A Question of Space and Time

Scenario: Miniature & Parallel Universe
The following question originated at a dinner party among friends. There was an interesting and educational variety of answers. By the readers leave I’ve transferred the question to SciForums.com

Question:
In a universe parallel to ours, exactly the same in every way; with all of the galaxies - including the Milky Way, and our solar system with all our planets as they are, including earth and everything on and within it and including its inhabitants and the molecules and atoms - except...:

that this ‘twin universe’ and all of its contents was one thousand times smaller than the universe we in the here and now occupy - instead of the there & then occupation of the miniaturized universe (including all of our miniaturized selves): would this miniaturized universal space and all of its miniaturized contents undergo and experience the same time standards as the ‘regular sized’ universe we are part of?
Yes or no.

Addendum options
Time would be the same in the two compared universes.
Time would be different in the two compared universes.
If yes, please explain.
If no, please explain.

seriously, like we live in this universe, we have no idea of existence of another life but that on Earth...and here we are thinking of parallel universes...
no I believe we can create another universe within ours, so that their universe runs almost forever and in our world it takes only a second. And they can create their own world...and thats how worlds are created. But all this is just thin air, as it has no value (for now).

Would space be subject to the same constriction?

Would the speed of things be the same?

***********************

Dear Prince James:

In the proposed circumstances, your two thoughtful and timely responses are part of the proposed question(s).

Comparatively speaking, the smaller of the two parallel universes would not experience any more 'constriction' that that which is experienced in the proposed universe of the here and now as we know it. The space would be smaller and denser in the smaller universe, only when compared to the relatively large and tenuous universe of here and now.

'Would the speed of things be the same?'

Indeed, that is an integral part of the proposed question of whether or not (the measurement of) time would be the same.

May we designate the smaller Universe as A, and the comparatively larger universe as B. Would a square mile in Universe A be the same size as a square mile in universe B?
In accordance with the stipulations of this thought problem, the answer to that question is that the square mile in universe A would be comparatively a thousand times smaller than a square mile in Universe B.

The issue of speed is introduced in consideration of what, say, 60 mph is, in A universe; as compared to 60 mph in B universe. It appears that the 60 mph in the larger B universe would be comparatively much faster. On the other hand, perhaps you may perceive these issues differently.

May this response further focus and clarify the proposed circumstances for whomever wishes to draw and share their own conclusions.
 
A Question of Space & Time (continued II)

Mass would be scaled. All molecules, atoms, electrons, nuclei, photons, spectral lines, erg seconds, black body radiation, particles, waveicles, hydrogen atoms would be one thousand times smaller in (smaller) universe A.

Smaller Universe A would be more dense (constricted?) only when compared to larger Universe B. The inhabitants of smaller universe A would perceive reality and all of its contingencies - certainly including space-time - the same as the inhabitants of larger Universe B. In this setting, the inhabitants of the two issued small and large universes would be unable to observe or compare - though they may optionally be aware or unaware of - their parallel realities (as described here).
