12 Physics Facts That Sound Fake (But Are 100% Real)

Your head is ageing faster than your feet. Lightning is five times hotter than the Sun's surface. And bananas are radioactive. 12 physics facts that sound made up, every one of them real and sourced, ending with the India files: C.V. Raman, S.N. Bose and J.C. Bose. #PhysicsFacts #Physics #Science Chapters 0:00 12 physics facts that sound fake 0:17 1. Your head ages faster than your feet 0:39 2. GPS only works because of Einstein 1:04 3.
