Re: superhero space navigation

Leonard Erickson skreiv:

Well, I did some quick calcs and if we assume constant jerk sufficient
to reach the moon in an hour, then for a 10AU trip the turnover
velocity is 0.24c.

If the time to the moon is only 30 minutes then turnover velocity for
the 10 AU trip is around .48 c.

Constant jerk is pretty crazy, especially if you postulate he can do it for essentially as long as he wants to.

Constant _acceleration_ like "1G indefinitely" drives are already deep black magic and unphysical if powered by onboard matter pretty quickly. (even total mass-energy conversion can't do it for VERY long)
