Nuclear Spacecraft Fuel to Run Out By 2018

[Earnest Cavalli]

i know and accept that, however, seeing as our basis for believing in its impossibility is purely theoretical i feel a bit uneasy sayinf for certain that it is literally impossible. afterall scientific opinions change all the time.

Except that it's only impossible in theory because it's so literally impossible in reality. We are left to theorize over how difficult it would be because we can't even come remotely close to being able to test the whole thing out.

It's like saying "theoretically, a dinosaur would try to eat you."
