Brain Food IV AND V

Also known in some cultures as Food for Thought! Bonus snack day.

People say that the universe is curved. This is often called one of the most beautiful true statements ever thought up. If it is true, then that means that both space and time are curved. One of the most interesting things things about a curve is the fact that, in order to be a curve, a curve must have no lines in it. Since a line is made of infinite points between two specific points, and as a curve has no lines, it cannot have infinite points between those two points. However, as the universe curves back into itself, if you were to go in one direction for a extended period of time, that is to say, if you went in a straight line, you would eventually return to that point. In other words, while the universe isn't infinite, the space inside the universe is.
What explanation can there be? Since there cannot be a line in the curve of the universe, and yet if you go in a line in one direction, you will return to your original location, one can only assume that there is only one point to begin with. In other words, there is no space - just a single dot on a piece of graphing paper.

And, as todays special bonus, we'll take it a bit further. We have been talking exclusively of space. The universe, however, is made of spacetime, so what we stated before about space must also be true about time. In other words, there is only one point of time. Therefore, it can't have been almost nine months since my last post, because there is only the now, and never any other time!
