Time and Space Are Not What You Think


Time and Space Are Not What You Think
Mind-Altering Quantum Experiment Shows Time Has Never Existed As We Think It Does

time






In 2012 US National Medal of Science award winner Yakir Aharonov, who is regarded as one of the world’s leading quantum theorists published a paper in Nature Physics showing that the present is constrained by the past and the future. This means that what happens in the present can depend on what happened in the future, which makes no sense, as quantum physics rarely does. It also means that what happened in the past can effect the present. Seems strange, doesn’t it?  It’s definitely something hard to wrap your head around.

“We choose to examine a phenomenon which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery.” Richard Feynman, a Nobel laureate of the twentieth century (Radin, Dean. Entangled Minds: Extrasensory Experiences In A Quantum Reality. New York, Paraview Pocket Books, 2006)

This isn’t the first time quantum physicists have studied the structure of time. Below are details of an experiment, the same one mentioned in the paper cited above.

 

Delayed Choice/Quantum Eraser/Time

 

 

There is another groundbreaking, weird experiment that also has tremendous implications for understanding the nature of our reality, more specifically, the nature of what we call “time.”

It’s known as the “delayed-choice” experiment, or “quantum eraser,” and it can be considered a modified version of the double slit experiment.

To understand the delayed choice experiment, you have to understand the quantum double slit experiment.

In this experiment, tiny bits of matter (photons, electrons, or any atomic-sized object) are shot towards a screen that has two slits in it. On the other side of the screen, a high tech video camera records where each photon lands. When scientists close one slit, the camera will show us an expected pattern, as seen in the video below. But when both slits are opened, an “interference pattern” emerges – they begin to act like waves.

This doesn’t mean that atomic objects are observed as a wave (even though it recently has been observed as a wave), they just act that way. It means that each photon individually goes through both slits at the same time and interferes with itself, but it also goes through one slit, and it goes through the other. Furthermore, it goes through neither of them. The single piece of matter becomes a “wave” of potentials, expressing itself in the form of multiple possibilities, and this is why we get the interference pattern.

How can a single piece of matter exist and express itself in multiple states, without any physical properties, until it is “measured” or “observed?” Furthermore, how does it choose which path, out of multiple possibilities, it will take?

Then, when an “observer” decides to measure and look at which slit the piece of matter goes through, the “wave” of potential paths collapses into one single path. The particle goes from becoming, again, a “wave” of potentials into one particle taking a single route. It’s as if the particle knows it’s being watched. The observer has some sort of effect on the behavior of the particle.

You can view a visual demonstration/explanation of the double slit experiment here.

This quantum uncertainty is defined as the ability, “according to the quantum mechanic laws that govern subatomic affairs, of a particle like an electron to exist in a murky state of possibility — to be anywhere, everywhere or nowhere at all — until clicked into substantiality by a laboratory detector or an eyeball.” (New York Times)

According to physicist Andrew Truscott, lead researcher from a study published by the Australian National University, the experiment suggests that “reality does not exist unless we are looking at it.” It suggests that we are living in a holographic-type of universe. (source)

 

Delayed Choice/Quantum Eraser/Time

 

So, how is all of this information relevant to the concept of time? Just as the double slit experiment illustrates how factors associated with consciousness collapse the quantum wave function (a piece of matter existing in multiple potential states) into a single piece of matter with defined physical properties (no longer a wave, all those potential states collapsed into one), the delayed choice experiment illustrates how what happens in the present can change what happens(ed) in the past. It also shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past.

Like the quantum double slit experiment, the delayed choice/quantum eraser has been demonstrated and repeated time and time again. For example, Physicists at The Australian National University (ANU) have conducted John Wheeler’s delayed-choice thought experiment, the findings were recently published in the journal Nature Physics. (source)

In 2007 (Science 315, 966, 2007), scientists in France shot photons into an apparatus and showed that their actions could retroactively change something which had already happened.

“If we attempt to attribute an objective meaning to the quantum state of a single system, curious paradoxes appear: quantum effects mimic not only instantaneous action-at-a-distance, but also, as seen here, influence of future actions on past events, even after these events have been irrevocably recorded.” – Asher Peres, pioneer in quantum information theory (source)(source)(source)

The list literally goes on and on, and was first brought to the forefront by John Wheeler, in 1978, which is why I am going to end this article with his explanation of the delayed choice experiment. He believed that this experiment was best explained on a cosmic scale.

 

Cosmic Scale Explanation

 


He asks us to imagine a star emitting a photon billions of years ago, heading in the direction of planet Earth. In between, there is a galaxy. As a result of what’s known as “gravitational lensing,” the light will have to bend around the galaxy in order to reach Earth, so it has to take one of two paths, go left or go right. Billions of years later, if one decides to set up an apparatus to “catch” the photon, the resulting pattern would be (as explained above in the double slit experiment) an interference pattern. This demonstrates that the photon took one way, and it took the other way.

One could also choose to “peek” at the incoming photon, setting up a telescope on each side of the galaxy to determine which side the photon took to reach Earth. The very act of measuring or “watching” which way the photon comes in means it can only come in from one side. The pattern will no longer be an interference pattern representing multiple possiblities, but a single clump pattern showing “one” way.

What does this mean? It means how we choose to measure “now” affects what direction the photon took billions of years ago. Our choice in the present moment affected what had already happened in the past….

This makes absolutely no sense, which is a common phenomenon when it comes to quantum physics. Regardless of our ability make sense of it, it’s real.

This experiment also suggests that quantum entanglement (which has also been verified, read more about that here) exists regardless of time. Meaning two bits of matter can actually be entangled, again, in time.

Time as we measure it and know it, doesn’t really exist.


Reality Doesn’t Exist Until We Measure it: Quantum Experiment Confirms

weird


Last year, Australian scientists replicated a classic  experiment confirming  that reality doesn’t actually exist until we measure it, that is, at the quantum level.

“It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,” lead researcher and physicist Andrew Truscott said in a press release.

The replicated experiment is known John Wheeler’s delayed-choice thought experiment, the experiment was first proposed back in 1978 using light beams bounced by mirrors, but back then, the technology needed was pretty much impossible. Now, almost 40 years later, the Australian team has managed to recreate the experiment using helium atoms scattered by laser light.

The delayed choice experiment illustrates how what happens in the present can change what happens(ed) in the past. It also shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past. We published an article that goes into detail about it, and you can read that here.

Quantum physics predictions about interference seem odd enough when applied to light, which seems more like a wave, but to have done the experiment with atoms, which are complicated things that have mass and interact with electric fields and so on, adds to the weirdness,” said Roman Khakimov, a PhD student who worked on the experiment.

To  recreate the experiment, researchers  team trapped a bunch of helium atoms in a suspended state known as a Bose-Einstein condensate, and then ejected them all until there was only a single atom left.

The chosen atom was then dropped through a pair of laser beams, which made a grating pattern that acted as a crossroads that would scatter the path of the atom, much like a solid grating would scatter light. After that, researchers randomly added a second grating that recombined the paths, but only after the atom had already passed the first grating.

When this second grating was added, it led to destructive interference, which is what you’d expect if the atom had travelled both paths, like a wave would. But when the second grating was not added, no interference was observed, as if the atom chose only one path.

The fact that this second grating was only added after the atom passed through the first crossroads suggests that the atom hadn’t yet determined its nature before being measured a second time.

So, if you believe that the atom did take a particular path or paths at the first crossroad, this means that a future measurement was affecting the atom’s path.


“The atoms did not travel from A to B. It was only when they were measured at the end of the journey that their wave-like or particle-like behaviour was brought into existence,”
– Andrew Truscott

“This quantum uncertainty is defined as the ability, “according to the quantum mechanic laws that govern subatomic affairs, of a particle like an electron to exist in a murky state of possibility — to be anywhere, everywhere or nowhere at all — until clicked into substantiality by a laboratory detector or an eyeball.” (New York Times)

Another potential revelation of this experience is that “the observer creates the reality.”  Because it is a form of measuring, and a factor associated with consciousness. A paper published in the peer-reviewed journal Physics Essays by Dean Radin, PhD, explains how this experiment has been used multiple times to explore the role of consciousness in shaping the nature of physical reality. (source)

In this experiment, a double-slit optical system was used to test the possible role of consciousness in the collapse of the quantum wave-function. The ratio of the interference pattern’s double slit spectral power to its single slit spectral power was predicted to decrease when attention was focused toward the double slit as compared to away from it. The study found that factors associated with consciousness “significantly” correlated in predicted ways with perturbations in the double slit interference pattern. (source)

“Observation not only disturbs what has to be measured, they produce it. We compel the electron to assume a definite position. We ourselves produce the results of the measurement.” (source)

I’ll leave you with this one last quote to give you something to think about

“A fundamental conclusion of the new physics also acknowledges that the observer creates the reality. As observers, we are personally involved with the creation of our own reality. Physicists are being forced to admit that the universe is a “mental” construction. Pioneering physicist Sir James Jeans wrote: “The stream of knowledge is heading toward a non-mechanical reality; the universe begins to look more like a great thought than like a great machine. Mind no longer appears to be an accidental intruder into the realm of matter, we ought rather hail it as the creator and governor of the realm of matter. Get over it, and accept the inarguable conclusion. The universe is immaterial-mental and spiritual.”
– R.C. Henry, Professor of Physics and Astronomy at Johns Hopkins University , “The Mental Universe” ; Nature 436:29,2005)

Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone

Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone
  http://fractalartgallery.com/gallery/58/manyworlds30.jpg
Recent discoveries require us to rethink our understanding of history. “The histories of the universe,” said renowned physicist Stephen Hawking “depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history."
Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future -- and may even depend on actions that you haven't taken yet.
In 2002, scientists carried out an amazing experiment, which showed that particles of light (photons) knew -- in advance what their distant twins would do in the future. They tested the communication between pairs of photons to determine whether they were either a wave or a particle. Researchers stretched the distance one of the photons had to take to reach its detector, so that the other photon would hit its own detector first. The photons taking this path already finished their journeys they either collapse into a particle or don't before their twin encounters a scrambling device.
Somehow, the particles acted on this information before it happened, and across distances instantaneously as if there was no space or time between them. They decided not to become particles before their twin ever encountered the scrambler. It doesn't matter how we set up the experiment. Our mind and its knowledge is the only thing that determines how they behave. Experiments consistently confirm these observer-dependent effects.

More recently (Science 315, 966, 2007), scientists in France shot photons into an apparatus, and showed that what they did could retroactively change something that had already happened. As the photons passed a fork in the apparatus, they had to decide whether to behave like particles or waves when they hit a beam splitter. Later on - well after the photons passed the fork - the experimenter could randomly switch a second beam splitter on and off. It turns out that what the observer decided at that point, determined what the particle actually did at the fork in the past. At that moment, the experimenter chose his history.

Of course, we live in the same world. Particles have a range of possible states, and it's not until observed that they take on properties. So until the present is determined, how can there be a past? According to visionary physicist John Wheeler (who coined the word "black hole"), "The quantum principle shows that there is a sense in which what an observer will do in the future defines what happens in the past." Part of the past is locked in when you observe things and the "probability waves collapse."
But there's still uncertainty, for instance, as to what's underneath your feet. If you dig a hole, there's a probability you'll find a boulder. Say you hit a boulder; the glacial movements of the past that account for the rock being in exactly that spot will change as described in the Science experiment.

But what about dinosaur fossils? Fossils are really no different than anything else in nature. For instance, the carbon atoms in your body are "fossils" created in the heart of exploding supernova stars. Bottom line: reality begins and ends with the observer. "We are participators," Wheeler said "in bringing about something of the universe in the distant past." Before his death, he stated that when observing light from a quasar, we set up a quantum observation on an enormously large scale. It means, he said, the measurements made on the light now, determines the path it took billions of years ago.

Like the light from Wheeler's quasar, historical events such as who killed JFK, might also depend on events that haven't occurred yet. There's enough uncertainty that it could be one person in one set of circumstances, or another person in another. Although JFK was assassinated, you only possess fragments of information about the event. But as you investigate, you collapse more and more reality. According to biocentrism, space and time are relative to the individual observer, we each carry them around like turtles with shells.
History is a biological phenomenon it's the logic of what you, the animal observer experiences. You have multiple possible futures, each with a different history like in the Science experiment. Consider the JFK example: say two gunmen shot at JFK, and there was an equal chance one or the other killed him. This would be a situation much like the famous Schrödinger's cat experiment, in which the cat is both alive and dead both possibilities exist until you open the box and investigate.
"We must re-think all that we have ever learned about the past, human evolution and the nature of reality, if we are ever to find our true place in the cosmos," says Constance Hilliard, a historian of science at UNT. Choices you haven't made yet might determine which of your childhood friends are still alive, or whether your dog got hit by a car yesterday. In fact, you might even collapse realities that determine whether Noah's Ark sank. "The universe," said John Haldane, "is not only queerer than we suppose, but queerer than we can suppose."

Rewriting the Past

"I don't believe in yesterday, by the way."
-John Lennon

The past is set in stone, right?  Everything we have learned tells us that you can not change the past, 88-MPH DeLoreans notwithstanding.  However, it would probably surprise you to learn that many highly respected scientists, as well as a few out on the fringe, are questioning that assumption, based on real evidence.
For example, leading stem cell scientist, Dr. Robert Lanza, posits that the past does not really exist until properly observed.  His theory of Biocentrism says that the past is just as malleable as the future.
Specific experiments in Quantum Mechanics appear to prove this conjecture.  In the "Delayed Choice Quantum Eraser" experiment, "scientists in France shot photons into an apparatus, and showed that what they did could retroactively change something that had already happened." (Science 315, 966, 2007)
Paul Davies, renowned physicist from the Australian Centre for Astrobiology at Macquarie University in Sydney, suggests that conscious observers (us) can effectively reach back in history to "exert influence" on early events in the universe, including even the first moments of time.  As a result, the universe would be able to "fine-tune" itself to be suitable for life.
Prefer the Many Worlds Interpretation (MWI) of Quantum Mechanics over the Copenhagen one?  If that theory is correct, physicist Saibal Mitra from the University of Amsterdam has shown how we can change the past by forgetting.  Effectively if the collective observers memory is reset prior to some event, the state of the universe becomes "undetermined" and can follow a different path from before.  Check out my previous post on that one [reposted below].
Alternatively, you can disregard the complexities of quantum mechanics entirely.  The results of some macro-level experiments twist our perceptions of reality even more.  Studies by Helmut Schmidt, Elmar Gruber, Brenda Dunne, Robert Jahn, and others have shown, for example, that humans are actually able to influence past events (aka retropsychokinesis, or RPK), such as pre-recorded (and previously unobserved) random number sequences
Benjamin Libet, pioneering scientist in the field of human consciousness at  the University of California, San Francisco is well known for his controversial experiments that seem to show reverse causality, or that the brain demonstrates awareness of actions that will occur in the near future.  To put it another way, actions that occur now create electrical brain activity in the past.
And then, of course, there is time travel.  Time travel into the future is a fact, just ask any astronaut, all of whom have traveled nanoseconds into the future as a side effect of high speed travel.  Stephen Hawking predicts much more significant time travel into the future.  In the future.  But what about the past?  Turns out there is nothing in the laws of physics that prevents it.  Theoretical physicist Kip Thorne designed a workable time machine that could send you into the past.  And traveling to the past of course provides an easy mechanism for changing it.  Unfortunately this requires exotic matter and a solution to the Grandfather paradox (MWI to the rescue again here).
None of this is a huge surprise to me, since I question everything about our conventional views of reality.  Consider the following scenario in a massively multiplayer online role playing game (MMORPG) or simulation.  The first time someone plays the game, or participates in the simulation, there is an assumed "past" to the construct of the game.  Components of that past may be found in artifacts (books, buried evidence, etc.) scattered throughout the game.  Let's say that evidence reports that the Kalimdors and Northrendians were at war during year 1999.  But the evidence has yet to be found by a player.  A game patch could easily change the date to 2000, thereby changing the past and no one would be the wiser.  But, what if someone had found the artifact, thereby setting the past in stone.  That patch could still be applied, but it would only be effective if all players who had knowledge of the artifact were forced to forget.  Science fiction, right?  No longer, thanks to an emerging field of cognitive research.  Two years ago, scientists were able to erase selected memories in mice.  Insertion of false memories is not far behind.  This will eventually perfected, and applied to humans.
At some point in our future (this century), we will be able to snort up a few nanobots, which will archive our memories, download a new batch of memories to the starting state of a simulation, and run the simulation.  When it ends, the nanobots will restore our old memories. 

Or maybe this happened at some point in our past and we are really living the simulation.  There is really no way to tell.

No wonder the past seems so flexible.

Change the Past, Change the Future Simply by Forgetting

Here's an interesting idea.  To avoid an impending disaster, all you have to do is forget your past.  So says physicist Saibal Mitra at the University of Amsterdam.  Even changing the past seems to be possible, believe it or not.

His idea is predicated on accepting our old friend, the Everett interpretation of Quantum Mechanics, aka the Many Universes theory.  According to Mitra, if the collective observers’ memory is reset prior to a cataclysmic event, such as a species ending asteroid impact, the state of the universe becomes "undetermined."  As a result, it has an equal likelihood of following any of the many subsequent paths, most of which should have nothing to do with an asteroid impact.  And so, by selectively forgetting our past, we can avoid certain doom by starting with a clean slate of future outcomes.  See this New Scientist article.

There is something unsettling about the logic, but his paper seems to be on firm footing: http://arxiv.org/abs/0902.3825.  And the implications are fascinating.  Not happy with how last year's Superbowl turned out?  Keep a single copy of the event, erase everyone's memory, replace all archived bits of history relating to the game, and then we can all sit back and watch the recording again.  Mitra says if we do that, there's a good chance Arizona will win.  Watching the same tape!  Well, maybe not the same tape.  Because once the universe became undetermined again, the physical tape could have encoded any number of outcomes.

This is vaguely reminiscent of "Last Thursdayism," which is one of the possible aspects of Programmed Reality.  Once the universe is reset from an observational standpoint, we would never know the difference and an entirely different future course of events is possible.  If you make the restart point somewhere in our current past, then the recent past can be changed too.  Programmed Reality explains it all!
