No thruth

Yesterday I learned that there is no thruth. Everything you know is told to you by someone or something. Quite scary and beautiful at the same time.
No theory is correct, they're just ideas.
The only theory that might be correct is the evolution theory of Darwin. They say, of course, no one knowes. :)
So, our goal is to write a theory on a subject of your internship class. Something they say cannot be done, and still we have to do it. Haha. Mostly we have to show hoe smart we are. Mine will be about music and I am searching for articles and sources right now.
Back to work.
