The extreme summary as I understand it is that these two men, Igor and Grichka, are science fiction TV producers in France who managed against all odds to gain PhDs and spent a while basically trolling scientific journals with ridiculous, incomprehensible theories (including a major one about how they apparently could figure out what happened in a certain point during the Big Bang), and go on forums using pseudonyms or their friends to support their work and insult critics. They spent a lot of money with plastic surgery to forget up their faces, and Igor has like 6 kids.
The more I read, the more I realise that summary is extremely limited, but it should help some people here get the basic context.
