Could grow lights on a massive scale replace 100% of sunlight for 100% of the growing season? In a world where pollution and population have drastically reduced the effectiveness of sunlight to grow food, would light-panels be capable of completely replacing the sun? The problem I'm trying to solve is rationalizing indoor farming for 100% of the Earth's agriculture. Piping in water is a bi... (more) |

Is it on-topic to ask about heavily modified science, or must the question always require an answer with a foundation somewhere in physics-as-we-know-it-today? For example, if someone wanted to ask about the physics of a universe where the value of C was dependent on the wavelength of light? (more) |
