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.

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

Gravitational waves are tiny ripples in the fabric of time and space that are created by some of the universe's most powerful events such as colliding black holes.

“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 ...

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 .

Gravitational energy is often harnessed and used as a clean power source for consumption. For example, hydro energy is energy produced by the force of falling water, ...

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.
