"FTL is impossible" doesn't seem like an extraordinary claim at all, but actually quite an ordinary one. The natural world seems to obey a light-speed limit every time it's been tested. Sure, it might be wrong, but as far as claims go it has a lot going for it, both experimentally and theoretically.
