Title: Frame dragging test
Post by: blobrana on April 19, 2004, 05:22:54 PM

 A satellite that will put Albert Einstein's Theory of Relativity to the test is about to lift off at 1801 GMT today...

Einstein argued that the space-time continuum was twisted and distorted by the spinning of massive objects, an effect known as frame dragging.


"We've seen two of the three aspects of warped space-time. We've seen the warping of space and the warping of time. We have never seen, in any clean way, the dragging of space into motion"

[Haha! This will show them all...]

BTW, has anyone got pictures of the antarctic solar eclipse that happened today? :-)

The launch has been delayed to 1657 GMT on Tuesday.

Oh well, heres hoping...

As a side note the `hold` was called approximately three minutes before lift off yesterday, after it was determined there was insufficient time to confirm, before launch, the correct wind profile had been loaded aboard the Delta II based on the data from the final weather balloon.

Whoops....(something quite funny there)

For those not in the  `know` the frame-dragging effect was first derived from the theory of general relativity in 1918 by the Austrian physicists Joseph Lense and Hans Thirring. Other names for this effect are gravitomagnetism and the Lense-Thirring effect.
I expect that everybody will be very happy when we do confirm this prediction, er, otherwise we may all just pop-out of existence ...
