Light do not go on into infinity, the Luminous intensity is proportional to the inverse of the square of the distance I ~ 1/r^2

A bullet of matter on the other hand does go on "forever"

least as I am aware of :-)

i dont think that applies to lasers when they are actually just a straight line of light and the light isnt moving outwards from that line.

It is a formulae set for spheres, but if you derive every point of that sphere you essentially get a light beam.

it all comes down to how powerful your Lazar is I guess, threes lot of stars we cannot see on the sky. (even from space)

Would gravity not have a greater effect on a projectile than a laser? Meaning its trajectory would be effected more and thus be less accurate (when dealing with extreme distance)?

well since we fly in pretty big and powerful spaceships of which some actually are said to be so big that their gravitation affects planets if they get to close, i guess we can assume that we developed pretty good lasers which don't behave like a sphere (btw the ones we do have now in RL dont behave like a sphere either ;) ). granted if they arent perfect their intensity would be reduced as is the case with the ones we do have in RL but having so advanced ships it could be possible that our lasers are that advanced too and they actually go on forever ;-) i cant possibly imagine why they would end after 200km because that would be a pretty ****** laser for how advanced everything else is ^^

Do not quote me on it though, i shall honestly say i just know for spheres, i would think the shape does not matter. ultimatly the beam would decay into infra-red like the background radiation.

so scenario 1 where threes no objects around, the bullet would have its effect longer. (it takes way less pain from the expanding universe, though were not sure if the EvE universe is expanding, it is to china so i guess it is?)

while if you got some kind of gravity, well, as said the bullet would miss.

The laser can be affected by gravity pulls, or electromagnetic fields, (though for an field to appear one would need a dynamo, aka something to that gravity so essential the same thing)

At the end of the day we're playing a game set in space as immortal demi-gods. If the game was 100% realistic it would just be boring old real life here on earth :p

well, if the ship you shoot at got lot of gravity, the bullet would just hit harder, not that it has anything to do with anything :p

but really? i know the titan is big, but that got to be some very very dense material in those things to put up such a reputation.

Well, as far as I know there's not even a theoretical way to create a totally non-diffractive laser because it would require infinite energy, so lasers actually won't go forever.

yeah i know thats pretty strange but its in the lore: http://wiki.eveonline.com/en/wiki/The_Titans_%28Chronicle%29


we don't know (a theoretical way) how to travel faster than light without blowing up the other end when we arrive but we still do. so just because we dont know how to create a laser that goes forever doesnt mean there is no way ;D. anyways somewhere the fiction just has to start. ofc neither light nor a bullet goes forever but a laser can focus the light definately farther than a sphere and who knows maybe the races of eve figured out a way to really make it go forever ;D

Regarding the bullet, I would tentatively agree, however we do not know yet if the universe would contract or not.

Regarding the inverse square, it presumes wave nature of light, without a mass. However, we know that gravity distorts the "trajectory" of light, therefore they may be scenario, depending on actual layout of the universe, where a beam of light could be going in circle, back to its point of origin ;)
