A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

Presenting a new perturbative method to deal with the gravitational N-body problem in general relativity. A novel approach to construct global and local reference frames leads to explicit ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO) could potentially detect gravitational waves from an alien ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to ...

A New Force Model From this experiment, I have a new idea for the way the gravitational force works in Angry Birds Space. Essentially, the force looks like this: ...

This graphic shows how cosmic strings formed after a phase transition in the early universe might have created gravitational waves detectable by future observatories.

Since the two gravitational forces from the mountain is sideways (relative to "down"), the force from the string must be diagonal. Now you just need to know the mass and distance to the mountain.

New gravitational-lensing study hints at problems for dark matter models On a fine scale, the Universe seems lumpier than it should be.

Where F is the force of gravity, m1 and m2 are the masses of two objects and r is the distance between them. G, the gravitational constant, is a fundamental constant whose value has to be ...

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves ...
