Thinking outside the box.

5 minutes in and the CERN physicist already makes an unproven assumption that he calls knowledge:

The galaxies rotate because of dark matter.

I highly recommend everybody who is interested in "thinking outside the box" to look at the electrical universe and plasma universe theories. There are explanations that don't need the invention of invisible matter to make things work.

So, this "scientist" thinks he knows something, while in reality, it's just a theory. This already tells us something about his mindset.
