There are infinite numbers so that means there are infinite frequencys
This means there are infinite frequencys a superstring(infinite tetrahedron grid) can have
This means there are infinite dimensions
The superstrings that make up the dimension you are in are 7 dimensions higher(the 3 dimension is made out of superstring vibrating in the 10 dimension )
There are 12 vibrational dimensions with infinite dimensions in between
After the 12 vibrational dimensions there are infinite sub multidimensional levels
