You’ve heard of the Big Bang. Now astronomers have discovered the Big Wheel – here’s why it’s significant

theconversation.com/youve-hear

"We previously thought galaxy disks form gradually over a long period: either through gas smoothly flowing into galaxies from surrounding space, or by merging with smaller galaxies.

Usually, rapid mergers between galaxies would disrupt the delicate spiral structures, turning them into more chaotic shapes. However, the Big Wheel managed to quickly grow to a surprisingly large size without losing its distinctive spiral form. This challenges long-held ideas about the growth of giant galaxies."

🚨 ESO analysis confirms that the INNA industrial megaproject would have a devastating and irreversible impact on the facilities at Paranal Observatory in #Chile.

➡️ Light #pollution would increase by at least 35% above ESO's Very Large Telescope, by a minimum of 5% above ESO’s Extremely Large Telescope and by at least 55% above the south site of the Cherenkov Telescope Array Observatory

➡️ Air turbulence would also increase, degrading seeing conditions by up to 40%

➡️ Vibrations from the project could seriously impair the functioning of the ELT and the VLT Interferometer, which are both extremely sensitive to micro-seismic noise.

➡️ Dust during construction is also problematic as it settles on the telescope mirrors and obstructs their view.

www.eso.orgNew ESO analysis confirms severe damage from industrial complex planned near ParanalAn in-depth technical analysis by the European Southern Observatory (ESO) has evaluated the impact of the INNA megaproject on the facilities at the Paranal Observatory, Chile — and the results are alarming. The analysis reveals that INNA would increase light pollution above the Very Large Telescope (VLT) by at least 35% and by more than 50% above the south site of the Cherenkov Telescope Array Observatory (CTAO-South). INNA would also increase air turbulence in the area, further degrading conditions for astronomical observations, while vibrations from the project could seriously impair the functioning of some of the astronomical facilities, like the Extremely Large Telescope (ELT), at the Paranal Observatory.

The lasers our Very Large Telescope (VLT) pierce the Milky Way… but what is that vertical glow just below? 🤔

That’s the zodiacal light: caused by dust grains in the Solar System, it's so faint that it’s only visible in the darkest skies, such as those of Chile’s Atacama Desert.

And the pristine night sky 🌌 in this region has always been intertwined with the culture and traditions of its indigenous people, discover how: eso.org/public/images/potw2511

There is a LOT of heavy lifting being done in this short article. I will attempt to summarize. 🙃

Scientist Says He Found Evidence Our Entire Universe Is Trapped Inside a Black Hole
uk.news.yahoo.com/scientist-sa

"Kansas State University associate professor of computer science Lior Shamir found that out of the 263 galaxies examined, two thirds of them rotated clockwise, while only a third rotated counterclockwise, as detailed in a paper published in the journal Monthly Notices of the Royal Astronomical Society.
[...]
"It is still not clear what causes this to happen, but there are two primary possible explanations," said Shamir in a statement. "One explanation is that the universe was born rotating. That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole."

The findings add credence to an existing, Russian doll-like theory called "Schwarzschild cosmology," which suggests that our galaxy is trapped within a black hole, which in turn is located inside another universe.
[...]
"I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole,"
[...]
As Space.com reports, this would imply that other observed black holes could be wormholes, otherwise known as Einstein-Rosen bridges, to other universes, which are unobservable to us due to the black holes trapping light within them."
