I've pointed this out many times as evidence that the duration of the second is the most inconstant time interval in the universe. It makes no difference whereabouts in the universe this clock is placed because the caesium atom will still swing between states the same number of times per second. So accurate is such a clock that if two were to be placed even 1cm apart it would be impossible to synchronise them because gravity would affect them differently. Two such clocks would show that time passes more quickly on the carpet than it does on the bare floorboards beside it. However this clock is a sundial compared with Superman's clock, which can distinguish time intervals on the Planck scale. Such a clock would show that time passes at a different speed for every sub-atomic particle in the atom because they all have different masses and they all move at different relativistic speeds. It is this inescapable fact drawn from GR which gives rise to the strong and weak nuclear forces and electro-magnetism. This is the elephant in the room of physics, the truth hidden in plain sight. THIS IS QUANTUM GRAVITY. THIS IS THE GUT. THIS IS THE THEORY OF EVERYTHING.

What do you think that means in practical terms? What is 'energy' that it can turn into 'matter'?
I think to say that energy "turns into" matter is a conceptually flawed way to think of this. I prefer to say that energy "encodes for" matter or that matter is an emergent form of energy. Emergent entities are only definable by their physical properties and are thus solely observer constructs. To think of matter as objectively real bits of "stuff" is completely wrong-headed. Imagine an alien civilisation in a far-flung galaxy which evolves to the same technological level as we have. Do you seriously reckon they'll have invented the same matter particles as we have to model the world around them? The odds of this happening twice, even in a universe this huge, is infinitesimal because there are probably an infinite number of possible ways in which we could model the sub-atomic world, all of which would require different mathematical tools but all of which would work and yield testable predictions. I accept that there is such a thing as an objective reality but I do NOT accept that this reality can be modelled other than subjectively. In the final analysis physics is an exclusively subjective narrative.

Well, 'massless energy' is essentially an 'excitation' moving through a Quantum Field, according to the theory. It's 'mass' depends on how it interacts with the Higgs Field, again; according to the theory.
I have no interest in aether theories because no evidence exists to support the aether. To suggest that energy behaves in accordance with the dictates of a field is an action-at-a-distance hypothesis so this ontology of fields is utterly bogus in the absence of an aether because it places effects before their causes. Matter and energy behave according to the dictates of gravity and for no other reason. It is this behaviour which the observer models as a "field" but the field itself does not exist. Physicists can invent as many particles, fields and forces as they choose to describe their observations because their paradigm of model-dependent realism is simply "physics is what works". Don't make the mistake of equating the map with the territory. All this quantum field bullshit is completely unnecessary in a spaceless model, which means that all the mind-numbing mathematics which was invented to model these non-existent fields was a spectacular waste of intellectual energy hauntingly reminiscent of Ptolemy's epicycles.

Why should sub-atomic (do you mean fundamental?) particles be changing their form?
To suggest that sub-atomic particles are fundamental entities is absurd because they each have different physical properties and they each move slower than c. Clearly these properties are being encoded for at the Planck scale, which is 20 orders of magnitude smaller. The string theorists were barking up the wrong tree altogether but I'll give credit where it's due all the same. They knew bloody well that the particles of the Standard Model were NOT fundamental.
uwot wrote:If they change their form, they are no longer the specific set of characteristics that identifies a particular particle, but yes: any energy that transforms a particle can travel at a maximum of c.
This is more like it because it gets closer to the confusing notion of the so-called "quantum uncertainty". Think of a particle as literally changing into a different particle at the speed of light and you'll get an idea of what's happening at the Planck scale. The particle has emergent properties which the energy which encodes for it doesn't have, a fact which Newtonian physics cannot accommodate. Then think of the particle in its emergent form doing all manner of different things as a result of these changes and you'll get an idea of how an atom is encoded for. The atom then has properties which its sub-atomic constituents doesn't have and can thus encode for molecules, etc. This is a model of a non-Newtonian world because it is entirely self-organising, completely deterministic and utterly beyond prediction. This should be a very familiar model to anybody with a reasonable knowledge of physics because galaxies operate in exactly the same way and all the hierarchical levels of reality from the Planck scale to the cosmological scale are thus nested within each other like matryoshka dolls. Such a non-linear dynamic system is exquisitely modelled in the Mandelbrot set.

This means that the speed of light and the speed at which time passes are one and the same thing.
How does that follow?
The speed of time is determined by gravity and the speed of light is determined by the speed of time. Obviously light cannot travel faster than time, which was the point of my gravitational lensing thought experiment. Think of reality as a computation and think of the speed of light as the processing speed of this computation.

Writing a story that is consistent with the observed data is easy compared to coming up with something that makes predictions for observations we are not yet aware of.
A very good point, and one which I am acutely aware of. However my philosophy doubles as a legitimate scientific hypothesis because it yields a testable prediction which, if validated, would unambiguously falsify current theory. It took me a lot of years to find such a prediction but as often happens in such predicaments it was actually sticking out like dog's balls all along. Think about what entanglement is if space is merely an observer effect. Unfortunately there'll be no Nobel for me in this because this is not physics and there is no category for philosophy.

uwot wrote:Well there is conclusive evidence that there is no absolute aether that we are moving relative to, which has been known since Michelson-Morley. The Higgs field has been equated with 'the aether' and according to Quantum Field theories, QED and QCD, particles are excitations of 'fields'. The term field can be confusing, because it can be used to mean 'field of influence', as in the area where particular behaviour can be observed. That is similar to what you say about the 'logical positivist' basis of physics or instrumentalism/shut up and calculate. By identifying 'fields' with substances, you allow them 'physical' properties and elimininate 'spooky action at a distance'. It's only a hunch, but I think the most plausible explanation of all the phenomena that give the impression that the universe is made of something, is something the universe is actually made of.
Our positions are much closer than might appear at first blush. However you seem to be ignoring the role of the observer in defining the observation. In the final analysis reality is simply self-organised information which we are left to make sense of.
"The most incomprehensible thing about the universe is the fact that it is comprehensible"...Albert Einstein.
Albert didn't understand the role of the observer either, but Kant bloody did.
