I only propose it as an alternative to expansion and big bang theory as it confuses me how we still hold onto this with more and more evidence stacking up against it. Cosmologists seem to be much more content adding so many complicated adaptions to BBT and the expanding universe to explain away more and more observations and measurements that contradict it. ☹️

I read recently that the CCACP has measured the mean temperature of the universe to be actually getting much hotter over the last 10 billion years, not colder as BBT / expansions suggests. I wonder what new radical adaption will be added to this dated and failed theory now 🙄..

The so called 'crisys in cosmology' could perhaps be solved if we let go of expansion and work on new models of the universe.

As far as 'open' or 'closed is not quite what im on about, curvature would not necesarilly lead to 'closed' if you consider spacetime finite. I only suggest that spacetimes natural curve is very slight, and in the opposite direction to curvature caused by massive objects. It would explain a lot of things allready observed over the last 100 years and may be a new way to understand hubbles constant thinking of it as a curvature and not an expansion/ acellaration , in general relativity (gravity) curvature of spacetime has much the same effect as acceleration.. The expansion of the universe may just be a much bigger and backwards version of how gravity was viewed as a 'force' before general relativity .......
