Galaxy Cluster blows minds, bends light.

[TriedandTested]

From my understanding: Some photons from the big bang (theory) are presumably still in existence, but spread out across the entire universe, so detecting them would be unlikely as most will have perished. Photons get absorbed when they hit something.

Someone on here probably knows far more about this than me, and I hope they correct me if I'm wrong.

But if these are at the edge of the universe their light has travelled all that way back to us and, I assume, the same distance in all other directions - if we're at the 'middle' and they are at the 'edge' where has all the other light/photons gone to - if photons are absorbed when they hit something then what would they have hit in the other direction (i.e in the direction of the edge!)?

Op updated, new source added, clarified!

It doesn't show 800 trillion stars but instead has the mass of about 800 trillion Suns! Facepalm from earlier tbh, quite a misunderstanding
