Re: Possible Alien Life
The discovery of life deep in the oceans at tremendous pressure or bateria near hot mineral springs shows how adaptive life can be. Animals live high in the mountains, in the deserts, in the artic. These all show that a variety of environments can support life. It may come down to an optimum environ for fastest evolution. The earth seems to have served the purpose.
The need for liquid water is probably one of the basic criteria. More water moderates the surface temperature, while more pressure allows for more water. There is probably critical gravity that keeps the water from going to space even with high surface temp. if gravity gets too high life may remained in the water where one can feel weighless.
