we are[[?]] really three dimensional and this [[?]] see the curve which is in the direction of the third dimension. If we were two dimensional beings we could not conceive of the third dimension and thus could perceive no curves.
It is really that way with us [[?]] [[?]] three dimensional and can conceive of no other[[?]] in the direction of the fourth. Thus, the universe seems to us unbounded in every direction although really, when you go in enough [[?]] [[?]] right back to the starting point. And that is what is meant by infinite and bounded. The universe possesses a definite volume just as the surface of the earth has a definite area, but travel as far as you want you can't[[?]] reach the end of it.
The cry[[?]] [[theory?]] is raised: What is beyond the universe? If it has a limited volume, there must be something occupying the rest of the Cosmos. But there really is no beyond. The universe is total, complete. There is no continuance of the plane of the earth. It curves back upon itself and leaves no place to hook another plane on.
But there are other planets. Yes.However, in order to reach them you must travel in a direction,k perpendicular to the plane of the earth's surface. A flatlander could not conceive of this.
There may be other universes in the Cosmos, but in order to reach them one must travel in a direction perpendicular to all three axes of our surface. This direction is called the fourth dimension, and it is this motion which authors speak about when mentioning "Travel into the fourth dimension." This quotation has no meaning, as a dimension taken alone is not a space into which one can travel[[?]] but by moving in one direction on[[?]] a[[?]]
