Two people were quite definite that the discovery of the Higgs particle at CERN was a major story.
I had decided not to put that one in on the grounds that it was a particle physics discovery, not an astronomy one. But, in fact, particle physics and cosmology come together at the beginning of the universe. The Higgs field is what gives particles mass, so the fact that we even exist is related to this particle.
There was a forum discussion about this in July 2012, What is a Higgs boson? Explained with zombies
- it includes a link to an explanation of the Higgs particle with zombies. Amusing and helpful.
