Reply to comment by alukyane in There’s just as many numbers between 0 and 1 as there is from 0 to infinity. by Resinate1

We need to know what a limit is. It is the value that some variable approaches but never reaches if one of their parameters approaches a certain point. Example : When X approaches but never quite reaches 0, X^2 approaches but never quite reaches 0. It's the limit of x going to 0 for X^2 . The Limit. A limit implies the constant movement of some variable towards a certain point. So we NEED to talk about X, or a variable of any kind, if we want to calculate a limit. He just said the number 2, a constant number, not a variable, we can't work with it.

The OP speaks relatively while you're speaking absolutely. Maybe you've misunderstood what was said?

At that..you don't freeze frame the universe, that's not how the simulator works. This is same concept as the coastline paradox. It's not just about making everything stop while you grab a tape measurer

That's why it would need to be measured with a standardized tool. You can't take a 5 ft something and a 6 ft something, measure the universe with both and then say that since it takes less 6 ft things than 5 ft things than the universes size is smaller or bigger.

Yes the universe is expanding, but if you pick a point in time, you'd have to measure it with one object to determine it's size based on that object and then you'd be able to define it's size which then wouldn't be any different for the other objects on it. Just because one object perceives the size to be different, doesn't mean that it actually is.
