Thanks for the question. What a fascinating idea. Shouldn't think we'll see it any time soon but great to know it's being seriously considered.
What do you think of the possible EM Drive? Is it a scam, or does it really "break" Newton's Third Law?
Geez Walt hard to tell from reading about it on these sites. Would be a great break through !

I find it fascinating that it appears to work in the lab ... But shouldn't on paper. So they're going to actually put one in space to see if it works "in real life".
Maybe we'll have to rename it "Newton's Third Theory" instead of "Law".
