Access to the past would open all sorts of new possibilities of more than travel.
By Charles Q. Choi, ISNS Contributor via Inside Science
(ISNS) — Time travel is often a way to change history in science fiction such as “Back to the Future” and “Looper.” Now researchers suggest a certain kind of time machine could also possess another powerful capability — cloning perfect copies of anything.
However, scientists noted the way these findings violate what is currently known about quantum physics might instead mean such time machines are not possible.
We are all time travelers in that we all move forward in time. However, scientists have suggested it might be possible to move back in time by manipulating the fabric of space and time in our cosmos. All mass distorts space-time, causing the experience of gravity, a bit like how a ball sitting on a rubber sheet would make nearby balls on the sheet roll toward it. Physicists have proposed time machines that could bend the fabric of space and time so much that timelines actually turn back on themselves, forming loops technically known as “closed timelike curves.”
These space-time warps can develop because of wormholes — tunnels that can in theory allow travel anywhere in space and time, or even into another universe. Wormholes are allowed by Einstein’s general theory of relativity, although whether they are practically possible is another matter.
A key limitation of this kind of time machine would be that any traveler using it cannot go back to a time before the device was built. It only permits travel from the future back to any point in time after the machine was constructed.
Scientists have for decades explored what closed timelike curves are capable of if they are possible.
One complication they would encounter is the no-cloning theorem in quantum physics, which basically forbids the creation of identical copies of any particle one does not know everything about to begin with.
In classical physics, one can generate a perfect copy of anything by finding out every detail about it and arranging the same components in the same order. However, in the bizarre world of quantum physics — the best description so far of how reality behaves on its most fundamental levels — one cannot perfectly measure every detail of an object at once. This is related to Heisenberg’s uncertainty principle, which notes that one can perfectly measure either the position or the momentum of a particle, but not both with unlimited accuracy.
Nearly 25 years ago, theoretical physicist David Deutsch at the University of Oxford in England suggested closed timelike curves might actually violate the no-cloning theorem, allowing perfect copies to be constructed of anything. Now scientists reveal this might be true in findings detailed in the Nov. 8 issue of the journal Physical Review Letters.
To understand this research, imagine one builds a time machine in the year 2000. One could place a letter into the device in the year 3000 and pick it up within this box in 2000 or any year between then and 3000. From the perspective of the letter, it goes inside this time machine into one mouth of a wormhole in the future and comes out the other mouth of the wormhole in the past.
However, theoretical physicist Mark Wilde at Louisiana State University, in Baton Rouge, and his colleagues found this scenario may be more complex than previously thought. Instead of the time machine containing just one wormhole, it could possess many wormholes, each at some point in time between the future and the moment of its creation. A letter entering the box in 3000 might exit from a wormhole in 2999, instantaneously go back into that wormhole and emerge in 2998, and so on.
“It’s like there are 1,000 different particles emerging from all the wormholes, but in fact they’re all the same particle you sent in the beginning,” Wilde said. “You just have all these temporary copies emerging from and going back into these wormholes.”
The Secret teaches that victims are always to blame, and that anyone can have anything simply by wishing.
Prepare to have everything you’ve ever wanted, simply by thinking happy thoughts about it; and be careful of negative scary thoughts which might cause those things to happen to you to too. Little did you know that, just like in the original Star Trek episode Shore Leave, whatever you think of — either good or bad — will actually happen! This is the premise of Rhonda Byrne‘s 2006 book and movie, both titled The Secret.
Rhonda Byrne is an Australian television producer and author. Her book and movie propose that many of the most successful people throughout history have known a “secret” — a secret closely guarded in the marketing materials for the book and movie. The “secret” turns out to be nothing more than the old motivational speaker’s standby, that positive thinking leads to positive results. But she took the idea a step further. The Secret claims that you can actually cause events to happen by wishing for them hard enough, literally like winning the lottery or recovering from terminal illness. Similarly, a focus on fears or negative ideas will cause those things to appear or happen as well. The Secret calls this the “Law of Attraction”. The Secret further makes the completely unfounded claim that many great people knew and relied upon this wisdom, and taught it to others as “secret teachers”. “Secret teachers” included Buddha, Aristotle, Plato, Sir Isaac Newton, Martin Luther King Jr., Carl Jung, Henry Ford, Ralph Waldo Emerson, Thomas Edison, Albert Einstein, Winston Churchill, Andrew Carnegie, Joseph Campbell, Alexander Graham Bell, and even Beethoven. This claim is just a made-up lie: Most of these people lived before the “Law of Attraction” was invented, and there’s no evidence that any of them ever heard of it.
As of today (2008), a year and a half after its release, The Secret remains #26 of Amazon’s list of best selling books, better than any Harry Potter book. It has over 2,000 customer reviews. Half of them are 5 star, and a quarter of them are 1 star. This is the sign of a polarizing book. Most people either love it or find it to be utter nonsense. In the case of The Secret, most people love it. Thanks in large part to promotion by Oprah Winfrey, The Secret sold 2 million DVD’s in its first year and 4 million books in its first six months.
Many of the people appearing in the movie version of The Secret are motivational speakers who spout the same old “If you can dream it, you can do it” nonsense that Amway salesmen have been chanting for decades. In essence, part of what Rhonda Byrne has done has been to simply repackage Motivational Speaking 101 inside the wrapper of a century-old philosophical construct, which we’ll look at in closer detail in a moment.
As you’ve probably heard, The Secret has been roundly criticized from all quarters. The most common criticism is of The Secret’s assertion that victims are always to blame for whatever happens to them. Whether it’s a rape victim, a tsunami victim, or a heart attack victim, The Secret teaches that they brought it upon themselves with their own negative thoughts. This idea is, of course, profoundly offensive in many ways. Doctors attack The Secret for teaching that positive thinking is an adequate substitute for medical care in cases of serious illness: Wish for it hard enough, and your cancer tumors will melt away. Religious leaders criticize The Secret for its ethical claims that victims are always to blame, and for promoting the attitude that anyone can be just like a god by wishing hard enough. Many financial critics and advisors have pointed out the dangers of yet another baseless get-rich-quick scheme. The list of critics of The Secret goes on and on, as tends to happen to any mega-successful franchise.
So the question people ask me is “What do I think of The Secret?”

Iran’s technological prowess has reached an all-time high. It claims to have solved the metaphysical conundrums associated with time travel.
Ali Razeghi has not created a flux capacitor, and probably doesn’t own a DeLorean. But the managing director at the delightfully-named Centre for Strategic Inventions claims to have put together a device that fits into a “personal computer case” whose algorithms can discern key details about the next five to eight years of a user’s life based merely on a fingertip impression.
“It will not take you into the future,” Razeghi told the state-run Fars news agency, according to the Daily Telegraph, “it will bring the future to you.” With that, Razeghi becomes the most significant scientist since Albert Einstein.
Taking Razeghi at his word, today marks the day that Iran becomes a global economic and military superpower. It no longer matters how many aircraft carriers or afloat staging bases packed with laser cannons the U.S. idles near Iranian shores. The commandos who operate in secret across the Persian/Arabian Gulf are now irrelevant. Iranian air defenses will now know precisely where and when Israeli jets seeking to bomb Iranian nuclear facilities will enter their airspace.
Iran’s woes at constructing an intercontinental ballistic missile now appear trivial. Nothing matters more than accurate, predictive intelligence for discerning an adversary’s move before he makes it. An Iranian chrononautical effort gives the Islamic Republic a near omniscience: the ability to access, process and utilize data before it even enters existence. It is entirely possible that the implications of Iranian trans-chronal access are already rippling backward in time across the multiverse, transforming reality in ways that are difficult to comprehend.
There are limited countermeasures Iranian adversaries can design or field. One option would be to design son-of-Stuxnet malware to attack the device itself. But there is great likelihood Razeghi’s machine will have already warned the Iranian security apparatus of a forthcoming cyberattack. A more fruitful option might be to out-invent Iran, and create a better forecasting device than the Iranians possess. Such a move carries heavy implications for the fabric of reality, but Razeghi has already crossed a Rubicon, and U.S. policymakers must now ask themselves how long they are prepared to tolerate an Iranian monopoly on time travel.

A white Ford pickup pulled up to cattle pasture near Ponca City, Oklahoma, in early Fall 1971, and stopped at a gate. Karl, Mark, and Gordon worked for cattle feed distributor and were sent to this remote area to pick up a feeder. What they found there has kept them silent for 41 years.
“We opened the gate, which was barbed wire with no lock, and entered,” Karl said. “We went on the property, which was covered with grass up to and over the hood of the truck.”
They drove through the tall grass to the tank that sat close to a red barn and got out of the truck.
“We realized the tank was almost half full and too heavy to load,” Karl said. “We decided to leave and drove around the red barn and we saw a large, two story white house, with no lights in front of us.”
The trio drove back to the cattle feed company and the boss said he’d drain the tank and they could pick it up tomorrow.
“We went to the location to retrieve the tank the next night,” Karl said. “This time we decided to go through the old white big house on the hill and brought our shotguns.”
They drove onto the property over the path they’d made through the grass the day before and loaded the tank. Then they pulled around the barn toward the house. What they saw burned into their memories.
“It was no longer there,” Karl said. “We walked up the hill where it stood and there were no signs of demolition, no foundation, nothing at all. What we all seemed to witness the night before was no longer there. We have talked to each other over the years but none of us can begin to explain this vision.”
Did these men witness a slip in time?
Time slips have been reported throughout history. English women vacationing in France in 1901 claimed they stepped into the French Revolution, and two English couples traveling in Spain in the 1970s stayed at an oddly archaic hotel that was simply gone on their return journey.
Physicists like Albert Einstein, Michio Kaku and Stephen Hawking have all said time travel is theoretically possible; our science just can’t achieve it. But what if nature can?
