Mass warps space and time, just as Albert Einstein said it would, confirms data from a NASA satellite launched to test two of the great physicist's predictions. One of these effects is called the ...

For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct. April 14, at the ...

A ‘senior review’ of NASA’s astrophysics missions has concluded that a satellite that is trying to measure gravitational effects predicted by Einstein’s theory of general relativity should receive no ...

A preliminary analysis of data from the Gravity Probe B satellite has confirmed that the Earth's mass distorts the fabric of space and time as predicted by Einstein's theory of general relativity.

Jury’s still out on the “frame-dragging” business. That’s according to this news report from an academic conference yesterday: After half a century, seven cancellations and $700 million, a mission to ...

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...

It has taken almost 50 years to conceive and build and has cost $600 million, but now NASA’s Gravity Probe B spacecraft could be upstaged by telescopes on the ground. The craft is designed to ...
