Dark Energy Debate Reignites As Study Finds Universe's Expansion Is Actually Slowing : science

Fucks sake, just when we were starting to get people to move to Linux!

[-] artifex@piefed.social 8 points 11 months ago

I think Year of the Linux Desktop was always supposed to be a harbinger of the world’s end.

"... 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.

[-] anugeshtu@lemmy.world 1 points 11 months ago

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?

[-] ol_capt_joe@piefed.ee 9 points 11 months ago

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?

[-] SoleInvictus@lemmy.blahaj.zone 7 points 11 months ago

Definitely the ass gravity.

[-] anugeshtu@lemmy.world 2 points 11 months ago

Isn't expansion comparable to speed instead of acceleration? If the universe is expanding, i.e., already spreading in all kinds of directions constantly, wouldn't slower expansion mean deceleration? But I guess you meant the same with "eventual collapse later, but probably not now".

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

Oh you absolute scholar.

I clicked on every link trying to find the actual paper.

[-] Smaagi@lemmy.world 5 points 11 months ago

This just enforces my old thought that we're living in another universes black hole, it's just getting less matter now.

Contraction incoming or nah?

Might just stop for all we know. Then we have to rename it the big splat.

It’s pending all its cycles simulating our consciousness simulations, instead of rendering further out.

[-] bookmeat@lemmynsfw.com 1 points 11 months ago

Hear me out. What if the expansion is a wave. We expand and then we contact and then we expand again. Who knows whether our current circumstances are linear?

[-] the_crotch@sh.itjust.works 1 points 11 months ago

We're going to need another few billion years worth of data

[+] givesomefucks@lemmy.world -9 points 11 months ago

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.

[-] krooklochurm@lemmy.ca 3 points 11 months ago

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

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

[-] ol_capt_joe@piefed.ee 7 points 11 months ago

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.

[-] Sxan@piefed.zip 2 points 11 months ago

Thorn had completely replaced eth by þe Middle English period. It's arbitrary usage to begin wiþ.

[-] rumschlumpel@feddit.org 1 points 11 months ago

That's only how it works in IPA, these letters are/were used in several languages and none consistently used thorn for one sound and eth for a different sound.

[-] Zeoic@lemmy.world -3 points 11 months ago

Wait, whats different between the th in thursday and in this? They make the same sound

[-] SlothMama@lemmy.world 4 points 11 months ago

They absolutely do not

[-] Zeoic@lemmy.world -2 points 11 months ago

Well that must be one hell of a regional difference, because they most certainly do.

[-] SlothMama@lemmy.world 2 points 11 months ago

It's difficult to explain this, but you're wrong, there is no regional dialect that would pronounce the word this as this, because it is awkward.

Both are interdental fricatives, but this is always done with a voiced dental fricative, a voiceless would be the way people pronounce thistle. Now try to say this place but say this without the le on thistle.

I'm on mobile and can't type out the IPA symbols, but I did take linguistics classes so I know the difference between the two phones, whereas you seem to equate the phones with their orthography.

[-] Zeoic@lemmy.world 1 points 11 months ago

I really dont know what to say lol. This sounds exactly the same to thistle to me. I went and researched the voiced and voiceless th, but none of the explanations really tracked with how I say th and how i hear it said around me. To me, "voiced th" is simply me not whispering.

[-] rumschlumpel@feddit.org 2 points 11 months ago

Check the IPA, they do not. Incidentally, the phonetic alphabet is pretty much the only writing system that ever used thorn and eth consistently for different sounds.

[-] the_crotch@sh.itjust.works 1 points 11 months ago

Imagine pronouncing "this" like the first syllable of "thistle". There's more emphasis on the "th" sound than there is when you say "this"
