One tonne of shielding. One milligram of uploaded crew having fun in virtual reality. But just escaping doesn't do much good. Use several tonnes of antimatter and you could get near the speed of light.https://twitter.com/michael_nielsen/status/956765039062470656 …

At 100% conversion efficiency, it ought to cost ~10^2 dollars to produce a milligram of antimatter from more standard power sources. I don't know what the best achieved conversion efficiencies are, though.
These numbers seem remarkable, almost too good to be true. Admittedly, conversion efficiency, storage, shielding etc a big problem.

I get about $2000 per milligram at today's US gas prices. In Frink notation: https://frinklang.org/fsp/frink.fsp?fromVal=3.00+dollars+%2F+%28gallon+gasoline%29&toVal=+dollars%2F+%28mg+c%5E2%29&keep=1#calc …

What about slowing down the virtual crew's perception of time so as to make some interstellar distances seem subjectively short. Or even a whole interstellar society. Might this be even easier and cheaper?
