The Source of Radio Waves

What makes things and men radio waves? Bell: We have a few sort of categories of things that can make radio waves. Everything in the universe gives off radiation, depending on your temperature. One source is just like magnetic fields, when they move toar magnetic field, they get bent. And we don't want to go in detail into the physics of lazers, but there are sometimes out there in space these dense pockets of molecular clouds. If life passes through them at the right frequency, it can become a mazer - basically a lazer, but in the micro wave spectrum.
