Because anti-matter is unstable and it get immediately "annihilate" into energy, just like you say...

Also, just because you can create anti-matter in your lab does not mean that it exists in a stable form in the Universe!

When you say "At any rate, by looking at the many anti protons stored at Fermilab, we can infer the average time they must live. We can state that our experiment would have seen at least one decay if the lifetime were less than 10,000,000 years". That is boggus at best since you are "sustaining" them artificially via EM fields that require a lot of energy in order to try to maintain this anti-matter artificially stable! You take those EM fields away and the anti-matter gets quickly annihilated into energy...

Either case, it seems like the particle physicists have a fertile imagination and are having a lot of fun while searching for this 'God particle'!

I am following the debate, so don't worry about that...
