I'm with you on some of that... At differing time and space scales there are different qualities of importance. (different things we can effectively neglect)

So what is going on at a universal scale might not at all be obvious to us. We automatically neglect it because we can't see enough information.. The assumption a scientist would make is the simplest one first - they originally imagined a stationary universe, then the evidence came in the it was expanding (hence the big bang theory, expanding from what?) but they assuming the simplest expansion model first - or at least a constant deceleration based on gravity... This too was wrong...

More data coming in still leaves us with very limited ideas of the universe on these scales. How and ever, we're getting better all the time.

On my niggling disagreement - we can understand the concept of infinity. There are specific infinities which we can deal with (and resolve to make sense of within quantum mechanics) and specific infinities in general relativity which we know our current model doesn't handle... That they model doesn't describe them... We know where we have infinities how to deal with them and what they mean - usually they mean our model is wrong because we see no infinities in reality, only in mathematical models...

Yes, but I feel thats more like we can "observe" infinity rather than comprehend it. It's like the fact that we know the ocean is there, but we have no idea how deep it is or what lies beneath its surface at some points.

What things like Pi though? Is this considered an error? I'm genuinely asking. And what of the idea of the universe expanding on forever? Where's it expanding through if that's true? What's outside "everything"? That is a concept we can think of it existing, but we have no idea exactly how it works. This is utter infinity.

Pi is just tue circle ratio, we can calculate it to a far higher degree than we can ever physically measure it. On some scales space no longer appears discrete so circles... well any physical circle will be an approximation in the first place, if we imagine a circle running in space (and we approximate that space as flat) eventually we will be measuring it below the plank lenght where distances are no longer meaningful (due to quantum mechanics)

Circles are thus mathematical constructs which don't exist in reality. Pi is just the circle ratio which is an idea we can express, and fundamental to the idea of flat 2 space (ie Euclidean Geometry) is that circles have a ratio of cirumfrence to diameter of a number i shall define as Tau/2

It's an idea, and we can comprehend the idea of Pi being infinite and non-repeating without necessarily knowing more the three digits of Pi.

The idea of space expanding forever is a though one. It kinda depends a lot one the global geometry of the Universe, is the Universe simply connected? Could you continue travelling through space and eventually return to your original position? (like on the surface of an expanding balloon?) if we imagine the Universe is like an expanding surface embedded in a 3 space but infact a 3 space embedded in a 4 superspace, then that implies the existance of another spatical dimension and some constraint holding us in this space... But we can also imagine it to be a 3 curved space not embedded in anything, and the black hole cause so much curvature they essentially create one-way loops, inside the loop there is no way back...

We have theories of Multi-dimensional (meme)Branes, which would have universes sitting on them and as they spread apart they would drag the expansion of that universe, or as they collided with each other thet would cause a big bang type event. But these theories have no testable basis, thus we can gather no evidence for or against them (at present)

In a more classic sense, we would imagine the 3 space we live in expanding not into anything. Just streching itself. Space is just a measure, it doesn't need to expand into anyfhing, and expanding forever will always still remain finite in a finite amount of time (if space is finite to being with, and again we don't know anything about the Universe's global geometry, it could be toroidal, it could be infinite, it could be saddle shaped..)

I see where you're coming from. And let me just say I find very coincidental that you mentioned the perspective of circles just then. Just other day, I made a topic online about a thought I had been dwelling on a few days: The idea of the circle not existing except in certain perspectives. As you get closer up or further away from a "circle" it begins to focus and blur respectively, changing its shape effectively. Even though it doesn't "exist" though, it seems to be a building block of humanity. I got the idea from watching that movie K-Pax years ago. Cells, to bubbles, to planets, to suns, etc. Plays into the idea of everything working on perspective and all things being connected by a single large design we can only see a corner of. I watched a video (Imagining the 10th Dimension) once that basically explained how the universe and its dimensions are (theoretically) made up of points and lines and the spaces between them, the "points" being a circle maybe you could say.

If the universe was just stretching, it would seem to me that time itself would slow down or something if my basic knowledge is correct? Or at least leave larger and larger gaps of "dead space". I've thought on black holes as well, the way they are constructed it seems that gravity is pulling everything to a single infinitesimal point (maybe one of those starting "points" of a dimension?). Where it goes, we don't know. Let me offer an extremely out there idea: Think of trenches in the sea. What is their purpose? Think of that with some of the things I have mentioned beforehand. I'd rather throw some ideas out there than think they have no purpose. Everything in the universe has something it's balancing out.

"Jesus loves me, this I know. Because the Bible tells me so." What part of this are you finding hard to understand? Repent or burn, sinner.

When I think of science and quantum physics my brain hurts and because I struggle with concepts like existence, creation and infinity I'll got a simple answer. God created everything and is still responsible for everything ...... ah, that feels better I can go back to being a lazy ignorant fool now, and it feels nice 'cos now I have all the answers, how smug am I !!

pretty damn smug, but I was enjoying the mere humor of the statement :)

Science has it's uses and so do Gods and Deities
@ Yellowjacket..which Bible sayeth that,where.
The Bible of the Church of Latter Day Saints is a rather fanciful, but dull affair (so far )
is it that one ???

"jesus loves the little children, all the children of the world,
red and yellow, black and white, they are precious in his sight,
jesus loves the little children of the world.."

Besides all I have said sounding so cold and logical, I still wanted to reiterate I believe in some sort of higher power. Though I am not religious, if you pay attention, almost all major religions follow similar goals. Don't kill out hatred, don't steal, be good to your people, etc. It's like to me all religions are just cultural interpretations of the actual root idea. You can't tell me stories and ideas don't evolve over hundreds let alone thousands of years. It's just that your relationship with "God" should be personal I feel, rather than a printer-press idea shoved down one's throat from birth. When you are forced to an idea and can't find the answer, you shun it, but when curiosity makes you keep going, it's all the more rewarding to find the answers for yourself.
