A particle facility will measure the myriad of smaller particles and form a detailed map of the initial collision. Much like taking an object made of glass and smashing it taking a series of pictures of the bits and their trajectories.

At no stage is there a visual of the actual collision. The atmospheric collisions at many millions of times the individual energies offers the chance to view the actual collision. Additionally it can be viewed in a variety of frequencies just as in stellar astronomy.

I am not anti trying to know what it all means, I would just choose different and more natural means of measuring. I am very much against CERN and operating the LHC at a combined collective energy of millions of times the second per second energy is not a path I would choose or recommend ... ever.
