Why Is Interstellar Travel Physically Impossible? | Neil deGrasse Tyson

The stars are calling — but physics says we can never answer. In this mind-expanding breakdown, Neil deGrasse Tyson explains why interstellar travel is not just hard, but physically impossible with anything resembling known science. From the unbreakable light-speed wall of Einstein's relativity to the staggering energy wall, the tyranny of the rocket equation, deadly time dilation, and relativistic dust grains that hit like nuclear bombs, Tyson lays out every barrier between humanity and the stars. He also takes on warp drives, wormholes, and generation ships — separating real physics from science fiction fantasy. If you have ever dreamed of visiting another star system, this is the reality check the universe demands. The final chapter reveals the one loophole physics might still allow. 2.
