the fate of the universe

voting multiverse cuz it seems like the most fun. also Moorcock.

whatever happens, the universe will probably have ended before the results of this poll can be revealed. :(

multiverse - cos I think it's the view of String/M-Theory, which is the most advanced universal model so far supposedly.

which one of these is most depressing?

big freeze is

It's a whimper, right? Sheesh.

big rip sounds most fun

Or the universe has always existed and will continue to do so, stretching out into infinity. Is this an option or should I go back to the zen assholes thread?

chose multiverse btw.

Big Freeze! These all sound like wrestlers btw.

voting multiverse cuz it seems like the most fun. also, more cock.

sliders

big bounce. eternal return, motherfuckers.

multiverse doesn't mean this individual universe won't wear thin, tho?

if they stopped pointing all of our most powerful telescopes into the past we would have some advance warning of this, tbh

whatever happens, the universe will probably have ended before the results of this poll can be revealed. :(

You think the universe will end within the next 8000 years?!

from a strictly personal viewpoint it's damned near a certainty

I think the universe will end before they are able to recover the data from this thread which will probably be long-lost in 8000 years

on the contrary, in 8000 years ilxors will be a ruling elite imo

Big bounce.

I theorised this as a joke during a particularly boring live sketching class at art school, and was gutted to find out that physicists had got there before I had.

When I was a little, little girl I used to have nightmares about the heat death of the universe due to physics stories my dad used to tell me at bedtime. (I had no concept of time, didn't realise it was due to happen in millions of years rather than, say, next week.) So I'm definitely voting against that one.

not a buddhist I see

i don't believe in the prolonged suffering of dumb beasts tbh

Nice to see a fresh theory, but it hasn't been peer reviewed yet and doesn't explain everything.

http://www.technologyreview.com/blog/arxiv/25492/

A "galactic lens" has revealed that the Universe will probably expand forever.

None of these can be determined from available evidence, so one's choice is essentially a matter of taste. The Big Bounce is perhaps the most aesthetically pleasing to me.

The main difficulty with theories that require a unique beginning to and a irreversible end of the universe is that the mind revolts at the idea that everything came from nothing and then reverts to nothing, where time does not exist at all, then suddenly begins, then stops and never starts again. It seems both illogical and intolerable (but then, we are earthborn creatures who require time and matter to exist).

The Big Bounce does not exactly solve these problems, so much as postpone their relevance infinitely. This idea is just as illogical as any other solution, but the flaw there is less viscerally repellent, since it is so infinitely remote as to become infinitely nebulous. It appeals to the Scarlett O'Hara in me: "Fiddle-dee-dee. I'll think about that tommorrow."

been on a multiverse kick lately

Quite taken by Big Bounce.

big fart

I absolutely love all this stuff. Should've been an astrophysicist, except I'm a bit crap at maths.

Poplawski says the origin of the arrow of time comes from the asymmetry of the flow of matter into the black hole from the mother universe. “The arrow of cosmic time of a universe inside a black hole would then be fixed by the time-asymmetric collapse of matter through the event horizon,” he says.

*stares at lava lamp*

'endless expansion' theory depresses me so much. i've always been a big crunch kind of guy, go out with a bang imo.

http://www.sciencecodex.com/first_direct_evidence_of_cosmic_inflation-129836

Pretty sure all of those options are also apocalyptic scenarios from various religions around the world. "Big freeze" seems like the most Zen thing ever, all matter breaking down, the laws of physics dissipating, all everything ever combining into one eternal universe-size waveform. In a way, it resembles the pre-cosmic egg of undifferentiated matter from Hindu traditions.

Also i thought the red-blue shift/doppler effect was the 'first direct evidence'.

That was evidence for the Big Bang. I gather 'cosmic inflation' has to do with the nature of the Big Bang, what it was like in the first trillion-trillion-trillionths of a second. Here's wikipedia:

In physical cosmology, cosmic inflation, cosmological inflation, or just inflation is the expansion of space in the early universe at a rate much faster than the speed of light. The inflationary epoch lasted from 10−36 seconds after the Big Bang to sometime between 10−33 and 10−32 seconds. Following the inflationary period, the universe continued to expand, but at a slower rate.

Poplawski says the origin of the arrow of time comes from the asymmetry of the flow of matter into the black hole from the mother universe. “The arrow of cosmic time of a universe inside a black hole would then be fixed by the time-asymmetric collapse of matter through the event horizon,” he says.

Say this were true: what would theoretically happen to time if the Big Crunch would occur? If the universe recollapses, will time - or our perception of time - be reversed too? Or would the 'arrow of time' continue as it is doing right now?

(asking for a friend)

is it urgent

I don't understand what Poplawski is saying.

but

Stephen Hawking thought about this and initially thought time would reverse in a collapsing Universe, but then complications were pointed out to him and he rejected the idea.

complications hardly seems a sufficient description tbf

lol deems

I ask more because of what Poplawski is quoted saying in that link before the posted quote:

Incidentally, this approach also suggests a solution to another of the great problems of cosmology: why time seems to flow in one direction but not in the other, even though the laws of physics are time symmetric.

Would time's arrow follow the same path it has been doing, or would a crunch 'reverse' it?

Do you remember the specific complications that were pointed out, abanana?

Or have a link to where I can read more abt Hawkins on this subject?

seems like a "superman spinning Earth backwards to reverse time" idea to me, but physics is complicated.

It is gone over in the errol morris doc. http://youtu.be/QjFynyihXuY?t=1h4m00s

I see Hawking here dismissing the idea of reverse time: https://suite.io/arash-farzaneh/4cjx2c7

Xp thanks!

The universe is a shit from Gods ass

Well, then, it is some pretty amazing shit.
