Tachyon vs neutron

  1. Feb 27, 2008 #1
    Hey, I am yet to study particle physics or QM but in a few forums i have read that there is a particle called a tachyon which travels faster than the speed of light. I told my mate this and he asked "if you collide a tachyon with say a neutron which is travelling lower than the speed of light what would happen" i.e at some point would they travel the speed of light due to conservation of momentum?

    I obviously couldnt answer him because of the small amount i know about tachyons but i assume that this cannot occur for some reason or other (due to the properties of the tachyon perhaps?)

    Well neither him nor me were satisfied with that answer... Could someone else suggest what might happen?
