I believe the dual slit experiment proves that single photons and even buckyballs have to interfere with something right ? Even if it's only themselves ? So is it possible that they could be interfering with coppies of themselves from other dimensions ? Maybe 20 of them, as proposed by string theory ?

Thing is, I also believe that baryonic matter only makes up about 5% of the Universe ? Or 1/20th of it. Is that just crazy coincidence ? Or is there some special significance or reason for the figure of 5% ? Could the other 95% be 'locked away' in 19 'other dimensions' that interfere with ours whilst remaining to all intents and purposes invisible to us ?

Just wondered if this has been answered ? Or if it's even a valid question...?

String Theory and the presence of so many multiple dimensions is a highly theoretical subject, so it's hard to tackle. My understanding of quantum mechanics is that particles in the double slit experiment interfere with themselves. All matter is supposed to have a dual nature, taking on characteristics of a wave and a particle. If you do the QM calculations and diagrams for a particle, like an electron, going through a double slit, you'll see that the wave function of the electron diffracts through both slits, as a wave should, and interferes with itself, no extra dimensions seem to be needed.

As for the Baryonic Matter ratio, I don't think scientists have a definite, calculated number for exactly how much matter in the universe is baryonic. It could be exactly 5%, (unlikely), it could be 4.9857485%, or anything in the relative vicinity, you get the picture. It's probably not a really simple number, if you were to be able to really calculate it precisely, just like any other constant of nature, so no, I don't believe it is a coincidence. As for matter locked away in other dimensions we can't see, that's a pretty cutting-edge question, I wouldn't be qualified to answer it, I don't anyone is.
 
Thanks, I see what you mean. I shall ponder some more. I just thought it would be a neat solution for dark matter, dark energy, wave/particle self interference etc? I mean, if there really were multiple 'invisible particles/waves' from other dimentions that interacted in certain ways with the visible ones in ours it could explain a lot ?

I was just wondering if anybody had worked out if it was possible or not. Or if such a thing is even possible to work out in the first place.

Sorry but I have a habit of asking crazy questions :)
