the universe as a 4-dimensional spherical wave
« on: 13/07/2011 06:37:29 »
The Minkowski spacetime represents a 4-dimensional space with time as an imaginary dimension.  That would be a seminormed space, contrary to the normed Euclidian space that we perceive.  I think that the Minkowski spacetime is thought of as a mere mathematical model but our universe could actually exist in such a seminormed 4-dimensional space.  With that assumption, our universe could then be a 4-dimensional spherical wave with an imaginary radius, propagating at the speed of light.  This would explain the expansion of the universe and it would explain the big bang as the source of the wave.

This model would even explain why we perceive only three dimensions when there are obviously more of them.  Our universe being the actual wave and not just occupying the space of the wave, we are constrained within this phenomenon.

Just as an analogy, a ripple on the surface of a pond would correspond to a unidimensional universe and its big bang could be a rock that was dropped in the water from outside of the plane that contains this "universe".

Of course, this raises many questions, the most important one being what is the physical property that varies with the wave.  But leaving aside the unanswered questions, this looks to me like an intuitively sound model for the universe.  Anyone heard of something similar and what do you guys think about it?

I'm not sure what seminormed means, but I will say that if you think you have a theory of the universe, then the first thing to do is to apply this theory to the prevailing problems in physics and see what you get.

If this theory can explain things like time dilation, curvature of spacetime, the double slit experiment, dark matter/energy etc. then those explanations are probably going to be, at least initially, more worthwhile to consider.

The Universe as a wave.
I'm not sure this concept constitutes a new "Theory for the Universe", and would need to be defended as such. Rather, or at least as I understand it. It creates a new model for visualizing the universe as if from a 5 dimensional vantage or some point outside our universe. This vantage is not limited by our perception of time, allowing the universe in all moments of time to be visible at once. The result is all matter, even subatomic particles in the universe would be observed as strings or waves. All attractive forces, which we perceive in time, as elliptical orbits would be transformed into waves by the rapid expansion of the universe. Thus the Universe We observe is very much like a ripple in a pool of water. I don't see how this can be refuted. What this would explain I'm not sure, other than inferring that gravity or any attractive force (things still not completely understood) would be better understood as a wave phenomena. If it's not insightful it is an elegant even poetic way of visualizing our universe.
