Quantum Entanglement Verified: Why Space Is Just The Construct That Gives The Illusion Of Separate Objects

“Space is just the construct that gives the illusion that there are separate objects” – Dr. Quantum (see video below)There is a phenomenon so strange, so fascinating, and so counter to what we believe to be the known scientific laws of the universe, that Einstein himself could not wrap his head around it. It’s called “quantum entanglement,” though Einstein referred to it as “spooky action at a distance.”An [...]

Should Humanity Try to Contact Alien Civilizations?



Some researchers want to use big radio dishes like the 305-meter Arecibo Observatory in Puerto Rico to announce our presence to intelligent aliens.



Excerpt from space.com
by Mike Wall

Is it time to take the search for intelligent aliens to the next level?
For more than half a century, scientists have been scanning the heavens for signals generated by intelligent alien life. They haven't found anything conclusive yet, so some researchers are advocating adding an element called "active SETI" (search for extraterrestrial intelligence) — not just listening, but also beaming out transmissions of our own designed to catch aliens' eyes.

Active SETI "may just be the approach that lets us make contact with life beyond Earth," Douglas Vakoch, director of interstellar message composition at the SETI Institute in Mountain View, California, said earlier this month during a panel discussion at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Jose.

Seeking contact


Vakoch envisions using big radio dishes such as the Arecibo Observatory in Puerto Rico to blast powerful, information-laden transmissions at nearby stars, in a series of relatively cheap, small-scale projects.

"Whenever any of the planetary radar folks are doing their asteroid studies, and they have an extra half an hour before or after, there's always a target star readily available that they can shift to without a lot of extra slough time," he said.

The content of any potential active SETI message is a subject of considerable debate. If it were up to astronomer Seth Shostak, Vakoch's SETI Institute colleague, we'd beam the entire Internet out into space.

"It's like sending a lot of hieroglyphics to the 19th century — they [aliens] can figure it out based on the redundancy," Shostak said during the AAAS discussion. "So, I think in terms of messages, we should send everything."

While active SETI could help make humanity's presence known to extrasolar civilizations, the strategy could also aid the more traditional "passive" search for alien intelligence, Shostak added.
"If you're going to run SETI experiments, where you're trying to listen for a putative alien broadcast, it may be very instructive to have to construct a transmitting project," he said. "Because now, you walk a mile in the Klingons' shoes, assuming they have them."

Cause for concern?

But active SETI is a controversial topic. Humanity has been a truly technological civilization for only a few generations; we're less than 60 years removed from launching our first satellite to Earth orbit, for example. So the chances are that any extraterrestrials who pick up our signals would be far more advanced than we are. 

This likelihood makes some researchers nervous, including famed theoretical physicist Stephen Hawking.

"Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they could reach," Hawking said in 2010 on an episode of "Into the Universe with Stephen Hawking," a TV show that aired on the Discovery Channel. "If so, it makes sense for them to exploit each new planet for material to build more spaceships so they could move on. Who knows what the limits would be?"

Astrophysicist and science fiction author David Brin voiced similar concerns during the AAAS event, saying there's no reason to assume that intelligent aliens would be altruistic.

"This is an area in which discussion is called for," Brin said. "What are the motivations of species that they might carry with them into their advanced forms, that might color their cultures?"

Brin stressed that active SETI shouldn't be done in a piecemeal, ad hoc fashion by small groups of astronomers.

"This is something that should be discussed worldwide, and it should involve our peers in many other specialties, such as history," he said. "The historians would tell us, 'Well, gee, we have some examples of first-contact scenarios between advanced technological civilizations and not-so-advanced technological civilizations.' Gee, how did all of those turn out? Even when they were handled with goodwill, there was still pain."

Out there already

Vakoch and Shostak agreed that international discussion and cooperation are desirable. But Shostak said that achieving any kind of consensus on the topic of active SETI may be difficult. For example, what if polling reveals that 60 percent of people on Earth are in favor of the strategy, while 40 percent are opposed?

"Do we then have license to go ahead and transmit?" Shostak said. "That's the problem, I think, with this whole 'let's have some international discussion' [idea], because I don't know what the decision metric is."

Vakoch and Shostak also said that active SETI isn't as big a leap as it may seem at first glance: Our civilization has been beaming signals out into the universe unintentionally for a century, since the radio was invented.

"The reality is that any civilization that has the ability to travel between the stars can already pick up our accidental radio and TV leakage," Vakoch said. "A civilization just 200 to 300 years more advanced than we are could pick up our leakage radiation at a distance of several hundred light-years. So there are no increased dangers of an alien invasion through active SETI."

But Brin disputed this assertion, saying the so-called "barn door excuse" is a myth.

"It is very difficult for advanced civilizations to have picked us up at our noisiest in the 1980s, when we had all these military radars and these big television antennas," he said.

Shostak countered that a fear of alien invasion, if taken too far, could hamper humanity's expansion throughout the solar system, an effort that will probably require the use of high-powered transmissions between farflung outposts.

"Do you want to hamstring all that activity — not for the weekend, not just shut down the radars next week, or active SETI this year, but shut down humanity forever?" Shostak said. "That's a price I'm not willing to pay."

So the discussion and debate continues — and may continue for quite some time.

"This is the only really important scientific field without any subject matter," Brin said. "It's an area in which opinion rules, and everybody has a very fierce opinion."

Henry P. Stapp is a theoretical physicist at the University of California–Berkeley who worked with some of the founding fathers of quantum mechanics. He does not seek to prove that the soul exists, but he does say that the existence of the soul fits within the laws of physics.

He does not seek to prove that the soul exists, but he does say that the existence of the soul fits within the laws of physics.

It is not true to say belief in the soul is unscientific, according to Stapp. Here the word “soul” refers to a personality independent of the brain or the rest of the human body that can survive beyond death.  In his paper, “Compatibility of Contemporary Physical Theory With Personality Survival,” he wrote: “Strong doubts about personality survival based solely on the belief that postmortem survival is incompatible with the laws of physics are unfounded.”
He works with the Copenhagen interpretation of quantum mechanics—more or less the interpretation used by some of the founders of quantum mechanics, Niels Bohr and Werner Heisenberg. Even Bohr and Heisenberg had some disagreements on how quantum mechanics works, and understandings of the theory since that time have also been diverse. Stapp’s paper on the Copenhagen interpretation has been influential. It was written in the 1970s and Heisenberg wrote an appendix for it. 

Stapp noted of his own concepts: “There has been no hint in my previous descriptions (or conception) of this orthodox quantum mechanics of any notion of personality survival.”

Why Quantum Theory Could Hint at Life After Death

Stapp explains that the founders of quantum theory required scientists to essentially cut the world into two parts. Above the cut, classical mathematics could describe the physical processes empirically experienced. Below the cut, quantum mathematics describes a realm “which does not entail complete physical determinism.”

Of this realm below the cut, Stapp wrote: “One generally finds that the evolved state of the system below the cut cannot be matched to any conceivable classical description of the properties visible to observers.”

So how do scientists observe the invisible? They choose particular properties of the quantum system and set up apparatus to view their effects on the physical processes “above the cut.”

The key is the experimenter’s choice. When working with the quantum system, the observer’s choice has been shown to physically impact what manifests and can be observed above the cut. 

Stapp cited Bohr’s analogy for this interaction between a scientist and his experiment results: “[It's like] a blind man with a cane: when the cane is held loosely, the boundary between the person and the external world is the divide between hand and cane; but when held tightly the cane becomes part of the probing self: the person feels that he himself extends to the tip of the cane.”

The physical and mental are connected in a dynamic way. In terms of the relationship between mind and brain, it seems the observer can hold in place a chosen brain activity that would otherwise be fleeting. This is a choice similar to the choice a scientist makes when deciding which properties of the quantum system to study. 

The quantum explanation of how the mind and brain can be separate or different, yet connected by the laws of physics “is a welcome revelation,” wrote Stapp. “It solves a problem that has plagued both science and philosophy for centuries—the imagined science-mandated need either to equate mind with brain, or to make the brain dynamically independent of the mind.”
