Visualising Gravity

Yesterday, on the Integral Pod, I saw a posting by Tely about ‘Imagining the tenth dimension'. I immediately watched it because I love this kind of video's, where people try to explain things like the universe, gravity, dimensions, particles, speed of light, the big bang, dark matter, black holes and all else, to people like me, who would have no idea how to get such understanding otherwise. 

So I have been watching this kind of video's often these last years, most of all Brian Green's ‘Elegant universe'. For me it is the best way to learn to understand such difficult principles, because he makes it very visible. At some points he goes a bit to far, but as a whole I so much enjoyed the series, which can be seen here.

The part I have watched the most, is chapter 3 from part 1. It is called ‘A new picture of gravity'. Here he makes visible how Einstein thought gravity works. I never could understand how that was supposed to work and suddenly, while watching the movie, I kind of understood it.

Also the part ‘Gravity the odd man out' I found very interesting. There he explains the search for a unified theory. Of how the strong nuclear force, the weak nuclear force, electro-magnetism and gravity should come together in one simple equation.

Of course the overall goal of the movie is to talk about String theory, and that may or may not be a valid theory. But for me it was an amazing opportunity to see how, at this point in time, they think the universe works.
