ok so one of the things Mr. Albert Einstein talked about in his Teory of relativity was that if you were albe to travel with a speed close to the speed of light, or even faster, you would actually travel through time, since the time you experience is different from the time for those observing "you", thus traveling through time.

An exaple(random numbers) you be if you travel to a start with FTL speed. You say goodbye to your girl/boy-friend, and your journey takes 1 year to you, but when you get home, your soulmate has aged 10 years.
This means that you don't travel 100% back in time. You do travel forward in time, but slowlier then the rest of the world, so kind of "back in time" yet still forward, from the POV of the general mobe.

So actually if they DO travel with FTL speed in ME, which they are saying all the time, how are they able to compensate for that, and does this invoulve dimension theories?

hehe hope this gave you a bit to think about, bc to me, this seem like a big fail in the series actoually, if you look at it with an realistic POV =)

Mass Effect is fiction.



And concerning Einstein's theory: It's still a theory. So far no one we know off has been able to actually test it.

[candidate88766]

Firstly, its a science fiction game - it doesn't have to be perfectly correct

Secondly, i'm not sure that Einstein accounted for the (albiet fictional) ability to change an objects mass.

[Dominus]

I see where you're coming from, but as the previous 2 have mentioned, it's science fiction. C'est la vie. I give you points for effort though.

[Phaedon]

Einstein's theory is rather outdated, also, check the Alcubierre drive and wormholes.

A. I'm pretty sure that referring to it as "travel through time" is incorrect on even the most basic level as time dilation is not about time travel and is simply about the perception of passing of time being different.

B. Time dilation is the kind of physics headache that is generally best left for educated physicists and kept away from laymen unless you make a plot point out of it because it is, quite frankly, a very difficult concept to figure out and work with.

C. As candidate88766 states, Time dilation is affected by mass just as it's affected by velocity, and by being able to change the mass of objects (or even "create" mass for the Normandy's propulsion) will essentially either break relativity or do very, very strange things to it by default.

If you want to nitpick the ME universe, FTL travel is the least of your worries.

[Turbooggyboy]

As the Mass Effect core lowers the mass of the ship, the speed of light is essentially raised thus allowing for fast travel with relatively small effects of time dilation. At least according to fluff/codex entry.

[xentar]

Huh, give me an example of a setting where FTL is done RIGHT.

You can't "essentially raise" the speed of light by lowering the mass of a body (it would help it reach the speed of light easier, though).

I know. There is also talk about some kind of Mass Effect envelope. Probably similar to the warp field of the Star Trek universe. Though in Mass Effect the core is most certainly only allowing for this "envelope" to be created as the ships uses regular thrust for achieving speed.

What about objects of negative mass though? How do we know that they can't achieve FTL?
And yeah, negative mass is a speculative concept.

Mass Effect is science fiction (for the time being) and plus this is Einsteins theory and only a theory. To be honest I don't believe in that theory

[Spartas Husky]

Einstain is wrong... pretty much. Eistein explains only what we can understand at the moment.



1000 years ago nothing could go faster than a horse or boat. little over 100 years ago nothing was faster than a train.



Today we got the space shuttle. And at the rate of our current technological expantion we will surely come up with a higher speed limit than we got today. And at that pace we will break through that magic limit.

The whole idea is that FTL travel would have nothing to do with mass. So, they named the effect somewhat incorrectly.

Problem is, the examples from the past deal with technological limitations. Nothing prevented those speeds from being achieved but lack of power and efficiency. The speed of light is a theoretical limitation, so, it's trickier to circumvent. According to current knowledge, we can't achieve anything faster no matter how much power we apply.

Hmm, interesting. So, how was relative time addressed there? Such as an example when you travel 10 light years away in a day or so, send a near-instantaneous ftl communication to your point of origin and receive it 10 years ago?

[Lumikki]

Albert Einsteins teories is just one, there is also other teories, what aren't conflict to what Albert Einstein sayed. Example traveling from one to other place is about time AND distance what creates the traveling speed. What if the distance isn't solid value, but can be affected. Example folding space it self with gravity and creating gravity holes in space. This way two distance places could be connected and time would not be issue, because there is no distance between them.

Of course this is just science fiction as teories, but Albert Einstein teories aren't agaist this one. Can it be done, who knows, that's why they are called science teories. Science fiction frequently employs speculative concepts such as wormholes and hyperspace as more practical means of intergalactic travel to work around this speed of light issue.

The same thing was said less than 100 years ago about traveling faster than the speed of sound within earth's atmosphere in a manned aircraft.  Some theorists said that it would simply vibrate ANY vehicle apart and that it was a hard limit on atmospheric travel.  They even had models supporting this claim.  

What we see today as a hard cap may in fact just be a technological limitation that we have not yet recognized as such.

Wow youre right great points!

Dear Bioware, realism is the SOLE matter of import in video games. Please fix this MASSIVE fail in the game!!! From now on, in ME, you may only travel 99.9999% the speed of light. 

Phew! Good thing, the Reapers will never make it back now. Too bad we'll never make it back to Earth in our lifetime.

[Walker White]

Einsteins observations involve changing reference frames, not simply moving from A to B. There are wormhole theories that are consistent with Einstein.

We could make it there pretty quickly (in our reference frame) if acceleration is somehow negated.

[Had-to-say]

On the very cutting edge of particle science they have accelerated particles really close to the speed of light and it had a clone effect where the particles seem to be in two places at once. But I do believe we will find a way to make a mass vaccum. ( really large natural/artificial electromagnetic field) to zip through space similar to what is found in Mass Effect. Bullet trains are the first step in the right direction.

Hey I saw this on a Quantum communication forum and thought it was funny. This is really a joke for the really nerdy. Tell me if you get the joke. Quantum communication is the method TIM uses to talk to Shepard. Tell me if you find it funny.

The joke:

I don't know if this idea will work or not, but this is what I thought up. Let's say we make two boxes of particles so that each particle has it's entangled pair in the other box. Then fly one of the boxes to let's say mars. When you want to send some info to mars, you examine particles in your box here in earth. That way you also convert corresponding particles in mars to their determined state. The question is is it possible in mars to determine the interval of entanglement chances happening? If it is, then the interval can be used to encode information. Let's say 1 millisecond between changes is 1 and 2ms is 0. Or what ever is more suitable way to encode the information to those intervals. This will use up the entangled particle pairs, but given enough at beginning, it should not matter.

Introducing relativity would break most conventional sci fi settings. Since relativity changes so much, one would have to design a setting around relativity if the setting was to include relativity.
