Did anyone else see Horizon last night on BBC Four?
http://www.bbc.co.uk/programmes/b006mgxfIt was absolutely fascinating in it's look into the research going on to establish how small our universe is. That is studying the smallest objects of the universe, atoms. If you, like me, are very interested in quantum physics this was the programme to watch. Only over the last ten years have scientist been able to actually see atoms, but now new instruments are magnifying these by billionths and can study individual atoms. They are fascinating 'things' that form everything we know and have parts in turn being investigated to see how they relate to the main neutron of the atom. But it is the fact that scientist believe there are even smaller bodies in the universe than the atom, with theories of a fourth or even fifth dimension due to the special nature of their existence and form; wonderful stuff!
Once again I have now heard from a scientist about the tremendous, ground breaking, revaluation, revealed by using the
Magic Telescope (
http://magic.mppmu.mpg.de/ ) which captures gamma ray blasts caused by colliding stars or collapsing black holes. It is that again scientist have detected the possibility that the speed of light varies, with shortly after the telescope opened it detected a gamma ray burst that although transpiring at the same time took 5 seconds from beginning to end for the detectors to receive, thus meaning each part of the gamma ray burst travelled at different light speeds.
The Large Hadron Collider (LHC) of CERN (
http://public.web.cern.ch/public/en/lhc/lhc-en.html) two years ago also detected during one of it's experiments part of an atom, neutrinos, travelling faster than light.
This all suggests the rules of physics may have to be redrawn as light may vary in speed and individual parts of atoms that form all things on earth may be able to travel faster than the speed of light. The possibilities if that is true are endless.
As I always say "We know nothing yet!"
