NASA confirma que existe un Vortex Espacio-Tiempo que rodea la Tierra.
Los últimos hallazgos científicos, muestran que la gravedad interactúa con
el espacio-tiempo, tal y como Albert Einstein sugería. La cuesti toda la lógica de la teoría
de œsuperwave formulada por astrofísicos de la talla del Dr. Paul
Laviolette, en la línea de la Radiofrecuencia Cuántica Diferencial. La
interacción de la Gravedad con las ondas fase y las líneas del Tiempo,
trazaría escenarios en los que a nivel subcuántico, se modificaría
el
espacio-tiempo.
De acuerdo con el modelo propuesto esta vez por Francis Everitt,
Investigador principal de la misión Gravity Probe B, de la Universidad de
Stanford, el espacio-tiempo que rodea la Tierra está distorsionado tal y
como Albert Einstein predijo.
La NASA, ha publicado un draft en el que resume los resultados mas
relevantes de la misión, en su web de divulgación científica.
De acuerdo con los resultados de esta misión, estamos ante el comienzo de un
giro de 180º en la concepción de los modelos de la física. Resulta
interesante comprobar cómo poco a poco la NASA, va confirmando las teorías
que anteriormente cuestionaba e incluso consideraba ridículas. Ante este
hallazgo, debemos recordar a todos los científicos a los que se ha
ridiculizado, censurado e incluso a riesgo de perder sus puestos de trabajo
y su credibilidad.
Tarde o temprano las evidencias salen a la luz, y en esta
ocasión en memoria
de Albert Einstein, cuya formulación ya apuntaba a este interesante hallazgo
El descubrimiento es de gran transcendencia, ya que abre las puertas a una
nueva dimensión de la física, tal y como asegura Clifford Will de la
Universidad de Washington, y en esa línea seremos capaces de entender los
puentes de Einstein-Rossen y otros eventos espacio-tiempo, asegura Will.
Y es que cada vez está más claro: Las Resonancias Schumann son la clave para
entender la Gravedad y no a la inversa. La explicación está en la
Radiofrecuencia Diferencial y no en la física de Partículas.

NASA Announces Results of Epic Space-Time Experiment

May 4, 2011: Einstein was right again. There is a space-time vortex around
Earth, and its shape precisely matches the predictions of
Einstein's theory
of gravity.
Researchers confirmed these points at a press conference today at NASA
headquarters where they announced the long-awaited results of Gravity Probe
B (GP-B).
"The space-time around Earth appears to be distorted just as general
relativity predicts," says Stanford University physicist Francis Everitt,
principal investigator of the Gravity Probe B mission.

"This is an epic result," adds Clifford Will of Washington University in St.
Louis. An expert in Einstein's theories, Will chairs an independent panel of
the National Research Council set up by NASA in 1998 to monitor and review
the results of Gravity Probe B. "One day," he predicts, "this will be
written up in textbooks as one of the classic experiments in the history of
physics."
Time and space, according to Einstein's theories of
relativity, are woven
together, forming a four-dimensional fabric called "space-time. " The mass of
Earth dimples this fabric, much like a heavy person sitting in the middle of
a trampoline. Gravity, says Einstein, is simply the motion of objects
following the curvaceous lines of the dimple.
If Earth were stationary, that would be the end of the story. But Earth is
not stationary. Our planet spins, and the spin should twist the dimple,
slightly, pulling it around into a 4-dimensional swirl. This is what GP-B
went to space in 2004 to check.
The idea behind the experiment is simple:
Put a spinning gyroscope into orbit around the Earth, with the spin axis
pointed toward some distant star as a fixed reference point. Free from
external forces, the gyroscope's axis should continue pointing at the
star--forever. But if space is twisted, the direction of the gyroscope's
axis should drift over time. By noting this
change in direction relative to
the star, the twists of space-time could be measured.
In practice, the experiment is tremendously difficult.

The four gyroscopes in GP-B are the most perfect spheres ever made by humans
These ping pong-sized balls of fused quartz and silicon are 1.5 inches
across and never vary from a perfect sphere by more than 40 atomic layers.
If the gyroscopes weren't so spherical, their spin axes would wobble even
without the effects of relativity.
According to calculations, the twisted space-time around Earth should cause
the axes of the gyros to drift merely 0.041 arcseconds over a year. An
arcsecond is 1/3600th of a degree. To measure this angle reasonably well,
GP-B needed a fantastic precision of 0.0005 arcseconds. It's like measuring
the thickness of a sheet of paper held edge-on 100 miles away.
"GP-B researchers
had to invent whole new technologies to make this possible
" notes Will.
They developed a "drag free" satellite that could brush against the outer
layers of Earth's atmosphere without disturbing the gyros. They figured out
how to keep Earth's magnetic field from penetrating the spacecraft. And they
created a device to measure the spin of a gyro--without touching the gyro.
More information about these technologies may be found in the Science@NASA
story "A Pocket of Near-Perfection. "
Pulling off the experiment was an exceptional challenge. But after a year of
data-taking and nearly five years of analysis, the GP-B scientists appear to
have done it.
"We measured a geodetic precession of 6.600 plus or minus 0.017 arcseconds
and a frame dragging effect of 0.039 plus or minus 0.007 arcseconds," says
Everitt.
For readers who are not experts in relativity: Geodetic precession is the
amount of wobble caused by
the static mass of the Earth (the dimple in
spacetime) and the frame dragging effect is the amount of wobble caused by
the spin of the Earth (the twist in spacetime). Both values are in precise
accord with Einstein's predictions.
"In the opinion of the committee that I chair, this effort was truly heroic.
We were just blown away," says Will.

The results of Gravity Probe B give physicists renewed confidence that the
strange predictions of Einstein's theory are indeed correct, and that these
predictions may be applied elsewhere. The type of spacetime vortex that
exists around Earth is duplicated and magnified elsewhere in the
cosmos--around massive neutron stars, black holes, and active galactic
nuclei.
"If you tried to spin a gyroscope in the severely twisted space-time around
a black
hole," says Will, "it wouldn't just gently precess by a fraction of
a degree. It would wobble crazily and possibly even flip over."
In binary black hole systems--that is, where one black hole orbits another
black hole--the black holes themselves are spinning and thus behave like
gyroscopes. Imagine a system of orbiting, spinning, wobbling, flipping black
holes! That's the sort of thing general relativity predicts and which GP-B
tells us can really be true.
The scientific legacy of GP-B isn't limited to general relativity. The
project also touched the lives of hundreds of young scientists:
"Because it was based at a university many students were able to work on the
project," says Everitt. "More than 86 PhD theses at Stanford plus 14 more at
other Universities were granted to students working on GP-B. Several hundred
undergraduates and 55 high-school students also participated, including
astronaut Sally Ride and
eventual Nobel Laureate Eric Cornell."
NASA funding for Gravity Probe B began in the fall of 1963. That means
Everitt and some colleagues have been planning, promoting, building,
operating, and analyzing data from the experiment for more than 47
years”truly, an epic effort.
What's next?
Everitt recalls some advice given to him by his thesis advisor and Nobel
Laureate Patrick M.S. Blackett: "If you can't think of what physics to do
next, invent some new technology, and it will lead to new physics."
"Well," says Everitt, "we invented 13 new technologies for Gravity Probe B.
Who knows where they will take us?"
This epic might just be getting started, after all¦.
