>If we can't travel faster than the speed of light
using existing understanding of Nature - we can. At least the Universe provides the example of galaxies traveling with faster than the speed of light relative to each other. The same machinery is suggested in the
The opponents state that the energy requirement of the drive is higher than the whole Universe's energy. Obviously it is wrong statement as we already have whole galaxies mentioned above and whose faster than light speed obviously takes less than the whole Universe's energy.
Galaxies are not actually moving faster than light. The distance between them is growing at a rate that would suggest FTL speeds because the universe is expanding.
Galaxies are not spaceships. Just because the natural expansion of the universe affects galaxies (and everything else) doesn't mean it's possible to artificially expand and contract the universe.
