large spaces or not this is confusing , explain the difference between expanding and creating new space. if expanding space only affects large space , why does light / photons have redshift?

i agree with you gonelli. if i draw a continous line on a balloon, and then i blow it up further. The distance between its ends has increased , and new points on the balloon ie "space" has emerged between the ink, which were not there origionally. This is my interpretation .

this is confusing , explain the difference between expanding and creating new space. a. We know that the distance between two points has increased. You say space is expanding ( similair to stretching ?) I.E no " new space being created". Is this correct? If so then everything occupying that space is stretching as well. So then the object that we measure this distance with , will stretch in proportion to. Then the ratio would stay the same. The how can we observe "a" above.

Are there certian postulated math axioms, that cannot be proven. Do these axioms ( if they exist) , constitute the basis of all mathematics. If so where can i get more info?

If space is being created with the expanding universe, can it be destroyed as well.
