Theos-Talk Archives (October 2005 Message tt00085)

Hi folks,

The following article covering the latest findings in physics seems to be the 
beginning of the final proof of theosophy, as predicted by HPB to come around 
the turn of the 20th and 21st centuries. These findings -- based on 
relativity and quantum theories in conjunction with the elegant mathematicsof 
Superstring/M-brane theory and the ABC model linking consciousness, mind, brain, body, 
etc. with mass-energy or matter through fractally involved holographic fields 
within fields within fields in seven hyperspace dimensions -- will ultimately 
eliminate the last objection that theosophy is not scientific and does not 
teach the true nature of all reality... From the zero-point through the seven 
fold inner fields, to the vastness of phenomenal space... That we each, as the 
microcosm of the macrocosm, can experience directly in its entirety. 

The last aspect of reality that science has to accept to make it entirely 
consistent with theosophy is; That subjective consciousness (awarenesss-will) is 
the inherent nature of the ubiquitous zero-point of Absolute Space itself and 
is always separate from and beyond objective space and time... Yet, 
simultaneously arising with them at the primal beginning, along with the mind and memory 
fields that all originate in the angular momentum of the g-force or "spinegy' 
surounding .

The current controversies between "intelligent design" and "scientific 
evolution" is sign that the entire world is beginning to pay attention to these new 
discoveries. 

Best wishes,

A tool to measure what happens in empty space

Physicists have devised a new tool to track what goes on in what we normally 
call empty space.

An “empty” space is never truly empty, physicists believe, even if every 
atom and particle in it has been removed. This is because particles will continue 
to appear out of nowhere, then vanish.

In the new research, physicists report having measured this activity using a 
cloud of atoms that merge to effectively become one giant atom. This bizarre 
substance, called a Bose-Einstein condensate, was invented a decade ago buthas 
found little practical use since then.

The new findings, researchers say, mark the first time a Bose-Einstein conden 
been used to study anything besides its own properties. It was employed to 
investigate something perhaps even stranger: the so-called virtual particles 
that appear and disappear in the void.

Engineers must take virtual particles into account as they design ever-tinier 
machines and robots, a growing industry. On small scales, virtual particles 
create unpredictable forces that can throw off these devices.

In studying virtual particles, the researchers probed a phenomenon that seems 
to violate a physical law recognized more than two centuries ago: the law of 
conservation of energy.

The law says energy can neither be created nor destroyed. It’s alsotrue of 
any object, because objects have mass, and mass is convertible to energy. 
Einstein showed this.

Virtual particles get around this law thanks to a subatomic phenomenon called 
the uncertainty principle. Understanding the principle, as well as 
Bose-Einstein condensates, requires some explanation of the nature of subatomic 
particles.

Particles and waves

Scientists consider subatomic particles as things with two seemingly 
contradictory natures: they are both particles and waves. This is because they act 
like one or the other depending on the experiment one does. 

One can shoot them into a target like tiny bullets, in which case they act 
like particles. 

But they also move like waves: for instance, they create interference 
patterns. These are patterns similar to those that appear when one drops two pebbles 
in a pond. Complex ripple patterns will appear where the two sets of circles, 
each expanding outward, overlap.

Physicists have found that subatomic particles’ wave nature makes it 
impossible for the particles to have both a precisely defined location and speed. This 
ultimately lets them briefly appear out of nowhere. 

The effect is due to certain oddities of particle-waves.

One of these quirks is that with particle-waves, unlike with water waves, 
there is no physical thing that actually “waves” or oscillates. With 
particle-waves, what oscillates is the probability that the associated particle will be 
found in one place or another when an experimenter looks for it. 

Physicists have no idea why any of this is so, or what it means. They’ve just 
found that it happens to work this way.
Another unusual property of a particle-wave is that, unlike a water wave, it’
s not a long series of ripples following each other like a parade. It’s 
instead a group of just a few ripples bunched together, called a “wave packet.” 

Mathematically, the only way to represent a wave packet is as a composite of 
many sets of waves, lined up so that their peaks and troughs cancel out 
everywhere except in the area of the wave packet. The resulting packet consists of 
one bigger central wave, with smaller waves in front of it and behind it, dying 
down with increasing distance from the central wave. 

Thus the wave packet has no precise location; it’s a little spread out. By 
adding more overlapping waves, one can reduce this spread, though never 
eliminate it completely.

Each of the many waves that go into a wave packet has a slightly different 
speed. Thus the wave packet itself has a range of speeds, which of course makes 
no sense if you think of it as a particle. But the wave nature of particlesis 
like this. 

Uncertainties

So not only does it have an imprecisely defined location, it also has an 
imprecisely defined speed. In fact, more precisely you define its location,the 
less precisely you define its speed—because you’re adding more waves. The more 
precisely you define its speed, the less precisely you define its location—
because you’re subtracting waves and increasing the spread.

The idea that there’s no such thing as empty space stems from this finding 
that a particle can’t have both an exact speed and location. A point of “empty” 
space is mathematically identical to a weightless particle with a speed of 
zero and a perfectly defined location, that being the point itself. This isn’t 
allowed.

Therefore, physicists postulate that empty space is actually full of 
subatomic particles that flash in and out of existence. 

This doesn’t violate energy conservation because it turns out that the 
uncertainty in speed and position is translatable, mathematically, into 
uncertainties in energy and time. If a particle is short-lived enough, its energy can be 
so “fuzzy” that whoever or whatever enforces the conservation of energy law can
’t detect a violation.

Unfortunately, the fuzziness of virtual particles also makes them impossible 
to detect by any measuring instruments. Not directly, anyway. But 
circumstantial evidence of their existence is obtainable.

One way to find this evidence is through an effect called the Casimir-Polder 
force. If an atom is very close to a flat surface, some particle-waves can’t 
fit between the atom and the surface. Waves, in particular, need space. 

This means there will be a few less virtual particles to one side of the atom 
than the other. 
On the side with more virtual particles, it will “feel” a slight force 
pushing it toward the plate. This is because the virtual particles will be 
occasionally banging into the atom from that side, more often than from theother 
side. 

A related effect occurs when two flat plates are close enough together, in 
which case the plates will be attracted to each other.

Physicists have trouble measuring these forces because they are so slight. 
But Eric Cornell and his colleagues at the University of Colorado in Boulder, 
Colo. reported last month they were able to measure the Casimir-Polder force 
using a Bose-Einstein condensate. The experiment, they added, may lead to new, 
more sensitive measurements of these small-range effects.

Bose-Einstein condensates

A Bose-Einstein condensate, like the Casmir-Polder force, exists thanks to 
strange laws of quantum mechanics, the physics of the very small.

Normally, the atoms in a gas are scattered, bouncing around like ping-pong 
balls. But if the gas is cooled, the atoms slow down. Cooling it more makes 
their speeds approach zero. But this is a precisely defined number. Since the 
speed becomes better defined, each atom’s location must become lessdefined. In 
technical terms, each atom’s wave packet—the zone in which the particle might 
be found—grows.

Make the gas colder and colder, and each wave packet starts to overlap with 
neighboring ones, growing until it envelops all the rest. Thus, all the wave 
packets overlap. If all the atoms are identical, the wave packets, and thusthe 
atoms, can merge and become indistinguishable. They are all in the same place, 
have the same speed, and so on. They are like one atom. 

This is a Bose-Einstein condensate.

Because a condensate acts like one atom, it feels the Casimir-Polder force. 
But since it’s much easier to see than an atom, it makes that forceeasier to 
measure, said John Obrecht, a member of the University of Colorado team.

As they described a paper published in the Sept. 15 issue of the research 
journal Physical Review A, Cornell and colleagues created a Bose-Einstein 
condensate shaped like a thin cigar. Using a magnetic field, they made it float a few 
thousandths of a millimeter from a flat plate made of silica. They then set 
it gently oscillating.

Because the Casimir-Polder force tugged more strongly on the side of the 
cloud closer to the plate than on the further side, it disrupted the normal 
oscillations slightly. By comparing the oscillations with and without the nearby 
plate present, Cornell’s team estimated how strongly the force was acting.

This way they tallied the force at a distance of 5 thousandths of a 
millimeter, “significantly farther than has been previously achieved,” the team wrote.

The researchers said the work could aid in the design of 
microelectromechanical systems (MEMS), tiny electronic devices built at this scale or smaller, and 
used in industries such as medicine, automobiles and electronics.

“Tremendous experimental progress in both ultracold atomic systems and 
microelectromechanical systems (MEMS’s), has pushed both fields towards precise work 
very close to surfaces—regimes where Casimir-type effects become important,” 
Cornell and colleagues wrote.

Maarten DeKievit of the University of Heidelberg in Germany said Cornell’s 
approach is a good start towards getting more precise measurements of these 
forces, but needs more work to become useful. 
This is because the cloud in the experiment had just one shape, he said, but 
physicists need information to help them predict what would happen with any 
shape. The effects can be so complicated, he added, that results with one shape 
don’t say much.

“It’s a very nice experiment,” he said. “What you could dream of is if that 
they could change the form of the condensate” to get a range of precise 
shapes, he added. Then they could measure the force “as a function of shape.”
