In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery ...

Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time had two temporal dimensions. That is the implication of new theoretical ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their ...

The James Webb Space Telescope has revealed a rare "Einstein ring," revealing two distant galaxies in an optical illusion ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy.

The physique that changed the concepts of space and of time with the theory of relativity and the famous AND=MC2Nobel ...

Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of quantum computer – and it could also lead to new insights into the quantum rea ...

Sidney Perkowitz uncovers the pioneering work of the German physicist and philosopher Grete Hermann, who sparred with the ...

I was first introduced to Brownian motion 50 years ago in medical school as I peered through a microscope and saw nonliving particles moving randomly on a microscope slide. This phenomenon was first ...

There's no question that Albert Einstein was one of the greatest minds of his or any generation, but there was one problem he ...

On Monday, the European Space Agency (ESA) launched the ACES set of atomic clocks to measure the effect of gravity on the passage of time.

Quantum entanglement is challenging researchers to understand how photons seemingly influence each other instantaneously.
