Now imagine that it is just a mathematical imagination
Thank you for the compliment. because
With " mathematical Imaginations" is how we understand the workings of the universe, Take "pi" 3.14 ..... for example, it is an abstract human mathematical construct, real in nature only because it is embodied there.
the "it" you referred to here is a
math model of
every part of the universe #3 having moved through time #1 the same length since the beginning BB #4.
"it" really is a model, in mathematics of course, mostly
geometry.
Flat landers never had space , nor energy and matter to begin with
The idea, the model of living in 2 dimensions is a useful image though, to understand, that photons travelling in the membrane #3 arriving like in a
panorama, come from a smaller sphere #8 in/of the past
#2. but
there must have been "energy -- to begin" with, because energy can not be created, is fundamental like time#1.
Two dimensions can never change because there is a dimension missing .
True, pure 2 dimensions would be a Euclid plane that is tangent to the membrane#3. so, while a flatlander can only "see" in her 2 dimensions, her 2 dimensional membrane#3 curves through the first dimension , that is time #1.
Do you assert that "time is missing"? the universe does not expand?
Two dimensions can not evolve . From mathematics to the physical ; Because it can never actually exist ; ever , for infinity .
This model of the universe, reduced to the 2 curved dimensions in membrane #3, is not meant to ever "evolve" into an entity in nature; it merely describes a time related condition. It is an attempt though to illustrate the "evolution from a point in time #4 into the sphere#3 though, allowing the drawing of conclusions about energy, the past#2, the future #1, the 13.8 year "horizon", among others. Plug in a proposition, and see where the model will lead to.
