Finally! Someone is at least thinking about running an experiment that will
test the gravitational polarity of antimatter. It's about time!  I have
predicted since at least the 1980's that researchers will get some truly
surprising results when they finally do see how antimater behaves. According
to my theroy, "Analysis of Gravity in Mass-Energy Systems", there is at
least one form of  'antimatter' that does indeed have a positive inertial
mass and a negative gravitational mass.  Remember folks, you heard it here
first. Once modern science finally pulls its head out of its collective a.s 
concerning gravity, many of our currently popular ideas will be quickly
rewritten. Even 25 years ago, my theory correctly predicted baryon
conservation - and gave the reason why. I also was amongst the first to
describe the swiss-cheese structure of matter distribution in the universe,
and give a reason why. I also found out why there appears to be a matter -
antimatter assymmetry in the universe, and show how it is just an illusion
brought about by the way the two forms of mass self interact. Yes indeed,
ranging from quantum mechanics, to cosmogony, the truths about antimatter
are truly enlightening! Of course, I probably wont get the Nobel for being
first.... oh well. I got out of the field in the 1990's to begin my work on
Superluminal Communications Systems,  and have had spectacular success going
where no human truly has gone before!

There have been ideas and dreams of doing this for many years. But as
the article says, there are now two credible proposals being prepared. I
am a member of the team preparing a proposal at Fermilab.

BTW nobody who understands modern physics expects an antimatter apple to
"fall up". This is so because for ordinary matter >95% of the mass is
due to binding energy, kinetic energy of constituents, and the gluon
field -- all of these things are exactly the same for matter and
antimatter, and there's no plausible mechanism to cause them to behave
differently with respect to gravity. So if gravity couples differently
to quarks and leptons than to antiquarks and antileptons, we expect a
difference on the order of 1%. There ARE several plausible extensions to
the standard model and GR that predict such a difference. This gives a
rather strong requirement on the resolution of any viable experiment.

I don't envy you - limiting EM effects even for  a net neutral anti atom is
not going to be easy. But the experiment needs to be done.

Good. Then when your bit of antimatter is repelled by the earth's gravity
field the way I say it will be, there will be no confusion as to who was
saying what for the past 25 years. If I'm wrong, I am positive there will be
many here who will mash my face in my failed predicition, so if there is
even an ounce of integrity in those that call  themselves scientists, then I
expect my theory to be taken more seriously as well.

Gravity has absolutly nothing to do with the 'energy ' of a particle.  This
is the fallicy in your assumption that there can be at best a small
percentage difference between
matter and antimatter. Gravity is a purely quantum guage field to the
probability distribution psi. This idea has been unpopular since I proposed
it in the 1980's , but the evidence keeps piling up that it's right. The
latest is the work of  Ben Wandelt at the UIUC concerning the promordial
non-gaussianity in the WMAP 3 year data to practically hand over the proof
needed, if  it's correct. Fact is my model predicts an equal amount of
matter and antimatter created, with a resulting net gravitational wave
variability of zero. The net gravitational charge of the universe is exactly
zero, so looking for evidence of gravity waves in the early universe will be
fruitless. There is no other theory I am aware of that makes this prediciton
, with the potential to be tested. From the emergence of structure in the
universe, to baryon conservation, to a mechanism that describes how we find
ourselves living in a universe made mostly of matter, my theory has so far
not failed. And it's even straight forward enough to be understood by a
(smart) high-school student...

It is quite obvious there are many things we don't
understand about our Universe, like:
- Galaxy flat rotation curves,
- Spiral galaxy central bar (rigid like),
- Why all celestial bodies are themselves rotating and
also around something else,
- The actual theory (of Relativity) is based on the Equivalence
Principle that avoids any inertia understanding and, therefore,
doesn't consider rotating bodies as gyroscopes. Because
of that always fails when rotation are involved.
- Black holes with jets,
- and so on.

Does your theory solve any of the above issues?

From what I've read so far, the experiment can once and
for all tell if there is an Aether, or not, and if Relativity is
right or wrong (plus many bullshit).
Therefore, the experiment is very important. Much more
important then Higgs particle.

The experiment looks very easy.
Gravity and Electromagnetism don't mix and the excuses
given are nonsense. All we need to do is to see where
the antimatter wants to go, up or down.
Looks like scientific community is afraid.

How do you expect to identify the force of gravity in the presence of EM
forces some 10^20 times larger?

> Looks like scientific community is afraid.

You clearly do not understand the scientific community. This experiment
has not been done not because anybody is "afraid", but rather because
the experiment is DIFFICULT.

If it is difficult all you need is an imaginative engineer.
Build a linear exit section on the particle accelerator
to perform the experiment.
Divide the linear section into two.
First section is a de-accelerator to lower antimatter
speed. This first section have large braking EM forces.
Second section is free of EM forces and made of a set
of detectors (gratings) where the antimatter must fall at
different rates according to its linear speed.
All this in vacuum as usual.

Let's ask the simple question:

How do you intend to slow down a neutral atom?

The same way they do it for neutrons? I have read at least
3 articles talking about gravitational selection of slow neutrons.
There you can see them dropping in a parabola curve, just like
any other matter.
Expecting an antimatter atom to behave in any other way is just
wishful thinking.
Also, what adds electric charge to something falling?
It certainly wont slow down something dropping, the influence of
a mirror charge developing in a ground plane would just pull the
atom down faster.
The whole difficulty in testing an antimatter atom falling,
is the difficulty of tracking a single atom.
It is possible to trap and slow down a single atom ,
using laser light etc., and maybe you can time the destruction
explosion after you release the trapped antimatter atom, when it
drops in a highly vacuumed column.

That's quite difficult (though it can be done). But it is not feasible
for our situation at Fermilab. We decelerate the antiprotons into a
Penning trap designed to hold charged particles. We then put positrons
into a different region of the same trap. We then lower the potential
barrier for the antiprotons and make them travel through the positron
cloud. As the antiproton has a much larger mass than the positron,
whenever the two come together the resulting antihydrogen atom has
essentially the same momentum as the antiproton; as it is neutral it is
not trapped and easily exits the trap. This is all done at a temperature
of a few milli-Kelvin so the speeds are on the order of km/s.

> The whole difficulty in testing an antimatter atom falling,
> is the difficulty of tracking a single atom.

No, that's the easy part, as the antihydrogen annihilates whenever it
hits normal matter: the resulting particles have energies of hundreds of
MeV and are easily detectable. Of course you only get one such
observation per atom, so it is necessary to provide a pulsed beam of
antihydrogen with known position and time. For our experiment the timing
comes from manipulating the electrostatic potentials of the trap, and
the position information comes from transmission gratings with line size
of 1 micron (anti-H atoms either get through or annihilate in the first
grating, the second grating makes an interference pattern, and a third
grating is used as a detector of that interference pattern).

While much of that is technically challenging, the hard part is trapping
the antiprotons and cooling them so they remain in the trap with
acceptable transverse and longitudinal emittances.

"possible" does not mean "feasible". This isn't feasible.

Tom,
Is it feasable to change the spin axis of a single particle, or
will it sorta keep one spin axis only?

In other words, could you make a particle spin horizontally
like a golfball would and then send it off to collide?

Particles with a magnetic moment can be oriented
as desired by applying a suitable field.

And when you stop such a field, it pops back to
align with the universe.

The orientations tend to randomize by thermal
excitation (jostling, vibrating, rotating).  
While they are still influenced by whatever local
fields obtain, kinetic randomization tends to
swamp the effects of any but strong fields.

This is why so many of the physical experiments
done in this area are performed at very cold
temperatures (millikelvins).

Actually the real meaning of it being simple stuff is true,
It is just a ton of simple stuff, and because there is so much simple
stuff, it makes it complicated.

Yes compression,friction,force, etc
in all sorts of manners measuring bit by bit by bit etc..
It is mechanics at the most basic still and the very most
you can find about how it works"
If you take it apart carefully, you know how it works.
You don't go "smashin it up" to see how it works..

No,
I don't think "IT" is simple,
I think each small part of it is basically simple
It is "ALL" basic mechanics if you are doing it correctly.
but just "TONS of basic already known equations worth" of it
Hence the term "quantum - mechanics"

Simple, no. But it *is* understandable. If you go back to the first puzzle
in quantum mechanics, which is the double slit experiment, you have a
perfect example of what I mean. Even Feynman has said that this is the only
puzzle in QM, by which he meant that if you could conceptually understand
what was going on you would have solved QM. He was wrong, but not for the
reasons he thought.  On my web site, I give a 'simple' explanation for the
n-slit experiment which shows how conceptual a theory it can be once you
know all the pieces - it only seems beyond human ken because they only teach
essentially half the theory in school. How understandable it is depends on
how open you are to understanding..... it's kind of a Zen thing :-)

Once you 'understand', and can see how childishly simple building even a
superluminal communicator is, let alone fully understanding the double slit
experiment... even then, you can see the next level of questions that need
to be asked, and realize just how much you don't know in the grand scheme of
things...

Antimatter is energy rotating/precessing at 1:2  just
like matter, but it precesses the opposite way.
Since our galaxy precesses only one way, most
of the matter making it up also precesses only one way.
(But is it the same as or the opposite of the galaxy?)

Correct. Verifying a technology ready for economic development is not the

Spoken like a person who hasn't a clue to what they're rattleing on about.
If only it were as simple as you make it out to be... Like Tom Roberts reply
as to how difficult it is to run an experiment showing the gravitational
polarity of antimatter,  it can't be done in the wrong way without negative
consequences. As a tiny example, the oscillators I use for generating the P2
pipeline - the actual quantum link connecting the two devices in a
superluminal mode- need to be so spectrally pure that as of 2002 the u.s.
federal government considers them to be 'munitions' and subject to export
restrictions. If I were to, say, post a schematic of an actual device, I
could be breaking the law and get arrested. Before I could even do such a
simple thing as post a design, I would need to get it cleared with a lawyer
first, and that takes money I don't have. If I have to file forms with the
Fed, then forget it - I can just imagine how long I'd be free to talk about
my device if anyone in the government thought for even a millisecond that it
was for real... even as it is, my small web site regularly gets harvested by
several governmental sites. That's why I have not activated the last two
links on my homepage.

Post and "poast" mean almost exactly the same thing, with just a very
slight difference -- poasting is much more "leet".

We intend to submit a proposal by November 1, 2008. If we miss that date
we will have to wait until the spring/summer meeting of the Program
Advisory Committee. As the experiment is time limited by the impending
shutdown of the Tevatron in 2010, such a delay could be a problem, so we
will try hard to avoid it. We think we can beat that deadline by about a
year, but will probably be hard-pressed to take data before late 2010 in
even the best scenario.

Unlike virtually every other experiment at Fermilab, this one will be
limited by systematic errors, not statistics. Most of those we will work
on BEFORE funding, as we can do that with normal hydrogen and already
have most of the non-beamline equipment (the last piece arrived at
Fermilab last month and two grad students are setting it up now in a
different lab). Once we get it working at the accelerator and have tuned
up the antiproton beam, our estimates are that one beam pulse will give
sufficient statistics to be systematic limited (so think of several
weeks :-)). Data analysis and publication should be only a few months.

I am talking about what causes it, not how it behaves. But still, the reason
gravity can do real work is because of what causes it... probability
conservation is a more fundamental quantity than 'energy' conservation, and
is the reason why we have conservation laws to begin with. When you are
talking about kinetic or potential energy, you are really taking a step away
from the more fundamental reasons why things behave the way they do. It
muddies the waters.

The truth is:
- Modern physics don't understand inertia, because
Einstein had no clue on what a gyroscope is.
- The mechanism you fail to see is - INERTIA.

When a particle and an antiparticle meet, no matter the
speed then meet, they are annihilated - NO INERTIA
involved in the process. Hence, if gravity and inertia are
alike, then it follow that since anti-inertia looks to be
the case chances are that antigravity exists too.

I had no idea this idea was seriously entertained.  AFAIK, "anti-
matter" is just ordinary matter with a reversed choice of quantum
numbers, leading it to go "boom" when it meets equivalent matter.

If anti-matter was not strictly gravitationally equivalent to
equivalent matter, wouldn't this pose some problems for mass-energy
conservation upon an annihilation reaction?  Or would  the adjustment
go in up front, before annilhilation -- so that anti hydrogen would
have a different mass energy than hydrogen, for example?

I thought _negative_ mass energy was needed to mess with gravitational
equivalence.  Unlike anti-matter, when an equivalent quantity of
negative mass energy met positive mass energy, it would not go "boom",
but "poof".  No?

Antimatter is really only special because of star trek.

There isn't even remotely a serious expectation that it falls upwards
or any bullshit like that. Though it is still important to test, which
makes me mad that NASA refuses to fly the experiment that would test
just that to the ISS. God forbid it does some science that a 6 yearold
couldn't think up.

Anti-matter could fall upwards and the kinematics still wouldn't give
a sh.t. There is still that factor of 10^38 or so separating E&M and
gravitation.

Though it would act as a huge violator of the EP since anti-matter and
matter have the same sign on mass. A coupling between gravitation and
some random quantum number would be pretty out there.

That's something like I was getting at.   If anti-matter fell
differently,  then the EP is either broken, or else the mass-energy of
anti-hydrogen is different from that of hydrogen.

So what would we expect if negative (exotic?) mass (not positive mass
anti-matter) met ordinary mass?  Perhaps not a bang, but a whimper.

No, anti-matter is exactly why Professor Roberts said where all the
constituent electric charges have the exact opposite polarities as
ordinary matter.

The mass of anti-matter is still positive.

The physicists have claimed to have produced positrons (anti-
electrons) and anti-protons but, as far as I know, have not the anti-
atom.

Anti-matter is no the negative mass density that Einstein the nitwit,
the plagiarist, and the liar pulled out of his *ss from where Poisson
early resisted in doing so.

So far, there is not even any serious conjecture of what an object
with a negative mass look like, behave like, or even feel like.  Let
alone observed one.  <shrug>

Ignorant poseur. They've been produced for several years
now. Trapping them when they are still relatively high
kinetic energy is the problem.

That is one of the constraints on a SENSIBLE model in which matter and
antimatter behave differently.

For instance, the usual tensor gravity of GR cannot possibly do this,
nor does the standard model, so any model in which they behave
differently under gravity must necessarily go beyond GR and the standard
model. The most plausible extensions involve scalar and vector Bosons
such that the latter couple differently to quarks and antiquarks (just
as the [vector] photon couples differently to them). The scalar Boson is
needed to regularize the vector theory and to prevent the model from
being trivially refuted by ordinary observations of gravity (such as you
mention). So the sum of all 3 (scalar, vector, and tensor) Bosons give
the gravity we all know for matter, but the vector portion changes sign
for antimatter; thus an antihydrogen atom could in principle fall
differently from its normal counterpart.

> Or would  the adjustment

In the type of model discussed above, the mass of antihydrogen is
unaffected. In this type of extension to the standard model + tensor
gravity, Mach's principle does NOT determine masses (bare masses are
intrinsic free parameters of the theory, and the dynamics gives masses
for bound states of bare particles).

> I thought _negative_ mass energy was needed to mess with gravitational

In GR, there is no way to "mess with gravitational equivalence". In the
above models, such equivalence is only approximate.

It depends on more than just "negative energy"....

This depends on the model. In the above model, no, because the coupling
to photons is unchanged -- the new vector and scalar bosons do not
couple to photons at all.

Yes. Actually not many physicists think there will be any measurable
difference, even for much better resolutions than our expected 1% (in
g_bar - g). But this is the sort of thing that should be checked --
after all, that's what science is.

Except that the above model that you described was a SENSIBLE

NON-sensible theory.  ;-)

Not that it really matters, though. If you start from nonsense
assumptions, there's nothing that you can't derive. After all,
"false implies true".

Mesons fall up and down at the same. The matter quark falls down while

finally found some time for a reply.
Actually you might have seen one of my postings on another idea but
since no one brought it up again here goes.
Remember that for example 1 pound of anything dose not have much
gravity so if its gravity was repulsive it might just be swamped out
by all its mass.After all if its tiny gravity were repulsive against
earths gravity then you would notice that 1 pound of antimatter still
weight 1 pound but because its tiny gravity is repulsive you end up
requiring a few more atoms more to make up the same pound meaning its
inertia would be more than a regular pound of normal mass.You get some
really interesting predictions when we change the mass amounts because
if you were to have an entire planet the same size as ours approach
our planet it would become gravitationally invisible and would only
gravitate by whatever the differences are.If for example the
alternative planet were to have an extra pound of weight then the two
planets would gravitate towards each other by only that 1 extra pound.
Its an interesting hypothesis because of the way you end up with at
least one way of being able to explain why our universe is
predominantly matter and yet you also need the 2 types of matter to be
in exactly equal amounts before it will work.
After that the hypothesis get to go into even wilder speculations.

Hypothetical test for this hypothesis.
1 Equal amounts of matter and antimatter will not gravitate towards
each other such as if you had two 1 mg samples in space they would not
gravitate towards each other no mater how much time.
2 Samples of antimatter and matter on a space station in orbit would
allow the two samples to drift into different orbits with the
antimatter sample going into the higher orbit.Larger samples giving
larger differences.
Good luck trying to do a reduction to practice on this one.

Dale
finally found some time for a reply.When looking for percentages of
differences there is one more possibility.
Actually you might have seen one of my postings on this some time ago
but
since no one brought it up again here goes.
A big possibility not mentioned here is based on the idea that
because mass doesn't actually have a lot of gravity associated with
it then even if repulsive it might not be that easily noticed.
For example 1 Kg of anything dose not have much gravity so any
hypothetical repulsion from that much mass could be much less than
the earths gravity on the positive energy that makes up the
antimatter
sample.1 Kg of antimatter would still weigh 1 Kg on a spring scale so
should appear to weight the same but if this hypothesis were right it
would still actually require more mass to balance out the tiny
repulsion of the antimatters repulsive gravity.
So its actual inertial mass could be slightly more than a regular Kg
if this hypothesis were right and leading to some equivalence
principle violations.
You get some really interesting predictions when we change the mass
amounts because if you were to instead have an entire planet the same
size and mass as ours approach our planet it would become
gravitationally invisible and would only gravitate by whatever the
mass differences actually are.If for example the alternative planet
were to have an extra pound of weight then the two planets would
gravitate towards each other by only that 1 extra pound.
Its an interesting hypothesis because of the way you end up with at
least one hypothesis to explain why our universe is predominantly
matter and because you need the 2 types of matter to be in exactly
equal amounts before it will work it fits with how antimatter was
required to be in equal amounts in the big bang.
After that the hypothesis gets to go into even wilder speculations.
Hypothetical test for this hypothesis.
1 Equal amounts of matter and antimatter will not gravitate towards
each other such as if you had two 1 mg samples in space they would
not gravitate towards each other no mater how much time.

The electromagnetic forces on those trapped positrons exceed the
gravitational force on them by a truly enormous factor. This is no test
of the equivalence principle at all. Neither are the antiprotons
circulating around the Tevatron for ~24 hours.

    Your claim is essentially equivalent to claiming that
    chairs do not fall under gravity, because when placed
    on the floor they don't fall. That, too, is because
    the electromagnetic forces on the chair exceed the
    gravitational forces by many orders of magnitude. When
    those EM forces are removed or canceled, chairs quite
    clearly do fall; but nobody knows what actually happens
    for antimatter, because to date nobody has been able to
    remove or cancel those comparatively enormous EM forces.

To have any hope of measuring the force of gravity on antimatter, or of
testing the equivalence principle for antimatter, one must cancel the
electromagnetic forces to extremely high accuracy. The best way of doing
that reliably is to form a neutral anti-atom. For antiprotons and
positrons that is quite difficult....

Thanks for posting the link to this article.  The Aether Physics Model
predicts all antimatter is gravitationally repulsive to normal
matter.  Can you post a link to your paper?  I would like to read it.

It is easy to induce that antimatter and matter are gravitationally
repulsive.  Two photons can combine to produce a positron-electron
pair.  The positron and electron are massive particles, having the
same mass but opposite spin.  The positron and electron must have
transformed from the two photons.  This means the photon contains both
left and right spin mass, but only half of an electron mass worth of
each.  The photon has zero net mass, which means that the two masses
must cancel each other out, which means they must be gravitationally
repulsive.

Modern theory cannot accept a photon being composed of two opposite
spinning masses because they don't have the structure necessary for
the two spins to coexist.  To quantify such a structure requires an
Aether.

Since GR predicts antimatter is gravitationally attracted to matter,
this could be the physical experiment that changes everything.  Let's
hope they can get the funding.

Greysky  If gravity is a "push" down force than up is the wrong
direction. Reality is gravity is not used as a balancing force. It is
only a compression inward force. As such it can create and evolve all
that is. As such it is the time clock of the universe. If time was
balanced there would be no time. etc   Bert PS it is better thinking the
Earth came up to the apple than the apple fell into space. Both are not
reality but one is better than the other   Go figure  Bert

Yes, an antimatter apple falls up in a world
made mainly of ordinary matter. An antimatter
apple falls down in an anti-world, and an apple
made of ordinary matter falls up in that anti-world.

The term "anti-matter" certainly does get its share of exposure, and in
almost all cases the word "theory" can be found lurking in the neighborhood.
It is an established fact that one thing matter and anti-matter excel at is
mutual annihilation.  Based on that astute observation, the Universe should
be entirely composed of either one, or the other. One theory bandied about
has it that, after the BB, matter and anti-matter were formed in almost
equal amounts, with matter running a slight 1 in a million particle
favorite.  In other words, for every 1,000,000 particles of matter and
anti-matter that met in a dance of cataclysmic death, one lonely particle of
matter survived. When the orgy of destruction was over, matter had won out
by the slimmest of margins and anti-matter was relegated to the bin of
history.  The surviving matter is the stuff we are made of.
Scientists claim that anti-matter has been created in Super Colliders, but
only lasted a fraction of a milli seconds before meeting the knell of death
by the hand of its contemporary matter compatriots.  So, the question is:
does anti-matter exist in our present Universe ?  Do we really have to worry
about, or even consider the proverbial anti-matter apple hitting us in the
butt on its way up ??

There are some cosmic events of such phenomenal force that perhaps matter /
anti-matter interaction may be the only logical explanation. But if that is
a consideration, where do the anti-matter particles come from, what process
creates them.  Could there be a third kind of "Neutral Matter" which can
intermingle with the two arch enemies and allow the anti-matter particle to
evolve to maturity before venturing into hostile territory. Could that
"Neutral Matter" actually be the ashes of the original post Big Bang
slugfest of destruction between matter and anti-matter and over the eons
evolved into the scientific Holy Grail of  "Dark Matter" ?

Mesons are a matter and anti matter quark mix. This is hybrid matter
anti matter.

Uh, Greysky...

Consider that photons, which are their own antiparticle, fall
"down" in a gravitational field. This has been known for nearly
a century.

If matter falls down in a gravitational field, and antimatter
falls up in a gravitational field, shouldn't photons go right
through a gravitational field with no deviation?

The hope is that antimatter may fall "differently" in a
gravitational field. Nobody except a crackpot thinks that
antimatter will fall up.

...in 1932, by Carl Anderson.

http://livefromcern.web.cern.ch/livefromcern/antimatter/history/AM-history01-a.html

The cloud chamber used a magnetic field to separate particles by the
charge-mass ratio.  If both the charge and the mass of the positron
were the exact opposite of that of the electron, then the charge-mass
ratios would be the same, and the particles would be
indistinguishable.

The fact that the electron and the positron curve in opposite
directions is proof that only one of the two parameters (mass or
charge) is the opposite.

Separate experiments with electric fields (which distinguish particles
by charge alone) confirm that the mass of the positron is the same as
that of the electron, while the charges are exactly the opposite of
each other.

I thought of that, but the obvious response is that inertial
mass is not necessarily the same as gravitational mass. The
direction of turn in a bubble chamber depends on inertial mass.

Oh man,
C,mon everyone!
Just make the dang particles spin backwards to
direction of travel.
They will curve up like a freaking golf ball
even in vacuum, because the stuff you can't see
nor detect in that vacuum is still effecting them

Some more sillyness,
Or some real fun for anyone ableto play in an accelerator...

A 0 spin object pushed in a clockwise circular path motion
will turn into counterclockwise spin.
A 0 spin object pushed in counterclockwise circular path motion
will turn into clockwise spin.

Magnetic fields still have drag that can cause spin...
It's all very simple mechanics.
so backspin it and make it negate gravity until the magnetic
field starts spinning it in the opposite motion of the circular path.
:)
wheels within wheels.
gears all over the place,
and yet nobody will play with them as such!
:)
Is mechanical motion that hard to understand?
If you can't make it do such, there is something
else physically and mechanically in the way.
find it and report it..
Science will march on...
The lever and fulcrum and gears etc always follow
the law of mechanics.
anything made of mass will do the same.

  Clockwise and Counter clockwise with respect to what, spacey?

Oops..
In reality, it does not matter as long as one is the opposite
of the other for such, and the speed is great enough.
In the example given I was thinking of an accelerator and that would
mean WRT the ground of course.
