Extra-terrestrial life may already exist in the shadow biosphere.
What the hell is a shadow biosphere?
It is the vast possibility of life that is composed of elements that are so far unknown to conventional biochemistry. This includes organisms that may be based only on RNA and use alternate amino acids, organisms composed of dark energy/matter, organisms that inhabit unviewable regions of the electro-magnetic spectrum and potentially organisms that are too small or too large to observe (sub-nanobacteria, mineral intelligence, or extra-planetary consciousness).
Closer to consensus reality the shadow-biosphere includes extremeophiles, life that can live in terrestrial toxic environments (photos) like Mono Lake, CA or the cosmic radiation of the vacuum of space (mushroom spores!).
This has launched a “mission to Earth” in which scientists are looking for the origins of life on Earth by finding organisms that can live beyond the reaches of our world.
Not only could alternative forms of life be living on our planet unobserved – life may also exist in the multiverse – or at least some multiverses.
As far as oversimplified-combined-fringe-theory goes, I’d say the shadow-biosphere delightfully brings together extraterrestrial life, panspermia, ghosts, mineral and planetary intelligence, and space traveling mushroom consciousness transferal all into one neat little package.
Too much? Don’t think. Work on your prescience.
