5 min read“If you had a telescope and looked down at them near the surface of the black hole, everything would be going in slow motion,” Neil deGrasse Tyson explains, unpacking a fan’s question about the time dilation in Interstellar. On Miller’s Planet, where minutes equal years for the crewmate left on the ship, the light pulses from the planet would arrive stretched—every second on the planet would appear as two or three seconds to the observer above. This isn’t a trick of the light; it’s a direct consequence of Einstein’s general relativity, where gravity warps the rate at which time unfolds. The same principle applies to GPS satellites, which must pre-correct their signals for relativity so that our clocks on Earth’s surface stay synchronized with theirs in orbit.
