordial gravitational waves from inflation may lead to an appreciable contribution to the energy density of dark radiation in the early Universe, which is a prediction that can be tested in ...

Rubin Observatory’s LSST will help scientists study the gravitational lensing they’ve already seen, but it will also help them greatly increase their catalogue of examples. Scientists know of about ...

Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height ...
