Gravity bends more than just space. It bends time. The early results from Gravity Probe B, one of NASA’s most complicated satellites, confirmed ‘to a precision of better than 1 per cent’ the assertion Einstein made 90 years ago - that a massive object such as the Earth does indeed distort the fabric of space and time. This explains why GPS satellites must correct for time distortion: it passes more quickly in orbit than on the Earth.
