Find any reference to fictitious forces and for a theory

and anything at all to do with the plainly empirical or
tribological with regards to our grandly theoretical,

"momentum" with regards to resistance to changes in motion
and resistance to changes in rest, as with regards to
weight and as with regards to heft, have rotated each
few hundred years, as with regards to the great schism
whence Newton's vis-motrix, as with regards to the vis-insita
and Leibnitz' vis-viva, as what for example can be read into
from the Wikipedia on conservation of _energy_ and
conservation
of _momentum_ up to today, where for example, the
"infinitely- many
higher orders of theoretical acceleration are both formally
non-zero and vanishing" because "zero meters/second
equals infinity seconds/meter".

Much like the theories of "fall", "shadow", or
"push" gravity, or the "shadow" or "umbral"
gravity and for theories of real supergravity,
as after Fatio and LeSage, as of theories of
"pull" or "suck" gravity of Newton and the
"rubber-sheet" or "down" gravity of Einstein,
then the theories of vortices like DesCartes
and Kelvin, and others, help reflect on the
rectilinear and curvilinear, and flat and round,
as with regards to deconstructive accounts of
usual unstated assumptions and the severe

with regards to modern theories of mechanics.

You know, zero meters per second is infinity seconds per meter,
and, any change of anything in motion has associated the
infinitely-many higher orders of acceleration, and,
it's rather underdefined and even undefined yet very
obviously clearly is an aspect of the mathematical model,
that Galileo's and Newton's laws of motion, sort of are
only a "principal branch" as it were, and, don't quite suffice.

Of course anything that would add infinitely-many higher
orders of acceleration mathematically to the theory,
of mechanics, the theory, would have to result being
exactly being the same as Galilean and Newtonian,
"in the limit", and for example with regards to
Lorentzians and these kinds of things.

It's sort of similar with adding more and better
infinities and infinitesimals to mathematics.
The continuous dynamics of continuous motion
though and its mechanics, is a few layers above
a plain concept of the continuum, as with regards
to something like a strong mathematical platonism's
mathematical universe, being that making advances
in physics involves making advances in mathematics.

Actually, there's an idea that one way to conceive
the universe, is, as a mathematical continuum, that
these days that's what's called "holograph", or "hologram",
the idea that one mathematical continuum is big enough
to have a number, for each thing, and relation in things.

Then, for example, Euclidean space, and, maybe not
Minkowski space, have it that there's only a ray
of time, or 3 + 1/2, with three space dimensions,
rolling and curled up, in the infinities and the
infinitesimals, one continuum.

It might even be reasonable to explain sort of why
there are three dimensions in a mathematical universe
of the space-like, simply courtesy properties of numbers,
because "least action and a gradient" is about the
easiest way to say "it is what it is, and it will
be what it will be".

People make a lot of the complex, and also the

there are also approaches like Kodaira and Zariski,

Then the idea that there is a numerical resource,
a continuum, that just sort of naturally results
three dimensions and a ray of time, and also then
as with regards to tetrads and information in
the space-time, the "Space-Time", with its contents,
is a thing actually looking to equip a mathematical
model as being a resource and book-kept in this way,
about deriving most of the theory from least,
and that that's a very principled approach.

The "time parity" has never been falsified in physics,
so there's never any real "negative time" in physics
as a quantity, so, it's considered a real quantity.
When the perspective/projection is unduly rigid instead
of optical, geometric instead of optical, then it lets out,
yet, that is a limitation of the mathematical model not
an ever falsified aspect of the physical model.

Now other time domains may exist, where time there is locally positive,

This is possible, because the very word 'negative' makes sense only for

It's like the other day, there was an article, and it purported
"negative time demonstrated", which of course would violate causality,
then it looks like it's as of an Aspect-type or Aspect-like experiment,
where Alain Aspect, makes an articulated beam array, in the photonic,
what results that an information arrives as "at once" and, "zero time",
as it were, that "information is free, yet metered", that though
yet still not reflecting, "negative time". Aspect's though
does _not_ have "negative time".
>
Then it's like looking at something like that, it's like,
"well in our model, there's never zero time, so, the way
we see what according to that coherent frame is zero time,
which in our theory isn't coherent and so yet a time difference
the same experiment, results it must be _negative time_".
>
>
And it's like, "I get what you mean that's not coherent."
It's like "you don't even have the words in your theory
for zero time thusly it bleeds into your numbers negative".
Of course it never went _backwards_ in time and never
violated what most-all have as causality or otherwise
went about making false statements about physics.

It's almost a universal consideration that
physics is a universal consideration, with regards
to that of course it's arbitrarily un-falsifiable any
matters of "higher-orders of organization", it's also
immaterial, as "the universal consideration is a universal
consideration".

Then, these ideas of symmetry, what result the notions of
mirrors and the reflection and incidence of reflection in
what results the optical in the optical, and also about
the vorticial that is the non-linear part of "equal and
opposite reaction", the law of physics, then makes for
that indeed invariance of conservation law and Noether's
theorem about that being an abstract what we call continuum
law or continuity law most usually, though some most usually
call symmetries and others conservations and others invariances,
that here it's that conservation laws are continuity laws,
then that what can result as symmetry-flex, is otherwise
for the regularities of symmetries, invariances, conservation.

The "information is free, if metered" bit reflects on that
usually the idea is that according to the invariances under
the theories of relativity, that information can never go
faster than c, which given the L-principle is a universal
constant. So, the idea is that in the space-frame terms,
actually the space-frame can be contrived, so that what
happens, there's established any linearity and a guide-lode
at the center, then that the guide-lode's motion, also
advises the motion twice as far away.

This is that "information is fundamentally free",
"if metered", and specifically by the carriage
of light otherwise, and even "asymptotically free".

The new "negative time" bit is described as a sort
of condensed-matter physics thing where there's
just sort of some ultra-cold rubidium which has its
own sort of super-fluid regime with regards to
condensed-matter physics, so anyways it's just
shooting photons through that, then saying that
the photons arrive out the other side at light
speed yet also appear to displace or "be absorbed",
where that's assigning something that's not so.
Nothing happens faster than "light speed" there
the photons is what's not going on.
That's an altogether different concept of course
that there's a clock hypothesis and indeed that
out past c there's c_g and it reflects the Newtonian
and gravitational waves have immediate components
and gravitational waves have luminous components.
Of course the most modern ephemeris about Earth
is Parameterized Post-Newtonian where c_g > c,
and of course the force of gravity always points
at the source not the image, and GR is in front of SR,
and SR has that light is fleeting, and SR's spacial is local,
and so on, here according to JPL and Einstein on Einstein.
