I have heard of some rumors going around about a living organism based on non-carbon. Is Has research been done with real form of life based on non-carbon? Or carbon-based life is only type of life what humans know of?
In a word, no. There are some good chemical reasons to expect all life to be carbon-based. Of course, it is no longer a silly fantasy to imagine an artificial intelligence that might qualify as life. (Still FAAAARRRR in the future, though, if ever.)
