Interisting (sic) indeed, however we are told that there are only about 10^80
electrons in the universe and this is somewhat smaller than 10^1200 tons of
fuel necessary to circumnavigate the Universe. It would seem that a much more
efficient fuel is necessary.

Has anybody calculated the amount of matter that would have to be gathered
from space for a ship of reasonable size to keep accelerating at 1g?
