True, however: "Experiments using the technique of colliding high-energy particles with opposing speeds create conditions on Earth different from natural collisions due to cosmic rays. Heavy particles created by cosmic ray collisions with the Earth, if they are not strongly reactive, will retain significant speed and will pass through the Earth to be lost in space. Conversely heavy particles generated by colliders (like RHIC or LHC) using the technique of colliding high-energy particles with opposite speed, have a very slow speed in relation to the Earth and these heavy particles could then be captured by Earth’s gravity." http://www.risk-evaluation-forum.org/anon10.htm T
