When you google for "electromagnetic spectrum" images for a presentation you're doing for an astro class, among the top 20 hits is this.



I'd totally forgotten about it.

let's suppose that you _wanted_ to create a visual effect like that of the Death Star Laser in hard vacuum. How could it be done?

Plasma!

So a beam of plasma? Neato!

Yeah, as I said, ask an engineer. :)

More like a packet, really. You could electromagnetically accelerate it.

You'll notice that "lasers" in Star Wars have perceptible travel times, meaning they can't actually be lasers. Clearly, they are plasma slugs.
