Hi!
I actually worked on a Sci-fi comic it was a lot of fun!
-just how science-y do you like your sci-fi?
I've read that there's a scale to measure the hardness of a Sci-fi story.
Example: a character is shown a machine for traveling into the past and asks, "How does it work?"
In soft SF: "You sit in this seat, set the date you want, and pull that lever."
In medium SF: "You sit in this seat, set the date you want, and drive to 88 mph."
In hard SF: "A good question with an interesting answer. Please have a seat while I bring you up to speed on the latest ideas in quantum theory, after which I will spend a chapter detailing an elaborate, yet plausible-sounding connection between quantum states, the unified field theory, and the means by which the brain stores memory, all tied into theories from both Albert Einstein and Stephen Hawking."
In really hard SF: "It doesn't. Time travel to the past is impossible."
I personally love Hard SF I love reading and eating up all the science behind the technology in the story.
Though this usually works for movies and video games but for comics it might lead to too much exposition.
So I went with medium SF it allowed me to explain the technology just enough where it didn't overwhelm the reader. It also allowed me to get away without explaining the science behind certain moments without having the readers suspend their disbelief.
Do most people even care if the science is solid?
It really depends on the reader. I think science fiction is a really niche and passionate genre. So generally i think readers really want the science to be on point! Otherwise it's just fantasy right?
**How much can I reasonably expect my readers to suspend their disbelief
-If the science is solid and well researched how much of it should I explain??**
This one is pretty tough again it just depends on the reader. For example Star wars, Mass Effect and Destiny are all Sci-fi with "fantasy" elements and have moments that the reader really needs to suspend their disbelief for a moment. All of them achieve this to a varied level of success but, they all make it out in one piece.
Oh! Science and technology change so rapidly! I'm worried that the science I use in my story will get debunked or disproved and THEN where would I be?
Personally i think you shouldn't worry! There's plenty of Sci-fi stories where spaceships travel through black holes and have other ridiculously outdated premises. Yet they are still a blast to watch/read! Also the story taking place 150 years from now also gives you the opportunity to bend some of the laws of science. It is after all Science fiction!
I hope this was of some help!
