Albert Einstein Proved Correct Once Again

[UM-Bot]

An experiment using two orbiting satellites has proved that as the Earth turns it drags space and time around itself, like a spinning top in treacle. The result is yet another vindication of Albert Einstein’s genius. His theory of general relativity, published in 1916, said that material objects warped space and time around them.

In 1918, Joseph Lense and Hans Thirring used Einstein’s equations to predict that a rotating body will twist space-time enough to disturb a small object orbiting it.

its things like this that lead me to believe we will learn instantanious travel before we learn light speed travel .

I knew he was right all along.

NASA sent a satelite up a while back, that had 2 pefectly shaped balls in it to see if space-time curved in space and spun the balls or something like that. Im not sure about the details. Anybody know if that expermint went through, or anything about it?

Yes and if there were any hints of time anomolies from reception of the Mars probes????

A new mission with a low orbital eccentricity and a favorable orbital inclination would allow decorrelating J2 and J3 from the higher-degree harmonic coefficients of the gravity field. Such an orbit will therefore better extract time-variable gravity and improve our knowledge of the atmosphere and interior of Mars. Furthermore, an orbiter reaching a low altitude at pericenter (below 200 km) will improve our knowledge of the local structure of the crust and lithosphere, by way of the study of static gravity anomalies. On the other hand the orbiter can be used to determine the rotation variations of Mars.

So if planets don't rotate... like the moon... what would the time ratio effect be of it???

A/s World Turns it Drags Time and Space

An international team of NASA and university researchers has dramatically improved the accuracy of the first direct evidence that the Earth drags space and time around itself as it rotates. The measurements used the latest gravity models obtained from NASA's GRACE mission."

The Moon is too far away to be significantly affected by frame-dragging due to the Earth's spin, so it fell to artificial satellites LAGEOS and LAGEOS 2 (for Laser Geodynamics Satellites) to detect the Lense-Thirring effect. http://cerncourier.com/cws/article/cern/29218

The Moon does rotate, it's "tidally locked" with the Earth, meaning the time it takes for it to rotate around its axis one full time is equal to the time it takes to make one full revolution around the Earth; resulting in only one side of the Moon ever facing us.

Not exactly sure of what your question is, though.

basically would all planets have different Space times??? that relate to their gravity???

Would radio frequencies... communication be affected... an how... ??? ...and if not why???

It appears though that their studies can only guarantee about 10% accuracy

and that the theory didn't appear to work using Mars as an example...

and strangely little else has been published since that I can see...

Abstract

We show here that the recent claim of a test of the Lense-Thirring effect with an error of 0.5% using the Mars Global Surveyor is misleading and the quoted error is incorrect by a factor of at least ten thousand. Indeed, the simple error analysis of [1] neglects the role of some important systematic errors affecting the out-of-plane acceleration. The preliminary error analysis presented here shows that even an optimistic uncertainty for this measurement is at the level of, at least, ~ 3026% to ~ 4811%, i.e., even an optimistic uncertainty is about 30 to 48 times the Lense-Thirring effect. In other words by including only some systematic errors we obtained an uncertainty almost ten thousand times larger than the claimed 0.5% error.

Yes. General relativity tells us that massive objects cause spacetime to curve, and the greater the distortion of space time the slower time passes.

They would be, it's an effect known as gravitational redshift. When a photon travels through a region of space with an increased gravitational field it loses energy, but photons can not decrease in speed (speed of light is constant), so instead their frequency is decreased and shifted towards the red end of the spectrum.

I still don't understand how we can say that it warps space and "time". I thought we were still unsure as to what time is exactly. I always looked at it as a man made concept to determine "how long" it takes for movements to happen. Isn't just movement time?

Sure, if space is warped, it could change how quickly or how slowly something moves, but doesn't that just affect physical movement itself and not time, like how bullets will move slower through water, hence our CONCEPT(Man made) of time has to be changed when space is warped into a different form that we experience it on Earth.

And if the above is correct, isn't it just warping "space" and not "spacetime".
