Cern collider: Your questions

On Wednesday the Large Hadron Collider (LHC) will send out a full particle beam, in preparation for an experiment that will re-create conditions just after the Big Bang.

The LHC will smash two beams of particles head-on at super-fast speeds. Scientists from Cern - the European organisation for nuclear research - hope to see new particles in the debris of these collisions.

There have been concerns that the experiment could open black holes that would swell in size and swallow up the Earth, but physicists stress that the planet is not under threat.

The BBC is asking readers to send in their questions about the Cern collider, to be put to a panel of experts.

Are you worried about the Cern collider? What questions would you ask the scientists about the experiment? What could this experiment achieve?
