The 10th dimenssion
For those of you that have read about string theory, you may well know that one of the major outcomes of it is the existence of up to 10 dimensions. We, humans, live and feel in a 3 dimensional world, where any object is made up of length, width and height. We can even perceive an extra one, a 4th dimension that we call time, or duration. From that point on, things become very difficult to imagine, our brain cannot draw a picture anywhere of a 5th dimension, but the theory says that we are just "trapped" in a three dimensional world, just as a King in a playing card could only "see" things in the plane where its eyes sit.
This animation tries to explain the concept visually, and even when the theory does no support this approach, I think it does a good job:

Oh.My.Fucking.God.
No.
I’m trying HARD not to be anal about it, but that video is WRONG.
Oh, Hi Adri, by the way! ^.^
So, the video starts well enough, but by the time it treats time as another dimension it went downhill from there on.
Dimensions can only be conceived in one of two ways: empirically (by Euclian space, that is, through observation, like the greeks did) or mathematically (that would be through Minkowski space). Both types of space definition acknowledge that time does not have space-type properties.
Through Minkowski-Bouligand observation, time is a direct consequence of gravity, and as such, it can be bent through gravitational fields but only as a positively vectorized equations, which discards any and all space-like properties. In Euclian observations time doesn’t even stand as equals to the other dimensions, and cannot be manipulated.
In other words: forget everything you just learned from that video.
It sounds daunting, but it is actually fun and easy to learn once you got the basics right. For that, I recommend Michio Kaku’s excellent introduction to higher dimensions through his book “hyperspace”. I talked about it once in my blog (link here: http://tomypledgedwordamtrue.blogspot.com/2009/05/hyperspace-michio-kaku.html )
If you wish, I can send you a digital copy of the book. Contact me if you crave for more. Be well Adri.

Hey Arc!, thanks very much for the comments, I love your energy on them, I found them incredibly mentoring :). I absolutely read that book, in Spanish though and quite a long a go, but I have it with me here in England, and I could say that you made me start reading it again, just to check the amount of junk that my head has been soaking about this matter since then.
Please, be well two :)
