>> Albert Einstein didn't think it could be done. The scientist was convinced that we'd never be able to measure gravitational waves, ripples in the fabric of space-time caused when a mass accelerates. And that can as simple as an ice skater pirouetting or a pair of black holes rotating around each other.

Einstein predicted them a century ago, but three American scientists did detect them, and their discovery has now won them the Noble Prize in Physics. Rainer Weiss, Kip Thorne, and Barry Barish played leading roles in the Laser Interferometer Gravitational-Wave Observatory or LIGO experiment. Reuters Ben Hirschler explains.>> Einstein predicted that gravitational waves existed 100 years ago.

But he doubted that whether they'd ever be able to measure them because by the time they reach earth they're tiny, and you need to have a super precise machine to measure them. We're talking about vibrations which are smaller than the thousandths of the size of a nuclear civil atom.

>> In September 2015, the universe's gravitational waves were observed for the first time. It took 1.3 billion years for them to arrive at the LIGO detector on Earth. All sorts of electromagnetic radiation and particles, cosmic rays and neutrinos have been used to explore the universe. But gravitational waves are direct testimony to disruptions in space-time itself.

>> With gravitational waves, you've got a whole new way of measuring what's going on in the universe, and it gives an insight into non-visible objects like black holes.>> This is completely new and opens up unseen worlds. Scientists say a wealth of discoveries awaits those who succeed in capturing the waves and interpreting their message.
