Anti-Matter Feels Anti-Nurtial Mass or Anti-Gravity

This is a very contrarian episode. We are talking about whether or not anti-matter feels anti-gravity. It turned out to be a pretty complicated question because it first of all you have to think about whether anti-matter has anti-nurtial mass or anti-gravitational mass and whether or not if they're the same thing according to i-sign or maybe they're not. This is definitely something we should check we should go and see whether anti- matter can feel anti-gravity just because general relativity is so successful. On the other hand why do we do experiments we don't do experiments just to like yawn and check the boxes off of theoretical predictions we do
