What is the difference between the sf sub-genres of steampunk and cyberpunk?
– Both steampunk and cyberpunk have to do with the advancement of technological innovations, but the difference between them is the time period. Steampunk involves a more 19th century wild wild west time period with the combination of fictional technology and the innovative technology of that time. An example would be the movie Atlantis: The Lost Empire. While cyberpunk involves a more modern time period with the combination of technological advancements in this time period and the addition of more fictional innovations. An example would be Blade Runner.
6/ Hard SF is based on science, but not necessarily scientific fact. Works of hard SF make use of the scientific method, where it is not only important to know that something is possible, but also to know how it is possible and why it was made possible. Things that are not based on currently proven scientific facts have to be justified with their own scientific logic. It may be more appropriate to think of it as “fictional science.” (Robert)
