Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Earlier this year, researchers discovered that photon-emitting atoms moving through a vacuum experienced a friction-like force never detected before. This was not just unexpected but it also ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

Besides quantum mechanics, another interesting topic in physics is relativity. Let’s take a look at it! Of all the force fields, the gravitational field is the one man has known for the longest time.
