When scientific theories are proven multiple times by the reality-matter and antimatter, and are argued in line with natural and further cosmological universal laws, then it can be said that such theories are grounded on truth, and verified through large numbers of different experiments. Otherwise, our humanity will come around in circles, discovering and rediscovering the same things which our ancients have copied from the extraterrestrials visiting our Earth. Nobody likes a stagnation in knowledge, time and space, which affects negatively our standard of life on Earth.
