I happen to know someone who is always at the forefront of conspiracy theories.
The newest trend seems to be that COVID -19 is caused by graphite oxide. That is some sort of nanoparticles. And of course it is mixed in with the 5G Bill Gates theories.
I don't know how they arrived at this BS, may have some English language source. In German I only found some news from last year about a Covid test that uses that material, but I don't think that is in use even.
