I’m no scientist, but...
Here on Earth a shock wave results when a force pushes air ahead of it. It dissipates over distance. In space, there is no air to push. So it must be the matter from the CMA, meeting no resistance on its way that is stripping the atmosphere from that blue planet. But wouldn’t the stream widen over distance, having the effect of dissipating the force?
I get a headache when I think on these things!
“But wouldn’t the stream widen over distance, having the effect of dissipating the force?”
Correct, but you have to remember that the ejected matter starts out as a humongously large mass travelling at a million miles an hour with no resistance in front of it................
