Total ignorant newb question, but the inconsistency the article talks about in measuring time in quantum systems, if that gap were related to the lack of gravitational effects at the quantum scale, and quantum weirdness is precisely about simultenaeity and problems with reconciling states with time measurements, is it because gravity and time are really just effectively the same thing?
Logically, both time and gravity are essentially inferred substrates to how we observe space and mass/energy.
Regarding the explanation in the article about how they're using thermodynamic entropy and information entropy together as a defining gauge for clocks at all scales, I would wonder if time relates to mass and gravity the way width relates to height, in that one is conceptually "perpendicular" to the other, and what it might mean for time to be perpendicular to gravity (if they weren't just the same thing).
Last I read, there wasn't a full quantum theory of gravity that is consistent with experimental observations of macro gravity via relativity because of quantum "weirdness," because at that quantum scale there is almost no physical "time" effect other than entropy that we use as a reference.
What we call quantum weirdness could literally just be the lack of time effects preventing things from happening all at once, and it's absent because gravity at that scale is effectively absent.
No gravity, no time (quantum weirdness). Less gravity from being far from a well, faster time (aging effects). Total singluarity gravity, stretched time over its horizon (black hole time). When you never see them together, I'm just saying it starts to looks suspicious.
I only mention it because I was literally just on a crazy bit that started with the joke where someone said, "faster than light travel is impossible," and ever the optimist I said, "helicopters, also impossible," which is funny to anyone who knows about helicopters. It turned into whether instead of super massive objects distorting space, there could be lower energy pulses and oscillations with effects like a resonant frequency, where instead of causing big distortions, could cause whorls and ripples of equivalent "space-turbulence" around them - not unlike the conceptual effect of helicopter blades, but using EM, and likely from an element or crystaline structure that facilitated an amplification feedback loop. You could detect the distortions because they would become "cold," as the space around them "spread." If gravity and time were the same thing, you could create a wave in space using turbulence and travel the substrate (time/gravity) directly. Faster than light travel is impossible only in space, where in a time/gravity substrate it's moot.
Totally sci-fi speculation, but as a result I have since put a sticker on my eurorack synth that says, "danger: time machine"
But seriously, how much confidence do we have that time and gravity are NOT the same thing?
- bryan0 5y ago> is it because gravity and time are really just effectively the same thing? Well gravity is the curvature of spacetime. So maybe not time exactly. It seemed like the question that needed to be answered was does the inherit randomness of a clock tell us anything about spacetime itself? Or is it just telling use how well we can measure it?
