> After I found all this out, I concluded space travel isn't THAT hard, assuming you have a way to accelerate constantly at 1g for 22 years (that is the hardest part actually), you can get anywhere in the galaxy in a human lifetime, no need for generation ships, cryogenics or other crazy tech. Unfortunately, there is also a kind of rocket equation for constant 1g acceleration, and if I remember correctly it's not really doable for any realistic amount of time, even with matter/antimatter reaction drives.
