douchebag semantics >.<
I hope you're enjoying yourself :P

>mfw englisch speaking people pronounce Einstein. The "st" doesn't sound like the one in "star", but is a composed term, like eu in Euler. Same goes for ei, sch, sp, äu, ...

How do you say Grothendieck?

>I know I'm not using accurate mathematical terms
the expression "Euclidian geometry" would be a start.

>every non-euclidic geometry
geometry of induced objects in low dimensional (say 3 dimension) Euclidan space is not the only type of geometry, see the first list here
http://en.wikipedia.org/wiki/List_of_geometry_topics
so non-Euclidean is not very specific.
If you consider (induced) Riemannian geometries
http://en.wikipedia.org/wiki/Riemannian_geometry
and the metric is somehow restricted (Globally Lipschitz continous for some (small) constant seems reasonable, i.e. the measure of distance doesn't change too much)
then if you soom in, it will look very Euclidean even on a finite Area. Riemann geometry also looks Euclidean in a single point, but that's not very helpfull.

>the biggest triangle in the universe
If triangles exist at all is a quite philosophical question. But I'll just assume we are talking of any three points in space here.
>through curvature of space
since gravity exist, it this is true in any case. You'd naturally define the lines connection the three dot's in space using a path light goes and this path is not straight due to gravity.

>that a proof, that our universe is not infinite large
no, in general relativity, that's all pretty unrelated to the properties far away from us.

why don't you just post the link, just one pic of it??
