busy

Totally surprising.. Why am i so busy that i don't seem to have time for myself? There are the library books to read.. Food to cook.. Balls to shoot.. Videogames to play... TV to watch... A week passes like a day..

Nothing much to blog about. Lets talk a bit about the universe.. Hahaha..

Did you know that the universe can actually be finite in volume?

If we accept the fact that the universe does not have to be restricted by three dimensions, then it is certainly probable that the universe can be finite in volume.. To show how this can happen, think of the earth as an analogy. From the ground, Earth looks like a plane (flat), that will stretch forever and ever. However, we know that the earth is finite in area, because it warps around itself in 3 dimensions. Similarly, if the universe exists in 4 dimensions or more, then mathematics permits the universe to wrap upon itself, in 4 or more dimensions. But because the universe is so huge, the fourth dimension is barely detectable by our equipment.. Of course, the human mind is only limited by 3 dimensions, no one can actually "see" a hypercube, but that doesn't mean it does not exist.

In maths, n-dimensional vectors are abstract arrays of numbers. for eg (2 , 3 , 4) is a 3 dimensional point which can be represented on a 3d graph (xyz). There is no way however to represent the point (2 , 5 , -5 , 10), which is a 4 dimensional vector, using an wxyz graph such that it is intuitively intepretable by the human mind.
