No problem.

Actually its more like 25 million tons.  Yes fusion can incredible amounts of
energy just from a little bit of fuel, but the energy needed to shove a ship
that heavy to those speeds is far FAR greater.  <otherwise we'ld go faster!

Problem is, as far as we can figure out, the magsails wouldn't produce enough
drag to slow the ship down fast enough.

Problem is no one knows how to do "cryofreeze".  People talk about it a lot in
science fiction films and books, but all actual attempts have killed all the
test animals.  Also as a practical matter someone has to keep the ship

In our case we don't have enough engine power to go faster, so its not much of
a problem.

Ok, glad you liked it!  ;)
