I had a professor of physics who was obsessed with String Theory. He dedicated the week before finals to educating us about it. I walked away from that week completely unprepared for final exams and thinking to myself that there is no logical reasoning to back up ST whatsoever and that all of it was nutty supposition and pseudo-science. Sure it might be fun to consider and wonder about, but it doesn't make a ton of sense (if any) and exists as a religion for physicists who in my opinion feel a need to believe in God, but are uncomfortable accepting that one exists, so they fall into this weird extremely high level pseudo-scientific "cult" of String Theory.
Celestrians point seemed to be, that if someone said to you that:
"
String Theory G-d is nutty cult crap for
physicists believers. I don't buy it."
That it wouldn't be constitute a very good argument.
And that non believers in this thread generally haven't just said "religion is stupid/for stupid people", but have actually tried to engage the religious beliefs with a bit of depth and understanding.
And that it would be nice if it worked both ways.
Saying that,
You're right that its not proven, but it doesn't mean that it can't be, and that there isn't interesting work being done in String theory.
Although I'm not sure Celestrian was making a point beyond this.
There was theory for black holes long before any physical evidence.
