Can anyone tell me how an object can emit light/radiation when it has no energy source?
All objects have an internal energy based on their temperature. As they emit light, they cool down.I can't really give an example, but I was reading an article that explained the theory that an object moving at great speed emits radiation/light at the same speed as a stationery object. My thought was that if the stationary object has no energy source, how can emit anything?
