Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

Forbes contributors publish independent expert analyses and insights. I cover the physics of nothing, everything, and the stuff in between. Gravity causes galaxies to rotate. Astronomers can study the ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...
