That's the definition of a ring or loop.

Take a line and join the ends. done.

Take a class on Topology if you really want to study spaces like this.

it is a never ending line.

You've made a straight loop.
If you put the portals next to each other it would be a still be a loop, it would just look more like one.

never ending line?!

I can see the ends right there by the knot.

Even if you smoothed out the knot, there's still finite rope.

A loop is defined as a line segment with its ends joined.

a circle is a loop of constant curvature. so under these lax definitions, that is indeed a circle. curvature zero however, implies infinite radius, haha.

You know, if the portals were vertical, this rope could cut DIAMONDS.

Concepts of lines and circles are euclidean geometry.

In order to accurately describe the varies portal experiments, we are talking about totally non-euclidean geometry; we're gonna need a new / bigger lexicon to describe the new stuff.

It's hardly mind boggling; new science, new words.

This is all.

if you put the two portals on a sort of movable wall (like a chalk board on wheels from 3rd grade) and pushed the two boards apart, would the rope stay tied, and thus increase in length? if not, what would happen

Topology sounds really cool. How would you rate it compared to, say, differential geometry?

Anything you want to happen.

Assuming the existence of portals already breaks the conservation of energy and momentum. Once you've done that, you can literally do anything you want and back it up with math.

But naively, the rope would experience a force stretching it (equally at all points). Somewhere it would be weaker and that would stretch more, then eventually break.

If you smooth out (or ignore) the knot [layman's term], you have a knot [mathematician's term], or an embedding of a circle in a higher dimensional space.

>> No.1133725

Basically because they mean that changes of momenta/energy/force/etc with regard to displacement are discontinuous. They break the light-speed barrier and allow paradoxes. And I'm pretty sure that to have any sensible results from them you have to avoid relativity.

As an obvious example, put them vertically with a water wheel in between. Pour a bucket of water into the bottom one. There, easy infinite energy.

Put one at the bottom of the ocean and one at the top of a mountain... instant river. Put one in space and one on the ground and you can get to orbit as easily as falling into a hole. You get the picture.
