Scientists Are Using Subatomic Particles To Search For a Mirror Universe (nbcnews.com) 212

Posted by BeauHD from the lost-in-plain-sight dept.
An anonymous reader quotes a report from NBC News: At Oak Ridge National Laboratory in eastern Tennessee, physicist Leah Broussard is trying to open a portal to a parallel universe. She calls it an "oscillation" that would lead her to "mirror matter," but the idea is fundamentally the same. In a series of experiments she plans to run at Oak Ridge this summer, Broussard will send a beam of subatomic particles down a 50-foot tunnel, past a ring-shaped magnet and into an impenetrable wall. If the setup is just right -- and if the universe cooperates -- some of those particles will transform into mirror-image versions of themselves, allowing them to tunnel right through the wall. And if that happens, Broussard will have uncovered the first evidence of a mirror world right alongside our own.

The mirror world, assuming it exists, would have its own laws of mirror-physics and its own mirror-history. You wouldn't find a mirror version of yourself there (and no evil Spock with a goatee -- sorry "Star Trek" fans). But current theory allows that you might find mirror atoms and mirror rocks, maybe even mirror planets and stars. Collectively, they could form an entire shadow world, just as real as our own but almost completely cut off from us. Broussard says her initial search for the mirror world won't be especially difficult. But if she unequivocally detects even a single mirror particle, it would prove that the visible universe is only half of what is out there -- and that the known laws of physics are only half of a much broader set of rules.

    I had not heard of this Theory of Mirror Matter [wikipedia.org]. tldr; explains some unusual observations and mirror matter is a candidate for the mysterious missing mass of the universe.
    • The problem with this is that mirror matter only is hypothesized to interact weakly with normal matter, its own exchange bosons should interact normally (or far more substantially). The problem with this is the way in which dark matter dosent clump or experience "friction" like the bullet cluster example where it simply passes through itself. Further it wouldn't explain the large symmetrical bulge of it around galaxies but instead it would clump up more like regular matter. So while it's a wimp and that'

        Personally, I favor a theory that postulates about 9 alternative universes, enough to account for almost all the dark matter. They would each seem normal to themselves. And there would be a leakage of gravitation between the universes, explaining part of why gravity is such a weak force. This would cause most of the large masses in the parallel universes to tend to cluster near each other, but since there'd be essentially no inter-universal friction, they'd keep oscillating rather than slow down.

        I'd elab

        • You don't have to be an expert to see that wouldn't fit observation. The dark matter lacks the clumping of normal matter. Hence weakly interacting, both with itself and normal matter. It is mathematically equivelant to wimps, if you want to talk math.

            Sorry, but that's not clear at all. If you have 9 clumps of non-interacting matter oscillating around their common center of gravity, and the clumps of mass are not tightly bound (i.e., they are extended in space), then it's not clear that you wouldn't see something that looked fuzzily distributed. It would, however, predict that there was no strongly consistent relationship between observable matter and the "dark matter", but only a weak relationship. I.e., observations much more probabilistic than det

            • You are forgetting that in each of these states the majority of the material would be gas and clump up. The bullet cluster is a great example of how your example dosent hold on large scales.
              • Also we were talking the mirror matter hypothesis, of which there is a single other state. Not 9.
            • here [arxiv.org] is a good paper to read if you want to see why people think wimps are weakly interacting with themselves. There is empirical proof to 8 sigma; though it is nice to have many many examples, it's also hard to explain this away with only handwavi g.

                Yes, but that wouldn't disagree with my proposal at all...or if it would, the reason why is not at all clear to me.

                • Two reasons. First, if it's just symmetry, there is one other possible state, not 9. Second, the other mirror matter would be nearly indistinguishable from normal matter in terms of how it interacts with itself, just like antimatter. It interacts with itself just like regular matter.

                  The bullet cluster is a good illustration of how this "dark matter" is cold after a collision I.e. Weakly interacting. They use this as the premise for thier models and attempt to explain the results through modeling.

                    Yes, but the place I start disagreeing is with the first supposition. If there's any evidence that it's "just symmetry", then I don't know what it is. I'll agree that the "just symmetry" model has been well developed, but the evidence seems sketchy enough that while there's good evidence that something is there, the evidence of what's there is just about absent. We can tell "it sort of acts like matter" and "we can't see it", and "it tends to cluster where mass that we can see clusters", and this is an e

                    • Ok I see, I was talking about this article and the OP which linked to the Wikipedia entry for mirror symmetry hypothesis, not for all dark matter hypothesis. Hypothesis like the mirror matter that don't have it interacting with itself weakly are falling quickly out of favor because of the actual observations we can now see, and instances like the bullet cluster keep being observed so we now know it's not some one off outlier but rather a typical occurrence in these situations.

                      We can tell "it sort of acts like matter" and "we can't see it", and "it tends to cluster where mass that we can see clusters", and this is an example of why "tend" is the correct word to use.
