how can you say that we have created antimatter when we cant prove it. yes we have theories, and those theories show that we may have made it, but they cant prove it. Theoretically, however, the antimatter that we may have produced, assuming that it exists and we are not just misrepresenting it, it very unstable and is very dangerous, but in these accelerators, it is contained where it can do no harm.and since we know so little about it, and have produced such a little amount, how can we say it doesnt produce gravity?

we can say that the universe is expanding at an accelerating rate, but that also is hard to tell because we have only been around for a few hundred years (at least in our observance of deep space) we have no proof for any of this. also, some parts of the universe may be expanding faster than others. who knows?? nobody. and our measurements are based on very trivial things like brightness of stars and such, hardly concrete.
