Just take the three space dimensions. If length, width and height are all relative no objective measurement is possible. You would have to define one as absolute and use that one to measure the others.
If everything is relative, you have "nothing to stand" on so to speak.

Isn't measurement always relative? I mean, we could use my laptop's width as a unit of length to measure objects at any scale (I know, not a particularly reliable measure). The unit of length is really arbitrary isn't it?

Is there a relationship between scale and time? Does time slow down, for example, at larger scales?
Also, Tom, your suggestion that our sun might be a proton in a larger scale (or that protons in our scale might be suns in smaller scales) is just a metaphor, right? Unless I'm not understanding something, the difference in size between our sun and a proton doesn't seem large enough for this to be the case. It is more likley that our sun, in larger scales, correlates with particles much smaller than a proton.
Or am I not understanding sub-atomic distances and their relationship with astronomical distances?

Actually, time and scale are independent dimensions. But in MM, time is not some physical thing. It is just a measure of change. And on larger scales, change occurs more slowly than on smaller scales. So time seems to pass more slowly.
