You're absolutely correct. Thanks. I had the Angstroms right, and screwed up in the scientific notation for meters. I've fixed it up above.

PS. Added in edit. I don't know if this makes me more or less stupid, but I did these same numbers correctly just a few days ago, in this post.

This part is the energy of the 'new photon' about to be re-emitted.
This is a bit difficult for an electron that is around half a meter or more from the nearest other electron/ion/atom. The plasma in between galaxies is very thin.

Transferral of energy or momentum to other particles will take an long time, on these kinds of scales. What you need to do is quantify this alleged transferal. This has been the consistent problem all along; there has never been any quantified energy momentum analysis, except that one which introduced the invalid notion of variable electron rest mass.

I will attempt a first stab at a estimating the of transferral of energy and momentum to other particles shortly
