matter to anti-matter conversion

[paragaster]

Is it possible that matter would be converted to anti-matter in the future? Is anti-matter creation possible in a black hole?

We know that the amount of anti-matter created at the beginning of the Universe was small. As the Universe expands we have space-time equations changing. Have such experiments been tried in Laboratory?

Anti-matter is created in pair production,

or decay of unstable particles, unstable isotopes.

Anti-matter is created even by your body.

 

Carbon-14 decays to anti-matter anti-neutrino.

So the same Potassium-40.

 

If your weight is 80 kg, approximately 2900 decays of C-14,

and approximately 10000 decays of P-40 happens per second, in your body.

Therefor you're making over 1 billions new anti-matter particles daily.

Then again, neutrino's and antineutrino's might be the same thing.

There are some particles which convert or create more matter than antimatter (know as CP violations, because they violate the parity and charge symmetries). Some particles oscillate back and forth between matter and antimatter

There was also a hint that these were asymmetric, but that was in the direction of converting antimatter to matter. There's also the Baryon asymmetry problem, which again suggests antimatter converting to matter.
