Question CYCLIC UNIVERSE

[G_x0a]

I value the preservation of scientific clarity, which will be something that does not need to be written down and will always be respected, from me.

And of course that respect does not come from you, whether I understand you or not, is irrelevant.

Hello Cat
You said no universe.
Please define the Universe.

NASA has assumed the universe is 13.8 billion years old.
And try to work within that scope. Read the following.

Hello Cat

Harry, there are innumerable "observed universes".
What is the total of these?
What about other collections of items including galaxies?
Maybe none are observed?
Then, the total of observed universes is "The Universe"? We do not know.
What if only one star is not observed?
So "The Universe" cannot be defined in any certain (unequivocal) way.

Do you accept that so far?

Hello Cat
Always love your writing.
Good on you.

We are getting into metaphysics/philosophy.

If something cannot be defined, then it does not exist as a "known" object.

You can define "The Universe" as "all there is", but what does this mean?

What do you mean by "is"?
We come back to what does science say "exists"?
Science is based on observation, measurement and deduction.

There must statistically be much that science does not / can not observe . . . . . .
Because too far away, too small, cannot be observed in any way.
Do you say "if cannot be observed, cannot exist"? I think not.
Think about what we discovered by using new methods e.g., IR, UV, X-rays, et cetera.
But if you allow "cannot be observed", then you let in fairies and dragons.

I say, if something cannot be observed/understood, then what are you naming?
If you cannot discuss it, then what are you talking about.
Hence I say that the idea of "The Universe" refers to something unreal.
"The map is not the territory".

Hence, I say that there can only be "observable universes".
But what is not unobservable by us, may be observable by others.
Therefore "The Universe" cannot be defined, and becomes metaphysical.
