Clearly a meter stick image that is seen as a result of received EM radiation is NOT a meter stick object made of atoms. Yet mental object recognition capabilities allow the received and processed information be associated with such an object. That object recognition capability is useful for an organism navigating and surviving within its environment. However to equate the output image with the object made of atoms is a category error. There is no way a seen car(image) that I can measure to be 1 inch in length with my near ruler is a car object in which full sized people made of atoms can fit. It follows, the distant image meter stick length can be measured by comparison with the length of the image of the near object meter stick.The seen length being a relative measurement. The distant image size varies like the size of the elephant mentioned in the article. One has to consider which space the shape is in. Is it an invariant object shape in external space or a scale variant output image that appears in a space-time image environment.( Or is it in an abstract mathematical space in which case 'objects' might be scale variant or invariant depending on how they are modelled to be. Lubos Motl seems to have been solely considering the first kind of space and object. Either that or he was falling into the category error of equating image with object and mentally applying the material object's full size to the image of smaller size and claiming the image size to be invariant-it is clearly not.)
Is Gravity Time's Archer?
I discussed the same problem with Julian Barbour a few years ago:

Barbour claims that absolute simultaneity and Einstein's 1905 constant-speed-of-light postulate are compatible and I disagree of course. Any reasonable scientist knows Barbour is wrong and yet... the prize went to him while I had to leave the contest.
Pentcho Valev
Pentcho,
Whether Barbour is right or wrong, his program is compatible with Einstein. In fact, shape dynamics is an attempt to explain all physical constants. It is no more reasonable to reject the empirically measured constant speed of light, than it is to reject the first principle of thermodynamics.
How are you coming on that refraction problem?

We know that the amount of matter of pra-kilogram on the Earth surface and on the Mars surface is the same. Which is value of inertial mass of pra-kilogram on the Mars surface?Attachment #1: Origin_of_Energy_Mass_Gravity_and_Antigravity.pdf
This provides the fundamental understanding of gravity: INERTIAL RESISTANCE is proportional to gravitational force/energy. This is the most fundamental law/truth in all of physics. It is all about balancing inertia and gravity. IT IS THE FUNDAMENTAL UNIFICATION OF PHYSICS. Think about it.
You physicists do not understand gravity AND inertia. You are definitively defeated by me, and for all time.
There is alot to consider here. It takes time to absorb it all. We also have the zero distance (NO EXPERIENCE, FULL INERTIA, outer space), MIDDLE DISTANCE (HALF INERTIA AND HALF GRAVITY), and full distance (FULL GRAVITY, FULL EXPERIENCE, FULLY VISIBLE) matter to consider. (Middle and full distance are in balance.) That is super important. The ultimate unification (AND understanding) of physics balances being and experience. There is no getting around this. Dream physics is THOROUGHLY consistent with this: Gravitational force/energy is proportional to inertial resistance. Consider the words "INERTIAL RESISTANCE" very carefully in relation to photons AND the sun. There is no inconsistency, incompleteness, or confusion with what I have proven and demonstrated. I have shown a most important relation/balance between inertia and gravity throughout. THE WORDS "INERTIAL RESISTANCE" ARE SUPERB. You have to really think about it. This is totally true: Gravitational force/energy is proportional to inertial resistance. IT IS A GIGANTIC LAW.
"INERTIAL RESISTANCE" HAS GREAT AND MOST EFFECTIVE SIGNIFICANCE/MEANING.
It is clear that the Earth/ground involves THE/our experience of full gravity, and it is clearly then balanced with inertia. (Moreover, its composition is ultimately ELECTRICAL in origin.) The MIDDLE DISTANCE (as defined) is also balanced when we are standing on the Earth/ground. Why would Einstein not consider the man on the Earth/ground if he is talking about GRAVITY ? We want to balance (or match up) being and experience. MIDDLE DISTANCE and FULL DISTANCE ARE IN BALANCE.
The gravity is understood as balancing/cancelling at HALF (as/with the MIDDLE DISTANCE), as I defined it. So, the falling man feels no gravity due to this: Invisible AND visible space in FUNDAMENTAL equilibrium and balance is the MIDDLE DISTANCE in/of space consistent with half gravity and half inertia.
EINSTEIN IS DEFEATED:
Think about the Sun AND photons. INERTIAL RESISTANCE is proportional to gravitational force/energy is the most fundamental law/truth in physics. ENERGY HAS GRAVITY. I defeated Einstein and the modern physicists by showing a fundamental balance/relation that involves gravity and inertia as this applies to the various and fundamental/significant/extensive manifestations of space. My unification of physics/physical reality/physical experience is consistent, EXTENSIVE, clear, and proven. IT IS GIGANTIC.
Gravitational force/energy is proportional to INERTIAL RESISTANCE. Think of how this applies to black holes (and the gravity). Outer space involves full inertia. Outer space is fully invisible, and it is black. INERTIAL RESISTANCE is proportional to gravitational force/energy. This most fundamental law/TRUTH of physics also CLEARLY explains black holes. THINK ABOUT IT. MAGNIFICENT !!!
I HAVE FUNDAMENTALLY UNIFIED PHYSICS.
I AM THE FUNDAMENTALLY SUPERIOR THINKER TO EINSTEIN. EINSTEIN NEVER UNDERSTOOD GRAVITY AND INERTIA. THAT IS WHERE I PULVERIZED THEM ALL.
INERTIAL RESISTANCE is proportional to gravitational force/energy is absolutely correct. Energy has gravity. Consider the Sun AND photons. The Sun has balanced gravity, inertia, and electromagnetism in accordance with this law/truth.
Outer space involves full inertia. It is fully invisible, and it is black. INERTIAL RESISTANCE is proportional to gravitational force/energy. This is true in the case of black holes. Most importantly, this law/truth balances gravity and inertia.
Consider the/our experience of the full gravity of the Earth/ground. This also involves balanced inertia. The Earth is held up against gravitational collapse by the stiffness of its material, ultimately ELECTRICAL in origin. So, we also have gravity, inertia, and electromagnetism in balance here.
Black holes involve full inertia (inertial resistance) that is in balance with full gravity. (Outer space involves full inertia. It is fully invisible, and it is black.) The inertial resistance is understood as involving the gravity. This is the most fundamental law/truth in all of physics: INERTIAL RESISTANCE is proportional to gravitational force/energy.

JULIAN BARBOUR AND TIME聽
I do not deny existence of time as Barbour is doing. He wins FQXI research on origin of time few years ago. His article was published at Arxiv. Barbour tries to abolish time from physics, so in his article there is no symbol t for time.聽
This is funny and shows Barbour did not get the point regarding what is time. It is true time does not exists as a physical reality in which changes take time. Barbour got that point, but he went in another extreme thinking that time does not exist at all. He is wrong. Time is not fundamental physical reality in which changes take聽place, time is merely numerical order of changes taking place in space.聽
FQXI spend about 1,5 millions聽of Dollars for advanced research on time and Barbour article is the main result of this investment. It is sad to see to spend so much money for such a meaningless result as is Barbour paper. I also apply but I did not get 1 Dollar. Because I do not belong any official scientific organization. What a nonsense is this. About time there was written so much crap from the side of established scientist with no result.聽
Now FQXI will spend few millions for research on the origin of the observer. I also apply, I send him my papers, but they answer me I'm not coming in consideration for grant. Again a lot of money will be spent with no result. Because this so-called 聽"established" scientists are "chewing" in their minds this old paradigm of physics with "space-time" (where time is 4th dimension" which is pure failure in which physics cannot progress.聽

I encourage you to avoid the sour grapes and yet I also encourage you to keep jousting against the windmill's of pedagogy. You have model, I have a different model, and there are a large number of other people with different models.
Mainstream science realizes that uniting gravity and charge forces will require a very different approach and that mainstream science remains trapped in a blind alley of its own pedagogy. However, if it were so easy to find a path out of the local minimum in which science currently finds itself, it would have happened long ago.
I like your DQV (dynamic quantum vacuum) approach since it comes down to an aether and that is my approach as well in aethertime. However, since you still believe in both time and space, your DQV aether will necessarily have all of the same pathologies as does the current quantum foam of spacetime. Also, it is not clear what role phase and coherence has with DQV aether, which of course is how any aether will be a quantum gravity as well as quantum charge. In other words, where is the Schrödinger equation?
Let's face it. You have not really made a very strong case for the usefulness of DQV aether for addressing the issues of cosmology that don't already have explanations. In other words, simply saying that DQV explains dark matter is not as useful as actually doing a calculation that shows that DQV aether shows how a galaxy rotates. Replacing dark matter with another equally mysterious substance called DQV aether hardly seems that useful.
DQV aether ? I named gravitoetherton super fluid. Can it be the dark energy and dark matter, we are looking for. If we assume our space is an exotic super fluid consisting of many dark /white particles swirling and whirling and creating curves of Einstein around matter ? The water around a sink hole rotates with corks floating and near the sink hole, we see straight flow to wards the hole. The planets are just happened to be their and rotating in the fluid after correcting their placement from rotational centrifugal. No Newtonian force or curvature of space-time , simply flowing with the fluid. Are basically making mistake with force of gravity. Gravitons exist with a mass in the super fluid. Galactic rotation curve is due to non isotropic distribution of gravitons from center of galaxy to outer periphery. Because rotational centrifuging may distribute the gravitons in the fluid to sustain the disk and produce a curve as seen by Dr. Rubin. If gravity is not potential and not fundamental but emergent , then in my opinion it is emergent at two levels. Molecular push give us classical gravity where as reaction with color quarks inside protons and neutrons can give rise to quantum gravity. It may be worthwhile to qualify quantum gravity as strong nuclear force without assuming it a new fundamental force. We may not need strong nuclear force. Planck level action and reaction is not very much known and experiments in LHC can bring out the properties of graviton. However , I have produced a paper giving some ideas of our universe and parallel universe etc etc for scientific community to explore further.

You Know Amrit, it is just that people must eat..It exists jobs,funds, responsabilities,....The life is not easy and people must publish pappers.Of course the FQXI community is a kind of private team but they are transparent and permit to all to put their ideas for the first X on a totally transparent Platform.It is revolutionary in fact.The grants or this or that are not really important you know Amrit,the sciences ,them, yes are important.All deterministic work or theory one day is always recogised by the generalists and rationalists.It is the most important.The grants are a tool of dynamization of systems of research and it is well like that.Of course sometimes the competition is well, sometimes no.Thecomplementarity is better.Best Regards
Sometimes I imagine the potential if scientists were focalised on global problems without competition but just to find global adapted deterministic and universal solutions.We could solve this planet in some years....
