Herk - what are the What if's-the possibilities science fiction suggests?
The possibilities are unlimited. In the Golden Age of science fiction, science was in a comparative infancy to today. There was a lot that was possible. As a genre, science fiction has rules: it's really about the present. If it wasn't about the present, it would not be germane to our lives and no one would read it. But the endless possibilities of ships that can travel through time or space with few limits or a mind that can be expanded without limit or whatever . . . it's boggling.
The spaceships and interplanetary travel and fantastic machines are not the story, they are the vehicle by which the story is told. Science fiction explores concepts. Characters are often secondary.
Enter hard science fiction.
As science became more available to the mainstream, a lot of things that used to be used in science fiction became improbable or impossible. Science fiction became divided more into hard science fiction and fantasy. In fantasy, anything is possible, but not necessarily believable. In hard science fiction, you can't just make anything up. It has to agree with what is currently known about science. There is a wriggle factor in that if something has not been proven impossible, it can be used. So, for example, a spaceship can go faster than light if it "cheats" by skipping over layers of folded space or by some other little-known method. (Particles can disappear at one place in the universe and reappear at another with no appreciable time elapsed, or so I'm told.) Until someone proves that this cannot possibly ever ever ever be done, it can still be used. Nothing, says Einstein, can go faster than light.
So, things that are still speculative can be used. A few years ago, I read a story about a slightly futuristic society where the protagonist had access to advanced research submarines and was able to examine life growing around the volcanic vents deep in the ocean. Is there no wow in that? All was within the realm science as we know it, with perhaps just a skosh of wild speculation thrown in.
What if you could enhance the human body? Give it better vision, faster reflexes, a pouch to hide things in. How about immortality? An occasional visit to a facility that can, so to speak, wash your genes and make them like new. Is that a wow or what? Dr. Ben Bova wrote a non-fiction book (he also writes fiction) called "Immortality" in which he opines that there may be people living today who will virtually never die.
There was a story by Isaac Asimov, as I recall, where an alien race interacted with humans and (spoiler alert!) when the subject of life after death came up, the answer the aliens gave was something like: "We live on. You do not." Wow.
Percival Lowell believed that the canals on Mars could have been built by intelligent life. Giovanni Shiaparelli was the first to observe them through a crude telescope around 1877. In 1912, Edgar Rice Burroughs wrote a story called
A Princess of Mars and those canals played a big part in that story and the sequels.
". . . The transition had been so sudden and so unexpected that it left me for a moment forgetful of aught else than my strange metamorphosis. My first thought was, is this then death! Have I indeed passed over forever into that other life! But I could not well believe this, as I could feel my heart pounding against my ribs from the exertion of my efforts to release myself from the anaesthesis which had held me. My breath was coming in quick, short gasps, cold sweat stood out from every pore of my body, and the ancient experiment of pinching revealed the fact that I was anything other than a wraith.
". . . As I stood thus meditating, I turned my gaze from the landscape to the heavens where the myriad stars formed a gorgeous and fitting canopy for the wonders of the earthly scene. My attention was quickly riveted by a large red star close to the distant horizon. As I gazed upon it I felt a spell of overpowering fascination--it was Mars, the god of war, and for me, the fighting man, it had always held the power of irresistible enchantment. As I gazed at it on that far-gone night it seemed to call across the unthinkable void, to lure me to it, to draw me as the lodestone attracts a particle of iron.
My longing was beyond the power of opposition; I closed my eyes, stretched out my arms toward the god of my vocation and felt myself drawn with the suddenness of thought through the trackless immensity of space. There was an instant of extreme cold and utter darkness.
" . . .I opened my eyes upon a strange and weird landscape. I knew that I was on Mars; not once did I question either my sanity or my wakefulness. I was not asleep, no need for pinching here; my inner consciousness told me as plainly that I was upon Mars as your conscious mind tells you that you are upon Earth. You do not question the fact; neither did I. "
Of course, we now know that there are no canals on Mars, unless some putative Martian has covered them over and hidden them from our sight. The Martians in the story call their planet Barsoom. Do you know, I'd far rather travel to the fabled Barsoom when I die than some place with worthless gold streets and gates encrusted with mother-of-pearl. Wow.
