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.
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.
