There are 2 basic units of measureables in science:
1.MASS which is the amount of matter & implies UNITY. A distinction needs to be made between basic mass and aggregate mass. Scientists today continue to break down mass in search of the snallest basic particle, hence the basic mass. So far they have proven the Higgs Boson to be that particle. Mass is seen as being proof of existence.
2. DISTANCE is the separation between two identifieable masses. It implies an area of space, ie, non-existence. Time is closely related to distance and seen as dependent upon distance. So it is seen as a co-dependent feature of distance.
3. Other units of measure considered to be co-dependent upon the two basic ones:
HEAT
PRESSURE
FORCE
CURRENT
VOLTAGE
ENERGY
etc
I am sure there are others.
But these all resolve to mass and distance.
CONCLUSIONS:
Today there is talk about space as if it were a fabric having mass. I just cant see that.
There is other talk about going back in time.I cannot see that.
There is also talk about multi-dimensions.
Dimensional idemtification is nothing more than arbitrary establishing directional reference.
Multi dimensions may serve a purpose in attempting to describe a reality, but has no reality unto itself.
