Kentucker, it scares me to death that our brightest minds in the field are dedicating their time and brilliance on a field that is bunk.

Bunk? My good man!

Lots of young minds are afraid to speak out on it and think it to be career suicide to not take part it.

Where are you getting that idea? It's the most exciting subject in physics. Brilliant young minds are orienting to it like moths to a bright light in Summer.

I see no way to ever test string theory.

There's no way to test it right now. We haven't detected dark matter either but that hasn't stopped scientists from finding its effects. Hopefully the same will happen for strings. The more we discover about the quantum world, the more likely we are to see the effects of strings. That's just a logical progression.

It is beautiful on the math blackboard but new theories always replace older, inadequate theories such as relativity replacing newtonian physics. String theory has not done that.

Sure, that's the way science works. Newton was the authority until Einstein came along with general relativity. General relativity didn't have all the answers either, however. It is completely lacking regarding quantum mechanics.

String Theory does explain quantum mechanics and general relativity. Want a Theory of Everything? Well, it has to include strings.
