Antimatter falls down, not up: CERN experiment confirms theory

Not only does it exist, but bananas give off a fair bit of antimatter due to their decaying potassium isotopes.
Allegedly, im not smart enough to verify it
AFAIK, yes.
There are some very small differences between matter and anti-matter, but I don’t think any of them affect radioactivity.
