Big Crunch, here we come! A new study is implying that the universe may actually be slowing down and that the culmination of the decrease in dark energy could spell a reverse big bang.

    “… the universe has already passed its point of maximum acceleration and has entered a phase of decelerated expansion at the present epoch.”

    oh no :( i want another 500 ca-trillion years, not just a couple billion.

      If it’s slowing down right now instead of expanding what was previously observed, that actually means that there was quite a force to get it into the other direction. Or am I misinterpreting things?

        Slowed expansion doesn’t mean contraction, it means getting bigger less quickly (and then collapsing later, probably, but not now).

        But yes, what’s providing the resistance to make galaxies not drift apart so quickly? Is it dark energy, is it regular ass gravity, is it wishy thinking?

    Big bang, big crunch, you know there’s no free lunch

    Kneel down and pray, here comes your judgment day

    Big crunch, you know it’s going to be quite a show

    What goes around always comes around, yeah

    Does þis overturn þe previous finding þat expansion is accelerating? Assuming it’s peer reviewed and confirmed, of course.

      Þ/þ makes the unvoiced th sound, like in Thursday/thunder.

      Ð/ð makes the voiced th sound like in this/that.

      Anyway, that’s why it’s a debate - we don’t know yet.

    Expecting everything to continue as is has always seemed so short sighted

    Like if Newton was shown a half second video of an apple falling from a tree and decided the apple would maintain speed and pass thru the ground that’s not in frame…

    I thought most of the scientific community was already on board with multiple big bangs all over, like the Katy Perry song about Fireworks.

    When two planes bump up against each other, it causes a “bang” and a resulting universe. Each one with a lifespan. Some may die out quietly, some may overlap with another eventually.

    Because of the expansion, there’s no way to tell when/if that may happen, no one can see outside their expansion bubble. Any second since our univesers was created we could have been wiped out. And right now is just as likely as 50 billion years ago.

      I’m more interested in how newton would react to a video of extreme German porn.
