well kind of,.theres is around 1 molecule of matter per square meter in the void of space,there is friction in space but so small its almost immeasurable.
Well the LHC is the first accelerator of this size,tho not the first accelerator,there is quite a few smaller ones,in Netherlands ,Spain,France and many others all over the world - so they kind of know what there doing,and half know what to expect,.
thing is the particles there dealing with are so small the results will be just as small,in fact so small that the results will be hardly be noticeable let alone measurable- however it is possible that once the experiments start they will get results from experiments IN THE FUTURE !
they are actualy dealing with matter in time & space.,and as thus they theoreticaly could see the results from experiments they do in 30 years from now. honest !
