We are just strings of quarks living in a suburb of the local density maximum of the universe.
Supersymmetry is a theory which stipulates that for every known particle there should be a partner particle. For instance, the electron should be paired with a supersymmetric 'selectron,' quarks ought to have 'squark' partners, and so on.
Where nature goes to create stars, galaxies, quarks and leptons, you and I also go to create ourselves.
What of course I would like to be writing is the story of the Red and White Dwarves and their Remembering Mirror, their space rocket (powered by anti-gravity), their attendant entities Hadron, Gluon, Pion, Lepton, and Muon, and the Charmed Quarks and the Coloured Quarks. But we can't all be physicists.
The top quark was discovered in 1995 and since then the Higgs has become an because the standard model was incomplete with out it.
