In ME2, when you're doing the whole galactic exploration and strip mining thing, your ship will accelerate when you push forward and will slow down and stop when you don't, taking up fuel the entire time you're moving. All well and good except for one thing.

Space doesn't have friction.

why does the Normandy stop and why do we need fuel to continue moving forward after we hit top speed? we only need it to accelerate and deccelerate.

Did you, perchance, miss the opening premise of the game?

You know, the Mass Effect? Mass Relays? FTL? Biotics? Element Zero? Stealth in space?

Mass Effect cause cancel out physics. Just watch how the Normandy banks in space, as if its flying through an atmosphere.

The only thing in the ME universe that obeys the laws of physics is a 20kg ferrous slug.

And if you fire the thing... you are ruining someone's day! That is why you don't EYEBALL it! You are not a cowboy shooting from the hip!


lmao... I love that little exchange!

Not according to the Codex:

Any long-duration interstellar flight consists of two phases: acceleration and deceleration. Starships accelerate to the half-way point of their journey, then flip 180 degrees and apply thrust on the opposite vector, decelerating as they finish the trip. The engines are always operating, and peak speed is attained at the middle of the flight.

I'm starting to REALLY question the validity of that f***ing Codex. The whole point of using dark energy for FTL is that it bypasses the laws of physics, so why they would apply newtonian mechanics to FTL is beyond me.

You wish to question the Codex... written by bioware... as lore...

The idea of accelerating to the halfway point makes sense, when you take into consideration the solar winds, gravitational effects and numerous other things, which, when you consider how the drive core works - by changing the mass of the starship - will still have an effect because the mass will not be reduced to zero. (You cannot exert a force on nothing)

Whether that means they are creating a localised phenomenon in which the mass of nearby photons is also reduced, increasing their velocity so that relativity is changed - *shudder*.

I remember having these discussions in Physics lessons. General consensus was that ships in sci-fi either passed through an anomaly of sorts to enter another type of space where our physics doesn't work the same way (babylon 5 as a prime example), or created a "bubble" around the ship which changed the local laws of physics (seemingly what Warp Drive does on Star Trek, and my assumption for what Eezo does).

My reasoning for the latter is solely because you can see a ship that is in (Eezo induced) FTL - though you may not notice it.

And with that... *passes out from overuse of brain*

What about life support and other things. They might use fuel.

[Skirata129]

actually, I think the most realistic form of travel they could have used would have been exploiting wormholes or creating them by using the mass effect fields to bend space and time around themselves through manipulation of the ships gravitational field.

What I really wonder is how a ship can travel from a relay, like the Alpha relay to...say, the Citadel, and not run into anything hazardous, like a sun, an asteroid belt or a planet.

Which is not only impossible but also very improbable. Especially when at those speeds. Even small particles should hit the ship like bullets when it goes that fast.

The relays create a zero mass tunnel. If you have zero mass, you cannot interact with matter or energy. Just look at neutrinos.

I would assume it would have something to do with this:

masseffect.wikia.com/wiki/Mass_effect_field

In space, low-mass fields allow FTL travel and inexpensive surface-to-orbit transit. High-mass fields create artificial gravity and push space debris away from starships.

[Archereon]

The big problem with the physics of mass effect is that it pretty much just ignores all the consequences of negative mass, which would be necessary to achieve FTL travel within Relativistic Physics (and is generally assumed to be impossible to achieve).

These consequences include.

1. Time Travel (backwards)

2. All forces having the opposite effect that they would in a positive mass system (pushing on a negative mass makes it moves towards you.)

2b. All of the atoms in the negative mass system flying apart since the Strong Nuclear Force is working in reverse.

Of course, the game would be no fun if BioWare acknowledged all those nasty effects, so yeah.


Btw: Why does nobody ever bring up the game's supernatural elements? (Reaper Indoctrination, the apparent telepathic abilities of Asari, Asari in general, ect...)

It was problomatic in ME2 that the Normandy SR2 could fly through suns, or that it wasn't affected by gravity fields.

It would be difficult if The Normandy was true to life however, ships in space that burn fuel to accelerate must burn the same amount of fuel to decelerate, it would be a bit complicated in a fun console/ pc game.

This would be true for ships using conventional thrusters only. Because of how FTL mechanics works, it does not apply to the ships with FTL engines engaged.

Have to disagree on that Arcian. Normany uses 4 anti-matter thrusters.

Anti-matter thrusters are conventional thrusters. My point still stands.

S.A.K wrote...

So they will take same amout of fuel to decelerate.

Yeah, if the FT[/u]L engine is not engaged. While in FTL mode, the general laws of physics are thrown out of the window due to the use of negative mass and inertia, which bypasses the laws of physics entirely. In other words, Newtonian Laws [u]no longer apply.

Seriously, no offense, but how many f***ing times do I have to repeat myself for people to understand?

There is no special "FTL drive". anti-matter thrusters + Tantalus Drive Core IS the FTL drive. Read this and you'll get itB)

I'm going to play skeptical and say that I don't think they can push away suns. Or black holes.

That makes even less sense to me. Then the crew should phase through the ship or not be able to interact with anyone or anything during FTL.

Bah, I'm giving it the benefit of the doubt, since I'm more than likely overthinking it.

I think you're putting the cart before the horse, chief.

There's that whole thing about it being impossible to travel faster than the speed of light, also "element zero" doesn't exist.

I wouldn't worry too much about consuming fuel for intracluster travel.

Actually,if you beleive in the ancient astronaut theory (theory that man was cultrally uplifted 1000s of years ago) when they were building the pyramids there was stories of a white paste or paper and it made the blocks lighter with a handheld device.Not exactly "Eezo" but it is changing the mass of something.

What good would that do?  Neutrinos aren't massless.  Also, they do interact with stuff. How do you think neutrino detectors work?  Also, "zero mass == can't interact" is nonsense.  Photons really are massless and interact at the drop of a hat.  This is, for example, why you can see.  Or, you know, exist at all and not fall apart into a collection of bare nuclei and free electrons.

Hm, out of curiosity, just how much do ME fields violate conservation of energy?

Another point where physics doesn't work like it should is gravity on the Citadel. Somewhere on the Citadel hub section (middle floor), there's a warning which says that dropped objects will fall sideways due to the Citadel's gravity being centrifugally generated. However when things actually do drop (such the mechs from the overhead cables in Garrus' loyalty mission), they fall straight down.

It's actually centripedal acceleration. Centrifugal acceleration is the acceleration people think is happening when the frictional force between an object interacting with the object that is being affected by the force is too small to keep you moving with the object being affected by the centripedal force.

The easiest example is when you're in the car and you start moving to the left side of your car when you turn right and then your seatbelt/door "pushes" against you, well that's the normal force the door is exerting due to the centripedal force the car is undergoing in order to make the turn. Every part of that car that isn't securely fastened is undergoing that very same force, in fact even those that are securely fastened are. Really the only thing that wouldn't be "feeling" that force would be the object through which the centripedal acceleration is channeling, let's just say in a car it would be the tires(since they are the only object being acted upon by an outside force) which in turn affect the bolts, then the axles, then the chassis, then the seats/seatbelts/doors, and then in turn you. Even then though, the wheels would still be affected by the normal force of the bolts and the axles.

In summary, treat your tires well, they go through a lot for you.

There's so many things wrong with Mass Effect's physics you shouldn't even try to grasp it. If time is relevant to speed, how come Shepard isn't a LOT younger than say, people staying on a single planet their entire lives? No, Shepard ages with them. If Shepard and crew spent all the time they do in FTL, they would stay younger longer than stationary people.

@Clonedzero - I think that's a very valid complaint. Jeans make the man.

hmm, wrong. photons do not have mass, and yet they interact with matter all the time. the reason neutrinos are so difficult to observe is that they only interact through the weak interaction (and gravitation of course).
