That only works if radiation density and expansion are connected. General Relativity says that they aren't.

- mnky9800n 2y agoHow does general relativity say that?
- btilly 2y agoThe term for the stress-energy tensor has the wrong impact on expansion for a simple relationship of any kind. You can rescue it with pseudo-tensors, but then you force the existence of a preferred reference frame. Which undermines the principles of GR. Some still argue for that. Others don't.
