In real life everything works by the law of physics, but in a 3D engine, you have to calculate and rasterize everything, and programmers don't calculate all the shadows if you can't see some of them or if some are not needed for certain reasons (see bellow for more)

I understand it, that's why I wondered. In real life lack of lighting = darkness and lack of heat = cold.

And thank you for your detailed explanation
