New theory suggests time is an illusion created by quantum entanglement
New theory suggests time is an illusion created by quantum entanglement
A new definition of time suggests that what we once thought was a fundamental element of reality is actually just a byproduct.
Lunch time doubly so

“I never could get the hang of Thursdays.”
And weekend stasis.
time being purely a consequence of entanglement. It states that the only reason that an object appears to change over time is because it is entangled with a clock.
Wtf. Which clock is this?
One of those cat clocks with the eyes that go back and forth.
Yeah. I read that multiple times and still have no idea what he’s talking about but it’s the most important part of the article
Perhaps it is just a very dry physics joke
The one in my basement. It's a bit dusty. Should I turn it off?
Hold on, let me find a moment of happiness first.
Noooo!!!!
And how did time pass before the invention of the clock?
I wonder if he's talking about a some kind of "clock circuit?"
The clock I keep on my bedside table. It's always watching you.
thank you, I hoped this would be here.
As is birth. Both sides of the dichotomy are dropped in Buddhism. Focusing on death is letting go with one hand, and clinging with the other.
Summary: time is entangled with a clock and appears static from the outside. Why, the article doesnt explain.
If we break the illusion will it fast forward me out of existence?
Yeah you got to be real careful you don't zero sum yourself, much better to chim if you can
Unexpected truestl
Sweet, sweet release.
I thought it was widely agreed that time was a construct?
It has been a common belief in philosophical circles for centuries, but not among physicists. Both Newton and Einstein thought of time as being one of the fundamental properties of the physical universe.
However, in the past decade or two, some theoretical physicists have now come back around to the idea that space and time could instead be emergent properties of a deeper, underlying reality.
If you really want to go cross-eyed, read up on the holographic principle.
My favorite theory is that time and space are reversed in a black hole which could be at the beginning and the end of the universe.
In relativity time is a real dimension like space , but of a different type, and your speed in time depends on your speed in space and on your proximity to big masses, like planets. This kind of physics is necessary to keep the satellites synchronised otherwise their clocks go at a different speed from those on earth, so this is all very real and confirmed.
Time is, change isn't. Time is how we measure change.
"What the hell, Jenson?!? This is our firms biggest case in 20 years and you show up two hours late?!?"
"Oh, haven't you heard?"
next up: coordinate systems don't exist
Lol, well, seeing as time or change is a dimension and direction, like any other, tthat's like saying width or height is an illusion.
I would be careful of confusing "reality" (whatever that is) with our model of reality. Relativity, which treats time as a dimension, is a good model that fits well with most of our observations. It's not perfect, though, and it doesn't fit well with some other observations. That's how we know that it doesn't fully match reality, and why we're looking for a new model.
Paraphrasing the old saying: all models of the universe are wrong, but some are useful.
What effect does the distinction between that and "the best way we have for our minds to think about it" have on it?
Also, unless i remember it wrong, I thought it was relativity that showed the flaws explanation quantum physics' had for time and not the other way round. I mean, I might be but that's my understanding of it right now.
Width doesn't change based on the warping of space
It absolutely does depend on your reference frame. I remember one of my physics 3 test problems was a ship in it's own reference frame was a standard 3 4 5 right triangle. We had to calculate what the observed lengths and angles from a reference frame where it was moving at .96c.
I would suggest, instead, that "Classical Physics" is created by entanglement:
the non-quantum reality at our scale is just what happens, when everything is entangled, to the point of clogging-up-the-works of quantumness, as it were..
.: you get things like .. as you scale up from quantum-level .. the everything-is-discontinuous/everything-is-turbulence .. turns into, once enough entanglement is happening, "laminar flow" in fluid-dynamics, even-though NOTHING in QM is laminar-flow, so there's simply no basis for "laminar flow" at the lower-level...
I wonder how significant this is, really..

Can't even read it.
We present an implementation of a recently proposed procedure for defining time, based on the description of the evolving system and its clock as noninteracting, entangled systems, according to the Page and Wootters approach. We study how the quantum dynamics transforms into a classical-like behavior when conditions related to macroscopicity are met by the clock alone, or by both the clock and the evolving system. In the description of this emerging behavior finds its place the classical notion of time, as well as that of phase-space and trajectories on it. This allows us to analyze and discuss the relations that must hold between quantities that characterize the system and clock separately, in order for the resulting overall picture to be that of a physical dynamics as we mean it.
"evolving system and its clock as noninteracting, entangled systems"
Interesting. Is this related to https://en.wikipedia.org/wiki/Eternalism_(philosophy_of_time) ? (Block Time)
Bare with me here because I am not an expert. I think what they're getting is the same as how gravity doesn't exist. Vsauce did a great video on that, but the general notion is that because space time is curved, objects traveling in streight lines will appear to be drawn closer to one another. "Gravity" isn't fundamental, warping spacetime is. Nothing changed but our understanding of it, which does matter for some more complicated areas.
I think this is similar. Just like gravity "doesn't exisit", it's just an emergent phenomenon: they're saying so is time. They're saying time isn't fundemental, except that it's an expected phenomenon that would arise from other factors, those factors being proposed to be some entanglement crap I have zero ability to talk about.
And I'm putting some words in their mouth with "time isn't fundemental". What they're really doing is proposing a new definition that better fits observed phenomenon/models.
And still, none of this explains why we still have daylights savings time.
