Bridging the quantum world to relativity Einstein spent the rest of his life, without success, pursuing ways to integrate his theory of general relativity with quantum mechanics. While it is tempting ...

Albert Einstein's general theory of relativity predicts so much about the universe at large, including the existence of gravitational lenses or "Einstein rings." And yet his famous equations struggle ...

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space ...

A peer-reviewed paper published in The European Physical Journal C presents a modification to Einstein’s general relativity that eliminates the singularities associated with the Big Bang and Big ...

LAST month, I answered a reader question about space-time expansion. They wanted to know what space-time is expanding into, given that we scientists tend to analogise with a balloon that is being ...

Physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...

Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, the U.S.' largest Large Hadron Collider research institution. He also writes about science for the public, including his ...
