According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square of the distance between them – the inverse square law. However, as Most ...

In his discussion of accelerated motion on page 60 of "The Meaning of Relativity," Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Yesterday, I wrote about the core concepts needed to understand quantum ...

It's a problem that Albert Einstein identified more than 100 years ago. It's a problem we could be on the cusp of solving, or that could take another century to untangle. And the problem is that we ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of special ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time – and ultimately paved the way for some even bigger ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...
