A mass can be be lifted with force less than its weight
Lol considering I am only 5 foot seven and 155 lbs my legs can press 250 kg for ten reps on a Universal machine. 60 kg is nothing.

What is Space made of?
You would deal with the position and momentum uncertainty with quantum particles however relativity itself is a classical theory which it's mathematics doesn't incorporate probabilities or harmonic oscillators for the uncertainty principle. Those get incorporated when you deal with theories such as QFT. However freefall paths via principle of least action (Langrangian) does involve uncertainty in the chosen path that the particle will take at each infinisimal. (GR itself doesn't get too much into the Langrangian) so when studying GR I wouldn't worry about uncertainty in freefall paths. That's would be far too distracting until you get really comfortable with GR

Welcome back and excellent post as always. I particularly agree with your caveat that spacetime is a mathematical model.

A New Theory of Motion and the Speed of Light
From what I can tell he is rambling. Particularly since he also stated Ie no seperation distance ???? Tell me OP when are you ever going to address direct questions correctly ? Every response you give leads to more confusion. Sounds like you don't know how to describe your theory. Your now invoking virtual phase and group velocity but still haven't shown how your keeping the phase velocity equal to c for all observers... This asked of you by several posters.... Now here is another question for you you specifically stated a wave requires a medium to propogate. So why does both you phase and group velocities have wave equations ? Perhaps you should start with the basics [math]v=\lambda f [/math] [math]k=\frac{2\pi}{\lambda}[/math] [math]f=\frac{2\pi}{\omega}[/math] At least you can start with the basic electromagnetic wave equations. You should at least realize in a vacuum you can have any frequency or wavelength as long as [math]\lambda f=c [/math] Though if you want the modern method use https://en.m.wikipedia.org/wiki/Electromagnetic_wave_equation Though you would have to admit your phase and group velocity usage is completely wrong in modern terminology usage.

A New Theory of Motion and the Speed of Light
I have read your papers and the biggest lack I can see is that you haven't understood that physicists in the early years do not understand basic wave mechanics. You are quite wrong on that aspect. Please define absolute motion including the vector transformation rules required to keep phase velocity equal to c for all observers. Unless you can do that I don't see any validity in your theory. pS mathematics not words. From what I have read your theory requires you definition of phase velocity being equal to c for all observers. So provide the necessary vector transformation rules required under 3d treatment to produce that requirement.

A New Theory of Motion and the Speed of Light
One of the problems ppl have when they present ether based theories is the assumption that the tests have stopped at the more commonly known tests. There have been dozens of different tests looking for an ether that all show null results the latest that I am familiar with was done in 2009. This test looked for Ether at the quantum level with its extreme precision. [math]\Delta c/c=1*10^{-17}[/math] for the precision level. Still absolutely no indication of an ether. @Op your going to need some incredibly strong evidence well beyond any mathematics your papers indicate to account for how these null results can occur with your theory. Quite frankly without extremely accurate precision tests you really don't have much hope in competing with the overwhelming evidence against you. Here is the relevent arxiv to the result above https://arxiv.org/abs/1002.1284

A New Theory of Motion and the Speed of Light
Well I for one have no confidence of validity from what I have read thus far. Too many inaccuracies in the paper in terms of what is involved in stated experiments. Good example being the M$M experiment where the frame dragging aspect of an absolute frame is ignored as one example. From what I can determine non standard use of the terms phase and group velocities. Though quite frankly having an absolute frame using wavefuctions makes absolutely zero sense under vector symmetry treatments. Particularly one being emitted from a moving source. You would still require time dilation and length contraction to keep the phase velocity constant.

A New Theory of Motion and the Speed of Light
I realize that Studiot but quite frankly I am unclear if he truly understands the difference between a phase velocity and a group velocity. So I gave an example. Relativity also does little to define a particle as per wavefunction states. Yet this is important to understand why relativity doesn't deal with phase velocity but the group velocity. Ie an earlier statement the phase velocity does not describe the particle velocity the group velocity does. This relates back to the following question if you think about it. If the OP sets the phase velocity as constant and equal to c then the group velocity must equal the phase velocity to satisfy the equation you posted. In the case of a massive particles who's group velocity is less than c the phase velocity must exceed c. You must apply both the massless and massive case under relativity but the OP clearly doesn't understand why the group velocity is the particle velocity.

A New Theory of Motion and the Speed of Light
Phase velocity varies depending on its wavelength in a dispersive medium. The only time it can be constant is in a vacuum. However group velocity is also constant in a vacuum. If you have a paper showing otherwise please post it (preferably arxiv) I'll bet there is some medium involved in those papers. In essence in circumstances where w does not equal ck. However your still missing one key problem. [math] the group velocity and not the phase velocity describes the velocity of a particle [/b] Good example the QM or QFT superposition particle state is described via its group velocity.
-
A New Theory of Motion and the Speed of Light
I too look forward to seeing how the OP is defining group and phase velocity as none of his descriptives match the mainstream definitions.

I would also suspect an absolute frame would have additional ramifications for GW waves. Even in gravitational lensing there is no indication of a refractive index you would distortions that are not present on observation. Not to mention CMB distortions or lack of.
-
A New Theory of Motion and the Speed of Light
You obviously didn't read or understand a single formula I posted if your still declaring this to be a problem. In a vacuum the group and phase velocity are both constant. A vacuum isn't a dispersive medium. Perhaps you need to understand that first. As mainstream science already does. Not that phase velocity has anything to do with particle velocity. Which is also important to understand. It is the group velocity that is important to redshift. Redshift isn't due to dispersion. If it was it would have some funky side effects on spectronomy measurements of the hydrogen 21 cm line

A New Theory of Motion and the Speed of Light
When In a vacuum the following electromagnetic relations for phase and group vecocities [math]\omega=ck [/math] [math]v=\frac{\omega}{k}=\frac{\partial\omega}{\partial k}=c[/math] The group velocity will equal the phase velocity both will equal c to all observers. The constant c is frequency independant. See dispersion relations given here https://en.m.wikipedia.org/wiki/Dispersion_relation

A New Theory of Motion and the Speed of Light
Unfortunately the OP isn't using any of the correct formulas to properly correlate phase velocity or group velocity in terms of the energy momentum equation. The phase velocity is not the velocity of the particle the group velocity is. https://en.m.wikipedia.org/wiki/Matter_wave Group velocity (equal to the particle's speed) should not be confused with phase velocity (equal to the product of the particle's frequency and its wavelength). In the case of a non-dispersive medium, they happen to be equal, but otherwise they are not. you can read further on that link but if you ever do the calculations you will find that for any particle less than c the phase velocity will always exceed c. However that is a product of its frequency and wavelength as noted by that link. It does not represent the velocity of the particle even in the case of photons. edit one side note phase velocity is not a true velocity but an apparent velocity it will not allow superluminal communication even if it's value exceeds c. You are dealing with group velocities in redshift equations whatever of the three primary types and not the phase velocity for the reasons above. Primary reason is the phase velocity carries no energy. Which is why it doesn't violate causality. (In a vacuum the phase velocity and the group velocity of light is equal) particularly since a vacuum is NOT a dispersive medium with a refractive index. Phase velocity has nothing to do with your claims above in point of detail a dispersive medium is precisely when the phase velocities become distinctive from the group group velocities. (As different wavelengths respond differently with the refractive index) primary example a prism.

Why do humans walk upright?
It's more accurate to not think of evolution as being caused by some factor. Rather the adaptations that best suit an environment is the more successful. There are also unsuccessful adaptations that do not suit an environment those get weeded out by survival of the fittest. The problem is thinking innovation can cause evolution, or the advantages an evolutionary change as being a cause regardless of what that advantage is. In essence evolution is the result of successful adaptations or mutations. No advantage gained by bipedalism causes the evolutionary change the advantages are the result of the successful changes.
-
Why do humans walk upright?
This is something the OP never seems to accept. Here is a pertinent question. Does evolution ever require a cause ? or does evolution simply result from miniscule changes that aid in survival advantages

Maybe you should study the endurance running hypothesis based on fossilized records of human evolution. https://en.m.wikipedia.org/wiki/Endurance_running_hypothesis

There is also studies showing that bipeds are more energy efficient and as a result have higher endurance. You also appear larger and more threatening Lol another question could be asked why did the tyrannosaurus rex walk on two legs it certainly wasn't for innovation reasons or use of its hands.

There is an advantage being able to spot predators early enough to run and flee in the right direction. That is undeniable a predator stalking already knows your location. I have repeated this numerous times now at what point do you listen to other view points ? It is a provable fact that many animals not just human will look to find their enemy. Nature is full of examples where sight is used to spot predators. Higher ground is a key to spotting predators early on as opposed to your eyes being blocked by foliage. That is literally common sense. What you refuse to understand is that there is never any single contributing factor in evolution. It is always a combination of miniscule advantages. Evolution is a slow gradual process

Your personal viewpoints means nothing in science try supplying evidence. I can quarantee if you hear a threatening sound you will try to see the source. It's in our very nature to identify the location of a threat.

How many experiences in the woods have you had ? I grew up in a small village in Northern Canada in grizzly country. That was one of the reasons I joined the Navy to make enough money to pay for my degrees. I've had numerous encounters with dangerous wildlife in my life. If you think hiding will help your wrong bears can smell you from several km's away and can locate you from scent alone. Your far better off spotting them as soon as possible. If a predator is stalking you he has already located you and getting into position for the kill.
