LHC experiments shed light on why matter dominates over anti-matter

[gary]

Why is there so little naturally occurring anti-matter in the universe?

Physicists have run experiments using CERN's Large Hadron Collider
that have taken us a step closer to answering that question.

Wow, that's big! A fundamental question of physics. Would be good if this is true.

I always wondered how and where they store all this critical data recorded over the years. I assume they'd have it duplicated in many different geographic locations as well?

Hi Marc,

According to the CERN web site, they are producing about 75 petabytes
(which is 75,000 terabytes) of data from experiments per year.

A lot of it they say is stored on robotic magnetic tape storage systems,
something we discussed in this thread here :-
