Reactionless Thrusters for real???

[Sassy Psionic Space Squid]

There are a vast number of things that can in theory be tested, but isn't, because the odds of success are too low to be worth the effort.

That's not the point of science at all.

And at any rate, I would agree that it's not worth the time if nobody had tried to test this or the initial experiments showed negative results. However, actual positive experimental results from an independent party warrants others attempting to reproduce the experiment, if only to demonstrate that there was in fact an error of some kind.

Insisting that nobody should bother because it was probably an error is rather bullheaded.
