Who am I?

I am found at the time stars collapse. I require high temperature and high pressure. I am similar to the Higgs Boson and am one of the simplest particles, with no charge. CERN physicists want to create me. My existence relies on a new theory of gravity, known as the quantum gravity theory. If I exist, I will help explain supernova explosions and the production of cosmic rays.

NASA's amazing Astronomy Photo of the Day yesterday showed a solar filament erupting into space. The eruption at the end of last month released electrons and ions into the Solar System - some of which arrived at Earth three days later causing stunning aurorae, such as the Northern Lights.
