Andiamo alla scoperta di concetti cosmologici come big crunch e big bounce, due modelli sul destino dell'universo non ancora verificati, insieme con Newton Pitagorico e uno spaesato Paperino!
🌌 Scientists Befuddled by Impossible Galaxy Seen by James Webb
— Futurism
"As detailed in a new study published in the journal Nature, the so-called quiescent galaxy, ZF-UDS-7329, contains more stars than the Milky Way — despite forming just 800 million years after the Big Bang. This suggests that it somehow came together without the gravitational pull of dark matter, which shouldn't be possible."
#Simulations that track the formation of #smallgalaxies after the #BigBang and include, for the first time, previously neglected interactions between #gas and #darkmatter show that the galaxies created are very tiny, much brighter, and form more quickly than they do in typical simulations that don't take these interactions into account.
It's great to see that was at least one other talk (aside from mine) at #37c3 that showed a timeline from the #bigbang to today. But #MajaGöpel obviously mostly talked about the past 50000 years, while I talked mostly about the first 10 billion. 🙂
Instead of a single Big Bang that brought the universe into existence billions of years ago, cosmologists are starting to suspect there may have been a second transformative event that could explain the vast abundance of dark matter in the universe.
