Ah yes, "lasers"

Fun lil ole calc for you all to play with check it out.

I tried it with a 1 meter diameter iron traveling at mach 5 hitting the moon at 90 deg. resulting energy was 12 ton of TNT.

OK, so some of the Collectors use particle beams, I can understand that.  But why is the dominant weapon in every space battle we see giant laz0rs?  Aren't all of the weapons in the galaxy (except the geth) supposed to be based around mass effect technology?

 - In ME1 we see Sovereign, a reaper and whose technology is the base for every other technology in the galaxy, use giant lasers... for whatever reason.
 - In ME2 we see the Collectors use a giant laser as the main weapon for their giant poo ship
 - In ME2 now the Normandy, a non-Reaper/Collector ship, is using them too!  What they heck?

They are shooting down missiles for 10 years with experimental anti-missile laser weapons.  That is a technology we have today.  Why wouldn't they have lasers 173 years from now?

I never thought the Thanix cannon was a laser. You don't see beams move, they suddenly appear. The Collector ship had something like a plasma cannon I guess, and Sovereign's weapon did indeed look like some kind of directed energy. But that was it.

The Collector particle beam was focused radiation, I believe. Sovereign's weapons and the Thanix cannon were both beams of molten metal.

collector beam accelerates antiparticles to near light speed to inflict damage. when an antiparticle and particle meet, they aniliate each other (they explode and turn into energy)

Read that. Lasers are reality. The only thing holding back mass production of that is cost and size. In 173 years, they probably will figure a way to reduce the size and cost. Eventually, this will obsolete all missiles. When that happens, it is likely that a new arms race will begin for the most powerful lasers.

Ah, ok then. Looks like I'm rusty on my acronyms. If that's the case, then after looking at "that's impossible", I would have to completely disagree with the statement that DEWs are science fiction. Especially after seeing multiple demonstrations.

OK, last time: DEWs as typically depicted.  That is generally not a whole lot like anything in development, or that actually does exist, here in reality.  And yeah, we might be closer to personal systems, but they're still gonna impractical for anyone except well-funded militaries for the forseeable future, nor all that convenient for an individual (barring breakthroughs in power storage and the like of course).

I know we can't see lasers that are outside the visible spectrum. What I mean is that I can't see any reason for us to be able to see a laser beam unless it were shone directly at our face, because how would the photons reach our eyes?

Scattering.  Some atmospheres and especially dusty regions in space could make them visible.  Also, a nasty enough battle could spew enough particulate debris that they'd show up.

This. Also the complete episode of That's Impossible talking about energy weapons (as I said before, I don't know how to embed links):

All this talk about practical use of energy based weapons, we have already a ton of different theories how to build one, stuff that might even practically work. Laser, coil/gauss-gun, railgun etc... theories behind them are not hard. But AFAIK all of them have one problem, powersource. They all require ****loads of energy to work with same efficiency as normal gunpowder weapons. Hand held laser rifles are definetly out of question unless we invent some nuclear batteries, but do we have technology to build such weapons to, for example, tank mounted any time soon? If not, then they will all stay as theories that work on experiments, but do not really see practical use.

Though I could see such weapons mounted on ground, powered by powerplant near them, IE anti-aircraft weapons. But are they cost-efficient enough to replace standard missiles?

oooor you could have read the codex rather than asking assinine questions

do you mean like this?

You think they're using lasers? 

Sovereign used a mass accelerator that fires a stream of molten metal. It was not a laser. Collectors use some kind of particle beam, which is not a laser. It's a stream of particles, as opposed to a coherent beam of photons (laser). The Normandy uses a miniaturized version of Sovereign's main gun, known as the Thanix cannon.

You would know all of this if you read the Codex.

We have in our U.S. arsenal now 2 Boeing 747's with LASER defense weapons mounted in the nose.  WE have had this tech for over 10 years now it is a reality.

The U.S. Navy has several working proto type rail / coil mass drivers now. Able to throw 5 kg slugs of ferris metal at speeds in excess of mach 5, ranges exceeding 200 kilometers.

The Navy is planning on using these coil / rail weapons as upgrades on our aircraft carriers, and other ships that are being built today. Theses weapons are not fiction but reality. We have them now. The technology is solid and practical. Ofcourse I do conceed that they will be used on ships that have nuclear power plants on them, though we have been using nuke powered ships for what 65 years?

Also I would throw out that the sci-fi industries, books, television, comics, games, and other media have had a major influence on scientific research and reality. Throughout our short existance, first it takes a dreamer then someone to build it...

I want to use plasma based weapons.

Why are all bullets in ME so tiny? Why not launch tungsten telephone poles in their magnetic acceleration cannons? Now that would be awsome!

[Muffildy]

Lasers in space wouldnt be visible unless they are of the visible light spectrum and are being projected through some sort of atmosphere; so at the start of a battle nothing should be able to be seen, but after a few ships have been blown up the leaked gasses and dust/debris might allow you to see them.



As far as weapons for use, i am suprised that the reapers arent using a nano-tech cloud type dispersal. there are a lot of sci fi books and movies that use this idea - a cloud of nano machines that disassemble whatever they come into contact with and make more of themselves out of it.

1. The biggest problem with plasma weapons is that they wouldn't work. Like, at all.
2.  It's better to have lighter things going at higher speeds than heavier ones going at lower speeds, because maximum combat range is determined by the velocity of the projectile.
