Galaxy red shifts go in steps?

Halton Arp was a controversial kinda guy. He had lots of problems with cosmology. He had some interesting and wrong ideas for sure.

But he also claimed that there was a periodicity in red shifts ...

Wiki tells us Arp's data were reviewed many times and found no such effect.

Perhaps there are ripple effects left over from the inflation era, that cause the expansion of space to occur in waves. (just a crazy conjecture).

Ohh, I like the crazy conjecture. A sort of baryon acoustic oscillations (BAO) like thing from the plasma but instead in the inflaton field itself.

That is quite good. Have a go-bag ready in case Stockholm calls.

Given the size of the surveys already done I would think that if redshift quantization were a thing the results would be stronger.

But there still is the question so more data is needed.

When the smart folks figure it out then we will know with some confidence one way or the other. Right now the consensus over the water cooler is that the redshift quantization is not favorably viewed but some new and interesting science may be on the way.

I wouldn't hold out much hope that redshift quantization will significantly derail the standard cosmological model as some of its fringe supporters hope. Right now the extraordinary level of data required to support the hypothesis is missing and none appear on the horizon.

That would be The Great Green Arkleseizure. Gotta watch out for that handkerchief part though.
