Just thought of another point …
If the effects of something exist and are real, can we infer that its causes are therefore real, also ?
Ie: the cause of comic expansion/acceleration is 'dark energy', therefore we can infer that dark energy is real, because expansion is real (measurable).
Cheers
PS: I think the BAO measurement in this case was achieved at a highest redshift of z = 0.6. I think the best achieved prior to this was z=0.2 and z=0.35 (?)
