Two particles prepared together stay correlated at any distance. Bell tests killed local hidden variables. The no-communication theorem keeps that correlation from becoming a faster-than-light phone.

A planet orbiting another star is a firefly next to a searchlight. We find it by the tiny dimming when it crosses the star — then read its air from the starlight that filtered through.

Satellite clocks tick faster in orbit and slower from speed. Ignore relativity and your phone’s map drifts miles a day.

You cannot see a black hole directly. You can photograph its shadow — if you build a telescope the size of the planet.

The carbon in your cells and the oxygen in your lungs were forged inside a star that died before the Sun existed — then delivered to a molten Earth by rocks that never became planets.
