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 ...

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 ...

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 ...

Albert Einstein might be astonished to learn that NASA physicists have applied his relativity theory to a concept he introduced but later disliked namely that two particles that interact could ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

Wolfson, a physics professor at Middlebury College, takes the fear out of Einstein's relativity theory in this brisk piece of pop science. The author uses a tennis game on Venus and a cup of hot tea ...

A rare 54-page manuscript featuring preliminary calculations for Albert Einstein’s general theory of relativity sold for about $13 million at auction in Paris Tuesday to an unknown buyer — almost four ...

Dennis G. Hall was formerly Vice Provost for Research, Dean of the Graduate School, Professor of Physics and Professor of Electrical Engineering at Vanderbilt University. For at least forty years, ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...
