Actually, it comes from the conversion of mass to energy. Ever heard of fission?Theoretically, if there is a shadow, there must be a sun. Without a sun, there can be no shadow.
Unless you have, you know, electricity and a lightbulb. Or fire. Or anything else that makes light.
The energy that generates the electricity to power the bulb inevitably comes from the sun...
