I see you have a grey beard. Were you born with that beard? No? Where did it come from then, if time doesn't exist?

You see this all the time. People spend a little time studying physics and realize that time is a much more complicated thing than they originally thought.

But because they have a very high opinion of themselves, no mathematical background and no patience to study, they just define time out of existence entirely.

"Stupid Newton! Idiot Einstein! I, Head, am so much smarter than any of them, because I know that time does not exist! I can't explain what this actually means in practice, or use this to predict anything or write down even one formula, but it makes no difference, because I am a great scholar, and whatever I say is true!"
