I do , the Space 1999 episode war games when the base was attacked by mk9 hawk...
From what I've read lasers don't work in space they seperate for some reason , I can't tell you science about why though it was a long time ago when Ronald Ragan wash president of the U.S. , he wanted to build satelites with lasers to shoot down enemy missiles , they nicknamed it the Star Wars...
Yes I believe in life on other planets but I don't believe we have been visited by any extra terrestrial beings for the simple fact of , if a race could actually have the knowledge of physics, technology, and understanding of the universe to build an engine capable of reaching other star systems...
One of my favourite movies so I would like to see a before or after but the prequel does have a sertain charm to it .
I always wondered why or how the skin jobs defied their programming
Tbh it's the first thing I can remember being really untested in , I don't know exactly how or what caused it just happened , SF is the most diverse genre it covers every type of entertainment and also broadens our minds to infinite possibilities and that is why I like SF :)
