So, here's a fun one

 I just found out about this guy.

Ettore Majorana was working on neutrino masses when he decided to take a sea voyage in 1938, from Palermo to Naples.

He vanished.

Without a trace.

The logical explanation, of course, is that he went overboard while nobody was looking (Over 165 people have vanished from cruise ships since 1995, and that's presumably what happened to them too).

But I can't help but wonder if he was disappeared by the Illuminati, aliens, etc.

There's a story in there somewhere...
