No I am not increasing the size 27 times. There is a difference between size and volume. If you increase the size of a 3D item, that automatically implies increasing it in length, width and height, unless specifically requested to increase in one dimension only.

According to my dictionary an increase in size can refer to an increase in either spatial dimensions or bulk. If I had been talking about spatial dimensions you would be correct, but I was not. I was talking about bulk. There can be a three times increase in bulk within a range of many different spatial dimensions. Three times the increase in bulk could result in double the spatial dimensions or it could be one hundred times.

As far as spatial dimension goes this universe has had a number of different spatial dimensions while maintaining approximately the same number of atoms.

Rick:

Your sentence should have read "...triple the volume and density".

Triple the density (or number) of atoms may have better qualified what I meant, but triple the volume would have been incorrect as the universe varies in volume over a period of time.

Rick:

But that still sounds wrong, because triple the number of inhabitants brings the number to three living in 3 cubic units, versus 1 living in 1 cubic unit. The density is still the same, or am I missing something.

My writing was referring to an increase in mass of the whole, not an increase in density per square inch. Perhaps I should clarify this in a future edition.
