That’s one of the answers to how you could go to the stars: go sloooooow as in slow down your cognition and metabolism so the trip doesn’t take long.
Ents could fly to the stars no problem.
Makes me wonder if there might not be a bunch of star faring “slow life” out there that we don’t notice for the same reason a hummingbird doesn’t notice trees growing.
