Imagining the tenth dimension
Life in Athens goes on, calmly, and we only notice the upcoming winter because of the shorter days. It's just 5.30 pm and the Sun already set. Besides that, it's 25 ºC outside, perfect weather to enjoy a frappé in a terrace.
Since it's already november, I decided that it was time enough to write a new post. And today I remembered a very good video explaining the String theory for 'all the audiences', meaning that you can get at least the background of the whole issue without being a quantum physicist.
It takes a lot of imagination to think of the tenth dimension. The first part of the video is 'more or less OK', the concept of time as the 4th dimension is already a very old idea (even H. G. Wells wrote about it in his Time Machine).
But things get somehow twisted in the second part, when we have to picture the infinity (and that means just everything, all the possible timelines of our Universe from the beginning to all its possible endings) as a single point in the 7th dimension, in which there are more possible points and connections among them, possible splits (8th dimension) and possible folds (9th dimension).
So, open your minds and enjoy!
