Particle Physics - The Secrets of the Universe

Higgs Simulation (c) CERN

This week on the Naked Scientists, we delve into the secrets of the universe to find out what we’re really made of.  Ben Allanach explains how a particle accelerator actually works and what it can tell us about the Big Bang.  Naked Scientist Meera Senthilingam puts on her sunglasses to visit a light source 10 billion times brighter than the sun.  And finally, we’re joined by Cristina Lazzeroni, to discuss her “beautiful” investigations at a subatomic level.

  • 20:41 - The Brightest Diamond; Synchrotron, that is...

    The Diamond Synchrotron creates very high energy electromagnetic radiation (known as synchrotron light) that scientists are using to probe hidden secrets. We sent Meera down to the site this week to find out how it works and the benefits of using such high-energy light.
