Is the theory of the hollow Earth, or the halo planets even possible??
(I don't find it logical in anyway, but I wouldn't say no for a possible isolated underground environement, propably a full rich eco system somewhere (not necesserly harsh conditions, besides the absence of sun light (except some kind of glowing lifeforms like jelly fish) )undiscovered, besides we all know that life can exist almost everywhere, harsh conditions are no longer a reason to say that life can't exist in places where it's harsh)
