When I say universe I mean everything and when I say everything I mean the universe.
How can one measure the everything? regardless of if the everything is infinite or not, if it is the everything then there is nothing outside of it, technically non-exisence, not even a complete vacuum, is out side of it so long as those are things. When you use measurements to asses the size of something we relivate the size to something else. For example we say an apple is say 3 inches accross and an inch is specified by light somehow, all of these things are in the everything. So to measure the everything with inches would seem like measureing an apple by saying it is 50 50ths of itself. Ultimately that just tells you that the apple or in the case of the everything is 1. But it doesn’t say 1 what. it could be 1 infinitiy, 1 nothing, 1 everything, so ultimately unless you relavate the everything to something outside of itself you can’t assert its size, the size is undefined, indeterminate, for there is nothing out side of the everything to relavate the size to. What do you think?
I think you meant to use the word “relate” where you used “relavate”. What does that even mean?
This OP is mostly nonsense. I don’t mean that to be rude at all, but it’s the truth. Who ever said that we have the capability to measure “everything”? Saying that the universe is “infinite” basically means it can’t be measured. You say, “…regardless of whether the universe is infinite or not…” and then go on to talk about measuring it? That doesn’t make any sense.
Or perhaps I’m completely misunderstanding your question.
A measurement is merely a comparison of two things.
All size and distance measurements come from the propagation speed of affect or “light”. And since existence IS affect, by relating the relative speed of light to any proposed volume, that volume can be measured.
My point is that people assert the size of the universe before the big bang and after the big bang, but if that was everything, if the universe is everything, then it contains even ligth, and i still fail to see how you can use a part of something to measure that same something. Like I said how do you say that an apple is 50 50ths of itself and really mean anything by it, as 50/50 = 1?
Okay so…
Divide your apple into fifty pieces, then give one to your friend and tell them they have 1/50th of an apple. They would quickly be able to tell you how big the apple was before you cut it into pieces.
How big?
The size of an apple 
Which is to say one apple, which indicates that all we can determine about the size of the universe or everything is that it is one everything. Which I thik was my point.
Okay, that was sarcasm. Guess you missed it.
come on, we just dont know these things…
exactly
Did you miss this part;
Every measurement is only proposed so as to tell you how big one thing is compared to something else more familiar or standard.
If the size of the Sun were something with which everyone was very familiar, the sizes of other things would be compared to the Sun. Likewise the weight of your car might be compared to that of 1/50th of an apple.
Measurement has no other meaning. That is why we have relativity.
Exactly, so because the “everything” is everything and thus there is no “thing” outside of it there is no thing to say it has a size relative too. Thus the actual size of the universe is indefinite, undetermined, undefined. Although i guess one could assert that it is not infinitly small or nothing, as such it could maybe be said to be infinitly bigger then that which is outside of it because that which is outside of it is no thing or effectively the infinitly small…
Why are you trying to compare it to something “outside of everything”?
It does seem rather illogical, maybe a bit of imaginary logic 
like imaginary numbers… in an attempt to actually assert some sort of size. of course even if you did say it is infinite, you could argue that such is not really a “size”…
Here’s my twopennyworth:
Good.
Simple. By comparing it with the size of something in it.
No problem. So we’re trying to measure the size of space, and there is no space beyond it.
Sure there’s no absolute measure because you calibrate your measurements on something convenient, but you can still then measure something and get a good idea of how big it is.
Imagine that you’re a fish living in a big globe of water. You could measure the size of the globe using sound waves which undergo total internal refelction at the boundary. You know how fast they move, you’ve got a clock, and you wait for the echo. The universe is said to be “flat” on a large scale, with no overall curvature to make light waves travel in curved lines, so they just go straight. So think of it as something like the globe of water, where you can do something similar with light. There’s no big conceptual problem here. The problem comes because the universe is thought to be expanding, so your light wave never catches up with the “edge” and never bounces back. But even so, you can think of the universe as being something finite with some particular size at this point in its evolution.
Well a fish bowl, or big globe of water, isn’t exactly the best example unless you suppose the globe has nothing beyond it, no sound exists else where. And you say, “The problem comes because the universe is thought to be expanding, so your light wave never catches up with the “edge” and never bounces back. But even so, you can think of the universe as being something finite with some particular size at this point in its evolution.” What this signifies to me is that we only guess it is finite but actually havn’t found any evidence of that, we just suppose that it is even though we can’t actually assert the size when it is just as lkely that it goes on forever, or after some point mass stops existing but a complete vacuum starts or something.
And back to the fish globe problem, because you don’t know wether there is something beyond the globe, or in our case the universe, you can’t know that what is beyond the universe is simply something or some sort of light/sound sltering thing that would only make sound/light seem to reflect…
The thing is, we haven’t found any evidence that it’s infinite either.
You’re right, I can’t know. But it’s fun thinking about it.
TNote that you said the universe is everything. If it is something like that fish globe, there isn’t any space beyond it. There is no beyond it.
