In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Astronomers have directly observed a spinning black hole twisting spacetime, confirming a century-old prediction of ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

When a star gets too close to a black hole, the gravity of the black hole changes what happens next in really big ways. They give us a chance to see h.

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 ...
