Sorry, Einstein. Quantum Study Suggests ‘Spooky Action’ Is Real.

John Markoff via NYTimes:

In a landmark study, scientists at Delft University of Technology in the Netherlandsreported that they had conducted an experiment that they say proved one of the most fundamental claims of quantum theory — that objects separated by great distance can instantaneously affect each other’s behavior.

The finding is another blow to one of the bedrock principles of standard physics known as “locality,” which states that an object is directly influenced only by its immediate surroundings. The Delft study, published Wednesday in the journal Nature, lends further credence to an idea that Einstein famously rejected. He said quantum theory necessitated “spooky action at a distance,” and he refused to accept the notion that the universe could behave in such a strange and apparently random fashion.

Might Quantum Pigeons be precognitive?

Via ScienceDaily:

Recently physicists at Chapman University’s Institute for Quantum Studies introduced the Quantum Cheshire Cat. Now they have introduced another quantum animal: the Quantum Pigeon.

In the 20th century, two revolutions in physics shook the world. One of them was relativity, discovered by Einstein. It revealed that spacetime is not what we experience in everyday life. For example, if you travel close to the speed of light, then you will age more slowly than somebody who stays on Earth.

The second revolution was quantum theory, the microscopic theory of particles, such as electrons, atoms, or photons. Quantum theory showed that nature is not deterministic. After a century of careful testing, most physicists believe that the “chanciness” or “capriciousness” of the microscopic world is fundamental.

One of the most exotic aspects of nature is quantum non-locality which was first discovered more than four decades ago.

Best Explanation of Quantum Field Theory That You Will Ever Hear

via chycho


Below you will find an excellent lecture by Dr. Sean Carroll delivered on 12 June 2013 at the 46th Annual Fermilab Users Meeting, focusing on the importance of the discovery of the Higgs boson confirming the existence of the Higgs field – giving us a glimpse into the world of “Particles, Fields and The Future of Physics”.

For me, the highlight of the lecture occurred during the question and answer period, at approximately 1:14:32, when one of the members of the audience asked the following question:

Question: “So, could you explain a bit more on measurement? You said that you have wave and it interacts with an entangled amount of waves and then pops out a particle, right?

I found the following response by Dr. Carroll to be the best description of quantum field theory that I have ever come across:

Sean Carroll: “Yes.
