As if the idea ideas of quantum entanglement and time travel weren’t difficult enough to wrap one’s head around separately, two physicists at the Universtiy of Queensland in Australia have further compounded the headache by merging the two ideas via a new kind of quantum entanglement that links particles not across space, but across time.
Quantum entanglement is that “spooky action” (Einstein’s words, not ours) that links two particles such that a measurement on one immediately influences the state of the other, even if the two particles are separated by miles, or even light years. Entanglement defies the intuitive way we understand the universe to work (as does most of quantum mechanics). The idea of “time teleportation,” as described by S. Jay Olson and Timothy Ralph, doesn’t add clarity but it does introduce some interesting questions about the fundamentals of the universe.
In a sense, everyone and everything is time traveling, moving forward in time at a given rate. What Olson and Ralph propose is that it’s possible to take a shortcut into the future without being present in the interim. How? Tech Review’s KFC explains:
The idea is that a detector acts on a qubit and then generates a classical message describing how this particle can be detected. Then, at some point in the future, another detector at the same position in space, receives this message and carries out the required measurement, thereby reconstructing the qubit.

Spooky electron read for later. Thanks.
Apparently KFC has all kinds of secrets locked up.
Wondering if this is how John Titor did it....
Hmmm... last week Univ of Queensland was underwater from the floods in Brisbane. There’s something fishy to all this.
kind of niggling isn’t it?
>> In a sense, everyone and everything is time traveling, moving forward in time at a given rate.
Not to imply a universal time domain.
All equally important events to be sure.

So it doesn't matter that the distant galaxies aren't blurry?
Do I hear the Longoliers?
May be seventy or eighty years ago if some one would have suggested flat panel TV’s, digital cameras, hand held communications devices now known as cell phones, copy machines, sending space probes to the far reaches of our universe or heaven forbid a computers in many homes and those ideas would have been exposed to a forum of readers as we see here, we probably would have been treated to similar rather brilliant comments, putting it mildly, as we find them here.
Most discoveries or concepts start with an idea and many of such ideas eventually become reality. If the human mind can conceive it we should not be surprised if some day we will see it transformed in to reality.
I am still in possession of a book dealing with scientific discoveries at the time and remember distinctly that about two pages were entirely devoted to the subject, why a fictitious thing such as a death ray never could be possible. And on top of it was written by some one who had more than one PhD. to his name. Never say never as chances are better than good that in time you may be proven wrong.
What matters is that an extremely small value isn't infinitely small. It's just really small. Zeno's paradox and all.
yeah, you’re right!....

Why aren’t they blurry?
