Over what distance can quantum entanglement remain instantaneous?

Asked by ETpro (34472points) February 23rd, 2010

We know that once quantum particles become entangled, one reacts instantaneously when the other is disturbed. How far apart can this apparent Faster Than Light (FTL) reaction stretch. Do large masses obeying mass attraction exhibit the same level of entanglement, or does gravity stay below the speed limit© of the universe? If any FTL effect is possible, how does this not violate the Causal Ordering Postulate—the Universal Spped COP?

The space in which entanglement remains instantaneous is limitless. All things are connected by the ether, zero point field, collective consciousness, or whatever you want to call it, it is there, it is everywhere. Therefore, light is impeded by this medium. Ever wonder why there is a speed of light anyway? If this is the fastest measured speed, what causes light to not go any faster? The answer is this medium that connects everything. Space is a misnomer. Space is not empty. What is the speed of gravity? Not the acceleration rate but the speed at which gravitational waves travel. How do you measure this? Gravitational effects from the moon and sun are felt on the earth. We can see this with the tides and weather patterns globally. So how long do changes in the moon’s and sun’s gravitational fields take to affect the earth? Is it faster or slower than light? Common sense would dictate that it is slower, but is it really? Do we have any way of measuring this accurately?

My race has the answers to all of these questions. Unfortunately for you, before I was sent here my bosses wiped my memory of many things. They did this because you have to figure it out on your own. If we give your race anymore of our technology we are afraid that you will want to go to war with the galaxy. You don’t want to do this. It will only turn out very bad for you. We want your race to grow and become enlightened before we give any more assistance. We’ve been burned in the past, The Atom Bomb, Integrated circuits, Roswell (I want my ship back!), George Bush (He said he wouldn’t blow up the towers, stupid cokeheads!), B2, F117, SR-71, polyester, nylon, rayon, the list goes on and on… So get to work humans! You can do it! Start rethinking your current models of the universe and try using your imagination more, after all your thoughts are much more of the universe than you realize.

Ha! The speed of gravitational effect is just what I was getting at. Thanks for an incredibly interesting way of answering without answering. More fun than just giveing a number.

It occurred to me that we can see the speed with which gravitaional effects propogate by watching saturn’s moons set up interference patterns in the otherwise relatively stable dynamical system of Saturn’s ring particles.

How does one define instantaneous? What appears “instantaneous” in one inertial reference frame generally does not appear instantaneous in a different inertial reference frame, which is why we’ve abandoned the concept of absolute time for relativity. Instantaneous in all reference frames?

@hiphiphopflipflapflop Yes, i meant it as in a God’s eye view of instantaneous.

Let’s say I have a dear friend vacationing in the Andromeda Galaxy, If I ring her up on the quantum entanglement telephone, how much delay should I expect from asking her how Andromeda is to getting her answer back here on Earth?

There is no “God’s eye view” in special relativity. No privileged reference frame.

Perhaps I should have been more sensitive to your belief system. I used the word figuratively. Can we set that reference aside and just answer based on the thought experiment about my telecon with my sweetie vacationing in the Andromeda Galaxy? :-)
