There have been many theories about the Universe, but they generally all share one fundamental postulate, the cosmological principle, which has two parts. First, the Universe must be isotropic (the same in every direction).

Being the biggest polluters, this resources create a lot of problems like the bad air quality, acid rains, and the climate change. Also, this resources are limited, so once the reserves of them are spent there will be no more of them, thus the humanity will be in big trouble if a proper solution is not found until then.
