Lead researcher Dr Gordey Lesovik said by putting scattered electrons back into their original shape they had effectively created a state which went against the ‘direction of time’
Breaking: Scientists Have Reversed Time with a Quantum Computer
Scientists have reversed the direction of time with a quantum computer. The breakthrough study seems to contradict basic laws of physics and could alter our understanding of the processes governing the universe. In a development that also represents a major advance in our understanding of quantum computers, by using electrons and the strange world of quantum mechanics, researchers were able to turn back time in an experiment that is the equivalent of causing a broken rack of pool balls to go back into place.
Here’s a link to the published paper.
This does show “time travel” in an extremely limited way. One of the keys to time travel is defying the 2nd law of thermodynamics and time reversing entropy and a cracked egg can move in a direction towards it’s initial condition which we would say is backwards in time. This distinction is only in our minds because we only experience one direction.
So even if a universe was moving in a backwards direction it would still be moving forward because of entropy. We can be a universe that’s in a timeline that’s in a backwards direction when compared to another universe but these things have no meaning unless both universe exist together as one universe.
This doesn’t mean anyone will be going back in time anytime soon or ever. This could tell us a lot about the nature of reality.
Here’s an illustration of what this means.
Say you have a deck of card fresh out of the pack. This pack is in a low entropy state and it doesn’t take a lot of information to describe the order of the deck. I could say:
The deck of cards is ordered A-K in all Hearts, then Spades, next is Diamonds and finally Clubs.
When I shuffle the deck, now it becomes in a higher state of entropy and it takes more information to describe the order of the deck. This is saying that on a 2 Qubit quantum computer, you’re allowed to move away from the lower entropy initial state to a higher state of entropy but you’re also allowed to move back towards the initial low entropy state. So it would be like shoveling the cards and returning to the initial state when you opened the cards.
So time travel was achieved on a very limited basis. In order to travel back in time, you would have to reverse entropy of the system back towards the initial state. I don’t think that’s possible for classical systems but it happened here. With a 2 Qubit quantum computer they had an 85% success rate and when they added a Qubit more errors occurred and the success rate dropped to 50%.
This result could also point to parallel universes. Let’s go back to the cards example.
Let’s say each shuffle of the deck of cards is like a quantum fluctuation. This fluctuation comes at a cost and it’s paid with dark energy.
So now you’re shuffling the cards but the probable states the cards can be in become separated by dark energy and they’re now isolated systems (universes). So each isolated system would have a low entropy initial state but it wouldn’t be a global initial state. So the isolated systems (universes) could never return to the global low entropy initial condition or the deck of cards out of the pack because now you have four 13 card isolated systems separated by dark energy or a gaziilion universes separated by dark energy but each universe is part of this initial whole. There was an article about this.
Aliens May Well Exist in a Parallel Universe, New Studies Find
According to a new pair of studies in the journal Monthly Notices of the Royal Astronomical Society, there’s a decent chance that life-fostering planets could exist in a parallel universe — even if that universe were being torn apart by dark energy.
In the new study, researchers ran a massive computer simulation to build new universes under various starting conditions. They found that the conditions for life might be a little broader than previously thought — especially when it comes to the mysterious pull of dark energy.
Across several experiments, an international team of researchers from England, Australia and the Netherlands used a program called Evolution and Assembly of Galaxies and their Environmentsto simulate the birth, life and eventual death of various hypothetical universes. In each simulation, the researchers adjusted the amount of dark energy present in that universe, ranging from none to several hundred times the amount in our own universe.
The good news: Even in universes with 300 times as much dark energy as ours, life found a way.
“Our simulations showed that the accelerated expansion driven by dark energy has hardly any impact on the birth of stars, and hence places for life to arise,” study co-author Pascal Elahi, a research fellow at the University of Western Australia, said in a statement. “Even increasing dark energy many hundreds of times might not be enough to make a dead universe.”
That’s good news for fans of extraterrestrial life and the multiverse theory. But a bigger question remains: If galaxies could still thrive on so much dark energy, why did our universe get handed such a seemingly small amount?
Simple answer, FINE TUNING but that’s another thread.
So the question becomes, what could have been the initial global low entropy state?
I would say a very likely candidate is a Highest dimension that would be like a Heaven so to speak.
Say there’s 12 dimensions, this would mean each lower dimension is a holographic projection of the Highest dimension. This dimension would be eternal and like I said a Heaven so to speak. Here’s an article on this that was in Scientific American.
Is the big bang, and all that came from it, a holographic mirage from another dimension?
The universe appears to us to exist in three dimensions of space and one of time—a geometry that we will refer to as the “three-dimensional universe.” In our scenario, this three dimensional universe is merely the shadow of a world with four spatial dimensions.
Speciﬁcally, our entire universe came into being during a stellar implosion in this suprauniverse, an implosion that created a three-dimensional shell around a four-dimensional black hole. Our universe is that shell.
So our universe would be the shadow of a higher dimension so of course if there’s an end to how many dimensions are out there then the 11th or 12th or 5th dimension would be the highest dimension if that’s where the dimensional limit ends. There could also be an infinity of higher dimensions and that would be another story.
They also showed that time reversal undergoes a sort of compression effect or “squeeze” as described by the paper. I wonder if this effect can be scaled up to see what the effects of artificial compression of time before inducing a reversal will do to space itself. As we know, space and time is really spacetime. If we can compress time as a singular effect it may also be possible to create a localized compression of space. If this sounds familiar it is because you’ve heard it before:
As Scott Aaronson, director of the Quantum Information Center at the University of Texas at Austin, says, “If you’re simulating a time-reversible process on your computer, then you can ‘reverse the direction of time’ by simply reversing the direction of your simulation. From a quick look at the paper, I confess that I didn’t understand how this becomes more profound if the simulation is being done on IBM’s quantum computer.”
