What exactly is the difference between science and science fiction? In class, we discussed the idea of speculative fiction - that science fiction is really an amalgamation of various aspects of human knowledge (culture, history, technology, etc.).
Per some vacation reading, I stumbled upon an allusion to science fiction in Adam Rutherford's "The Origin of Life'' and " The Future of Life". The book itself is incredibly interesting - the two parts begin on opposite ends and arrive at the
same conclusion in the middle of the book. It's a scientific exploration of just evolutionary biology, but reads super easily (5 star review, highly recommend to everyone). Anyhow, the excerpt that caught my attention was as follows:
"There is a branch of speculation that proposes the rather futuristically named 'Shadow Biosphere'. This is the idea that there is a second (or more) undetected tree of life on Earth, with hallmarks different from the ones on the only tree of life on Earth, with hallmarks different from the ones on the only tree of life we know of. But as it is, every life form so far examined is based on cells, DNA and Darwin. Discovery of a second tree of life here on Earth would give much-needed credence to the search for life on the other planets, as it would double the number the number of known successful origin of life events. It would show that we are not a fluke. However, science is based on observable evidence. Therefore the Shadow Biosphere, whilst sounding quite thrilling, is resolutely science fiction."
What intrigued me most was that Rutherford seemed to be blurring the lines between reality and the fictional or speculative aspect of science fiction - according to him, the existence of the Shadow Biosphere is hardly inconceivable, only hidden from us by the boundaries of our own observational abilities. In fact, all of "The Future of Life", an entire half of the book, speculates the future of biological evolution and corresponding scientific developments - the topics of bioengineering and genetic modification are eerily reminiscent of what we may have considered science fiction. In fact, upon further reflection, in Star Trek, a now considered old canon of sci-fi, weren't portable communication devices relying on radio transmission once considered science fiction? Hello cellphones.
There is almost something beautifully universal about knowledge - is it inconceivable that in the same way all organisms share the same basic genetic code, there is some central dogma that guides the collective human conscious? Our understanding of the world is limited by our powers of observation - there are certain natural phenomena that we cannot explain except by saying something along the lines of "that's just the way it is". Theoretical physics is all about exploring the underlying mechanics of our universe that humans, due to our physical limitations, cannot understand. For example - our sight is limited to three dimensions, but we've been able to visualize a four-dimensional cube (Easter egg - such a cube is called a TESSERACT, the same name given to the all powerful cube in the marvel universe, which contains both immeasurable power and the ability to warp the space-time continuum; argue all you want for Marvel and DC universes not being science fiction, they definitely incorporate strong elements of it). Super tangential, I know.
The point that I'm trying to get at is that often, we distinguish science fiction from reality, when in fact, as Rutherford hints at, science fiction or speculative fiction or however you'd like to think of it is often an exploration of knowledge at the boundaries of human understanding.
