Kelley Blue Book For road-trippers and commuters, here are 16 cars with zero gravity seats that can really save your butt Thank the astronauts for these seats ...

The Tesla Model X has some serious competition -- the Lucid Gravity has been revealed, and it has a lot to offer. But how do they compare?

After 45 years of development and delays, NASA's Gravity Probe B satellite was launched into orbit Tuesday morning to test a key prediction of Albert Einstein's general theory of relativity.

NASA's Gravity Probe B mission has blasted off successfully and has begun a 44-day period in which it gears up to test Einstein's theory of gravity with exquisite precision. The three-tonne probe ...

Gravity Probe B was put in space to confirm two important consequences stemming from Einstein's Theory of General Relativity - his description of gravity.

But Gravity Probe B measured them both. The results will be published in Physical Review Letters. The spacecraft orbited Earth for 17 months carrying four pingpong-ball–sized gyroscopes.

The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would use gravity fields to precisely map the interiors and compositions of the outer planets and other celestial bodies.

A NASA probe orbiting Earth has confirmed two key predictions of Albert Einstein's general theory of relativity, which describes how gravity causes masses to warp space-time around them.

The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would use gravity fields to precisely map the interiors and compositions of exoplanets and other celestial bodies.

A new probe in development known as GIRO represents a low-cost step toward unlocking the secrets of exoplanets, all through the invisible pull of gravity.
