I created this thread to get into the details:

How long for a spacecraft to reach Tau Ceti at 1 g?

Inspired by the Project Hail Mary thread. Tau Ceti is about 12 light years away. I have questions: If you accelerated at 1 g all the way there (not worrying about having to go into some kind of Tau Ceti orbit), how long would it take for the spacecraft to make it there, from the perspective of Earth and from the perspective of the ship? If you had to actually do something at Tau Ceti, I guess you would accelerate at 1 g to the midpoint and then decelerate at 1 g for the rest of the way. How…

No matter how fast the astrophage lets you accelerate, humans can only handle so much g-force. Anyway, I don’t want to further hijack this thread, so physics answers over there, please.
