Decide for yourself.

*My thesis now is that a p-dimensional world has a p+q dimensional unity, for instance, 2 dots (or more possibly along the 1D surface) has a 1D line as a unity, 2 lines (or more along the same 2D surface) has a 2D surface as a unity. 2 surfaces has a 3D space as a unity, 2 rooms has a 4D time space as a unity. But if there were more then 2 dots, then possibly a 2D or even nD surface would be the unity of the dots, it is a nD dot. Perhaps the universe started with an n:dimensional dot, and an n:dimensional dot has a unity in the n:th dimension. But perhaps an n:dimensional dot requires that in an n-q dimensional world there are exactly (or likely, since momentum&vektor&energy is preserved) >2^q (n-q):dimensional objects given that there could only be 2 (n-1):dimensional objects, that is 2^(n-X) X-dimensional objects. And since every dimension has atleast a beginning and an end, the n-dimensional particle being the only exception. But then what is a dot? Know that a dot in a fourdimensional world, a particle, is a 4D dot, a 4D object, just like an n:dimensional world had this n:dimensional dot, this unity. A 4D world, as our own, does have p^(n-3) particles, but only p^(n-4) 4D dots, 4D-particles. A 4D dot seen along a one dimensional line is not one dot, it is 2 1D dots, and not all dots can be seen, since they are not all along the line, But it is also true that in a 3D room you can only see the 3D expression of a 4D-particle, hence what we see is a 3D particle, and 4D particles are fewer then the 3D particles, and we cannot see their entirety from where we are. There are 2 3D expression particles along every 4D particle lifetime line, one in the beginning and one in the end. This all given, "the number of the planck particles in the universe" is 2^(D-3) = e^(ln(2)(D-3)), you can get D by logarithming both sides then divide with ln(2) and then add 3. But I just thought this up, it don't have to be right. Comments on this would be appreciated*
