“An excellent answer mister Tithic! however, it is only exactly true mathematical speaking.”

Lecko activated his holographic projector and the classroom was filled with an illuminated illustration of a three dimensional coordinate system. Two dots appeared.

“In mathematic calculations; the shortest distance truly is a straight line.”

A line appeared between the dots in the hologram.

“But, in real life physics; the nature of space-time actually makes it possible for two points in space to be the same point… it is very complex and you may not accept it as a fact, but it the nature that makes wormhole and R.I.T. travel possible… let me illustrate it.”

The coordinate system disappeared and was replaced by a representation of the space-time: a flat net grid with the two points placed in it.

“This is the closest thing to space-time as I can show it, as it requires understanding of different dimensions to completely understand the nature of space-time. These, are the two points under normal circumstances, and here if they actually are the same point…”

The holographic net twisted so the two points touched each other.

“This is an extremely rare phenomenon in nature, but there are a couple of existing natural wormholes known, mainly such reality bending is artificially created.

Err… did you say something young Ker?”
