Take the first message from @JoshFromSchool, who claimed nobody watches science movies for the science.

Dr. Tyson: your response?

I wouldnt saynobodywatches the science-fiction movies for the science.

I would say for sure @JoshFromSchool doesnt watch the science-fiction movies for the science.

So among all those who are inventing tomorrow, I do not expect to see @JoshFromSchool among them.
