This thread is proposing the infinite-infinite universe where all conceivable possibilities exist within our infinite universe. This theory completely allows any contradiction within it's terms because that would be just another possibility (or combination) so a red planet exists and doesn't exist at the same time. Anyways the theory is COMPLETELY CONTRADICTORY and makes no attempt as to limit the contradictions. IF every conceivable idea, concept, matter, universe, planet etc. exists then there is no need for any explanations of anything since everything is just a given combination from the infinite amount of combinations. You need to explain something if there is only one possible path within a multitude, but in the infinite-infinite universe all the paths are simultaneously present including no paths and only a few (there goes the contradicton which is acceptable). This is somewhat an aesthetical view of the universe. The theory of the infinite-infinite universe is the theory where everything including all contradictions are present and acceptable. I also want to add that you must be careful as to what you are referring the infinite to. If you are referring to an infinite universe in space extension or time extension but within the physical laws of our universe as known so far, then all these weird possibilities (planet of elephants) are most likely not possible. But if you refer to an infinite universe in terms of "possibilities", "concepts", "laws of physics", "combinations" in other words an infinite universe in terms of all possible "concepts" conceivable, then you are no longer dealing with the realm of physics but metaphysics and philosophy and thus the infinite-infinite universe with all its acceptable contradictions.
