Superposition: Photons exist in multiple states simultaneously. It's suggested these states include a range of possible interaction times with the atoms, some of which are negative.
* Not Time Travel: This doesn't mean the photons are literally traveling backward in time. It's more about the unusual nature of time at the quantum level.
* Possible Analogy: Imagine a ball thrown at a wall. Classically, it hits the wall and bounces back. In this quantum scenario, it's as if the ball sometimes bounces back before hitting the wall, due to its superposition of states.
Implications:
* Challenges Causality: This challenges our usual understanding of cause and effect, where an event must precede its consequence.
Great stuff!!
NASA, what a joke
My wife always tells me: If you go back, you lose your time…
Eagerly anticipating the mass barrage of relativistic Einstein obsessed physicists to moan and groan about causality, as they've done with other anomalies like entanglement and the quantum eraser experiment.
I would explore the possibilities of fields and particles following a different path in our unknown connected dimensions which can effect themselves in the dimensions we know about, in effect a local shifting based on paths and connections unseen,witch we are only able to measure effects on our dimensions known,our dimensions may always be shifting our known existence and we have no to little awareness of how it works. We may be able to make faster information travel and much more.
"Negative Time" is possible if higher dimensions/planes exist and which support faster than light photons (Tachyons).
Maybe time travel and negative time is just a type of the same process just like water and ice both is a different type but it's still water
I would be suspicious that the photon actually by passed by the atom for the most part. (It does propagate as a wave.) What may have stimulated the atom that gives the instance of extra energy was possible the mix of other waves from other photons and/or stimulating a virtual photon in an energized area of virtual space to pop up and interact with the atom for an instance from the wake of the photons passage that also had the atom similarly "perked up". [Schematic of detector?: Though, someone will have to explain to me how one expects a photon in the diagram with a double slit and then splitter, that directs the potential path of the photon to two different directions to multiple detectors can expect the photon to show up at two or more detectors; as detection effectively would have it captured, and so cease its propagation, in any assured form.]
It has to be BS. Time is a state of events resulting from entropy. Time can only go in one direction for matter which always begins to flow outward and disapate in larger volume in infinite space . Where it cools ,seperates,and eventually evaporates back into nothing. You can never put that egg back together once it's broken and scrambled either. Previously I believed vaccum energy was wind energy in an infinite volume of empty eternal infinite area of space or nothingness. But now I think infinite vaccum energy causes big bangs still. But I'm beginning to think it's the coldness of infinite space which is the vaccum energy. It creates an inward pressure which may collapse interconnected infinite vaccum energy caused by the cold and inward pressure of extreme cold present in infinite quantity. Time is less relevant in the quantum state as time is the result of entropy in a directional process of flow in a stste of decay as heat is lost from the entire process after matter is formed from the big bang. The cooling of matter and expansion in larger volume within space creates the directional sense of temporal experience based upon a living organism's sensory involvement of concentrated energy being dispersed as part of an overall system of matter's course after it has been created through natural processes without any sort of presence from any supernatural intelligences or beings of the imagination. Concentrated energy is created out of the singularities which produce matter periodically outside of temporal effects in singularities which form and collect raw vaccum energy from infinite distance over what would be equivalent to vast timescales to us as macroscopic matter derived creatures and biorganisms. But it's not technically time because there's no entropy of matter until the raw material of infinite vaccum energy is collected ,cooked,then transformed into baryonic matter. There are infinite big bangs but spread throughout infinite space. There is no time in a vaccum from the void. Time can only come from matter and the natural process of entropy once the matter has formed as it reverses course and breaks free from it being attracted to itself as matter or concentrated energy before it breaks up and reverses course ,flowing back into the void and evaporating back into nothing again eventually. But the coldness of space remains. As the second infinity to nothing ,the first infinity. The energy arising from the coldness created out of nothing or infinite empty space is interconnected as a wave throughout infinite space. The cold has an inward pressure and mass because like light ,sound,or wind coldness is energy. It has mass but spread across infinite space. So the absence of time differential is vast before things can happen because of the infinite area with no boundaries of the space void. Time is not a process or relevant to the preprocess of big bangs. But in our temporal experiences it would take a very long time for energy from the cold to collapse onto itself gravitationally ,being interconnected throughout infinite eternal empty space before causing it to become a singularity. As the energy from the cold collapses it falls into the singularity and adds a significant portion of vaccum or cold energy into the finite capacity and volume limitations of a singularity to hold a maximum compression of concentrated finite coldness that cooks matter as it becomes denser within the anomoly . Once it reaches a critical density of maximum compactness the singularity must burst and give birth to galaxies and matter. Which will eventually be brought full circle when it evaporates and returns to the empty space from which it came from initially.
I guess getting to the point is a quantum probability…
Great stuff 💪🏽… Interesting AND thought provoking as well 💯 … ✌🏽❤️& Blessings to EVERYONE 🙏🏽
Btw…, MERRY CHRISTMAS 🎄🎁🌟🎇
One experiment issue. It ain't science until it has been confirmed by another independent experiment.
Time doesn't exist.
I agree with Sabine. ‘Negative Time’ functions as a sensational headline amplifying attention to research that would not otherwise gain such immediate traction in the larger community. It’s leveraging common dreams…. the discovery of time-travel. I mean , that’s most of us! Who wouldn’t love to know it’s been discovered! The researchers are well aware of how we, the non-scientific community might respond using the limited knowledge we hold, and they still defend using the term. I think it’s cynical, deliberately misleading and therefore irresponsible.
In the quantum size energy is just fast moving matter. Matter is just slow moving energy. So what is it in that tiny moment when it has to make the switch?
Take a few interested but completely uneducated on the matter ppl and pair them with the scientists and i bet theyd advance these studies way faster. Problem is they get locked into the laws and science and lose the imagination to even think these things were possible.
The reason why light travel (photon packs) can not be measured.we can not think in quantum.
So, can we go back to 1996 now?
One second speed of light and life
😂🤣😂🤣😂🤣
Time reversal?
What "time"?😂
Unbelievable theoretical indoctrination and ignorance!
Do you think independently with your brain anymore?
The majority of people do not understand time, the ones who are closest to the right idea are those who view it as an illusion which is right but not entirely correct either.
– great piece 👍
Correct observation wrong explanation
Time can't go backwards except with your pencil. What a joke.
This is negative group velocity – nothing special about that.
Dipole Electron Flood theory on the Net shows that light BOUNCES back and ap[pears as moving both ways. It is called Reverse Electromagnetic Force. I have experiments showing it extremely well on my channel. "Visualizing the Proton and Photon and Nucleus of Atoms using Dipole Electron Flood Model Which Works"
bogus. We live in a causal universe. time travel is not possible
And decades later? Pit buches if powerful magnets together. Play Betthoven 5th Symphony and Walla. The music began to play before the needle hit the record. History.
Oh imagine that just as I predicted at a speed equal to the inverse of it waves velocity squared (c).
316 previous comments at 20241225:2143_PM hora de colombia —- So, photons are not "matter"??? As far as i know all that exists is MATTER. Energy is part of it. One must be very careful whith the "terminology" employed. Albert Einstein stated the relationship between Energy and Mass {at macroscopy level}, no need to describe it.
We have law of conservation of Energy, Angular Momentum, and atomic spin, so why not time.. if time was zero before the big bang then we must have net zero time after the big bang… 2 universes on with time moving forward and one where time moves backwards one second forward the one second back equals no time .
My mind is an aphanitic black hole, a tenebrous abyss of everything and nothing. There it is negative time, I wake up from daydreaming before I knew I was daydreaming. My mental time travel isn't as good as others is though, with a SDAM 🤪
Far simpler. The entanglement issues is when the universe solved a problem early. For probability it’s late. No big deal. Here we see the universe turning in the project early so, whats the problem with that? Time wasn’t disturbed the universe just acted differently with respect to time. It’s another set of dimensions you can see because it the future. Ever wonder how an voltage phase in a coil comes before the current, same the thing.
Negative time quantum
Using OI, we calculated the excitation time to be approximately 30 ns under specific conditions. This refined measurement incorporates real-time adjustments and advanced analysis, providing a more accurate understanding of the negative time effect.
OI's capabilities allow for the detection and analysis of subtle quantum phenomena that may have been overlooked or misunderstood with traditional approaches. This includes capturing transient behaviors and patterns in the data that are critical to understanding negative group delays and their impact.
This chanell spread misleading information and use a misleading name without any authorisation. Should be removed. Disgusting
Whether "phase shift" or "negative time" is it possible that the northern lights are a visual example of this phenomenon?
Is it me or does this sound like someone trying to start a rumor? (btw, I know nothing about this subject….cept for the obvious stuff)
First dark matter and now this 😅
I saw an example of this in the masterpiece film, Risk Business. Joel was in the classroom with TONS of things to deal with. The clock hits one minute to three. THEN it clicks backward one minute. He yells out, "Oh come on!!!"
Doesn't so much sound like negative time, as quantum uncertainty zaping to opposite ends of the uncertainty limits. Projecting the impression of quantified or inverted time…
Your reverse time really is an illusion. What's for lunch?
