Astronomers have used the James Webb and Hubble space telescopes to confirm one of the most troubling conundrums in all of physics — that the universe appears to be expanding at bafflingly different speeds depending on where we look.
This problem, known as the Hubble Tension, has the potential to alter or even upend cosmology altogether. In 2019, measurements by the Hubble Space Telescope confirmed the puzzle was real; in 2023, even more precise measurements from the James Webb Space Telescope (JWST) cemented the discrepancy.
Now, a triple-check by both telescopes working together appears to have put the possibility of any measurement error to bed for good. The study, published February 6 in the Astrophysical Journal Letters, suggests that there may be something seriously wrong with our understanding of the universe.
I actually had no idea that an irregularly expanding universe was the conflicting theory.
From my armchair astrophysicist perspective, I just assumed it couldn’t be a perfect sphere due to the background radiation map.
Obviously scientific method and all, but this is super cool that for realisies it might change some minds.
The best moments in science are when we say, “wait, this doesn’t work.”
That’s exactly the opposite of how religion works and the reason why I firmly believe that there should be a clear separation between state and church.
People can believe in whatever delusions they want as long as they don’t force them on me.
But they always do, always, everywhere.
Even France which prides itself on it’s secularism is getting pounded. The US is delusional, “In God We Trust” ? Really, fuck that guy…
If you have church, it’s always church and state.
Wouldn’t that just be forcing your view of separation of church and state on everyone else?
/s
The sound of scientific discovery is less often “Eureka!” than “Huh, that’s funny…”
And sometimes “boink”
My science is growing
Solid Calvin and Hobbes reference
This was kind of the whole point of the JWST so it’s a good thing!
I just want our universe to be cyclic, heat death is depressing
Even though I won’t be there for it, somehow heat death makes me very sad.
Meh. Honestly I’m glad it will all end.
Everything is pointless and nothing matters. Eventually.
Everything is temporary, and meaning and beauty are in the eyes of the beholder. Your life isn’t “supposed” to be anything, so enjoy your brief opportunity to experience this crazy world that popped into existence before we did. And help others do the same, if you can.
If it makes you feel better, if ideas about multiple universes end up being real, it’s possible a sufficiently advanced species might be able to “hop” universes and escape heat death that way
Nice idea, did you borrow it from Liu Cixin ?
I have no idea what that is but the concept of the multiverse and possibly traveling between universes is an extremely old idea. This is just modernizing it to include the heat death of the universe
Yes, I mean that specific twist ! It’s present in a series of books by chinese author Liu Cixin called “the three-body problem” (I won’t say at what point to avoid spoiling it for you in case you’re into scifi and are interested in reading it)
Pretty cool idea if you ask me
Hmmm after jostling my memory a bit, it’s not exactly that. But it’s close, essentially the same idea
Ahhh my bad, googling him I don’t think I’ve heard of him or his works before (aside from announcements of three body problem getting a show), but it’s possible I picked up the idea through osmosis somewhere. Yea it’s so far off that it doesn’t really matter, but it definitely helps with that ultimate feeling of nihilism that thinking about the heat death can bring along.
On a cosmic scale, I find it kind of comforting that everything is eventually going to be gone. It makes it more important to enjoy one’s time in the now.
It could still be “gone” in the sense that nothing of this universe exists in its present state. Maybe it will collapse in on itself and a new Big Stretch will occur, and a new universe with new physical laws and new matter/energy will begin.
Maybe that’s how it’s always been. But whether it is finite or infinite, cyclical or linear, we will most certainly end, and that’s a good enough reason to live in the moment.
Damn, the beings running the ancestor sinulation must have downloaded a new patch.
Yesssss I yearn for new physics
The prospect of irregular and unpredictable physics gives me anxiety
With the universe is not being locally real, and now this… Oh man. Exciting times for sure.
Yes, discovery is awesome, and this is some crazy shit— it’s just that I prefer that the the rules that govern time and space make sense, lol.
It makes sense — we just don’t understand it yet 😀
