Yeah, let's talk about Quantum Entanglement! I like that topic. One question, is it real or just sci-fy?


It's been proven, and it also proves that moving at the speed of light is possible at some level at least anyway.


Although it begets the question of whether quantum entaglement is trully an example of physics defying Einstein's special theory of relativity. I mean, is there really any "movement" or "transmission" involved or could it in effect be an example of a wormhole-type phenomenon?

Wait.... that crap is real? Wow.......


It's amazing what those Godless heathens who don't know what the hell they're talking about are able to accomplish, isn't it?


Well the thing about quantum entanglement is that, for example, two particles that are in a state of quantum entanglement achieve the same quantum states as the other.  If you look at one, and it has an "up" spin, the other will also have an "up" spin.  The two particles in this entanglement can be millions of light years away from each other but retain the same eigenstates and energy eigenvalues, and if one were to change millions of light years away from the other, the other would change instantaneously as well.  Unfortunately, this does not coincide with the transfer of information, which cannot happen faster than the speed of light.  All that happens is two particles, which are pretty much identical at that point, undergo the same changes at the same time to their states, but you couldn't actually transfer information.  

Sorry if that sounds a bit confusing, it's a tough thing to explain :pinched:

As some have pointed out there may be ways around it. Also note 90% of what we know in reguards to space travel and the like is scientific theory. Not Scientific Fact, or Law. And thus isn't but the best idea we have to work with. But can be renderd mute or wrong at a momments notice. In fact once it was Scientific theory that the moon was mainly a thick layer of dust, that prompt us to launch numerous probes to basically crash into the Moon and see if that was true or not.

We know it wasn't now. We know so little about our own planet nevermind the vastness of space. In fact FTL may very well be possible via a number of means. And short of Century Ships is the only way we'll ever explore space, so lets hope that theory is in correct, or one day all of humanity will die on this sad little mud ball.



the truth is we may not be taught the actual truth in science classes either. look up john lear and his comments about fftl and alien contact . he is former cia

I always try to keep an open mind on such things, as Benjamin Franklin, once said. "Believe none of what you hear and half of what you see." 

And he's not the only one to make such claims, several former astronauts and Soviet Military Personnal make very much the same claims.

So I was right, that sounds a lot like the technology TIM uses to communicate with Shepard.  I think it was something about oscillating the two particles, but if what I read from that article was correctly understood, changing one doesn't mean that the other changes (is this correct?  I'm bad at reading for new information, I need a teacher :innocent:).  Would be an interesting idea if it worked...and could be actually useful... for now I suppose we can just make do with cell phones.

I *think* that changing one particle does affect the other particle. However, that effect would seem random to the other particle. You wouldn't know that the change is because of the change to the first particle. So they would have to communicate to you that they changed the particle for you to know that the particle was changed.

Well, at least they got a bit of the science (possibly) right, perhaps their AIs could distinguish patterns or something. I wonder if it's even possible for us to test something like that with our current technology.

Theoretically, no. Physists seem really firm on that. 
 
However, there is a new theory that involves energy teleportation through quantum entanglement. Who knows, maybe that would allow some form of communication.

If I were to go back just 40 years ago and say I could talk to a person in Japan as if they were in the same room they would look me up for public safety.

The only thing thats for sure, is provided we all arn't dead or living like this is mad max, then I'm sure 200 years from now someone with a love of history will pick up a book or what passes for books at that time and remark at how stupid we were. Science has became too...lazy and about being a bigger Thomas Edison than the next guy (IE $$$). No one does any real research into FTL as that would cost money and is beyond out technological capability. Plus its eaiser to say what can't be done than to actully try it.

You know, I could have sworn Pwener brought this junk up himself, out of the blue.

As for FTL, there's no particular reason to think that it's possible. Except that we'd really, really, like to have it.

Completely hypothetical particle. It's in the same book as wormholes, string theory, alternate universes, and unicorns.

Did you just compare Wormholes and String Theory to alternate universes and unicorns? Now you're just harshin' on my science.
Side note: stop acting like science and religion are mutually exclusive. They're not, and you are moron if you think they are. This isn't a science v. relgion thread anyway. Can we just get back to telling the OP that he's an idiot please?


String theory is complete fantasy. It has no predictive value so it is the same as unicorns. Flame breathing unicorns even!  And I would never harsh on science. Image IPB

Okay, okay. But what about robot unicorns? I've always taken string theory as an explanation more than an absolute, sort of like gravity or evolution (I have my problems with the big bang theory, but that's a post for another thread). It's not really a thing you can touch or measure, it's really more like a placeholder for the "something that causes stuff" and an explanation for what it does. We can't really say why, only that it does. That's why string theory makes sense to me. Probing into the why goes into things we just can't answer right now, if we ever can. Why does matter exist at all? Where did it come from? Was it just here? Is sapience an evolutionary benifit or just pure chance? These aren't questions we can answer. We can speculate, but at the end of the day, that's all we're really doing. Right now, string theory is the best answer we have for why things are the way they are. At least that's the way I see it.
OT: A Mass Effect field is capable of raising the speed of light within itself. We still can't go faster than the speed of light, so we just changed the speed of light (see: futurama). Mass Relays create mass free corridors, essentially a doorway in space-time that a ship can fly through. Read the codex next time OP.

Everybody has theories. If we don't kill ourselves off in a spectacular manner maybe we'll figure something out.

Color me a hopeless romantic or a terrible scientific mind bent hopeless on superstitious nonsense, but folks said for the longest time that traveling faster than the speed of sound was impossible. Now we do it everyday. We've also learned that space does, in fact, curve and bend. In the end, there's a lot we don't know. Based on what we know today, it is impossible. Will it still be "impossible" based on what we learn tomorrow? Only tomorrow can tell.

This is the only thing that needs to be said.

I remember when Science used to be "The only certainty is uncertainty" people are just less able to deal with insecurities and things that aren't part of what they can see. And alot of so called Scientists are happy to jump on board for money. Or to reinforce that view....like they always have now that I think about it. Normally out of 1000's of them it seems maybe only a small handful did, or will do **** that matters or helps...

I'm not saying string theory doesn't make sense. From what I understand of it and from what I have read physists think of it, it makes good sense. But without predictive value, its not disprovable so it's not a real theory.  But it does rather blow your mind, I agree. I was just picking a fight is all. Image IPB

Tachyons, negative mass, warp drive, etc. All of this stuff is pure theory at this point. We just know that our math suggests they would allow FTL travel.

There has been a lot of research done since Eistein's original theory:

If a means can be found to overcome or cicumvent the energy requirements, it's possible.

None of what you listed has been deemed physically impossible.  It may have been impossible at the time to achieve it, but it was never called physically impossible.  Traveling faster than the speed of sound was once impossible because we didn't have the technology at the time to do it; physics at the time didn't disallow it.  Einstein's general relativity predicted the true nature of gravity as distortions in the spacetime fabric caused by the presence of mass.  It was simply a new way to describe one of the previously most well-studied forces.  The speed of light on the other hand, I think we can safely determine it to be impossible to travel at or exceed by normal physical convention.  For something to travel at the speed of light, it has to have infinite mass and energy, which is physically impossible.  The only way for something to travel faster than the speed of light is if it already had a negative mass/energy to begin with when it came into existence; that's where the idea of tachyons came into play, something with negative properties that therefore travels faster than the speed of light AND can never fall below the speed of light.  These, however, have not been proven to exist and I don't see how they could be observed anyways.

Enigma is right; that's what I was trying to say. These things, tachyons, negative energy/mass, and the like are pure math work. They have no say outside the paper and equations. Our math suggests that FTL travel would be possible with them, but that's as far as it gets. Will they ever come to reality? The world may never know, but I sure as hell hope to see something in my lifetime.

Maybe now it's kinda impossible, but who knows if it is still in couple of thousand years or even a couple of hundred years. Just look at the phase everthing is progressing. It's not like we know all there is to know about these things yet, would be quite arrogant to say that. Give us great scientists and time and we eventually figure it out.

Just saying.

I think their might be too much reliance on math to prove things.  I'm not saying everyone thinks math is always right, but there is a faction that does. Math has fallacies and humans had to give reason to support that hole.

In a couple thousand years, the human race is likely to be extinct.  Hopefully, they can come up with something long before that.  Hell, even a couple hundred years will probably be too late.

No one thinks that just because something is possible within the math that its true. That's why we have theoretical physics and experimental physics. The theorists propose things and the experimental physists try to make predictions using those theories and then test those predictions. If you can't make predictions and test them with a theory then its largely considered fanciful until it can be tested.
