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

One of the more exciting ideas in high energy physics is the possibility that our three-dimensional universe is embedded in a much bigger multidimensional cosmos. Physicists call these embedded universes “branes” and say that it should be possible for stuff from our brane to leak into other branes nearby and vice versa.

Today, Michael Sarrazin at the University of Namur in Belgium and a few pals say they have worked out to detect this leakage by measuring whether neutrons can bypass barriers by leaping into another brane and back again.

These guys are proposing to measure this effect by placing a neutron detector close to a nuclear reactor to see whether neutrons appear unexpectedly as a result of being transported out of the reactor via another braneworld.

The theory is straightforward. Sarrazin and co say that braneworld theories predict that particles such as neutrons can exist in our brane and another at the same time, in a superposition of states.

When these neutrons are disturbed by, say, a collision with a nuclei, the superposition is destroyed and the neutron ends up with a certain probability in one brane or the other. This is the process that allows neutrons to leak in and out of branes.

But why just neutrons? Why not whole atoms? Or compounds? Or whole organisms?

It's hard to suppress the imaginings that come with this idea.

... to see if photons emerge on the other side of a barrier. It has to be an "entangled" particle, and I believe I read that molecules as large as buckyballs have been shown to be entangled.

The reason I found this article fascinating was that I've always thought that "multi-universe" hypotheses could not be tested and were therefore not really scientific.

Since a change in one particle can instantly affect another entangled particle no matter how far away they are, if they were connected through a different universe, (or brane?) where they are touching it could explain how the change could travel faster than light within our universe. They are kind of peeking through to our universe but actually exist in the other one.

That multiple branes are in an unimaginable universe of branes , somewhat analogous to onion layers. Some of these branes are matter, some anti-matter, some matter we cannot fathom (multi-dimensional - multi material). When these branes collide, a big bang occurs forming another brane which may be something new.

... with a certain probability in only 1 brane, how does that result in energy leakage, since the neutron was already in that brane to begin with?

I bet the scientists will be kicking themselves when they realize that's all they needed.

I just could not resist some lame political commentary. Fascinating. If travel ever becomes possible I would like to find a place where Homo Sapiens made some better choices.
