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 ...

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 ...

(Philipp Tur/iStock/Getty Images Plus) Right on the brink of black hole formation, spacetime can get downright peculiar. This ...

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 ...

Spacetime is often described as the stage on which the universe unfolds, a four-dimensional blend of space and time that bends, stretches and shifts as matter and energy move through it. However, ...

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

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 ...

To square Albert Einstein’s General Theory of Relativity with quantum mechanics requires some currently unknown physics, and that’s led some scientists to question if Einstein’s theory could use some ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

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 ...
