I always wonder if light traveled billions of years to get here wouldn’t it be possible that it got distorted along the way? What if all these galaxies are just a sort of a typical pattern of what light looks like after an unfathomably long journey through space/gravity/time/etc? It could be likely that what we’re seeing is no indication of what was ever actually out there.


It does. One effect of light passing through gravitational wells is gravitational lensing.

There is also Redshift.
