Physicist Tested Particle Actions

By WALTER SULLIVAN Published: October 10, 1990

John Stewart Bell, whose test for one of the most bizarre aspects of quantum physics led to its apparent confirmation, died last week at a hospital in Geneva. He was 62 years old. Continue reading CERN Scientist -dead at 62

Scientists Report Finding Reliable Way to Teleport Data

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

Trap Doors in Time and Space: Teleportation, Time Travel, and Escape from Black Holes

Do you feel stuck in space and time? Do you want to fast forward to the future, replay the past—be anywhere but here and anywhen but now? Does your work situation seem like a black hole, sucking you remorselessly towards a point where your consciousness is squished into nothingness along with all the known laws of physics? I’m with you on all counts, if only because this article was due last week! Continue reading Trap Doors in Time and Space: Teleportation, Time Travel, and Escape from Black Holes

Spooky Action at a Distance

By Brian Greene Posted 09.22.11

Every age develops its stories or metaphors for how the universe was conceived and structured. According to an ancient Indian creation myth, the universe was created when the gods dismembered the primordial giant Purusa, whose head became the sky, whose feet became the Earth, and whose breath became the wind. To Aristotle, the universe was a collection of 55 concentric crystalline spheres, the outermost being heaven, surrounding those of the planets, Earth and its elements, and finally the seven circles of hell.

In 1947, eight years before his death, Einstein wrote to a friend that he could not seriously believe in quantum mechanics because “physics should represent a reality in time and space, free from spooky actions at a distance.” He was referring to quantum entanglement, one of the quantum world’s most bizarre attributes.

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

In a landmark study, scientists at Delft University of Technology in the Netherlands reported 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.
