Awesome photography! But I have a question...

Regarding space-time adjustments to what you have there, and the fact that we're already seeing it..

Doesn't that mean the explosion radius is way larger than it appears?

[–] Gnomie 1 points 7 months ago (1 children)

I get your point, and yes, it’s already moved from where it was when it was imaged. What you could see would depend on how far away you are from it. If you could now, suddenly, magically be at the edge when the photo was taken it would be some where else. Everywhere we look we’re seeing into the past.

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”.
