But we could see the relation between gravitation and radiation in other observations, too, since we could measure x-rays in the center of galaxies.
To say 'time is time' is not in line with relativity, what made time an aspect of spacetime - as well as space.

Special theory of relativity says about gravitational bending of light, near Sun, stars etc., large masses. It is ok. Bending of light in strong gravitation is ok. GTR says space-time continuum, and space it self is curved. That confuses every one. In Dynamic Universe model of Cosmology, GTR is not required. No Bigbang singularity. It is based on non -uniform mass densities and mass about mass rotations. Uniform mass distribution of GTR is one of the main reasons of Bigbang singularity.
We can see clearly, no part of sky is an exact replica of another, for example.
I hope we are not going off topic. You can see in some other ATM threads, details about this Dynamic universe model.
Here what I am trying to say is that Bigbang is not required for producing CMB. Stars and other astronomical bodies are sufficient to produce CMB.
