Are observations of the CMB and JWST early galaxies compatible?
When detailed maps of the Cosmic Microwave Background were obtained it supposedly confirmed our theories about the universe, yet the JWST's recent observations of colliding galaxies 0.3BY after the big bang refutes them.
Are those observations compatible with each other? (okay, one is about whether the universe came from a singularity, the other is about the timing and order of galaxy formation but still).
Would you expect the CMB to look different if galaxies were forming much earlier than anticipated? Would it make a difference? Or would it look the same regardless?
Does it suggest that physics may not be invariant across time, and that the laws that govern galaxy formation were different back then?
And if that's the case, then when we peer at distant galaxies we are not merely looking backward in time, but backward in the evolution of physics too. That would be cool.
I guess this might make that whole awkward dark matter/energy problem disappear, no?
Just my unqualified ramblings, but it's interesting to ponder, no?
