If there are no rocket launches and satellites, is x-ray and gamma ray astronomy a hoax? Are they doing it from high-altitude balloons? If the balloons are high enough to be above the atmosphere (necessary so that the x-rays can actually be imaged), then they are essentially satellites, just not rocket launched, but as I pointed out in another thread, the pictures we have from high altitude balloons are just as much proof of a RE as the same type of pictures from rocket launched satellites.
This also brings up another question about x-ray astronomy. Do black holes exist if gravity doesn't?
