There is a place in the universe where the ordinary rules simply stop working. Time slows to a crawl. Space curves back on ...

A team from Vienna and Frankfurt has found a formula describing a strange phenomenon: Space and time can form a kind of "crystal" that may turn into a black hole. The results are described in Physical ...

What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

Researchers have developed a method for steering microscopic swimming robots using light patterns and the principles of Einstein's theory of relativity. The technology is a potential first step toward ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...
