Thank you Chelle :) shall get onto it now :thumbup:

10^20 eV particle hitting a stationary target makes as energetic collision as two 10^10 eV particles colliding head-on - so in fact to be accurate it is necessary to look for such high energy particles to be able to see effects of what's going to happen in LHC happening naturally in our neighborhood.
There sure are not too many of them but there are enough to be reasonably certain that even head-on collisions of two such particles happen occasionally somewhere in the space.
I was doing some catching up by reading Don Lincoln's book The Quantum Frontier: The Large Hadron Collider

And encountered this information (p.93-94-95) regarding frequencies of collisions: 800 million collisions per second for 10 to 20 hours, and energies that supposedly 'don't need to be that energetic' are in the case of Lead collisions: 575 trillion electron volts per nucleus.

Apart of the beam energy which is halved per particle and fraction per beam compared to design values, I don't see anything that hasn't been in LHC design report for a few years already.
