Astronomy Without A Telescope – Holographic Dark Information Energy

Holographic Dark Information Energy gets my vote for the best mix of arcane theoretical concepts expressed in the shortest number of words – and just to keep it interesting, it’s mostly about entropy.

The second law of thermodynamics requires that the entropy of a closed system cannot decrease. So drop a chunk of ice in a hot bath and the second law requires that the ice melts and the bath water cools – moving the system from a state of thermal disequilibrium (low entropy) towards a state of thermal equilibrium (high entropy). In an isolated system (or an isolated bath) this process can only move in one direction and is irreversible.

A similar idea exists within information theory. Landauer’s principle has it that any logically irreversible manipulation of information, such as erasing one bit of information, equates to an increase in entropy.

So for example, if you keep photocopying the photocopy you just made of an image, the information in that image degrades and is eventually lost. But Landauer’s principle has it that the information is not so much lost, as converted into energy that is dissipated away by the irreversible act of copying a copy.

Translating this thinking into a cosmology, Gough proposes that as the universe expands and density declines, information-rich processes like star formation also decline. Or to put it in more conventional terms – as the universe expands, entropy increases since the energy density of the universe is being steadily dissipated across a greater volume. Also, there are less opportunities for gravity to generate low entropy processes like star formation.

The link between entropy and information - more interesting and information-rich things occur in low entropy states than in high entropy states.

So in an expanding universe there is a loss of information – and by Landauer’s principle this loss of information should release dissipated energy – and Gough claims that this dissipated energy accounts for the dark energy component of the current standard model of universe.

There are rational objections to this proposal. Landauer’s principle is really an expression of entropy in information systems – which can be mathematically modeled as though they were thermodynamic systems. It’s a bold claim to say this has a physical reality and a loss of information actually does release energy – and since Landauer’s principle expresses this as heat energy, wouldn’t it then be detectable (i.e. not dark)?

There is some experimental evidence of information loss releasing energy, but arguably it is just conversion of one form of energy to another – the information loss aspect of it just representing the transition from low to high entropy, as required by the second law of thermodynamics. Gough’s proposal requires that ‘new’ energy is introduced into the universe out of nowhere – although to be fair, that is pretty much what the current mainstream dark energy hypothesis requires as well.

Nonetheless, Gough alleges that the math of information energy does a much better job of accounting for dark energy than the traditional quantum vacuum energy hypothesis which predicts that there should be 120 orders of magnitude more dark energy in the universe than there apparently is.

Gough calculates that the information energy in the current era of the universe should be about 3 times its current mass-energy contents – which closely aligns with the current standard model of 74% dark energy + 26% everything else.

Invoking the holographic principle doesn’t add a lot to the physics of Gough’s argument – presumably it’s in there to make the math easier to manage by removing one dimension. The holographic principle has it that all the information about physical phenomena taking place within a 3D region of space can be contained on a 2D surface bounding that region of space. This, like information theory and entropy, is something that string theorists spend a lot of time grappling with – not that there’s anything wrong with that.

This article reminded me of a song by John Lennon called Mind Games, which I copy here for your amusement… “We’re playing those mind games together, Pushing barriers, planting seeds, Playing the mind guerilla, Chanting the Mantra peace on earth, We all been playing mind games forever, Some kinda druid dudes lifting the veil. Doing the mind guerilla, Some call it the search for the grail, Love is the answer and you know that for sure, Love is flower you got to let it, you got to let it grow, So keep on playing those mind games together, Faith in the future outta the now, You just can’t beat on those mind guerillas, Absolute elsewhere in the stones… Read more »

Without High Entropy humans would not exist to ponder this conundrum. (For fun, here is a hypothetical train of thought) Sentience reduces entropy by coding higher levels of complexity. (*1 “The problem of organization in living systems increasing despite the second law is known as the Schrödinger paradox” One might assume that other sentiences in the universe (should they exist) do the same regardless of biology. Sentience thus might be thought of as an entropy trap, by coding the physical universe into a state of ordered reality or equilibrium. The one perplexing part is what happens to this encoded information when a person dies. (if anything) Dark energy could be the transmuted sentience ? Thus preserving the second… Read more »

In the purely physical world yes, Physicists do rather prefer a more classical definition. To quote Schrödinger. “Let me say first, that if I had been catering for them [physicists] alone I should have let the discussion turn on free energy instead. It is the more familiar notion in this context. But this highly technical term seemed linguistically too near to energy for making the average reader alive to the contrast between the two things” Im not here to defend the viewpoint, merely to point out that it has been considered before. My own interpretation is an intellectual muse. It cant be proven in any way I can imagine, so its at best a branch of study veering… Read more »

Did I say that? Sorry I was quoting the concept of Negentropy.
http://en.wikipedia.org/wiki/Negentropy

Which is not a depiction of my belief, simply a facet of Information Theory. As far as I know its not considered a Pseudo science.

I thought it was pertinent to Gough’s interpretation of free energy. Or at least that it presented another viewpoint on the matter.

Im not explaining it very well obviously. Lets move back to the world of Physics.

It is pretty much tied only to pseudoscience, see your own reference (“organization theory”).

Since negentropy doesn’t reflect the actual physics but obfuscates it by replacing actual entropy change with a model of a flow _in the wrong direction_ it has found very little actual use.

It isn’t an actual paradox any more than the twin paradox or the EPR paradox, you know: the solution is in the formulation. Life isn’t very ordered, nor much producing entropy; cell entropy production is bounded by rust from below and methane burning from above. The amount of entropy produced by cell growth is far less than entropy produced by sun light hitting and then dispersing from Earth’s surface. Sentience reduces entropy by coding higher levels of complexity. This is a deepity. That does “coding” mean here? If you get back to biology, the entropy production from apparent complexity of evolution is order of magnitude less than the entropy production of cell growth; it is ~ 10^-10 of… Read more »

Wow, a discussion about entropy that doesn’t increase the disorder of my stomach! =D The tie in between the holographic principle and Landauer’s principle is, if not problematic (more below) so the correct way as I understand it. Gough’s predictions: ———————— I looked briefly on Gough’s work, and while I think it is wrong (more below) we should start out by asking what he predicts and how it connects with earlier theory. Gough connects entropy over Landauer’s principle to energy. In table 1 Gough (and his 3x prediction) lists several energy contributions from various parts of the universe. We can note that they are roughly the same. I think this is to be expected and can be predicted… Read more »

I am decreasing entropy by simply thinking about this.
Right?

What is holographic entropy? The author Michael Gough makes a case that the entropy of the universe is comparable to the entropy of the universe at large. This should not be that surprising. The observable universe has a type of event horizon, similar to a black h ole horizon. The one difference is this horizon appears to any observer as what the black hole horizon might appear to an observer inside the black hole looking outwards. The event horizon defines the entropy of the system according to its area. In the case of a black hole the larger the area of the black hole the larger its entropy. A large black hole conceals more microstates than a small… Read more »

There already is another theory by our team linking dark energy with Landauer’s principle and holography . arXiv:0709.0047 , What you describe here is very similar to our model.

Indeed your paper is remarkably similar to this. The cosmological horizon should be reduced from the Bekenstein or holographic bound. I am not sure about the observational status of z = 1 galaxies. Yet a decent survey with some other ruler measure should hone in on this.
