Who knows, maybe I'm not using the behemoth equation that requires it.. :/ I was using the basic formula already mentioned earlier on this thread. I got something many orders of magnitude greater than the newtonian solution. AFAIK aerospace companies and even nasa don't use relativistic equations when designing aircraft. And if they do its because they're appeasing a bureaucracy of pedantic asshats! Relativity is completely irrelevant when you're dealing with velocities below 100,000 m/s! In fact my entire scenario has nothing to do with relativity so you can forget that . . . but honestly I have to question whether bremsstrahlung would be significant at non-relativistic velocities. I was just responding to your style of bringing up things which other people don't understand in an attempt to sound sophisticated. For instance, I never asked about any of the stuff you brought up and whenever you do bring up something relevant I shoot it down with half a second of consideration. You can do all the blackboarding you want, thats not how everything is done.
