While gravitational waves might spread out evenly over space, the amplitude (which goes as 1/r) is the key quantity for detectors, not the energy (which goes as 1/r^2). M. Pössel/Einstein Online ...

How 5,000 Pencil-Size Robots May Solve the ... AI designs 50 gravitational wave detectors that could ... Dark energy is the yet unproven force that competes with gravity and causes the ...

If I let the gravitational potential energy at an infinite distance be zero Joules, then: Yes, the gravitational potential energy in this way would always be negative. Don't worry.

Albert Einstein "drops the mic" on physicists a century later 07:01. A century after Albert Einstein predicted their existence, gravitational waves have finally been detected, tiny ripples in the ...

“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 ...

But the supermassive black holes are just one candidate for a source of the massive gravitational hum. "We found the choir, but we don't know who's singing in it — the pop stars are the ...

Researchers have discovered that in the exotic conditions of the early universe, waves of gravity may have shaken space-time so hard that they spontaneously created radiation.

If gravitational waves experience gravity, that means that gravitons don't just interact with the energy-carrying particles of the Standard Model, but there is a graviton-graviton interaction as well.

That energy may have been able to energize electromagnetic fields, causing them to emit light powered by gravity alone. As far as we know, our universe kicked off a long time ago by the Big Bang .

After decades of planning and political drama, the LIGO detectors first tried to hear gravitational waves in 2002; after eight years of quiet, the detectors were shut down in 2010 and further ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.
