Thoughts on the scale of the universe?

Zeno...........paradox.........
Any thoughts?

None is merited. I know basic calculus.

For fuck's sake. Are you seriously suggesting that an adult human being in the 21st century doesn't understand the significance of the Cosmic Mircrowave Background Radiation (clue: the universe isn't infinitely large)?

Natural facts are not dependent on human opinion.

Uhhh, CMB only says the portion of universe visible at the current moment isn't infinitely large. It also implicitly says the if the CMB doesn't suddenly blink out during the next moment, then the actual universe must be bigger than the portion observable at this moment. But CMB does not says anything about just how much bigger the universe is compare to that which is visible to you at this moment.

Inflation theory, on the other hand, does say the whole universe must be vastly bigger than what can be seen by the bubble of visible CMB, probably bay many orders of magnitude. But it does not say the universe must be infinite.

One of the new twists introduced into cosmology over the last few years is the concept of dark energy. There are two possibilities of how dark energy could behave. The first is dark energy is a constant in space and time - Einstein's universal constant. The second is dark energy can vary with space and time - Physicists call this quintessence.

If the quintessence interpretation is correct, then that means the true shape of the cosmos, even in principle, can't be determined by looking at its geometry in the observable space.
