Terahertz radiation can penetrate many non-metallic materials like clothing and packaging, making it useful for security screening but also potentially for medical imaging.

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.

The grandfather paradox, a classic time travel conundrum, is actually a plot device more than a scientifically sound problem, as it assumes a fixed, linear timeline that might not exist in theoretical models of time travel.

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

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.
