K it's actually not a computer question.. but
If you stand on one place on earth, is there a term for all the sky/space you can see from that single vantage point ?
Or, if you had a sphere, someone standing at one point with a laser that could be seen to an infinite distance would be able to shine it in a cone(ish) shaped area above them, what's this called?
Trying to help a friend writing a story, wants some kinda ground based weapon to be able to destroy anything it can see from ia fixed point on a planet, was wondering if there's a more intelligent/astronomical/scientific term to use than "line of sight from a fixed point on the planet"
Thanks as always if anyone has any idea what I'm talking about.
