2:13:16Why Traveling at Light Speed Would Destroy You Before You Even Arrive
A two hour Calm Space night documentary that dismantles science fiction's favorite assumption: that light speed travel is a technology problem waiting on a better engine. Working entirely from established physics, it shows the barrier is an asymptote, not a wall. Time dilation severs travelers from home, the interstellar medium becomes a relativistic particle beam, the cosmic microwave background blueshifts into hard X-rays on the bow, and even a perfect antimatter rocket needs propellant quantities 21 orders of magnitude beyond world production. The conclusion is quietly optimistic anyway: the speed of light is the speed of causality, the stars remain reachable at perhaps 10% of light speed, and the realistic path runs through slow unmanned probes and a civilization patient enough to wait.
