Thanks for your thoughts...

And....yes, OP means "Original Post"

P.S. where is the OP anyways....haven't heard nothing in a couple pages

On May 16, a Chinese team reported success with "teleportation" via quantum entanglement of photons at a distance of 16 km. Their report is available for $18 from Nature Photonics.

See other media hoopla on the subject.

If they have achieved actual FTL communication, my experiment should be next.

The Wikipedia page lists more ether experiments.

This would pull us into higher and higher orbits and eject us from the vicinity of the sun in a fairly short time.

Nope. The Sun's gravity is already in place.

When you take this fact into consideration, there is no barn paradox.

I don't see why that matters. Perhaps if you explain it in detail.

It's not a defeatist attitude; suppose you find the cause of gravity; then what? what causes the cause of gravity?

As you can see, the amount of questions that can be posed is infinite.

I never meant that darkness is an object or it consists of something.

Perhaps a better definition is this:

the rate of change from light to darkness is defined by the speed of light.

However, said teleportation is not actual teleportation and cannot be applied to macroscopic objects.

OK, so the speed of light is the speed of light, but isn't that circular and just plain silly? Your still attempting to describe a state of absence as a thing that can be acted upon by light. Darkness is just an absence, there is no rate of change with darkness. It doesn't exist as anything that *can* change.

Which is precisely why I put teleportation between quotation marks. They're sensationalizing their report by applying the word, "teleportation" to a quantum bit of information. Not even the energy is transferred at superluminal speed.

I am sorely tempted to click "ignore" for the first time since jointing ATS. Please stop arguing with yourself over this trivial matter, and get back to the topic at hand.

Oh I'm sorry, I wasn't aware the topic of this thread was about FTL communication.

Yea, how about *WE* get back on topic about the speed of gravity?

Moron.

Quantum entanglement is not that far off topic.

If FTL communication via quantum entanglement is as fast as it is purported to be, then it probably has the same speed as gravity. As the original post showed, Van Flandern calculated that speed to be greater than 20 billion c. This is practically indistinguishable from instantaneous. In other words, the sending and receiving are practically simultaneous events.

Relativity tells us that which is simultaneous in one reference frame cannot be simultaneous in another reference frame. Both quantum entanglement and gravity must have a certain finite speed in all directions relative to the ether. In all other reference frames, they have different speeds in different directions.

It is claimed that FTL communication has been achieved via quantum entanglement. If so, it can be used to prove the existence of the ether. It can prove that that the ether is a preferred reference frame for both quantum entanglement and for gravity.

If gravity has different speeds in different direction for a galaxy moving thru the ether, what are the implications? Can that somehow account for galaxy rotation curves? How will that knowledge affect our estimates of dark matter?

Nevertheless, I shall look for a thread on the subject of quantum entanglement and FTL communication. If I don't find one, I might start my own. Perhaps there is a thread out there on the subject of the speed of dark, as well.

It's two separate unrelated topics.

Probably has? Get back to me when you have more concrete evidence rather than pure conjecture. This thread isn't about your views of FTL communication, so how about you think before you get on someone else for also discussing an unrelated topic?

As the original post showed, Van Flandern calculated that speed to be greater than 20 billion c.

Right, as the OP discussed, *the speed of gravity*.

This is practically indistinguishable from instantaneous.

Yea, if your within a 5BLY radius of the sending station. Instantaneous is not really really fast if within range, so let's not use sensationalized terminology to describe something that is only conjecture and unproven.

In other words, the sending and receiving are practically simultaneous events.

Try telling that to two people on opposite ends of the universe. That's only a 156BLY distance between the two. Signals would have a delay of roughly 8 seconds, rounding up of course. That would kind of tick me off if your selling me a communications device that is purportedly 'instantaneous' or nearly indistinguishable.

Both quantum entanglement and gravity must have a certain finite speed in all directions relative to the ether.

You don't really understand Quantum Entanglement that well do you? There is no speed of communication at all. There is no carrier signal dispensing information about the other particles state. You can't even send information through Quantum Entanglement. It's all utterly moot to the speed of gravity.

It is claimed that FTL communication has been achieved via quantum entanglement.

Sources, as this would defy physics and we would need a complete rewrite.

It's not silly. The change from light to darkness is an event. The discussion drifted to this due an analogy with gravity: when matter goes absent, gravity goes absent too.

The rate of the change from gravity to absence of gravity is the speed of light, just like for the change from darkness to light.

If an object like the Sun was removed instantly from the universe, then we would feel the sun's gravity for 8 minutes. We would also see the Sun for 8 minutes.

If gravity change was instantaneous, we would feel the Sun was absent but we would see the Sun until 8 minutes passed. This would open the door paradoxes.
