Everyone knows Andromeda is "2.5 million light years away." Almost nobody realizes that's not even the full story. Our actual nearest galaxy is a small, disrupted dwarf sitting more than 100 times closer — and even that is hopelessly out of reach. In this video: the real math behind interstellar travel times using Voyager 1's actual speed, why even 10% light-speed propulsion still means million-year journeys, why relativistic time dilation doesn't save you, why theoretical ideas like Bussard ramjets and warp drives don't solve the problem, and the far more unsettling truth — the accelerating expansion of the universe means most galaxies we can currently see are already permanently, physically unreachable, no matter how advanced our technology ever becomes.
