Limitless universe
#13
Mainstream model for the universe is expanding time-space. It follows from the GR and the fact that the galaxies are moving away from each others.

The presupposions, axioms of GR are three dimensional space and time as the 4. dimension. In non euklidian analytical geometry.

I dont know how long the axies, the vectors are supposed to be there and if the time dimension is similar as the others. 

It must have something to do with the friedmans mathematics.

If we put in the axioms a lenght of x (90 billion light years for example) and time as different dimension, as eternal or a zero, or moving just forward and not backward, as it really is for the whole universe. Because the universe is not a moving particle and it has not outside, what will we have there?

We dont know how long the vectors are, and we know that time is not similar dimension as the others.

It means that the distances between the galaxies, as measured with our rulers, increase.  

This could be explained by some expansion, but as well by shrinking rulers.

What is shrinking rulers?
