I think I agree !

The expectation that all galaxies should have the same handedness is really what's in question here. And if they do display some bias, does that really mean anything in the overall scheme of something as big and complex as the universe ? Does it really mean there is a preferred frame of reference ?

As an example of nature not measuring up to our 'expectations': take retrograde orbital motions of moons (Like Triton). Some of the exo-planets also have retrograde orbits as well. Was there ever an expectation that this shouldn't occur ? (I think 'yes').

Is the 'cosmic accident', (which is something like one in a million), sufficient to draw an inference that this is a 'non-accident', or is it just a matter of sample size bias ?

I haven't read their paper yet … thanks for that, Carl.

Good to see the Cosmological Principle being queried though … (I don't think this'll ever stop .. which is a good thing).

Cheers
