21. Death Star-Like Laser Cannons
- Chances We’ll See It: Medium to High
Normal lasers are rarely used to destroy, rather for things like aiming and even surgeries. However, when people think of lasers, they think of the big laser cannon from Star Wars. Could a Death Star-like laser cannon ever exist? Technically, yes.

Lasers can be weaponized. Therefore, we could make an incredibly large one. However, the overall physics is difficult. Not only how one would get it into space but also how you’d keep it in place, how to aim it, etc. As far as laser cannons that are smaller go. Yes, those are possible and some versions already exist. But shhh… the military doesn’t want you to know that.
