Why are lasers always made visible in movies?

Right. My area must not be very dusty, because I can't see the light emitted by the headlights of my car unless I'm looking at the source or the target.

same reason you hear sound in space, computers all have nifty sounds that tell you how hard they're working, and password-cracking tools know exactly how many digits of a password have been guessed right so far.

It's entertainment not science.

Right. But it gives the wrong ideas to people actually facing dangerous lasers. 😛

People who actually work around high power lasers are trained to know the hazards. We do not rely on the movies for such information.

The equipment set I support includes high power (10W) UV lasers. So I sort of know what I am talking about.
 
wouldn't be very exciting to just see people collapse randomly. or stuff blowing up randomly. or shields on starships lighting up inexplicably. i mean, where's the excitement in seeing stuff blow up without that cool red/green/blue/{pick another random color} beam? :evil:

Someone forgot his sense of humor... 😉
 
> like in star wars. arrgh they move slower than bullets.

At the risk of sounding like a gigantic nerd, they don't use lasers in StarWars. They use blasters... i.e. charged-particle beams. Obviously, they won't be moving at the speed of light (granted, they should move faster than bullets).

My favorite bit is when ppl use the computer and whatever's on the screen is projected onto their faces. Somehow, monitors also function as projectors.

And I think that all passwords get cracked in exactly three tries.

i love the random typing motions and generic desktops that always launch right to the program needed (also: everything in movies/tv is downloaded to stuff "let me download it to this floppy and we'll get out of here.")

"Let me copy/paste it to this floppy" sounds really lame.
