Einstein’s strangest optical illusion has been captured—thanks to lasers, a cube, and a bit of artistic inspiration.

New research challenges the long-accepted notion of singularities in black holes — the point where physics allegedly breaks ...

Physicists have demonstrated the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp ...

To do this, they introduced a novel mathematical object they call the space-time dimension field. This field acts as a kind ...

Fast-moving objects don’t always look the way you’d expect. When something travels near the speed of light, strange things ...

In the quest toward finding the correct theory of quantum gravity, physicists have been testing the holographic principle which, they say, is a key property of any valid theory of quantum gravity.

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity ...

Research from Aalto University could bring together the four fundamental forces of nature under a singular framework ...

When an object moves extremely fast – close to the speed of light – certain basic assumptions that we take for granted no longer apply. This is the ...
