Do you have a clear definition of "real"?
If we do a measurement, which is certainly something real, then special relativity tells us what the result, also something real, will be. Since
in the widest sense, measurements are all we can ever do, special
relativity tells us all that we can know. Trying to go beyond that is

JanEvery few years NIST CODATA or the Particle Data Group,
releases an edition of the fundamental physical constants,
and every few years, the small ones get smaller.
Not just more precise: smaller.
These days the sky survey is finding a similar sort of thing, the universe gets
older and bigger ever year.
Now, how this relates to the Planck scale and the trans-Planckian, is as of matters of continuum mechanics in the quantum mechanics, and, in the
matters of the sampling/observer/measurement effects, where they are
always interactions, the sampling, observer, and measurement. I.e. formally there are no observations that aren't interactions, in an open system like physics.
Let's see here, leafing through Brown's "Planck: Driven by Vision, Broken by War".
"Planck is known as the father of quantum theory, and most textbooks give students
little more than that. He was German. He was a theoretical physicist (versus an
experimental, or a laboratory-based one), with a firm grasp of mathematics."
I'd earmarked this, "... most exciting to Max himself, and of great relevance to
physics still, he had proposed the idea of 'natural units', a system of measurements
based only on fundamental universal constants, with no bias from human preference,
convenience, or experience."
Now, that's laudable, these days we have what's "defined" and what follows what's
"derived", then though also there is "normalization" and "renormalization" in the
quantum, from particle/wave duality and the discrete/continuous nature of things
and that going back-and-forth makes "de-re-normalization" and another usual milieu,
just to indicate that "natural units" is overloaded both in terms of "fundamental physical
quantities", and, "algebraic treatment of perfect algebraic quantities".
" ... Planck time 5.39 e-44, ... Planck length 1.62e-35 ...."
(Here the atom's down around e-25, superstrings e-50, Angstroms and Plancks either side e-25.)
It talks about entropy and that's from thermo second law and Kelvin and so on,
where these days there is the adiabatic and nonadiabatic, and physics is an open
system, and thermo second law and entropy isn't always king, while agreeably it's "the usual definition of entropy, not the alternate definition also its opposite".
It talks about Max von Laue and then Clausius/Helmholtz/Hertz/Planck, but, it
should as well include Hooke, Kelvin, Rayleight, about discretization about quantum
theory, and about attenuation and dissipation or least action and equilibrium.
"None of my professors at the University has any understanding for [my thesis],
as I learned for a fact in my conversations with them." -- Planck
Planck's fixation on entropy is just another old "what goes up must come down",
but still, things go up, and time irreversibility is not the same thing as the absence
of organization and state or the input of intelligence what can make information.
There really is an entire dichotomy about first and second thermo law and there
really is an entire dichotomy about entropy and information. Planck is agreeably
a very opinionated linear thinker who doesn't address some of the issues in the
fact that for a "theoretical" physicist it's the "operationalist" sort, there are others.
"Helmholtz probably did not even read my paper at all. Kirchhoff expressly disapproved of its contents." -- Planck
"Starting in his middle age, Max had written increasingly as a would-be philosopher.
In particular he took up written combat with those of the 'positivist' persuasion.
... for Planck a belief in the absolute was the fundamental fuel that kept science running."
'In 1906, Planck published the first follow-up to Einstein's new theory, showing that
his own beloved entropy, as well as the principle of 'least action', -- a mathematical
statement of nature's efficiency - was preserved in the world of special relativity."
"E = (C lambda ^ -5) / ( e^(c/ lambda T) - 1 )"
"The big C and little c are just constants that help fine-tune the equation to match
the measure data. Such constants are the measurements a physics tailor makes when fitting a body of data with an outfit of mathematics."
Well that doesn't seem principled from the theoretical side.
"Planck knew that he would have to carry out a real fitting for the values of C and c
at some point."
"Planck pull the crucial mathematical pieces from a relatively old paper of Boltzmann's,
1877's 'On the Relation between the Second Law of Thermodynamics and the Theory of
Probability".
So, these days, various novelties in probability theory make for things like "the error record"
but generally for the profusion of non-standard techniques in probability and distribution
theory, this can help explain the adiabatic and nonadiabatic, and, differences, about why,
Planck's Boltzmann's Kelvin's Hooke's mathematics of approximations in numerical methods
in a statistical analysis, made some things easy for special relativity and electron physics together.
So anyways these days the "trans-Planckian" regime is about "running constants", and most of
the money for collider experiments, is just to release a more refined edition of the NIST CODATA
Particle Data Group constants, which, shrink each year. (According to higher energy or intensity
but energy, of experiment.)
Then in physics that's framed in "superstring theory" (its, scale) which is about "continuum mechanics"
and that "mathematics _owes_ physics more and better mathematics of infinities and infinitesimals,
in the continuous and discrete, to equip all the mathematics and probability theory, for the
ubiquitous success of mathematics in physics."
Then, in the very small, matters of scale even become geometrically fluid, in units, and dimensions,
in the arbitrarily small, and continuum mechanics.
Then, Planck is a great champion of thermo second law, which though, is seeing that because
physics is an open system, the "extra-local" is where it's getting that QM and GR don't "disbelieve"
each other, or that the modern "catastrophe" in physics is deconstructing and resolving the
same "ultraviolet catastrophe" and making better and superclassical models of particles,m
in their fields, or quantum field theory.

Maybe you can see though that "natural units" includes the conceit that quantization is more than a mathematical interpretation at all, that for Planck's stated goals, there's a deconstructive (and, self-re-organizing, constructive) account, what he has as a win, isn't the top (nor, the

But what was the state of the system before we did the measurement. Shouldn't our theories do more than just tell us what results we'll get
when we do a measurement, and have something to say about the state of
the system itself?
I suppose it would be nice if it did, but how could we ever test such a theory, when all we can do are measurements? A theory that goes beyond
what can be measured, even in principle, is philosophy.
He also raises some objections to the way we treat measurement devices,
and the things being measured, as if they're somehow fundamentally different. And, of course, we do. If we treat our measurement device as
a quantum object, then we need another non-quantum measurement device to observe the first one, and hence into an infinite regression.

In mathematics the study of "symmetry flex" is also called "quasi-invariant measure theory".
Also it's called continuity laws and as a superset of conservation laws, and physics is an open system.

In this way the force carriers among this sort of tripos exchange in the field that are really potential fields,
making for a neat descriptive framework of all the things, for a "grand unified theory" that's a
"unified field theory" that's a "gauge theory" that's a "quantum mechanics" and it's a "continuum mechanics".
This is that the kinetic and charge exchange in the magnetic, and light and the radiant nuclear are the

asymptotic freedom is like the cosmological constant and mass-energy equivalence in the rotational,

Yes, that's what's the most surprising.
Special relativity is a real and true physical tool that is remarkably internally and externally consistent as long as it is understood and
used correctly.
Flawless external and experimental coherence.
Internal and theoretical coherence as long as we agree to bow our heads

Special relativity isn't just about the maths, but also providing a consistent
*physical* model in every frame.
LarryYes, that's what's the most surprising.
Special relativity is a real and true physical tool that is remarkably internally and externally consistent as long as it is understood and used correctly.
Flawless external and experimental coherence.
Internal and theoretical coherence as long as we agree to bow our heads to those who understand it and explain it best.
The only flaw, ultimately, in all this is the men.

Hamilton is all Hamilton Jacobi these days.Einstein was trying to figure out how to re-write classical motion and effect so if youIt's like Einstein put it, "compound interest is a very strong force".
can figure it out then he was pretty interested in that.
Here's it's "Lagrangians" which is time.
Now, process control want's linear on the time, of course, but, you know, "non-scientific".
I guess "you know" means either "I don't know" or "I don't know ...".
Or "I'm trying to tell you".
I'm like "Einstein, how about Lagrangians, are Lagrangians alright" and he's like "great,
of course my differential system is also time, I told you about it".
Ah, it's what's "stochastic behavior".
So, you agree to play a game to pass the time, it's simple there are rules and events,
"let's play dice", and it's like, how we'll play the game is there will be an aspect of chance
that the only fair game is a game of all chance, there's skill and chance, including I suppose
the skill of planning a player, and taking or making plays, it's a dice game, it's fair because either
rolls the dice and they can compute the same distribution of the numbers and the rules are same
for both, or in turns, to be fair.
For example, a game where both put money down then for example "losers can quit" and "winners can quit".
There are basically games of chance, that to be fair involve only time.
So, anyways, the guy's like "I need to have a Free Will to have a random super-classical stochastic"
and it's like "sure, you have Free Will", and he's like "so how we'll play, is I'll just pick the number".
And it's like, "You can play that on yourself but me and Einstein are rolling dice."
So, eigenfunctions, are really great, they're directional. The integral equations and surface curves,
and the differential equations and solutions of systems where eigeinfunctions sit, in their eigen matrices
in their eigenvectors, make what results into usually systems of eigenfunctions, parameteric,
the geometry, you know, "coordinate free".
And it's like "how's that, Einstein" and he could be like "I'm good with Lagrangians".
Hamiltonians, Hamiltonian Jacobi Equations, Lagrangians. You want your Schwarz functions?"
And I could be like "Einstein do you think you will win?", and he's like "I've been having science try it out".
I'm like "Einstein, I demand my space contraction" and he's like "I know, I know, ...".
You are a crank.

Accelerating a very long ruler while keeping it rigid in its properYes. Born rigid motion requires varying accelerations all along the
frame requires a greater force applied to the trailing edge compared
to the leading edge so that the two ends approach one another in the
lab frame where its velocity increases:
length of an object being accelerated. They must be arranged to make the inter-atomic bonds all along the ruler not be strained, so the ruler has
a constant proper length (measured in its successive instantaneously co-moving inertial frames).
In the lab inertial frame, as the Born-rigid ruler is accelerated and increases its speed relative to the lab frame, the MEASUREMENTS of the ruler's length get successively shorter. This is NOT a "physical contraction", it is merely a change in MEASUREMENTS, and is due to the variation in the successive geometrical projections of the ruler's
constant proper length onto the measuring instruments at rest in the lab frame.
it physically contracts in the lab frame yet physically remainsNo! The change in length measurements performed in the lab frame is not
rigid in its proper frame.
any sort of "physical" change in the ruler -- calling it "physical" is a terrible pun on the word and just confuses both you and your readers.
Special relativity isn't just about the maths, but also providing a consistent *physical* model in every frame.Yes, but one must use words with consistent meanings, avoiding puns.

theorem from 2006 (aka. Free Will Theorem). Bell concludes his
article with:
"The big question, in my opinion, is which, if either, of these two
precise pictures [i.e. Bohm-de Broglie vs. Ghirardi-Rimini-Weber]
can be redeveloped in a Lorentz invariant way."
It looks like the Conway-Kochen theorem prevents any such theory
from existing. It's also interesting that this theorem does not
assume quantum mechnics, it only assumes three results which
can be verified by experiment.

If we do a measurement, which is certainly something real, then special relativity tells us what the result, also something real, will be. Since in the widest sense, measurements are all we can ever do, special relativity tells us all that we can know.

It's John Bell making a big deal about the 'measurement problem' as in:
what is a measurement? Is a measurement a conscious observation? The
world's leading young physicists, including Dirac and Heisenberg, came up with a model of Quantum mechanics, known as the Copenhagen school model;
and mathematically axiomatized by Von Neumann in his 1932 book:
Mathematical Foundations of Quantum Mechanics. This was debated very early on; but didn't matter according to Dirac, for example, as long as it's successful as a physical model that gives correct physical results.
This was before quantum field theory which today models particles as
states of a field that extends through out space and time. So the problem
IMO is that some people are stuck in the past; still trying to interpret
QM using a physical picture that is outdated and more limited. Understandably, they find it too difficult to invest their time and energy
in learning about quantum field theory and prefer to remain in their
comfort zone, philosophizing with their equally misguided peers. I have to admit... I haven't studied QM or QFT at even an undergraduate level so the above is just an opinion, ignorant compared to that of an expert ;)

The 'measurement problem' is inherent in quantum mechanics.

Tom RobertsThanks, Dr. Roberts.
It seems that's about where Penrose throws his hands in the air with "functional freedom",
or as I read that from his "Fashion, ..., in Physics".
The "classical" being just "a non-spin-statistical non-quantum-mechanical", still has that the
path between emitter and detector is "sum-of-histories" of Fermi/Dirac fermions or Bose/Einstein
bosons, the QM and QED what makes QCD. The "parastatistics" altogether is effectively as
if of a model of stochasticity, though with various laws of large numbers about what shows
up in quantum probabilities besides what's the mathematics today of classical probability
and maybe to the non-standard and with various expectations and uncertainties and laws
of large numbers what make counting arguments in the discrete and get normalized the
continuous, the probability.
It's like "how many drops is an inch of rain".
https://www.informationphilosopher.com/solutions/scientists/ballentine/
If Ballentine is basically "the statistical ensemble", I think most people already had this
besides whether they'd connected it to "real wave-function collapse" or "anything
different than a stochastic expectation", that "the ensemble" is just whatever adds up.
These days I think it's called "resonance theory" and "structural" or "molecular" chemistry.
(Vis-a-vis wave theory and atomic chemistry.)
Ballentine:
"This demonstrates that there is no conflict with quantum theory in thinking of a particle
as having definite (but, in general, unknown) values of both position and momentum,
contrary to an earlier interpretation of the uncertainty principle." -- 1970
Still though I'll disagree that the measurement isn't itself always interference.
The detector is an interface and there's an exchange and the exchange involves
the soliton and the instanton and the collapse and the particle at the exchange.
Or, a drop that's part of an inch of rain is rather gone before it can be counted,
the rain gauge has a meniscus.
Or, "any wave collapse makes a new one".
It seems that one of the things you point out is that "Multiple-Worlds Interpretation"
is not widely held by most practicing physicists. Then, for Penrose's hand-waving,
or about functional freedom, is to get figured how the whole "120 orders of magnitude"
disagreement these days is to fit gravity back in between GR and QM.
(And, neither is it necessary for "Free Will".)
"Dark Matter" then seems is just "rotating frames are independent", about that
the radial interface is like a wave and exchange, then also the space-contraction
of highly non-linear events, in what's otherwise the usually isotropic space-time,
with the only the very hint of anisotropy that makes fall gravity. ("Dark Matter"
has come up to "six sigmas", so, ....)
Or, I figure that as time proves that opinion, I will come out as right up front.
That's pretty easy though, picking some right giants.
It's a continuum mechanics....

'irreversible' is a CLASSICAL concept.
In classical electrodynamics, you can mathematically model a system of interacting charges using the retarded LW potentials for every charge
within the system. To time reverse it, you have to add an additional free field from outside the system which is the reversed radiation field from
the first system. Put another way: we can't reverse the radiation by reversing the velocities of the charges.
I suspect professional physicists have their differing opinions when
defining a measurement in QM, with the majority sticking with the
Copenhagen school with its claim that the observer is a necessary
condition for a measurement.
As an amateur, I find this definition to be
precise and to the point, leaving its philosophical outcomes for the philosophers to debate over.

When we do measurements, we get results.
But what was the state of the system before we did the measurement.
Shouldn't our theories do more than just tell us what results we'll
get when we do a measurement, and have something to say about the
state of the system itself?
I suppose it would be nice if it did, but how could we ever test
such a theory, when all we can do are measurements? A theory that
goes beyond what can be measured, even in principle, is philosophy.
He also raises some objections to the way we treat measurement
devices, and the things being measured, as if they're somehow
fundamentally different. And, of course, we do. If we treat our
measurement device as a quantum object, then we need another
non-quantum measurement device to observe the first one, and hence
into an infinite regression.

From my very casual overview of QM, reading the opinions of Bohr and Heisenberg etc,
I would answer: no, within the Copenhagen school. There is a wave function for an
observer reading the data that calculates the probability of it being some value read.
The computer etc doesn't have a wave function by itself.

'irreversible' is a CLASSICAL concept.
In classical electrodynamics, you can mathematically model a system of interacting charges using the retarded LW potentials for every charge within the system. To time reverse it, you have to add an additional free field from outside the system which is the reversed radiation field from the first system. Put another way: we can't reverse the radiation by reversing the velocities of the charges.
Sure, if you put it in by hand.
I'll one-up you with Wheelerâ€“Feynman electrodynamics.
I think I've misinterpreted your previous comment to RichD:
RichD: 'irreversible' is a CLASSICAL concept.
J Lodder: Where did you pick up this strange idea?
I thought you were implying that 'irreversible' isn't a classical concept; that classical physics is time reversible at its most fundamental level.
I suspect professional physicists have their differing opinions when defining a measurement in QM, with the majority sticking with the Copenhagen school with its claim that the observer is a necessary condition for a measurement.
The observer has been taken out of the story entirely, in practice.
All he observes are records that have already been made.
(without any human intervention)
They gather about a petabyte a day at LHC, or so I have been told.
The key phrase here for me is 'in practice' for applied physicists,
whereas John bell was in the theoretical division of Cern I believe.

One does not need QM to describe that -- classical electrodynamics' wave equation for EM radiation does just fine (for the situation with

Ah, it's like the fall gravity point, is the asymptotic freedom,
the other fall gravity point, occluding it in the universe,
its pressure term, eclipsing it.
Here it's now "impulse pressure" as a mathematical object,
one infinity long ray or spike area one called Dirac impulse amount,
in the vertical, and a unit area also one bead, opposite it the origin:
the linear and pressure term, the constants for fall terms,
it's not those under pressure.
"Eclipse darts: like jet bundles also droplets".
Does it have have vectors and arrows? Yes, it is vectors and arrows,
and complementing angle and the bivector with two arrows and double arrow, the area one together in pressure, pressure sort unit.
Here "the sort" is "the gradient", for example, there is one.
I.e. "momentum and the true centrifugal: is free and at peace".
"Free: as if frozen in a moment of time. At peace: stateful."
"Least action: fall gravity."
The idea that these are the terms gets into the states of matter,
solids and liquids and gases, airs, airs and mixtures of airs, water,
the ground, "the states of matter", Einstein has it as "a large differential system, differential meaning moving together in time, free and at peace".
Then he says "and inertial systems are in effect in units in time, kinetic".
Not that I would make him say so - if I could beat him to it.
I.e. he could be "well obviously that fully included in the entire intent of what I said".
I could smile at that, what is there to do but smile. I rely on Einstein completely
and bring him, though I say only exactly what he says and where.
So, with that for example any Einstein's spin foam, kinetic, then, the Einstein synchronizing,
is in effect in moving terms and in meeting terms. The disastrous failure effects but rather
the notion in upping the ceiling, the only reason spin foam is there is to wash all the way down,
Einstein's could be like "and my entire Dirac positronic sea that Dirac says, and spin foam,
come out as positronic sea and what must be in flow, whether internally there is more
the only less isotonic spin flow: that 'the spin flow's the outside flow, but it's only the
least draft, as what the draft indicates a head, of what could be air, that if it flows all
the way away, it obviously flows, Einstein's's "old quantum mechanics or new", Einstein's
along, "SR or GR".
So, tiny flow draft bundle, and, "the most usual notion of a push gravity, that the outside
universe on the outside of a body, equips the mechanism of force of pull gravity, that
is according to "mutual attraction and gravitation", that massy bodies according to
the theory exactly associate according to large inverse square, as what gravity is
the overall flow of orbits in weightless environments, which is according to "the Geodesy".
(The Geodesy is the world project that went around the world and established the variation,
in the location, of gravity's constant, the geodetic survey or the reference of the world,
at about pretty big distances or "an average of gravity over the Earth", they actually went
out I think and sort of surveyed must have had some "geodetic survey", it's effectively
that there's g and 9.8 meters per second then there's constant g under the square
root of that, measured, it was found to vary only in about the last few units, or
9. dot dot to 9. dot dot, mostly the same but up and down in hundredths and tenths,
gives a constant to the "outside flow", this spin foam in quantum gravity, which in
effect leaves bodies internally weightless.)
Einstein's as "spin foam? Sure, why no spin foam or spin foam, it's the same to my
kinetic or rather inertial systems it rinses the spin foam as gravity is the law. Yes
it's same as any other flow gradient out terms."
I.e., the rest of science is "not Einstein's", "Am I in a fishbowl, this is my bird cage."
It's like "Einstein, at the end of all your theory, I got a picture", then he's like
"it's your picture".
Similarly Einstein could be like "you know I only have two definitions and one of
them is kinetic, anything we both know doesn't apply doesn't apply, I could be
lying if I said I never said the other way - of course as you would know that yourself.
And thusly "Einstein: "SR _or_ GR".
Here it's GR, then SR.
But, here just means from the source, of what to SR is the image, the picture.
Which is also what it looks like, and seeing it.
The light's are out in GR: and really are out, that absorbance, of light, must be under "sustained exposure".
This is not say much "rays" as "a ray, a beam, rays".
Light-like, ....
And Einstein's as "see, light speed", while at the same time, as it absorbs, is continued reflection, what absorbed, in the cloud.
Einstein: "What's your theorem?" "Just remove my name, it's their theorem."
See, when Einstein's theories, become theory, besides his theory, is the theories together, and extended, and theories besides each other, like
SR and GR, where "SR is light-like at all because it's the constant", and
GR is "this is a kinetic world for example electrodifferential", for example a large wheel built into a mountain and using lightning to spin it around.
So, now it: "Einstein: Einstein's theories: Special Relativity, light speed is
constant, General Relativity: inertial systems are massy bodies, either or both, together my way, Maxwell from rest also at c, in a perfect conductor".
I think if Einstein was alive today, he'd say "what's that tremendous noise".
Then at night image, "the sky is entirely filled with satellites and the city light
leaves no stars", Einstein today, "My God cars are giant in the future."
"How's my theory doing?" -- what I like to imagine Einstein would say,
if I hope a robot sort of Einstein, which I do not, except "Einstein, Einstein's theories, dot dot dot".
I mean in all good faith he has "those are exactly the terms", that
images pass at passing distance and looks pass at looking distance.
I.e., images pass at 120, look passes at 60, two-way 60, miles per hours, any two trains or two cars passing two-way, passing, each at 60.
Then, to catch up to a train, or pass the coffee from one train to
the other train, is that the train's do not meet at all, they pass,
or would theoretically compress them to their mirror image,
it's the usual mode of civic cooperation the utter importance of
going opposite ways in the same way, not looking at the pass
but with the eyes on the road.
Still, taking the pass, involves only taking a look, then a look
over a limited moment or a snapshot, "passing at 60 miles per hour",
about how to pass a cup of coffee, or tea, from the train going one-way
to the train going the other way.
The idea is that the transfer happens as close to the front as possible, reaching for the look, the automatic waiter is standing exactly where there will
pass or meet, that of course despite how fast the actual pass is, theoretically the automatic waiter has time whle everything else on
the car is frozen in time, passing, as they fully pass each other,
obviously symmetrical throughout, identical train cars, as if both
were at the station, only one instant for the duration of "slowly passing", which of course is length over 120, miles per hour.
I.e., passing in opposite direction, they are already miles apart,
looking back.
Of course, it's never actually frozen in time unless the direction or passage of cars, are going same or different direction, how they
catch up and slow down. No active control look, here is that the
information from the look, is directly connected to all the terms
of the steer, according to that "any coffee cup so passed would
get a 120 MPH acceleration", with acceleration spread out in the
abstract time.
Then, this is a usual brief second or "0.2, about a fifth of a second,
or a tenth, look time, where 2 is reaction time", that is whether longer
or shorter looks, affect reactions, what be the reactions as "steer" and "stop". That is, the information, according to the time, has that
"5 mph could pass the cup, maybe not 10 mph".
Or "everybody stops at the window."
There is a general idea though that you can get on the train,
accelerate with the train, then walk into the car, and get the
cup of coffee, and get off when it stops, that getting on and
getting off, the train, is defined as an entire train car or any two
cars or carriers, is that objects that accelerate together rest
together. (And decelerate, rest together, falling in orbit together,
parting and meeting, rest together. Meeting in passing,
I.e., two twins that pass each other regularly, also come to
rest, that combined acceleration and rest accumulates.
If they stop, ....
And when!
I know I can make pressure in radio space with an antenna in a vacuum, ....
(It directly attenuates in the air.)
These days it's called current.
"Time is always stopped. And then it goes...."
Time only slows, ..., and then it goes.
Time always stops when any two objects pass.
Once!
Then, information seems in looks, where looks are directional.
"Sensory information."
So, Einstein and twin primes is we are all twin primes of course, and work out in effect whether elapsed
that the twin prime of the planets have not so much necessarily things could go so fast to change the times,
as that there are times that are very very very long ago.
In SR acceleration it's that "SR's acceleration potential is zero".
It's kinetic, when kinetic is inertial, ..., that though can also be added, in the sense of that
"objects in GR are free if they don't emit", putting objects into the theory "yes these are
GR's objects, I expect same when the light's on", in fact you can compute them, about,
while also my SR interpretation has potential-free imaging, free of potentials or as the
all classical, indeed to the limits of the theory.
The difference between running it and having one? A routine?
So, the reason why I offer this, and it's varied: here is that "objects that accelerate together
are in time together".
"Fall gravity: free weightless environment."
