FULL TITLE:
QUANTUM TIME Scientists have built world’s first ‘time machine’ in experiment which defies the laws of physics
============================================================
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'
============================================================
SCIENTISTS have built the world’s first time machine — sort of.
Working with electrons in the bizarre realm of quantum mechanics, they first created the equivalent of a break for a game of pool.
The “balls” scattered and, according to the laws of physics, should have appeared to split in a haphazard way.
But researchers managed to make them reform in their original order — looking as if they were turning back time.
Lead researcher Dr Gordey Lesovik, of Moscow’s Laboratory of the Physics of Quantum Information, said: “We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”
His team used a rudimentary quantum computer, which carries information on subatomic particles. He hopes their findings, in journal Scientific Reports, will help improve processing power.
Not quite Dr Who, but even Time Lords had to start somewhere . . .
So how does it work? Well the "time machine" is actually a rudimentary quantum computer made up of electron qubits.
A qubit is a the basic unit of quantum information – a unit that represents one, zero, and both one and zero at the same time.
Researchers ran an "evolution program", which caused the qubits to enter a complicated changing pattern of ones and zeroes.
And during this process, the order was lost – like hitting balls at the start of a game of pool.
A separeate program then modified the state of this quantum computer so that it evolved backwards, returning from chaos to order.
This allowed the qubits to return to their original starting point.
Scientists were able to perform this so-called "time reversal" successfully 85% of the time with two qubits, and had a 50% success rate with three qubits.
Computer chips are getting smaller and faster, but there's a limit to how small we can go Quantum computing is a way to keep making computers faster once we hit the limit of normal computer chips It's based on the idea of using tiny particles that can exist in multiple random "states" at any one time Quantum bits (or qubits) in a quantum computer could be a one, a zero, or both at the same time Think of a giant pole running through the centre of the earth The pole would be in the middle, but also at both ends of the planet, simultaneously In this example, a qubit could be at any point of the planet, and at all points of the planet, at any given time That means a qubit could store huge amounts of information, because it has millions of possible "states" This means that a quantum computer would be able to perform complex tasks very quickly by utilising qubits Sadly, quantum computers are still very much a work-in-progress But scientists hope that by using tiny particles like photons, it would be possible to advance quantum computing research
Doesn't socialism do that already?
No, socialism goes against the direction of sanity and common sense................
Z Ping!...............................
In the meantime, some guy mysteriously showed up in the lab named Gronk and commenced to whipping all their a$$es.
Why would Gronk do that?...............
Interesting. Needs confirmation.
Trump could use that machine to go back in time and pick anybody other than Sessions for AG.
Billiard balls do not scatter in a "haphazard way". They move in an entirely predictably way, IF you could precisely define the exact properties of ALL of the environment. Factors like ball curvatures and three axis stiffnesses at the points of contact, ball spacings, table friction and stiffness, path direction and ball spin, etc. all effect the paths, making the final result appear to be "haphazard". Knowing all of these properties, would make it possible to calculate the paths backward to reestablish the original shape. It would not make TIME go backward, it would just make a calculation of the ball position "go backward".
Speaking of time, is there any way to speed all this up? I'd like to go back and correct a few little blunders.
I wonder if this one needs 1.21 jigawatts...
Yeah, that was my take too. Just reverse the physics and you’ll end up in the same state as you started.
...that said, I could easily be missing the point :)
I get all my scientific information from the Sun-UK.
“We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”
I’m interested in that word “artificially.”
That was a discussion I had with an engineer friend of mine decades ago. I posited to him that there was no such thing as ‘random’. If we knew and could calculate all of the variables, we would be able to determine the outcome of every encounter. Our current state of technology is not there, yet.
If it worked, then it DIDN’T defy all the laws of physics. Obviously it meant that we didn’t get the laws of physics right.
However, this is not time travel. This is not reversing time’s arrows. Cause precedes effect, and effect follows cause. That is not a law of physics - it is a first principle that must be accepted if there is to be any understanding of the world at all.
There is no way for us mortals to step out of the cause-effect continuum.
Your electrons can be sent into the future.
But your protons & neutrons will have to stay behind.
