[00:00:00]so the problem is the fastest spaceship we've ever launched the fastest thing if you aimed it for the closest exoplanet right let's go to Proxima Centauri it's called Proxima Proxima b because it's close right it's the closest that's why this we gave get gave it that name uh huh it is four light years away cause the other one is what is it 40 50 light years I forgot the number but it's tens of light years Proxima Centauri right there right aim your fastest thing we have ever launched take you 70,000 years so you gotta figure out how to defy your biology or invent a wormhole and I'm gonna I'm gonna bet on the wormhole
