14:08Why Humanity Will Never Leave The Solar System
Kurzgesagt spends fourteen minutes dismantling its own back catalogue of galaxy spanning futures, and the argument is built on numbers rather than mood. Put a crew aboard a ship as fast as the Parker Solar Probe at 635,000 km/h and you reach Mars in two weeks, Pluto in a year, and the true edge of the solar system in 2,500 years. Grant the optimistic fusion or antimatter case of 20% the speed of light and the distances collapse, but empty space turns into ammunition: a single iron atom carves a damage track, a dust grain hits like a grenade, and a golf ball sized rock arrives with more than double the Hiroshima yield. Even then a realistic 40 year trip reaches only 8 light years, into a 25 light year neighborhood holding 34 stars, 6 brown dwarfs, and almost nothing worth the journey. The video closes by handing you the counterargument: in 1903 the New York Times predicted powered flight was millions of years away, and was wrong 69 days later.
