I'm not a physicist. In fact I ran a bar. That is a difficult business in Berlin and I got a lot of worries, that kept me awake many nights. This led to a deviation to some kind of use for that time and I started to develop an idea I had earlier. It was just a kind of hobby and had no porpoise at all. It goes like this:
If we start from relativity and try to connect it to quantum-mechanics, we first have to make spacetime three-dimensional, because our observed world is three-dimensional. I said, string-theory can't possibly be true, because we don't experience ten (or more) dimensions. This is so, because the term 'dimension' refers to various topics, but one could say dimensions are the possible numbers of degrees of freedom. Since with any dimension we add a lot of degrees of freedom, ten dimensions are absolutely not possible.
For some reasons I stumbled over quaternions and that worked. You must try it yourself, to make you convinced. It is quite easy:
Imagine symmetry. Our observed world is symmetric. Makes no much difference, if we move back or forth, but it makes a difference, if we move up or down. Spacetime is antisymmetrric and space isn't. How put that together?
Imagine everything to turn left if it goes through space and imagine being a part of that -well- patterns. You would certainly experience the world from your own state of being. This should be a world, wherever you go and how fast. This is the essence of relativity. There is no such thing as absolute space and where ever you go, your observation will be based on your own state of being.
That is in fact counter-intuitive, but it is a proven(!) fact.
Now antisymmetry makes everything of opposite sign, if you change the direction. In spacetime-diagrams we could say; left is negative and right is positive (or any other duality names). As a matter of fact our world is not two dimensional but three dimensional and we must extend duality to triality. With such a model it is possible to model particles, just out of 'directions' of antisymmetry. It is pretty counter-intuitive, this is why I can just ask you to try that yourself.
Being there, it is easy to think the earth could expand. If the 'particle concept' doesn't hold, we would have to think in different terms. The particle concept is a corner stone of modern science and to abandon it, is next to impossible. But - that is my personal point of view - we have to.
