The Search For Neutrons That Leak Into Our World From Other Universes

KentuckyFC writes: One of the more exciting predictions from "braneworld" theories of high energy physics is that matter can leak out of other universes into our own, and vice versa. The basic idea is that our three-dimensional universe or brane is embedded in a much larger multi-dimensional cosmos. These branes can become coupled so that a quantum particle such as a neutron can exist in a superposition of states in both universes at the same time. When the neutron collides with something, the superposition collapses and the particle must suddenly exist in one brane or the other. That means neutrons from our universe can leak into other branes and then back again. Now physicists are devising an experiment to look for this neutron leakage. They plan to put a well shielded neutron detector next to a shielded nuclear reactor that produces neutrons at a research facility in France. All this shielding means the detector should not see any neutrons from inside the reactor. However, if the neutrons are leaking into another brane and then back into our world, they can bypass this shielding and trigger the detector. The team has not yet set a date for the experiment but the discovery of neutrons (or anything else) leaking into our universe would be huge.

      Socks too. Jobs. And women.

      Actually where socks go has already been well investigated.

      The little known fact is that socks are actually the larval form of hangars, which makes perfect sense, you always find socks missing but check your closet.. and you find that you have many more hangars than you accounted for. Mystery was solved back in 09.

    We need to build a fence to keep these undocumented neutrons out of our Universe and from taking jobs from our neutrons. # IAmNotAScientist

      Even worse... what happens when those undocumented neutrons get together and create anchor hadrons.

      Who's going to pay for those?

      You just set up the computer controlling the experiment to create a bunch of zombie processes. They'll eat the branes...

      We can smash the large hadrons, it's the small and medium ones I'm worried about...

    Is neutron leakage ruining your day?

    Well, no more! Now with my patented genuine neutron pads neutron leakage will be a thing of the past!

    We use only the purest boron from the banks of Rio Tinto to absorb your stray neutrons*.

    *Neutrons from other universes are not covered by this product. If the neutron flux is higher than the OHSA limits, bend over and kiss your ass goodbye.
