Yeah I mean it's not impossible to have an arts degree in physics. Or two bachelors.
The only people I know with two bachelors got them at different colleges/universities. Or at the very least, usually many years apart.
Most people just have a minor if they are studying two main fields.
It's also sus he kept saying he has a graduate degree when he only has a 4 year degree. (In the U.S, at least, a graduate degree is a masters or PhD).
And even those two bachelors he has are questionable if he actually earned them. Or even one of them.
Even if he has a legitimate bachelors degree in physics. That level is just learning foundations. Not conducting research. Not developing anything new.
