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
Photonic chips, similar to microchips but using light instead of electricity, can process information significantly faster and more energy-efficiently than their electronic counterparts.

Relativity predicts that time passes slower for objects moving faster relative to a stationary observer – a phenomenon known as time dilation.

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.

There's no single, universally agreed-upon "beginning" of time. Our current understanding of physics suggests a point called the Big Bang, but what, if anything, came before it remains a mystery.
