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 feel the same. Even if myself, my kids, earth, even the human race as we know it won’t be there anymore, it’s kind of sad. Slow inevitable doom. Carpe diem I guess.

        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.

      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.

        The problem with this idea is that everything was already gone before the universe started, and here we are.

        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.

      Considering we don’t understand dark energy and dark matter. I hold hope that there are other possibilities.

      However, all hail the god of entropy. The one thing that dictates and impacts every moment of our existence

      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

          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.

        Not if all the universes began at the same moment.

      This doesn’t help at all but last I checked heat death was out and big freeze is in (spreading out to such a level that subatomic particles pull apart into basically nothingness).
