The efficiency of a heat engine is fundamentally limited by the temperatures at which it operates; you can never completely convert heat into work.elaborate
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.

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

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.

Quantum entanglement allows two particles to be instantaneously correlated, regardless of the distance separating them – a phenomenon Einstein famously called "spooky action at a distance."
