jazzy_daveDownloaded and watched a couple of Horizon programmes during the week and both looking at the universe from asking how big the universe is to how small the universe is. The first programme looked at the large scale of the universe and attempted to answer the mind-boggling fact that we may not be the only universe and that we live in a multiverse. These other universes being in their own bubbles and impervious to our senses.
The other programme looked at the universe on the small scale from the initial big bang and attempted to answer what is the smallest constituent of matter. What are the fundamental particles? Is the quark the most fundamental , and if not what strange vibrations make up the quark. This has lead to the idea of string theory that all the fundamental particles are just tightly wound strings of different vibrations. And then perhaps there is a limit to how small things can get, the so called Planck length. Nothing can be smaller than this Planck length.
Fascinating, mind-boggling, exciting and just the kind of science programme I love to watch.
