You missed my point altogether. It doesn’t matter if the source of the event moved at all or not, I’m talking about the shockwave through the universe.
Once we can actually see the radius of a supernova explosion, well that radius is long ago in the past, and whatever dangerous gamma rays or neutrinos or whatever have probably long ago passed us.

Time dilation yo.
I got your point; I think you just argued my point. Nothing we image is as it “is” but rather as it “was”.
