New on Formulon:
How James Webb and latest data are shaking up our ideas about the Universe 🌌✨
From surprising early galaxies to Hubble tension & cosmic structure anomalies — we’re entering a new era of cosmology.
Is ΛCDM in trouble, or just evolving?

Könnt ihr das erklären:

"But how come Penrose’s theorems forbid out such outcomes? It’s all down to a rule called the quantum exclusion principle..."
Kann mir kaum vorstellen, dass Penrose das Pauli-Prinzip nicht kannte.

This is a highly interesting study! 🧐
https://www.mpifr-bonn.mpg.de/pressreleases/2024/10The amplitude of the dipole is not as high as in the papers by Singal, Secrest, Schwarz et al.. curious to follow-up on why this turns out to be the case! (deeper survey, different sampling on the sky, etc..)

Die Dunkle Energie bewirkt, dass sich unser Universum beschleunigt ausdehnt, gilt aber selbst als konstant.

[Перевод] Исследователи с DESI составили самую большую трёхмерную карту нашей Вселенной
С помощью 5 000 крошечных роботов в телескопе, расположенном на вершине горы, исследователи могут заглянуть на 11 миллиардов лет в прошлое. Свет от далёких космических объектов только сейчас достигает спектроскопического прибора Dark Energy Spectroscopic Instrument (DESI), позволяя нам составить карту космоса, каким он был в юности, и проследить его развитие до того, что мы видим сегодня. Понимание того, как развивалась наша Вселенная, связано с тем, как она закончится, и с одной из самых больших загадок в физике: тёмной энергией , неизвестным ингредиентом, заставляющим нашу Вселенную расширяться всё быстрее и быстрее. Чтобы изучить влияние тёмной энергии за последние 11 миллиардов лет, в DESI создали самую большую трёхмерную карту нашего космоса из когда-либо созданных, с самыми точными измерениями на сегодняшний день. Впервые учёные измерили историю расширения молодой Вселенной с точностью более 1 %, что даёт нам лучшее представление о том, как развивалась Вселенная.

"…age of our universe…estimated at 13.797B years using #LambdaCDM concordance model…
However, many scientists have been puzzled by the existence of stars like the Methuselah that appear to be older than the estimated age of our universe and…early galaxies in an advanced state of evolution made possible by #Webb…existing a mere 300M years or so after the Big Bang, appear to have a level of maturity and mass typically associated with billions of years of cosmic evolution.
