Science fiction is cool, but sometimes it scares me that some day it could be real!
You're right, a lot of science fiction is grounded in real science
I like to read science fiction books - some authors are quite imaginative!
You're right, sci-fi contains many different genres and themes
I used to watch The Twilight Zone - that show was awesome!
I did too! Some of the episodes were sci-fi while others were more fantasy
The sci-fi ones were the best!  It sure made one think about what could possibly happen!  
So true, sci-fi really makes you think about the consequences of science and innovation
