>>12365726there is a very convincing proof that there can only be three space dimensions.
only with three space dimensions the F ? 1/r2 laws of forces apply. r := distance
stable planetary orbits are only possible in three spatial dimensions.
and then we have the time (yes as inseparable space-time but still the time).
so we actually know two different types of dimensions.
and then we make theories but do not distinguish.
of course we can now 'roll things up' and keep them away from us.
but what is that then?
what purpose does it serve?
and why should there be more at all?
arent we rather looking for mathematical forms, only to have a unified theory on the paper?
why should we unite forces that show so clearly that they are not made of the same?
electromagnetism, for example, can be completely manipulated.
gravity does not care.
and both obey the 1/r2 law but because of space/spacetime, see above.
so there are grotesque differences.
for my understanding we are exposed to a very basic duality here.
and this includes phenomena that are not present in quantum field theory or GR (dark energy and matter for example).
so we try to solve a problem with a unified theory, which is obviously not complete.
and I am convinced that this duality can only be understood when we understand these phenomenas.
then and only then we might be able to succesfully unify theories.
