The Universe Damaged By Observation?

ScentCone writes "The Telegraph covers a New Scientist report about two US cosmologists who suggest that, a la Schrodinger's possibly unhappy cat, the act of observing certain facets of our universe may have shortened its life . From the article: 'Prof Krauss says that the measurement of the light from supernovae in 1998, which provided evidence of dark energy, may have reset the decay of the void to zero — back to a point when the likelihood of its surviving was falling rapidly.'"

      It isn't observation by a sentient being that causes the wave function to collapse, its interaction. The point being made by Schroedinger is that observation inescapably means interaction and thus affecting the quantity being measured.

      light from the supernova would be interacting with the earth regardless of whether scientists were there.

      When you think about it that way, it does seem ridiculous... some interpretations of quantum mechanics (for example, the "Many Worlds" model, explained below) may help understand how this could possibly be. Indeed, this is why some people dislike the typical view of quantum mechanics (the "Copenhagen Model"), as there are experiments that show that this does in fact change things.

      The most straight-forward example (that doesn't involve murdering cats) is the double-slit experiment. You send a coherent beam of light (or electrons, it turns out, although that particular experiment is harder) at a screen with two slits in it, and observe what pattern appears on the wall behind it. With just one slit, a particular pattern (a diffraction pattern) appears. But with both slits in place, you see characteristic alternating bands of light and dark (an interference pattern). The weird part comes if you place a detector in the slit (that still allows the light to pass through), to try to see which slit each photon goes through. If you do that, the intereference pattern disappears! Somehow, the act of passively measuring the photon (which is just EM radiation under a different name) with scientific instruments changes the fundamental character of the interaction - that is, you "collapse the wave function."

      While measuring the whole universe does indeed sound much more ridiculous than a table-top experiment, the point is just that the axioms of quantum mechanics, when applied to the universe as a whole, give this result. Now, this could mean there's something wrong with the way we model dark energy... my money is on this one, seeing as how we actually have no consistent theory at all of how Dark Energy works. This article is based on 2 or 3 assumptions that have not at all been established as anything other than theories that might work (and there are far more theories that also work and don't tell you that we're destroying the universe).

      Alternatively, though, this could mean we don't understand quantum mechanics (in fact, we KNOW that it's wrong when it comes to gravity, for other reasons) or at least that the Copenhagen model is incorrect. An attractive (to some people) model is the "Many Worlds" model. According to this interpretation, instead of the universe reacting to our measurements, there are universes created every time a measurement is made for each of the possible outcomes of the measurement. So measuring the acceleration of Dark Energy, in this interpretation, doesn't change the universe directly - instead, it simply selects one out of many possible universes for YOU to inhabit. From that viewpoint, it makes much more sense how observation can affect things that you are not directly controlling - you just pick where you're doing your observation from, rather than changing the thing that you are observing.

    5. Re:On first glance... by ETEQ · · Score: 5, Insightful

      This may be physically true, but the theoretical framework of quantum mechanics does not require it. This is why this Dark Energy test is an interesting point to make. Most astrophysicists will probably agree that it sounds rather ridiculous, but the point is that the way Dark Energy is theoretically modeled by some people (e.g. a quantized scalar field, probably in a false vacuum), the result is as the article describes.

      That is to say, you need not postulate anything about how a photon interacts with a detector to still get the strange result in the double-slit experiment. Just say that the measurement collapses the wave function (e.g. fixes it to a definite eigenstate), and you get the results observed. So it isn't all in the details about the interaction - there's something going on that applies rather well in general to all quantum mechanical interactions.

      To sum up, "observation changest things" is not a "mystification," but rather a way to generalize what's going on and develop a theoretical framework (which, incidentally, is quantitatively by far the best verified theory science has ever created).

      Several years back I read about an experiment I would have thought would be authoritative on this. It was a classic split-beam type of thing, with detectors that could determine which path the photon went down. In normal circumstances, when you insert the detectors, the interference pattern goes away and you get a classical distribution. When you remove the detectors, you get an interference pattern in the quantum mechanical distribution.

      That's all wellandgood, but here's the twist. They inserted the detectors, and disconnected the outputs from any sort of meter or display device. Therefore the detectors "observed," but no conscious knowledge could be gained.

      The interference pattern went away, and they got a classical distribution.

      IMHO, the wave "collapses" when the potential error exceeds Heisenberg's limit, and that constitutes "observation." Most any other answer makes a special place for consciousness in the universe, and cascades into telepathy, clairvoyance, the Force, etc.
