Einstein was right: space and time bend
Ninety years after he expounded his famous theory, a $700m Nasa probe has proved that the universe behaves as he said. Now the race is on to show that the other half of relativity also works
Under his name in the Oxford English Dictionary is the simple definition: genius. Yet for decades physicists have been asking the question: did Albert Einstein get it wrong? After half a century, seven cancellations and $700m, a mission to test his theory about the universe has finally confirmed that the man was a mastermind – or at least half proved it.
The early results from Gravity Probe B, one of Nasa’s most complicated satellites, confirmed yesterday ‘to a precision of better than 1 per cent’ the assertion Einstein made 90 years ago – that an object such as the Earth does indeed distort the fabric of space and time.
The other, ‘frame-dragging’, stated that as the world spins it drags the fabric of the universe behind it.
