I knew about adverse possession but a squatter was just trespassing until that kicked in. Apparently I have to get them written notice and 30 days to get gone in my state.
I wonder why it doesn’t decrease the number of rental home vacancies? Odd.
Youtuber Anton Petrov a.k.a. WhatDaMath stands at the frontline of scientific research: he has already produced a video on Ho'oleilana, just 3 days after the publication of its discovery!
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).
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.
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!
Ho'oleilana was found unexpectedly in the distribution of galaxies of the Cosmicflows-4 Catalog, within its SDSS PV "Peculiar Velocities" subsample of early-type galaxies, derived from fundamental plane measurements.
The cosmography of Ho'oleilana is pretty amazing: its shell includes some of the largest known structures of the universe: the Sloan Great Wall, CfA Great Wall, Hercules Supercluster, Corona-Borealis Supercluster... At its core is the Boötes Supercluster.
A video visualization of the cosmography of Ho'oleilana is part of the paper. Major components in proximity to the shell are highlighted and identified by name. The historic Boötes Void lies interior to the shell structure.
A major aspect of the study presented in this paper is the analysis conducted by Cullan Howlett to understand the significance of this discovery against a physical BAO model, using in particular mock galaxy catalogs with and without BAO features.
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.
Ka’iu and Larry Kimura named other astronomical objects before: the interstellar asteroid ʻOumuamua, the imaged black hole Pōwehi (M87*), and others as part of the "A Hua He Inoa" program: Leleākūhonua an extreme transneptunian, Pōniuāʻena a quasar, ...

‘Bubble’ of galaxies discovery may revolutionise cosmology
Cullan Howlett on the new measurement of the Hubble constant inferred from Ho'oleilana, in the press release by the University of Queensland: “We’re now a step closer to a great change in the field of cosmology, where the whole model of the universe might need re-evaluating.”
