Quantum physics gets spooky
ScienceNOW: This might be a rare case about which Einstein was wrong. More than 60 years ago, the great physicist scoffed at the idea that anything could travel faster than light, even though quantum mechanics had suggested such a condition. Now four Swiss researchers have brought the possibility closer to reality. Testing a concept called "spooky action at a distance"--a phrase used by Einstein in criticizing the phenomenon--they have shown that two subatomic particles can communicate nearly instantaneously, even if they are separated by cosmic distances.

I wonder if there is the possibility that the quantum entanglement effect is an illusion and that relativity theory is in no way violated? Could it be that so-called entangled particles have internal clocks that tick at the exact same speed even when the particles are traveling at different relativistic velocities? Perhaps each such would be entangled particle has an internal clock that somehow effects its ability to take on a certain state that is observation dependent and which is not effected all by relativistic time dilation, either in the special relativistic sense nor the general relativistic sense such as by gravitational field induced time dilation.
Einstein was so uncomfortable with the idea that spooky action at a distance could occur that perhaps we need to consider the concept of hidden quantum variables such as this idea for a universal time piece or clock within so-called entangled particles.
Either way, the physics should prove interesting to further investigate as well as the development of any new necessary paradigms to explain these fascinating experimental results.

I don't think that we should discard the thought of a particle being able to move faster then the speed of light. We have "entanglement" and also " super position" of a particle. In super position of a particle, it has been documented that a particle can be in more then one position at a time. It has been documented that when a particle is in " super position" it can be in up to 3000 different position's at the same time. When reading this I found it to be a impossibility. How could anything be in one, two, three thousand different places at once.
If something could move faster than the speed of light, say twice the speed of light, would it not look to us that it was in two places at the same time. Though Einstein wasn't necessarily wrong! Light, in the world we live in , is the fastest increment we know or can see. With super position, it gives the possibility that a particle may be able to move up to 3000 times the speed of light.
This might also help to explain " entanglement" over great distances. If a particle had the ability to move at such incredible speeds compared to the fastest speed we could see, then it would look like it was happening instantiously.
It seems that these particles or the field that this particle could move in would be close to " plank" length, and would probably be close to zero degree's kelvin. This would allow a frictionless environment, so as the particle acquired speed it would not gain friction and it's mass wouldn't increase.
