So we have a contradiction to solve
Fully formed galaxies found too close in time to the big bang. We can see the galaxy, but we can't see the big bang. One is obvious, other other isn't. Here is another contradiction:
High redshift object found close to low redshift source
Objects with high- and low-redshift mixing and mingling. Maybe we are seeing objects made of different types of matter with different emission bands? Maybe there is more exotic matter further away?
I've spent my ideas here. What am I, a physicist?!?
