Via Phantom Soapbox: Speed of light violated, spooky action at a distance confirmed
Albert Einstein was famously uneasy with some of the consequences of quantum entanglement. If quantum mechanics were right, then a pair of entangled objects would behave as a single quantum system no matter how far apart the objects were. Altering the state of one of them should instantly alter the state of the second, with the change seemingly occurring faster than light could possibly travel between the two objects. This, Einstein argued, almost certainly had to be wrong.
Obviously caused by the higher levels of CO2 in the atmosphere.
So all that’s needed for FTL communications across great distances is a super cryogenic cooling plant every 30 meters from source to target.
They had one in the middle too, so every 15 meters.
The experiment does not demonstrate FTL communication and can’t be used to create an FTL communication system. It’s like two observers witnessing a coin toss and seeing the same result on both ends – heads, or tails. Because the two coins are entangled and are in a sense one quantum object. Until they are observed they are in a quantum superposition of states – neither heads nor tails. One observer makes a measurement and it becomes heads or tails for both.
FTL communication over long distances would violate the theory of relativity and create major causality problems.
IDK much about it, but I got the impression that the point of this experiment is that they’re not doing what you describe, that they’re actually able to manipulate the particle at one end and see it reproduced at the other.
The criticism I’ve heard of the experiment you describe is that the properties observed may be ‘preset’ in quantum entangled particles, and that all you’re observing is the inevitable progression of states that both particles will display at the same time and that there is no actual communication… just two identical trains running on identical tracks so to speak.
And somewhere an angel got it’s wings.
Since nobody can disprove it (see! here’s the numbers!), they’ll need a couple of million bucks more to do the next series of experiments.
Can’t wait to find out what’s racist regarding this study……
I don’t know about what’s racist in this study, but I found the sexist part: they used Helium instead of Shelium!
Oh there it is.
which is more likely, RNG data was transmitted over a distance at a speed greater than c or somewhere their math is wrong?
They never claimed to send data faster than c. Its just another example of re-hashing old proofs, or as modern physics calls it “closing the loopholes” in the Bell Inequality.
Physics, while not yet fallen to wokeness, is however just as hidebound as 20th century Egyptology.
Case in point: Ignoring Conformal Cyclic Cosmology, despite it being the only theory that actually has evidence for it in the CMB.
Thanks for the linkage Kate! ~:D
This entanglement thing, having now proven true (unless they just lied which is unlikely but not impossible), will shortly be rocking our world with a whole new level of computer processing. Once you know you can connect qbits at arbitrarily large distances, like 30 meters, it means that you don’t have to get everything on once piece of silicon. If you can keep the entire assembly at a superconducting temperature, you can run multiple chips feet away from each other and maintain your quantum superposition across all of them. No speed-of-light lag across the machine. That’s huge, right there.
It also opens the door to the possibility of FTL communication at arbitrarily large distances. Such as interplanetary probes or interstellar ones. Once you know you can do it, the rest is engineering.
“It also opens the door to the possibility of FTL communication“
No, it does not. See e.g. Dave’s comment above or Sabine H’ YouTube video on the topic.
Here is one pertaining Sabine H vid:

Sabine is a crank, more activist than physicist.
If Einstein were alive, he would be thrilled.
It’s no fun getting your quantums tangled. So stay away from the chicomm underwear at Mark’s Wearhouse.
Proving the Bell Inequality over a distance of 30 meters, in and of itself, in no way, shape or form provides an avenue for FTL communication.
Now, Susskind’s ER=EPR hypothesis about traversable wormholes and some of the work done by Google to make traversable wormholes out of entangled groups of qbits is another story altogether.
Let us make some assumptions.
1. God exists, and evolved within this universe into an essentially omniscient and omnipotent being.
2. God is capable of global violations of causality, being omnipotent and all.
3. God won’t like it if We can cause global violations of causality, because then We could then send signals back in time and abort God’s evolution.
4. God doesn’t like that.
5. If we manage to violate causality, we could literally face the wrath of God.
FTL com. = violation of causality.
Interesting times indeed.
Its like we live in a fragile fishbowl, and God doesn’t want us to smash it.
