Not in my corner of R&D

As long as the spin isn’t the state in superposition A superposition is described by a wave function, but requires that the particle be in two states. If it’s in a single state, it’s still described by a wave function.

The nature of things is metaphysics, not science. What does antigravity have to do with Yahweh?
-
It’s called science. You should become acquainted with it.
-
Fine. Provide evidence and your model to support your assertion.

Does warped spacetime unbend when a mass is removed?

When the wavelength is bigger, QM applies.
-
Again, bollocks. Science is inductive. You can accumulate evidence to support a model, but you cant do a deductive proof. That’s math, not physics.
-
The paths in the integral aren’t real
-
Which is bigger: the wavelength or the singularity?
-
As I just explained, that’s not valid. You’re on the wrong side of the inequality. The singularity has size zero. You can ignore QM for something smaller. Obviously, there’s a problem here
-
Bollocks. There is no “proven” (much less prooven), there is evidence. You are artificially narrowing what evidence you will accept. That’s inconsistent with intellectual honesty
-
You’ve said a lot of things. You’ve not established that any of them are true. It was one of the motivations for going from hot thermal beam cesium frequency standards to cold-atom systems like atomic fountains*. The reduction in the speed of the atoms (which are put in a superposition) reduces the frequency errors introduced by time dilation - since atoms move at different speeds - giving better accuracy and/or stability of the clocks. All consistent with relativity. *a kind of clock I have built. It’s my job.
-
And what is mu? (Usually we use p). I mean, the value. It’s pretty big, right? But not infinite, so the wavelength is bigger than the singularity GR predicts. We ignore quantum effects when the wavelength is a lot smaller than the scale of interest. IOW, we’re on a scale where QM applies.
-
Really? How small is it?
-
Eratosthenes showed it was round ca 240 BC by measuring its circumference. The Greeks already knew it was spherical https://www.aps.org/publications/apsnews/200606/history.cfm
-
QM came a few decades afterwards. Since you don’t do math, what kind of predictions can you make? But no, superposition does not change how time dilation works.
-
You answered your own question.

More like 10 nanoseconds, and it would depend on the mountain. Someone I know did this experiment on Mt Rainier in Washington state http://leapsecond.com/great2005/ "Clocks that run fast gain time, so given our high elevation and how long we stayed, the prediction was that these clocks would gain about 22 nanoseconds. This, not because the clocks were moving (they were in a parked minivan), but simply because the clocks experienced a lower gravitational field by being 5400 feet above sea level for two days." (It's actually gravitational potential that's important. The field strength is one part of that) About a third of a meter, and it took several hours to get statistically significant data, but then this was a few years back. Optical frequency standards today could do it in a shorter time, or measure smaller distances, if anyone was interested in doing such an experiment again. (But it's kind of a stunt at this point, because we know the phenomenon will happen, and who wants to waste the effort of engineering it when you could be doing real physics?) No, that doesn't work as an explanation. It doesn't depend on the kind of clock, and you wouldn't expect a physical mechanism to interact in identical way with atomic clocks made from different elemental species (and there are a bunch that are used). Plus, one of the basic assumptions that makes physics work is that the physics is the same in any inertial reference frame. If that fails, basically all of physics falls apart, and physics works pretty well. Having it be the result of a force means you have to identify this force, and why it's present at differing amounts in different frames. It leads you there being a preferred frame of reference, and physics doesn't work that way. Time dilation is a direct consequence of c being invariant and finite. The result is that length and time are relative to your own frame of reference.
-
Then if anti-gravity relies on it, you need to establish that it's true. What evidence is there that inertial frames are made of anything? What happens to this substance when you move to an accelerating frame? What experiments can we do to verify this? Other than virtual photons being the intermediary in the electromagnetic interaction, they really don't come into play in timekeeping. You can put a system into a superposition of states with different energies (e.g. the two hyperfine states of Cs) and they oscillate between those two states at the frequency that's associated with the energy difference. The measurements are done with photons that are real, not virtual. I don't know what a "vacant frequency state" is. That's what you need to demonstrate, rather than assert.
-
Just saying it's the observer effect doesn't make it the observer effect. Time dilation follows the predictions of SR. There is no observer effect cited in the derivation of the phenomenon, or application of the theory. It's not even clear you know what the observer effect is. Him "struggling with the problem" lacks any evidence to support it. It's a consequence of c being invariant. There's no further explanation needed. What all does that have to do with superposition?

Theories and Proof - split from Quantum theory of gravity.
swansont replied to QuantumT's topic in Other Sciences
The eliminated one has already been shown to be wrong, if theory does not match experiment. Why would you keep it? True but partly in a trivial sense. Completely wrong models tend to be discarded quite quickly (unless they are posted in speculations, seemingly). There has to be something that supports the idea, even if it’s accidental, as with phlogiston -
Thank you for correcting this in a way that is completely unhelpful in answering the question or clarifying what's going on. Quantum physics says zip about gravity. Quantum physics has proven to be the best model for situations where the scale is small (typically though not exclusively small distances, small masses) Relativity superseded Newtonian physics when it comes to gravity, and GR and QM don't get along when at scales where it matters.

swansont replied to QuantumT's topic in Other Sciences
If evidence supports two different models than you need to do a better experiment that eliminates one of them. "Interpretation" is the wrong word for this.
