Microscopic black holes have long hovered at the edge of theory, forming only in exquisitely balanced states. Now physicists ...

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 ...

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

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

Black holes crashing together may be revealing clues about dark matter hidden across the universe. Physicists created a new ...

Some black holes could have tamer origins—in the folds of unusual "spacetime crystals" that researchers finally managed to ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only have ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the ...

How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...
