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 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.
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
space-time 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.” 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 space-time) and the frame dragging effect is
the amount of wobble caused by the spin of the Earth (the twist in space-time).
Both values are in precise accord with Einstein’s predictions.
Note: Our visitors have explored the space-time vortex that
exists around Earth that is duplicated and magnified elsewhere in the
cosmos. This concept may explain extraterrestrial space travel from
distant planets to Earth in a relatively short time.
