Chinese Physicists Measure Speed of “Spooky Action At a Distance”
Physics arXiv Blog ^ | March 7, 2013 | Physics arXiv Blog

Posted on 03/07/2013 11:41:49 PM PST by Bobalu

Einstein railed against the possibility of spooky action at a distance because it violates relativity. Now Chinese physicists have clocked it traveling more than four orders of magnitude faster than light

Ummmm.....
7
Or is it 8 now with the Vostok bacterium?
Wondering why this is coming in a bunch like this. Usually there are several years or at lest months in between. Now all this in a matter of weeks. Why the speed up? What is going on?

At 4Xs the speed of light it will still take 15k years to get from one side of the galaxy to the other.

It’s not a speed, it’s an acceleration. And it is probably the same as the Speed of Gravity.

If E=MC^2, and if Gravity (G) is equal to the Energy of a Mass (i.e. G=E/M), then G=C^2.

Any bets that “spooky action at a distance” turns out to also be the acceleration (not speed!) C^2?!

Physicist John Bell proved such faster than light connections several decades ago.
The book “Quantum Reality,” written by Nick Herbert in 1985, gives a thorough description of Bell’s Theorem. According to Herbert, the connection between entangled atomic particles is “unmediated, unmitigated, and immediate.” IOW, Herbert goes with the “instantaneous” connection not the four orders of magnitude (admittedly a baseline) discussed in the article.
It’s not spooky because all quantum particles/waves have undergone phase entanglement. They are related.
Thus, the universe is non-local, and on at least some level (deep reality, perhaps,) we are all connected with each other and everything else.
Yes, it is fascinating, and because it is counter intuitive, it is difficult to understand.
I can’t claim that I get it.

I love the stuff.
Of course, I don’t understand it either..who does!?

It’s as if the universe was actually just data and we are trying to make sense of it as if it were actually physical and real... no time, space, mass, speed or even rules.
Perhaps it’s all just in the mind of God or something... maybe we are characters in a great dream.

Heh, what if we are just so ignorant today that all of this becomes a joke many years from now? Maybe all of this our math is just not wrong but way wrong. What if our ideas about space travel are so backward that it becomes just another wives tale (in the future of course). Maybe our whole perception of space and distances is just wrong!

Just a bit of food for thought...heh. The future holds many strange and wonderful things...

Four orders of magnitude is not 4X.
1 -> 10 is 1 order of magnitude.
1 -> 100 is two orders.
1 -> 1,000 is three.
1 -> 10,000 is four.

So that's ten thousand times the speed of light... (1 year) / 10,000 = 52.5948766 minutes, or about an hour.

The 25 nearest stars to our solar system lie in a range of 4.2 to 11.7 light years; so if we could travel that speed, we could get there in less than 12 hours.

They say the results are clear but do not measure the speed of spooky action directly. Instead, the results place a lower bound on how fast it must be. The answer is that it is at least four orders of magnitude faster than light, and may still turn out to be instantaneous, as quantum mechanics predicts.

I added the boldface. So spooky action at a distance is at least 10,000 times faster than light, and it may be instantaneous.

Amazing stuff.

Entanglement works not only over separated space but also over separated time. It's possible to not only communicate and modify objects at a distance, but also communicate and change both the past and future. Einstein said the past, present, and future occur simultaneously. It appears time and space as we perceive them are illusions and we are somehow part of a timeless spaceless eternity. It's spooky stuff.

Voyager 1 is 35 years old. Imagine if we launched a proper robotic probe with a proper engine on it. We would be able to find out which of these "earthlike" planets in our own interstellar neighborhood are truly suitable for colonization.

I'd sign up to found New America - no commies allowed.

"At 4X's the speed of light it will still take 15k years to get from one side of the galaxy to the other."

Not "4X the speed of light".....four ORDERS OF MAGNITUDE (10,000X) the speed of light. Makes those pesky photons look like aged and decrepit snails.

It may just be that the author of the headline is math-challenged, but 4 orders of magnitude would mean 1000x the speed of light. It's still gonna take a while to get from one side of the galaxy to another. Hell, it still would take a long time to travel between stars, but it is more or less doable at that speed, at least for nearby stars, i.e., those within 50 or so light years.

Well, you almost got it; four orders of magnitude is 10,000 times (in round figures). OneWingedShark puts it as 12 hours from one side of the galaxy to the other. Assuming (counter to quantum theory which this experiment does not claim to disprove) that the actual “speed” isn’t infinite.

Yeah, should have read the entire thread. Several people pointed that out.

10kc is pretty freaking fast!

Maybe; I seem to recall that the definition of 'warp' changed between TOS and TNG, certainly in Voyager.
Reason: I recall the Enterprise in TOS being hit with an energy wave traveling "Warp 20".
In TNG I don't recall any 10+ Warp speed (off the top of my head).
In Voyager they explicitly state there's a Warp 10 speed-limit, with 10 being equal to infinite speed.

So, they didn't measure it directly, but set up and experiment that could measure it, if it were 10,000 times or less, faster than the sol.

It's a similar situation trying to determine the diameter of an electron. They have no idea what diameter they are, but they've probed to the extent that our technology is currently capable, and it's still smaller than that.

Given "the Milky Way is roughly 34 kpc (110,000 light-years) across", [Source] it would take 11 years* to traverse the Galagy edge-to-edge (w/ straight-line travel), so that's really not too bad.

* -- 110,000 Light-Years (10,000 Light) = 11 Years.

Could it be that traveling via some higher dimension(s) the distance is only 1/10,000 as far (or less)? In other words, the standard lower dimensions take a really roundabout path to get there.

Wouldn’t it be something if, as viewed through higher dimensions, that all points in the universe were adjacent to one another, or better yet, superimposed? The ultimate unity.

That wouldn’t surprise me at all truthfully. One avenue of thought is that mind can be anywhere at all instantly. Of course that doesn’t take the body to the far end of the universe but given how unfriendly most of it out there is to squishy little bags of water that’s probably for the best.

With a properly outfitted ship it might be kind of cool to spend your life flying out as far as you can get. I wouldn't count on finding a habitable planet though. Not based on today's data. Might not be too long before our intel is better though.

Nope, still wrong; at a width of 110,000 light-years, traversal of the Milky Way would take only 11 years traveling at a speed of 10,000 times that of light.
See here.

Yes, I dropped a decimal point and divided by 1k instead of 10k. I also used 65k light years for the diameter of our galaxy.

Here’s anothher half-stick.

You’ll appreciate how fantastically incriminating the early internet - before anonymizers, proxies and spoofers - was.

The time point when Norman ASA was committing heavy data crime on the net and didn’t understand their own footprints was a little later than this.
