Scientists experimentally confirmed what we’ve known to be true for half a century—darkness can “travel” faster than light.

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

Light that twists as it travels and materials whose internal order is knotted like a pretzel are starting to collide in the lab, and the result is a new class of strange, topological effects. Instead ...

The universe is packed with riddles, but few are as stubborn or as fascinating as dark matter. First proposed in 1933 by astronomer Fritz Zwicky, this elusive substance refuses to play by the rules: ...

Strong light–matter coupling has emerged as a transformative concept in modern physics, whereby the interaction between confined electromagnetic fields and material excitations is engineered to yield ...
