If someone is making a claim, especially a remarkable claim, it is their responsibility to provide evidence for their claim. If they cannot, or if their evidence is such that it cannot pass peer review, something stinks, and one should be highly skeptical.
This is not a case of "no one has shown X, therefore X should be dismissed". It's "P has claimed X, but has not shown evidence to justify their claim, therefore their claim should not be believed." If someone holds a position, presumably they had a good reason to do that, and one can ask for that reasoning and evidence (and ask that that reasoning and evidence be verified by peer review.)
Dude, Dr. Bussard died not long after the video I linked to, so maybe you don't realize you're kind of disparaging a man who's no longer here to defend himself.
In any event, I didn't mean to upset you. I'm not a physicist, nor some sort of "true believer", I just think Dr. Bussard's ideas deserve more research before we can rule them out so definitively. Maybe I'm a gullible dufus. On the Internet.
