Perfect vacuum is just the origin of our reference frame of space. It is not the absolute zero. It means that space can be negative too. At least to some extent if not to the negative infinitive.

Square-root of -1 is 'i', which shows that 'i' is the length of a side of square of area '-1'.

But cube-root of -1 is -1. Does this show that the volume of a cube is negative if the length is negative? Shouldn't it also be imaginary since negative volume is not present in the physical world.
