Oh snap, time travel discovered!

Time crystals! Uncle Rico and Kip knew what was up!!!

Time crystals!

Pretty cool although the name sounds like something you'd see in Star Trek to get out of a dire situation. "If we angle the deflector dish and reverse the polarity on the time crystals we can return the space time continuum to normal!"

 

[GagHalfrunt]

They already announced this next week.

 

[Crono]

Imagine it like jelly - when you tap it, it repeatedly jiggles.

 

[brianmanahan]

they actually have nothing to do with time travel

their low-energy physical state isn't stable but varies over a repeating time interval

 

[MongGrel]

It is odd how many things are out there, and people want to shut down or regress scientifically.

Some people are still ignorant enough to think molecules do not exist at some level, and vaccines and modern medicine is BS, even on twitter accounts.

The hypocrisy runs deep sometimes.

 

[lupi]

Did they name them fusetalk?

[...are structures that appear to have movement even at their lowest energy state, known as a ground state.]

Usually when a material is in ground state, also known as the zero-point energy of a system, it means movement should theoretically be impossible, because that would require it to expend energy, but Wilczek predicted that this might not actually be the case for time crystals.



[But time ........ And it keep oscillating in its ground state. ]

i did a bit of editing there to simplify the thing. they are crystals that, at zero state, vibrate. because they are affected by time in such a way that it creates movement, which is not true of "normal", also called here "equilibrium", matter.

great, it's got potential as another possible energy harvesting solution (and i'm sure they have many interesting applications), but it's not time travel.

Vents are dangerous!

Does this not have something to do with de Broglie matter waves ?
Or the quantum Zeno effect ?

https://en.wikipedia.org/wiki/Quantum_Zeno_effect

The quantum Zeno effect (also known as the Turing paradox) is a situation in which an unstable particle, if observed continuously[clarification needed], will never decay.[1] One can "freeze" the evolution of the system by measuring it frequently enough in its known initial state. The meaning of the term has since expanded, leading to a more technical definition in which time evolution can be suppressed not only by measurement: the quantum Zeno effect is the suppression of unitary time evolution caused by quantum decoherence in quantum systems provided by a variety of sources: measurement, interactions with the environment, stochastic fields, and so on.[2] As an outgrowth of study of the quantum Zeno effect, it has become clear that applying a series of sufficiently strong and fast pulses with appropriate symmetry can also decouple a system from its decohering environment

 

[DigDog]

all matter and states are constantly observed. there is no correlation between intelligence and observation.

 

[William Gaatjes]

all matter and states are constantly observed. there is no correlation between intelligence and observation.

I do not understand the last sentence. I do not want to turn it into a religious subject.

 

[DigDog]

nothing further from religion.
the issue is mainly that, in quantum physics, hypothesis come from mathematical models and not from observation. the various "schroedinger's cat" statements that "something behaves differently when observed" to a normal person, imply a human observer - they literally say, if i KNOW that i am looking at a particle, then the particle gets embarrassed and behaves differently. the reason why this is not accurate is, a particle is being "observed" at any time, just not by you, and perhaps not even by a sentient being. particles which exhibit different behaviour "when observed" imply a state of observation which is brought about by conscious intelligence. the real meaning of this is, when observed, particles behave in a way which is inconsistent with what we believe is the aftermath of that particle's behaviour when not observed, for example, the light-slit experiment.

if this was not the case, it would mean that the universe is a single-observer entity; it does not exist outside of MY perception.

 

[William Gaatjes]

Ah thank you.

If i understand it correctly, that makes sense to me, that anything is influenced by its surroundings.
Even in a vacuum, a given location anywhere in the universe is not empty thus there is always an influence. An observation so to say.
There is no such thing as a real void just our lack of expertise to determine it.
All in due time.
