What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

Scientists have described for the first time how spacetime could crystallize into a tiny black hole.

Using just a pen and paper, a team of scientists has calculated how space and time could crystallize to form tiny black holes ...

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 ...

(Philipp Tur/iStock/Getty Images Plus) Right on the brink of black hole formation, spacetime can get downright peculiar. This is where familiar physics can become unnervingly strange, and ...

“Research on warp drive now has a more focused target: the engineering of spacetime that doesn’t rely on negative energy.” ...

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

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 ...

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 ...
