Haha, yeah, we'd definitely need some serious breakthroughs in longevity to make it to Alpha Centauri alive. A 400-year trip is wild to even think about

Even a trip to Mars, which I believe will take 9 months is hard to comprehend.

Imagine being on an airplane that long. People want to get off after a few hours.
