Physics

Quantum entanglement allows two particles to be linked regardless of the distance separating them, meaning a change in one instantly affects the other – even if they're light-years apart. elaborate share

Physics

Most of the matter in the universe is dark matter, which we can't see or directly interact with. elaborate share

Stringtheory

Physics

String theory requires more than the usual three spatial dimensions and one time dimension; it posits the existence of extra, curled-up spatial dimensions unseen at macroscopic scales. elaborate share

Physics

Wormholes, if they exist, could potentially allow for faster-than-light travel, but traversing one might require navigating exotic matter with negative mass-energy density – a substance we've never observed. elaborate share
