Proof that 'common sense' is a myth. 1. You have never touched anything, you've just been repelled by it. If you were to somehow overcome the repulsion you'd actually go through the object like a ghost. 2. There's no such thing as a straight line. 3. Space cannot be mapped on paper. 4. There's not a single atom in your body that was there when you were a baby. 5. Many of the stars you see at night went supernova millions of years ago. Science is awesome, amirite?
