Is infinity unreal? We talk about infinite space or an infinite number of real numbers between 0 and 1 a sort of endless division by 2 or whatever. But I wonder how real Infinite actually is.

  • Take an infinite line and join the ends. Is it a finite circle? Or is it an infinitely expanding circle?
  • How about the real numbers between 0 and 1. If you integrate from 0 to 1 you get 1. Is that like joining the ends?
  • And, even if the universe is closed (as opposed to an infinite flat Euclidian one) can it expand infinitely?
It seems as if there is a resolution (like joining the ends) but more profound. As if there is something more fundamental than 'joining the ends'
I cannot crack it. Anyone?
If a line is infinite it has no ends to join. No matter how far you go you will never find an end.

"Is infinity unreal?"

"Infinite" seems to depend on definition. As you note, math is something which can have infinite aspects, which includes the line in a circle. But these are abstractions. What about "real" things, like what humans see or imagine to be real?

Like cosmology.

Most "experts" in cosmology suggest that the Universe is on an endless expansion from the BB. and will continue to expand as it approaches heat death. This might expand space infinitely since some of those same cosmologists tell us that heat death is never totally reached, so that might offer a case for an infinite, theoretically of course.

And there is the rub...........How will we ever know if we have all the details to draw any such conclusion?

I enjoy the thoughts of infinity. Perhaps infinity is possible with chemistry we do not understand like universal weather that repeats itself. Or a repetitive equation of chemistry and gravity.

I personally believe there was never nothing. I have trouble grasping any flux without something existing. I choose the easy way to know that we exist and as much as I like to wonder why we exist it is not very beneficial now days. But if I chose a belief something always existed maybe not intelligent but mass existed.

I’m neutral on whether or not a god exists I’m pretty dam certain we evolve but when you believe in infinity you start to wonder what could be out there.
 
Per the collapsed cosmological constant (/\) Planck heat of ('1' ('Unity')) in superposition Horizon of Universe (U) there never was, nor never will ever be, any heat death of the universe. Per Newton, entropy is always to the middle between extremes. The middle, the center, just happens to be Hawking's "life zone" of universes.

Planck heat is a radiation of heat. So is the equal but opposite radiation of cold, a radiation . . . for one to exist, the other must equally exist (+|-):

On the order of:
=================
=================

Dipole . . . monopole.

"Science begets knowledge, opinion ignorance.
Our abstraction of an external reality is within.

Cat :)

Is there an external reality?

Only a sum total of all external (observable), based on all modes of abstraction throughout the 'Universe'.

Such a totality is unknowable to any combination of abstraction modes.

So, effectively, there is no knowable external reality.
