Maybe if you harvested 100 grams of anti-matter. Lol but that will take lets see, 1 gram = 100 billion years (with current technology) x 100 = 10 trillion years.....

your calculation is off by about 6 orders of magnitude, but yeah, still a long time.

Hmm explain, because from what I have read it takes 100 billion years to harvest one gram. Unless it was 10 billion. They can only harvest a few atoms a year. A gram contains (what I believe) billions upon billions of atoms. If I am wrong please inform me.

Well we are really splitting hairs here, it takes a LONG time with either set of numbers, but ok:
According to CERN's website, the annual production of antimatter is about 10^(-8) grams, not 10^(-11) grams (so that's 3 orders, not 6). Your probably thinking 100 billion years to make a kilogram.

is that what we can make it at? our forms in the universe? because if it can form in the universe, we could mine it! Or others with better tech could..better word for mine "extract " maybe.

I know what you mean, and it's a great idea! But it is doubtful that a "vein of antimatter" exists. The boundary between a "vein of antimatter" and matter would be very easy to spot, even if the "vein" was in another galaxy. It would create a rather unique signature...

Vein ? lol well I was thinking of predictability and capture of where it could form. but if there would be a vein of this stuff, not sure if possible. and i dont think we should be making it yet in large amounts if any. we not really creating it but pulling it from some place. right?

Typically it is created "out of nothing". You just fire 2 electrons at each other at high velocity, the total energy of the system is now really high but the total momentum is 0. If you fire them fast enough, there will be enough energy to produce a large number of fermions (think protons and electrons) and bosons (think photons), essentially 50% of the fermions will be antimatter. Of course it really isn't out of nothing, as you expended a huge amount of energy in this process. So you don't net any energy from this process. If however you could find a huge pile of antimatter just sitting somewhere, well then you could net a huge amount of energy by just using that (of course these piles probably don't exist or we'd be able to see them, the reactions on the boundary between the pile of antimatter and the rest of the universe would be intense to say the least).

It's not really much different than how fossil fuels work. If you were to try to manufacture your own coal out of hydrogen and carbon atoms, you could do it, but you would lose energy in the process (but you would have coal). However if you can just find a pile of coal somewhere (coal mine), then you can net energy by just picking up the coal and using it.

Where else in the universe allows for photon particles to be slammed into each other like this? there is a reason God cast the anti out of heaven maybe..we connecting the sparks and sending a beacon of energy . little dot that blinks in same spot, someone will notice. if you can detect anti matter some how in the universe or photons being slammed into each other if usually don't happen. I don't think anti matter us created...I think that explosion of photons can occur in a electrical universe, and that blast is opening a door. pulling stuff in. for a split sec

Photon's don't interact directly with each other. You create antimatter by slamming fermions together. It works anywhere.

Well I assure you it is regularly created by humans by the process I described earlier (or similar processes). This process also happens in nature as well (but if you want a bunch of it, it's better to do it yourself).

In fact, in some experiments, antimatter is produced in the method above, then it is accelerated and collided in a head on collision with accelerated normal matter, to concentrate even more energy into a small location (you have the energy associated with their velocities + the energy of the matter/antimatter reaction) so you can create even heavier particles.
