How can you generate separate beams of neutrinos and antineutrinos when you don't even know whether they're different from one-another in the first place?

Last but not least, a new measurement of the Hubble Constant is obtained by analyzing the geometrical properties of Ho'oleilana: 76.9 (+8.2)(-4.8) km/s /Mpc

This value is consistent with other direct local probes, and further exacerbates the "Hubble tension" in the ΛCDM model.

By contrast, the discovery of Ho'oleilana represents the 1st direct evidence of a BAO, as an individual entity and a new confirmation of the standard model of cosmology.

A discovery made 53 years after the prediction - that's more time elapsed than for e.g. Higgs and his boson!

Acoustic waves generated in the hot plasma of the early universe became imprinted in baryon fluctuations. The prediction was made in 1970 by Jim Peebles and others. Indirect evidence of the BAO phenomenom came in 2005 by observing a peak in the pair-wise separations of galaxies.

A spherical shell-like structure 1 billion light-years in diameter named Ho’oleilana is discovered in the distribution of relatively nearby galaxies. We posit this is the 1st observation of an individual Baryon Acoustic Oscillation (BAO).
