Satellite To Test Relatively 33
dude_from_munich writes "Einstein proposed in 1916 that space and time form a structure that can be curved by the presence of a body. Scientists are finally planning to put Einstein's theory of relativity to test after a project delay of 44 years."

Which means performing the test was meaningless.

First they double check and triple check and quadruple check the results.
If those results are consistantly confirmed, then we celebrate.
We *know* that there must be some theory beyond Relativity - a theory to explain and predict the things we cannot currently explain or predict. The "problem" is that Relativity is "too perfect". Relativity has been like a perfectly smooth glass wall - it gives absolutely no crack or crevice or clue to climb beyond it. What

This [slashdot.org] is just one example, but I'm sure many more can be found without launching the probe...

Albert Einstein was a great scientist who lived long ago. He had two theories, the General Theory of Relatively and the Special Theory of Relatively. Later on he married his cousin.
Of course GTR has been confirmed many times (Score:4, Insightful)
It's a popular Senior or Graduate physics exercise to design experiments demonstrating GTR -- and a somewhat more ambitious exercise to perform them. This one is notably primarily for being bloody expensive and having blown it's schedule by such a honking big margin.

Of course, the GPS system is not anywhere near the first proof of this or many other relativistic phenomena; atomic clocks on board jetliners can test whether gravity affects the speed of a clock (it does) and

How to Build a Cloud Chamber [cornell.edu]
You can probably scavenge common felt and tape and a slide projector etc for free. You can buy pure (not 70%) isopropyl alcohol for about $7.60 [web-tronics.com], and Dry Ice [dryicedirectory.com] for probably $20 or less. I can pick up dry ice locally for $10. The issue with dry ice is that it will only last a day or so unless you get a huge block. I had a $40 block last 3 or 4 days.
Dry Ice is a real blast for parties, but at -109.3F / -78.5C you freez
