When people try to convince me my cellphone is giving me cancer, I ask them to prove to me that using a cellphone for fifteen minutes is worse than going outside in the sun for fifteen minutes (sunlight is objectively more likely to give you cancer). Cellphones communicate via microwaves, which is just electromagnetic radiation (EMR) of a lower-energy (per photon) wavelength than visible light. Yes, the UV component of sunlight can give you cancer because it's just barely high enough energy to be ionizing. Visible light won't do that, and microwaves are safer still. Oh, thermal burns can cause cancer too you say, and we use microwave ovens to cook things! Yes. My phone has never cooked me though. A 3.7V, 3700mAh cell phone battery contains about 10 Wh of energy. A typical microwave oven uses around 1000W, so it would drain a cell-phone battery completely in around 36 seconds. Try putting a kilogram of something that's mostly water in a microwave oven for just 36 seconds. It's barely going to warm up. I wouldn't be worried about my cellphone cooking me even if it lasted just 36 seconds on a charge, but mine lasts for many hours. Can I prove that your phone isn't giving you cancer? No. That's not how science works. I can't prove the theories of gravity or relativity either. When I admit this, some people pounce on that as if this lack of proof is something that must be acted upon. Well, I can't prove a meteor won't crash through your roof and kill you tonight, or that a mega-eruption won't end civilization tomorrow, or that a parasite from some half-cooked beef you ate last week won't spontaneously mutate into a chest-burster like in "Alien". What are you going to do about those smart guy?
