The real answer then has to be that distant material loses its ability to affect material that's beyond detectable range due to the rate of expansion between them being too high to pass signals.
They don't describe it, but that doesn't mean it isn't meaningful in them.
In a correct theory, there must be an answer to that question which is compatible with that theory.
Any theory that says we are and which makes our clocks tick infinitely slower than some other clock is plain wrong.
A valid theory has to be able to run time and advance events if it's to have real causation acting in it.
Time dilation is a geometry thing, not a cause-effect thing. Gravity doesn’t travel, nor does it operate by ‘signals’. I’ve said this before.
QuoteAny theory that says we are and which makes our clocks tick infinitely slower than some other clock is plain wrong.Interesting assertion, essentially declaring only your theory to be wrong.
GR has clocks ticking infinitely faster coordinate rates than others, but they’re just coordinate rates, abstract concepts changed effortlessly with a flick of a pencil.
Your theory demands that one of these coordinate rates is a physical rate, meaning such infinite rate differences are physical ratios, not just relative only to certain abstract coordinate system and not others. I don’t find this entirely contradictory in itself, but you seem to declare it so here. You seem determined to create rules that sink only your own ship.
QuoteA valid theory has to be able to run time and advance events if it's to have real causation acting in it.Your inability to drop that premise makes it a bias.
...you are not making any headway with this example you seem to think disproves STR or something. The argument was that something wasn’t symmetrical, but it wasn’t clear what symmetry you think should be there or how STR (or any theory) concludes that the symmetry to which you refer should occur in your scenario.
The asymmetry of probability was merely introduced as a demonstration that there are asymmetries.
(the most recent of which even set out an experiment that could be carried out to measure absolute speed in expanding space)
You apparently mean something else by this claim of asymmetry, but you’ve failed to spell it out despite repeated requests. Still waiting.
Your experiment would not produce the behavior you suggest. Instead, the two objects would accelerate away from each other due to tidal forces from nearby stars and other masses.
I love how you propose these experiments, safe in the knowledge that they cannot practically be done, and then declare what result will occur despite the lack of actually working out what any theory (LET or relativity) predicts.
Expansion is not a force and does not make object begin to move apart if they’re not already moving apart, and thus cannot play any role in the motion of two relatively stationary objects placed in otherwise empty space.
How does this statement not contradict gravitational waves detected and the speed attributed to them and the energy they transfer ?
Quote from: gem on 13/03/2021 00:30:45How does this statement not contradict gravitational waves detected and the speed attributed to them and the energy they transfer ?Gravitational waves are not gravitational fields. The relationship between the two is like the relationship between electromagnetic waves and electromagnetic fields.
Then surely the waves that are generated that make up the field, transfer energy and momentum ?
and its the difference in this energy and momentum is what is detected by experiments such as LIGO therefore a transfer.
LIGO detects the physical distortion to spacetime, and does not directly measure energy, force, or momentum.
unless things like thunderstorms and distance trains distort space-time ?
Quote from: gem on 13/03/2021 23:14:28unless things like thunderstorms and distance trains distort space-time ?The problem is that the mechanism by which LIGO detects distortions in space caused by a passing gravitational wave is subject to detecting vibrations as well. Trains and thunder produce vibrations.
So is it not just an energy wave detector, detecting an effect from a cause ?
In a perfectly circular orbit it is the direction that is changing and not the speed. Increasing velocity causes time dilation. In SR this would involve a straight line path and a change in speed. That is, acceleration. If the straight line path does not change speed this is inertial motion. The question becomes, does the change in direction alone make the straight line path different in its time dilation than the orbital path, if the speeds are the same. The speed of the orbit is the magnitude of an orbital an angular velocity.
