My question is silly formulated, but I want to know if there is some sensible physical question buried in it:
Suppose an exact copy of our universe is made, but where spatial distances and sizes are twice as large relative to ours. Would this universe evolve and function just as ours?
Since mass is proportional to volume which is distance cubed, but strength of a rope is only distance squared so it would not work in proportion.
Does this mean that a universe with our physical laws that evloves like ours can only have 1 certain size ? Or would the physical laws scale in proportion so it evolves the same ?
How can it only have 1 size, what is it relative to ?
Also, suppose another exact copy of our universe is made, but where everything happends twice as fast relative to ours, would it evolve in the same way as ours? (We can suppose if needed that our universe is deterministic)
