Ever wondered if there was someone sitting next to you and you did not even know. We live in a three-dimensional world where every visual object is represented by an X, Y and Z coordinate. There have also been arguments on a fourth coordinate "time", based on which your other three coordinates can change.
Have you ever wondered why only three coordinates? Does the theory of an n dimensional universe hold water? We the humans are on the ever-growing lookout for aliens, organisms from other worlds. Are we looking in the right direction? What if we cannot sense them? They could be living right with us but on a different dimension. This has been beautifully explained in Michael Crichton's Sphere, one of my all time favorite books.
Recently, some astrophysicists have discovered up to 6 dimensions. They are basing this claim on the fact that there is some invisible dark matter that is having a gravitational affect on stars. 85% of the mass of the universe accounts for this dark matter. This invisible dark matter could be something visible on a different dimension. More on the article here.

N-dimensional space!!!
Man, i have trouble keeping track of the three already. Some people can never be satisfied can they.
There is a famous example in AI called the "hyper apple". Seems that as the dimensions increase, the 99.999% of the volume of the apple would be on the peel!. Crazy!!..
In my algorithms class (MS), the professor tried to draw a 4 dimensional cube to explain some concept. I still cannot get the concept or the cube!.
Interesting !!!
and Humans think they know all ..
I am reading this book about a planet "Yargo" not in our solar system!
It's kind of strange, what could be going on! You never know!
