Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

If antimatter has anti charge and can disapear into energy that means it should have negative gravitational influence. It repells other atoms. That first of all means that you can not see "natural" antimatter anywhere where there is normal matter with normal gravity. It is the opposite of a magnet where different poles attrackt eachother. 

That also makes it possible to create gravitational strech if you have matter and antimatter near eachother. Similar to how the distance between particles in a wave change distance between them. That would mean your could travel faster than light while not traveling faster than light. You would technically time travel forward. Quantum mechanicly I am too confued to decribe how the two different probuability functions would work together. I don't even know how the function would look like.

Since you lose mass in every energetic reaction, you should be creating antimatter that makes pure energy with matter. That also means every endotherm reaction would seperate matter from antimatter? 

Is the big bang a thing where a lot of energy was seperated to matter and antimatter and once everything expanded it should go back to one big chunk of mass like a rubber band. That means that our universe is oscillating from mass to energy and back?

I am very confued, but that whole thing is cool.
