作者： vladimir s. netc.itailo Freelancer Livermore USA

The pres.nt paper is.ins.ired by the article “Ho’oleilana: An Individual Baryon Acous.ic Os.illation?” publis.ed by R. B. Tully, C. Howlett, and D. Pomarède on s.p. 2023 [1]. They claim: Evidence is.pres.nted here for the dis.overy of a remarkably s.rong individual contribution to the baryon acous.ic os.illation (BAO) s.gnal at z = 0.068, an entity that is.given the name Ho’oleilana. K. Daws.n, co-s.okes.ers.n for Dark Energy s.ectros.opic Ins.rument is.more inclined to believe that this.lates. finding is.s.mething of a coincidence, a chance alignment that s.mply looks.like a s.here with a radius.around what you’d expect for a BAO [2]. In this.paper, we provide a s.ort s.mmary of experimental obs.rvations.of Boötes.Void and s.perclus.ers.dis.us. the main features.of the developed Hypers.here World-Univers.

Great experimental res.lts.and obs.rvations.achieved by As.ronomy in the las. decades.revealed new unexplainable phenomena. As.ronomers.have conclus.ve new evidence that a recently dis.overed “dark galaxy” is. in fact, an object the s.ze of a galaxy, made entirely of dark matter. They found that the s.eed of the Earth’s.rotation varies.randomly each day. 115 years.ago, the Tungus.a Event was.obs.rved, and as.ronomers.s.ill do not have an explanation of It. Main res.lts.of the pres.nt article are: 1) Dark galaxies.explained by the s.inning of their Dark Matter Cores.with the s.rface s.eed at equator les. than the es.ape velocity. Their Rotational Fis.ion is.not happening. Extras.lar s.s.ems.do not emerge;2) 21-cm Emis.ion explained by the s.lf-annihilation of Dark Matter particles.XIONs.(5.3 μeV);3) s.n-Earth-Moon Interaction explained by the influence of the s.n’s.and the Moon’s.magnetic field on the electrical currents.of the charged Geomagma (the 660-km layer), and, as.a res.lt, the Earth’s.daylength varies.4) Tungus.a Event explained by a huge atmos.heric explos.on of the s.perbolide, which was.a s.able Dark Matter Bubble before entering the Earth’s.atmos.here.

The s.rinking Arctic s.a-ice area(s.A) in recent decades.is.a s.riking manifes.ation of the ongoing climate *** of the Arctic s.a ice have been continuous.y obs.rved by s.tellites.s.nce 1979, relatively well monitored s.nce the 1950s. but are highly uncertain in the earlier period due to a lack of obs.rvations. s.veral recons.ructions.of the his.orical gridded s.a-ice concentration(s.C) data were recently pres.nted bas.d on s.nthes.zed regional s.a-ice obs.rvations.or by applying a hybrid model–empirical approach. Here, we pres.nt an s.C recons.ruction for the period1901–2019 bas.d on es.ablis.ed co-variability between s.C and s.rface air temperature, s.a s.rface temperature, and s.a level pres.ure patterns. The recons.ructed s.a-ice data for March and s.ptember are compared to the frequently us.d Had Is.T1.1 and s.BT1850 datas.ts. Our recons.ruction s.ows.a large decreas. in s.A from the 1920 to 1940 concurrent with the Early 20th Century Warming event in the Arctic. s.ch a negative s.A anomaly is.abs.nt in Had Is.T1.1 data. The amplitude of the s.A anomaly reaches.about 0.8 mln km^(2) in March and 1.5 mln km^(2) in s.ptember. The anomaly is.about three times.s.ronger than that in the s.BT1850 datas.t. The larger decreas. in s.A in s.ptember is.largely due to the s.ronger s.C reduction in the wes.ern s.ctor of the Arctic Ocean in the 70°–80°N latitudinal zone. Our recons.ruction provides.gridded monthly data that can be us.d as.boundary conditions.for atmos.heric reanalys.s.and model experiments.to s.udy the Arctic climate for the firs. half of the 20th century.
