Universe Closer To Heat Death Than Once Thought

Soulskill posted more than 4 years ago | from the we're-doomed dept.

Science 237

TapeCutter writes "In a paper soon to be published (PDF) in the Astrophysical Journal, Australian researchers have estimated the entropy of the universe is about 30 times higher than previous estimates. According to their research, super-massive black holes 'are the largest contributor to the entropy of the observable universe, contributing at least an order of magnitude more entropy than previously estimated.' For those of us who like their science in the form of a car analogy, Dr. Lineweaver compared their results to a car's gas tank. He states, 'It's a bit like looking at your gas gauge and saying "I thought I had half a gas tank, but I only have a quarter of a tank."'" Fortunately, that quarter of a tank will still get us as far as we need to go and then some.

for the past several years I've been mailing all my feces to Ron Paul. Every time I defecate, I do so in a zip lock bag, which I then send to Ron Paul's home address via USPS priority mail. Though I always clearly write my name and address on the return portion of the envelope, I have never received a reply, nor have any of my mailings been refused.

Way I see it is that proposed cap and trade taxes will make it too expensive to live in this universe... Sure, they want to start out here at home, then a global treaty, next will be the universal treaty for taxing energy use. I'd hate to see what the tax rate is on all that "FREE" sunshine from our local star. Once the Intersteller cap and trade program goes into effect, I think we are all better off with a towel.

Entropy is actually "the old CO2". Enough of the fundamentals of thermodynamics had been worked out by the Victorian period that the prospect of the "heat death" of the universe became visible. Life is a comparatively low entropy state. Entropy in a closed system increases over time. Game over, man. Game over. There was a certain amount of fretting about this.

Nobody(outside of physicists doing thought experiments and Kurzweil planning his next move) really cares anymore; because subsequent research has uncovered such a long list of stuff that will almost definitely kill us before the heat death of the universe does.

Aside from all the human sacrifice and slavery and misogyny...

Hmm, let's put this together shall we? When people's lifetimes were extended they had more time to think, become wiser, less concerned with death and the future of their progeny, all in all became less barbaric... hmm... maybe the trend would continue?

The universe could go back to low entropy (4, Interesting)

Viol8 (599362) | more than 4 years ago | (#30904328)

Just because the laws of physics IN THIS UNIVERSE prevent that doesn't mean it can't happen since by definition the low entropy state the universe started in was created (in some form) by alternative laws of physics possibly outside this universe since the laws we know didn't exist at that point.

There's no reason why these alternative physical laws couldn't suddenly kick back in when the universe reaches a certain entropy state and start to reverse the whole process back to zero. Some people would say time would then be going in reverse but this doesn't need to be the case.

two possible futures now cut shorter.... (5, Interesting)

rubycodez (864176) | more than 4 years ago | (#30904412)

Star formation is believed to end about 10^14 years from now, the total entropy of universe only affects events after that. Not a worry. If protons decay with 10^32 year half-life, then practically all nucleons decay after 10^40 years, which leaves all black holes to evaporate after about 10^99 years.

If protons don't decay as we suspect, then universe slowly tunnels to iron-56, (light nuclei via fusion and heavier via fission) in about 10^1500 years, which coalesce into black holes or neutron stars in about 10^10^76 years (yup, double exponent).

So quite frankly, this bit about more entropy means little for life as we know it, though if life can arise by some heat-engine powered means (due to temperature differences only). still the time scales are staggering.

heat death (1)

astar (203020) | more than 4 years ago | (#30905304)

I liked the post above a lot.

Heat death arguments are all about the laws of thermodynamics and there are probably three good criticisms.

the experimental basis last i looked was some system in equillibrium with a container around it and instrumentation outside the container. so in the heat death argument there is an implication that the universe is in equillibrium and the idea of a container and an observer outside the universe is a meaniful concept. To be clear, I am not particularly looking here at something simple like feasibility. I am fine with thought experiments up to a point.

there is a parallel assumption, very deep in the usual science and a lot of math, that the universe is a machine.

emperically, thermodynamics is fundamentally wrong. consider events around the end of the 19th century. thermodynamics was around. the equations were established. in fact, there was, based on a flakey idea that physics was finite, the thought that we knew everything. There were a few unimportant oddities. One of them was radioactivity. so the thermo equations on the blackboard got rewritten. right at that point, thermodynamics did not hold. so what does this say about the fundamental nature of the universe?

Re:heat death (3, Informative)

khallow (566160) | more than 4 years ago | (#30906066)

"The universe is a machine." What does that mean? That the universe is deterministic? There may well be some sort of as yet, undiscovered observer (the unobserved observer?) for which the universe is indeed wholly deterministic.

emperically, thermodynamics is fundamentally wrong. consider events around the end of the 19th century. thermodynamics was around. the equations were established. in fact, there was, based on a flakey idea that physics was finite, the thought that we knew everything.

One of them was radioactivity. so the thermo equations on the blackboard got rewritten. right at that point, thermodynamics did not hold. so what does this say about the fundamental nature of the universe?

The only thing that thermodynamics can't explain is why aren't we already at maximum entropy? Everything else that we know of (such as radioactivity) is fully consistent with thermodynamics.

1) It's a dupe.
2) The article it refers to hasn't been published/peer reviewed yet.
3) Finding out we have 350 quadrillion years to go instead of 700 quadrillion years, is utterly meaningless at this point, since estimates that far wide and ranging will doubtless change a LOT in the X million years it will be before it becomes even remotely meaningful to human science.

Our ignorance about super massive black holes, and the number of them in the universe, already set the error bars on any estimate far too wide for it to be meaningful to even talk about it.

I haven't been this non-excited since they moved the estimates of Graham's Number [wikipedia.org] from 6 < N* < N to 11 < N* < N.

Singularities are not a requirement of black holes.

Black holes can contain lots of usable energy, for those that might be in the black holes.

So the difference between a quarter and half of a tank is "An order of magnitude"?

Nadaka (224565) | more than 4 years ago | (#30905220)

it is... in base 2.

you assume that tank-fullness linear?!

There are only 10 types of people, those that understand binary...

(the difference between a quarter and a half is an order of magnitude, a binary order of magnitude that is...)

The ori blackhole powered super gates are speeding it up.

Can someone prove to me the method by which energy becomes unable to do any work?

I am very curious about how such an event is even possible, and what the evidence is to suggest that it's actually happening.

Global warming again? (0, Redundant)

It's that global warming stuff again.

We need to ban SUV's (only type of car that causes global warming), and buy carbon credits from Algore. That will fix this problem, just like here onm Earth!

Speed increase or decrease? (1)

PietjeJantje (917584) | more than 4 years ago | (#30905480)

The question is, if our tank is 95% empty, would the speed increase because the black holes become greedy, or decrease because what's in between is too far away?

Your question:

How can entropy be reversed?

Returned the following results:

THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER

how far? (1)

Ephemeriis (315124) | more than 4 years ago | (#30905702)

Fortunately, that quarter of a tank will still get us as far as we need to go and then some.

And just how far is it that we need to go?

I understand that the universe will out-live me by several orders of magnitude... And my children... And my children's children... Etc...

I understand that the Earth will be consumed by our sun long before the universe dies...

But I'm just wondering what "as far as we need to go" means...

It's not the heat... (1)

It's the humidity.

Don't worry.... (0)

Don't worry, surely the UN, Obama, Green Piece and China can solve this if they really try. I mean surely we awful humans have caused this. We are so disorganized and chaotic And we can all do our part by tidying up a little around the house. Every little bit counts right? I'm going to clean off my desk right now and I'm sure there is somewhere I can buy Intropy Credits to vicariously assuage my vicarious guilt.

You down with entropy? Yeah, you know me! (0)

Trash Talk
Harm me with harmony.
Doomsday, drop a load on 'em.

Verse 1
Entropy, how can I explain it? I'll take it frame by frame it,
to have you all jumping, shouting saying it.
Let's just say that it's a measure of disorder,
in a system that is closed, like with a border.
It's sorta, like a, well a measurement of randomness,
proposed in 1850 by a German, but wait I digress.
"What the fuck is entropy?", I here the people still exclaiming,
it seems I gotta start the explaining.

You ever drop an egg and on the floor you see it break?
You go and get a mop so you can clean up your mistake.
But did you ever stop to ponder why we know it's true,
if you drop a broken egg you will not get an egg that's new.

That's entropy or E-N-T-R-O to the P to the Y,
the reason why the sun will one day all burn out and die.
Order from disorder is a scientific rarity,
allow me to explain it with a little bit more clarity.
Did I say rarity? I meant impossibility,
at least in a closed system there will always be more entropy.
That's entropy and I hope that you're all down with it,
if you are here's your membership.

Chorus
You down with entropy?
Yeah, you know me! (x3)
Who's down with entropy?
Every last homey!

Verse 2
Defining entropy as disorder's not complete,
'cause disorder as a definition doesn't cover heat.
So my first definition I would now like to withdraw,
and offer one that fits thermodynamics second law.
First we need to understand that entropy is energy,
energy that can't be used to state it more specifically.
In a closed system entropy always goes up,
that's the second law, now you know what's up.

You can't win, you can't break even, you can't leave the game,
'cause entropy will take it all 'though it seems a shame.
The second law, as we now know, is quite clear to state,
that entropy must increase and not dissipate.

Creationists always try to use the second law,
to disprove evolution, but their theory has a flaw.
The second law is quite precise about where it applies,
only in a closed system must the entropy count rise.
The earth's not a closed system' it's powered by the sun,
so fuck the damn creationists, Doomsday get my gun!
That, in a nutshell, is what entropy's about,
you're now down with a discount.

Chorus

Trash Talk
Hit it!
Doomsday, kick it in!
