from the link you posted concerning the gravity probe which claims to prove that einstein was correct. http://www.nasa.gov/mission_pages/gpb/gpb_results.html
it is impossible for a anything to point at a anything forever
when in an earth orbit because everything beyond the earth is
I see this as a cheap attempt to validate a lie.
the attempt is probably founded via a education that included
a lie as its foundation.
thus more lies must be invented to cover up the paid for lies
acquired in the education process.
GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them.
1: a polar orbit.
there is no such thing as a orbit around the earth that never
changes its orbital path.
there will always be tugs on any satellite orbiting the earth
by all of the thousands of other satellites orbiting the earth as it orbits the earth which would pull the satellite out of its intended , planned orbit.
these would be tiny almost unnoticeable orbital changes as have been proposed to verify einstein theory.
2: also the earths axis fluctuates which will cause a corresponding change in all satellites orbits around the earth.
some earthquakes have caused the earths axis to change in a single moment.
3: just because nasa says something is true does not mean that
what is said is true.
4: a gyroscope will maintain its spin if encased inside a orbiting satellite , this spin will maintain its path as the satellite orbits around the earth.
however a gyroscope cannot cause a satellite to maintain its orbital altitude , gravity from the earth will still cause the satellite to accelerate towards the earth.
the angular velocity of the satellite is what causes the satellite to maintain its orbital altitude.
minute fluctuations in the earths gravity field causes a satellite to move into both a higher and lower orbit as a satellite orbits the earth.
these fluctuations in orbital altitude are minute but can be measured.
the velocity of a satellite that has moved into a lower earth orbit has increased thereby reducing its orbital time by a fraction that can be measured.
the velocity of a satellite that has moved into a higher earth orbit has decreased thereby increasing its orbital time by a fraction that can be measured.
there are many minute orbital changes that a satellite undergoes that can affect measurements taken from instruments onboard a satellite.
why they decided that these measurements prove any theory
concerning the proposed space time or any of the other fantasy theories is beyond logic.
5: one more thing that may not have been considered is the electrical charge of the satellite as it orbits within the earths magnetic field.
a spinning gyroscope has both a gravitational field and a magnetic field due to its charge ,
as internal electrical charges build up in the gyroscope
due to spacecraft charging the gyroscopes magnetic field strength increases , the magnetic field of the spinning gyroscope will then try to align itself with the ever changing magnetic field of the earth which will cause minute spin changes.If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit.
as pointed out above , I dont think space and time fantasy have anything to do with it , it is the real instances of events and forces that actually occur that are the reasons that the gyroscopes do not point in the same direction forever.
personally I wont accept that a satellite orbiting the earth could possibly prove any of einsteins theories.
the gyroscope inside the GP-B satellite is a sphere of fused quartz. http://www.resonancepub.com/gravity.htm
note : that quartz will deform when a electrical current is passed through it.
quartz is a non conductive material , however it has a small
charge , it is a piezoelectric which means that when subjected to pressures it generates electricity and vice-versa
the quartz sphere is rotated up to 170 Hz by a gas , however it
is suspended by two electrical charges placed on the two bowl
shaped electrodes pictured above.
spacecraft charging can alter these suspending charges so that the sphere would become closer to one side than the other generating a compression to the sphere as it moves from one side to the other that could deform the sphere during spacecraft charging events.
retrieval of the sphere and inspection will probably show
that the sphere has contacted the electrodes several times.
which would cause minute changes in its spin.
