This one actually doesn't go against any established scientific theories, but rather challenges our common sense assumptions and reaches a conclusion too bizarre to be taken seriously by the scientific mainstream.
In this article, I am trying to show (ideally, prove) that any technology which allows any civilization to leave a noticeable signature on a stellar scale inherently causes the destruction of said civilization. If true, it means we can solve the Fermi paradox without the invocation of the anthropic principle or any assumptions about alien technologies or lifeforms other than pure definitions.
All counterarguments expressed so far are collected in the "Discussion" section. I am looking forward to adding more.
