General relativity fails at describing the interior of black holes, so scientists have turned to loop quantum gravity theory, which sees space-time as a mesh of tiny loops.

In it, she uses a music box and a Möbius strip to explain space-time, showing how the two axes of musical notation (pitch and tempo) correspond to space and time.

Here’s everything you need to know about the newly detected cosmic gravitational wave background in simple language.

A novel theory of "wavy space-time" suggests the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

This way of portraying space-time changes fundamental physics, especially in extreme settingssuch as black holes or the Big Bang -- which is thought to have birthed the universe.
