About things they know nothing about?
I've been arguing with this one guy about time dilation in physics. He claims time does not dilate and it's just an effect on the instruments of measurement.
I wrote out the Schrödinger equation and he couldn't even make heads or tails of it. To wit: he has no idea what he's talking about. But he keeps running his mouth.
Would just walk away but he's in for the holidays with my extended family. I'm going to end up ripping his head off before the week is over, I can feel it coming.
