Apparent evidence for Hawking points in the CMB Sky ★
Posted by Saúl Morales Rodriguéz in category: cosmology
ABSTRACT. This paper presents strong observational evidence of numerous previously unobserved anomalous circular spots, of significantly raised temperature, in the cosmic microwave background sky. The spots have angular radii between 0.03 and 0.04 rad (i.e. angular diameters between about 3° and 4°). There is a clear cut-off at that size, indicating that each anomalous spot would have originated from a highly energetic point-like source, located at the end of inflation – or else point-like at the conformally expanded Big Bang, if it is considered that there was no inflationary phase. The significant presence of these anomalous spots, was initially noticed in the Planck 70 GHz satellite data by comparison with 1000 standard simulations, and then confirmed by extending the comparison to 10 000 simulations. Such anomalous points were then found at precisely the same locations in the WMAP (Wilkinson Microwave Anisotropy Probe) data, their significance was confirmed by comparison with 1000 WMAP simulations. Planck and WMAP have very different noise properties and it seems exceedingly unlikely that the observed presence of anomalous points in the same directions on both maps may come entirely from the noise. Subsequently, further confirmation was found in the Planck data by comparison with 1000 FFP8.1 MC simulations (with l ≤ 1500). The existence of such anomalous regions, resulting from point-like sources at the conformally stretched-out big bang, is a predicted consequence of conformal cyclic cosmology, these sources being the Hawking points of the theory, resulting from the Hawking radiation from supermassive black holes in a cosmic aeon prior to our own.

Roger Penrose, Reinhard Genzel and Andrea Ghez bag the Nobel Prize for Physics
Posted by Kelvin Dafiaghor in categories: cosmology, education, physics
Congratulations from Ogba Educational Clinic.
The 2020 Nobel Prize for Physics has been awarded to Roger Penrose, Reinhard Genzel and Andrea Ghez for their work on black holes.
The prize is worth 10 million Swedish krona (about $1.1 million) and half goes to Penrose, with Genzel and Ghez sharing the other half of the prize.

Astronomers Solve Mystery of a Galaxy Containing 99.99% Dark Matter
Posted by Genevieve Klien in category: cosmology
The mystery of a galaxy that shouldn’t have existed could now have a solution. Dragonfly 44, a faint galaxy that was found in 2016 to consist of 99.99 percent dark matter, has been closely re-examined, revealing a lower and more normal proportion of dark matter.
This would mean that we don’t have to revise our models of galaxy formation to try to figure out how they could have produced such an extreme outlier — everything is behaving completely normally, the researchers said.
“Dragonfly 44 (DF44) has been an anomaly all these years that could not be explained with the existing galaxy formation models,” said astronomer Teymoor Saifollahi of the Kapteyn Astronomical Institute in the Netherlands.
Telescopes have captured the rare light flash from a dying star as it was ripped apart by a supermassive black hole.

Magnetic Levitation of Gas Clouds Near Black Holes Considered as Magnets
Posted by Quinn Sena in category: cosmology
Magnetic fields are far stronger and more important than gravity in forming stars and galaxies. Contrary to black hole propaganda, magnetic fields increase in strength the nearer to the center. There just is not a gravity center of mass to earth based reality in outer space.

Black hole “crystals” as seeds of structure formation in the early Universe
Posted by Quinn Sena in categories: cosmology, existential risks, particle physics
Circa 1994
It is generally accepted that structure formed in the matter dominated Universe, for obvious reasons. In this paper, we would like to suggest an alternate theory: that structure could have formed in the radiation dominated Universe if it was “protected” from destruction. This protection is envisioned as a “crystal”, of sorts, made up of primordial black holes (PBH’s), which form a cavitation into which any matter particles in the nucleosynthesis period of the Universe (around 100 seconds after the Big Bang) could have taken refuge. A sort of oasis in a sea of radiation. Such a scenario could solve several problems in cosmology, namely: how matter got a foot-hold over anti-matter in the Universe; the structure/galaxy formation problem; and possibly suggest ideas on the gamma-ray count and distribution.

The Largest Black Holes in the Universe Formed in a Snap — Then Stopped
Posted by Genevieve Klien in category: cosmology
The biggest, oldest black holes in the universe shouldn’t technically exist. A new study provides fresh evidence for the weird, “direct collapse” process that may have made them.

Another universe existed before ours – and energy from it is coming out of black holes, says Nobel Prize winner

Sir Roger Penrose also claims that another universe will exist after this one.
