Pi is a lie?

long live tau.

But more seriously, what is the length of the hypotenuse of a right angle triangle with 2 sides of length 1. Oh look, you can have irrational lengths.

[chamber]

Alternatively, irrational just means the number can't be defined with fractions of whole numbers. It says nothing about geometric space.

poor sod

Lol because irrational distances don't make logical sense in the real world, only in the ideal mathematical world

no, they still make sense even in the real world.

[chamber]

Right, what who said is fine. I don't think that's what you meant though given that you specified irrational distances. Irrational distances make as much sense as any non-zero distance.

[chamber]

My statements aren't contradictory.

[chamber]

You have to assume that I'm talking with perfect precision and no context to take them as contradictory. It's obvious to me that no measured value is accurate in practice, irrational or rational. But the bases of this thread was you having a deep misunderstanding about irrational numbers that I feel you still possess. In my first statement what I was trying to get across was that there was no divide between irrational or rational numbers in that sense. I believe that was a reasonable way for me to read what you said given that you were still specifying irrational numbers. If it's not what you meant you could have stated as much, if not when I said it, now. Instead you are trying to shift blame onto me when no blame needs to even exist.

[chamber]

just a rational approximation to whatever the real length is

Questioning things is fine. Questioning them only because they don't conform to your common sense isn't. That's the real trap Einstein fell into.

[chamber]

I mean, my common sense agrees with Einsteins when it comes to quantum mechanics so~.

Imagine the surface of a sphere. Go to any point on the sphere, but you will never reach the end. The sphere is finite but has no end, just like the universe.

Although not disproven, the hypersphere would need to be unbelievably large. space in the observable universe is effectively flat.
