    Cause, you know... mirrors...
    Just mirrors.
    Hehehe

    Anyway, I have no idea how spaceship battles would happen, but distorting light is easy, at that point there will be some developed way to deflect electromag waves (like the earth does).

    Mirrors aren't 100% reflective. They use lasers to cut mirrors to shape, y'know.

    Also, mirrors are designed to reflect certain frequencies of light better than others. A laser doesn't need to be using visible light.

    And a speck of dust on the surface? A fingerprint? Anything? Once the laser hits that, shit gets even worse, and now you've got a gaping hole in your relatively pretty fragile mirror surface.

    I was just telling that lasers arent a superoverpowered weapon that you cannot avoid.
    Again, it's easy to distort light and at such a tech point there will obviously be a way to not let the beam hit your ship.
    And also, you don't have unlimited distance, because a laser isnt a perfect paralel beam, but a cone.
    So there are relativelly big losses under very high distances.

    The big loss is usually due to an atmosphere, which refracts the laser outwards into a cone. In the vacuum of space, there is no atmosphere to cause that spreading, and it's be negligible with the proper equipment (and future technology).

    Start at: Directionality and beam divergence.

    I know how lasers work. My point is, the effect would almost insignificant in a future day where we have more precise engineering and better tech, and it definitely a lot smaller than the diffusion the atmosphere causes. Certaintly, a laser could still reach a LOT further and have higher chance of causing damage than firing any bullet would.

    I'm always fascinated at how cultures and trends change over time. Simply look at people from 1913 and compare it to those living in the middle ages, and yet in most cases the future is always depicted as: "The 21th century, BUT WITH LASERS AND FLYING CARS".

    Well, sure we already have those but you get what I'm saying......

    Think about what you thought the future would be like in 1980. Now look at the calender.
    So disappointed.

    my biggest pet peeves are:
    open flames in the vacuum of space, sure an explosion makes a bit of sense if it contains fire, provided oxygen comes from explosive decompression but the wing of a fighter, in complete vacuum, usually without any actual combustible fuel is ridiculous.

    that and ship thruster have a complete disregard for newtons first law, in atmosphere you have air resistance to compensate for, in space there is no reason to constantly have your thrusters on, your not going to slow down in any reasonable amount of time.


    on the plus side the smart phone is far cooler than most other communication devices thought of in those times, there's not many cases of showing a small object containing mans collective intelligence being used to look at cats and argue with strangers for no reason...

    The reason why this happen is to appeal the audience, same as when George Lucas and other producers make sounds in space. Imagine the Death Star or a Star Destroyer silently imploding
