Physicists Measure Speed of Einstein’s ‘Spooky Action at a Distance’: At Least 10,000 Times Faster Than Light

Posted March 07, 2013 8:56 AM

From ExtremeTech:

A team of Chinese physicists have clocked the speed of spooky action at a distance - the seemingly instantaneous interaction between entangled quantum particles - at more than four orders of magnitude faster than light. Their equipment and methodology doesn't allow for an exact speed, but four orders of magnitude puts the figure at around 3 trillion meters per second.

Spooky action at a distance was a term coined by Einstein to describe how entangled quantum particles seem to interact with each other instantaneously, over any distance, breaking the speed of light and thus relativity. As of our current understanding of quantum mechanics, though, it is impossible to send data using quantum entanglement, preserving the theory of relativity. A lot of work is being done in this area, though, and some physicists believe that faster-than-light communication might be possible with some clever manipulation of entangled particles.

Now, thanks to these Chinese physicists - the same ones who broke the quantum teleportation distance record last year - we know that spooky action at a distance has a lower bound of four orders of magnitude faster than light, or around 3 trillion meters per second. We say "at least," because the physicists do not rule out that spooky action is actually instantaneous - but their testing equipment and methodology simply doesn't allow them to get any more accurate.

What a pile of contradictory BS from reporters who know nothing about science and measurement and cannot even get their simple fact reporting straight.

Jack - For shame.

"Amen" to that ... ! How do they "Know" that they know what they (think) that they know ...?

"Now, thanks to these Chinese physicists ... we know that spooky action at a distance has a lower bound of four orders of magnitude faster than light, or around 3 trillion meters per second."

Hmmmm. Is that so ...? Have they really tried these (admittedly, VERY interesting) experiments over some TREMENDOUS DISTANCE ... say, between somewhere on earth and a "Moon_base"... while at the same time, including in the same experiment another likewise-entangled-particle at an even GREATER distance ...?

Perhaps , at this stage , resources/finances are the soul sole limiting factor ... (yet again, perhaps the first spelling was correct...)

For really Spooky Action, hand your wife $1000 and see how fast she spends it!

You're way too slow, she's already spent it before she grabs them from your hesitating hand.
