Nice to meet you, Kuai. Or would you prefer Liang? I'm familiar with Earth, so you needn't worry.

About that-- While we are limited in means of sources of light, do you know if anyone has looked into amplifying them or light transference? There are clearly rules here about how sources exist, but light does appear to spread in a way that they must obey some physical law similar to what I'm familiar with.

That is to say, I'm not exactly a scientist, but mirrors and lenses have their functions beyond the obvious.
