A New Dimension! Part 1 of n

I want to know God's thoughts...the rest are details - Albert Einstein

I just started reading one of Michio Kaku's books. He started off with the example of fishes in a pond and slowly made me realize how I can conceive the existence of another dimension!

I started blogging right after finishing the 6th page of the book. In that page, he casually mentions about a totally astounding conception - the Kaluza-Klein theory. If you will faint seeing hyper-scientific terms, let me put it this way : In 1921, a mathematician Theodor Kaluza proposed that gravity and electromagnetism could be unified under a single setting of 5 dimensions.

This notion can be imagined like :

Imagine that an object is usually moved only towards left or right. From the object's point of view, if it is raised to a height, it will experience a new dimension. So, all types of movements related to it can be unified under a single setting - three dimensions.


Getting back, the Kaluza-Klein theory had a lot of errors which have been fixed by the modern Superstring theory and a whole lot of others.

We definitely cannot "visualize" another dimension as of now. It has been nearly proven that it is a futile attempt to do so. The reason that not all people are able to imagine an entirely new dimension is because the 3 dimensions or the space which we are familiar with is "intuition" and these 3 dimensions are perfectly visible to us. Till now, I'm one of the "people who cannot imagine a new dimension" but with the hope that some day, I will be able to imagine about a new one...
