Our universe may have a twin that runs backward in time

If one can suggest an anti-universe running backwards in time from the big bang, then I would have thought that a real phase of the same Universe passing through a nexus immediately before the Big Bang, instead of a Big Nothing, or a Big Anti Backwards, would have been much more palatable as a model.

I was just saying to IG, something which belongs better here. IG, can we limit it to this thread please? (Slightly changed).
If you go 'backwards' from the BB, are you not in a perpetual 'cycle' of reverberation backwards and forwards between BH/BB's. Since your 'backwards' must be qualitatively the same as forwards (no broken glasses reforming) then it is a moot point as to whether there is any difference between a cyclic Universe (one direction in a circle) or a reverberating Universe (backwards and forwards). Both would come out of a complete mix up (singularity/nexus) and proceed indistinguishably towards the next.
