The Dark Energy Spectroscopic Instrument (DESI) has released Data Release 1 (DR1), presenting the largest and most detailed 3D map of the universe to date. This dataset encompasses information on 18.7 million celestial objects, including approximately 4 million stars, 13.1 million galaxies, and 1.6 million quasars, extending back 11...

Fun fact: If dark energy density has indeed slowed down, then that would potentially fix the Hubble tension. Distance ladder measurements would have overestimated Hubble constant while assuming constant DE density according to the existing model 😮

Guess who’s not a fan of data ownership? 😅 When #Zuckerberg gives zero stars, you know the @datamaskwallet app is keeping your data safe from the big tech giants' grasp. 🚫📊 #DataPrivacy #BigTechNemesis art and creative by @Matteo_Frog

The disk in the middle es the Milky Way, right? (outside perspective of what wee see from Earth).

If DESI’s findings indicate that dark energy is evolving, could that be indirect evidence in favor of the black hole coupling hypothesis? A dynamic dark energy component aligns with the idea that black holes might be acting as its source, changing in strength over time rather than being a fixed vacuum energy.

Thats looks like an impossible viewpoint, you have xyt coordinate data from an origin How do i see the points at the same t as the origin. I would see my own unique xyt distribution as i rotate around the datas xyz at time t origin point.

🚨NEW: Elon Musk explains the reason behind the SpaceX and xAI merger. "In order to understand the universe, you must explore the universe. That's the motivation behind the combination of SpaceX and xAI is to accelerate humanity's future in understanding the universe and extending the light of consciousness to the stars. So in the grand scheme of things, when you look at how much energy Earth is actually using for civilization, we're only right now using, call it roughly 1% of the potential energy of Earth. And if we wanted to use even a millionth of the sun's energy, that would be roughly a million times more energy than civilization currently uses. The only way to access that energy, the energy of the sun is to extend beyond Earth. Earth is really a tiny, tiny dust Mote in a vast darkness. The sun is 99.8% of all mass in the solar system, so you have to expand beyond the tiny dust mode that is earth to make any significant dent in using the sun's energy like says, you'd have to expand roughly a million times just to get to 1,000,000th of our sun's energy, and then going beyond that, exploring extending to the Galaxy. So the the next step beyond Earth data centers is our Earth orbital data centers, and we'll be launching with SpaceX orbital data centers at the 100 to 200 gigawatt per year level, not cumulative, I mean, per year. And ultimately, we see a path to maybe launching as much as a terawatt per year of compute from Earth."

Another Galaxy Without Dark Matter Dark matter is thought to account for about 85% of the Universe's total mass, yet there are galaxies that stubbornly refuse to conform to this rule. A team of astronomers led by researchers from Yale, using the Keck Observatory, has discovered a third such galaxy: the faint dwarf DF9, which appears to lack invisible mass entirely. The concept of dark matter emerged in the 1970s, when Vera Rubin first convincingly demonstrated that galaxies are held together by some form of invisible mass. Since then, a wealth of indirect evidence—such as galactic halos and gravitational lensing—has accumulated. This makes the exceptions all the more intriguing. DF9 sits alongside two other similarly "empty" galaxies—DF2 and DF4—as part of an elongated chain of seven galaxies located 45 million light-years away; all of them appear to have originated from a single event. How was this determined? By analyzing stellar motion, the team estimated DF9's mass at approximately 100 million solar masses—a figure that matches the combined mass of its visible stars, gas, and dust. Had dark matter been present, the total mass would have been roughly a hundred times greater. The necessary precision was achieved using the KCWI spectrograph on the Keck telescope, an instrument specifically designed to detect extremely faint light sources. It appears that DF2, DF4, and DF9 formed during a high-speed galactic collision that stripped gas clouds away from their dark matter halos, allowing the new galaxies to coalesce from ordinary matter alone. Lead author Michael Keim notes that a chain of dark-matter-free galaxies has never been observed before. His supervisor, Pieter van Dokkum, adds that this provides compelling evidence that dark matter is a genuine physical substance rather than merely a "correction" to the theory of gravity.
