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 ...

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 ...

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 ...

The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...

Time really does move faster on Mars, but the breakthrough that confirms it did not come from a spacecraft’s stopwatch.

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.
