It is the force which structures the Universe. It creates galaxies, stars and planets. It switches on the nuclear furnaces in stars which bring light and life to the Universe. It can accumulate indefinitely and create Black Holes. It shapes space and alters time.
Gravity waves are like sounds that travel through space at the speed of light.
Today we are able to see far into the Universe with all sorts of telescopes but so far we are deaf to the sounds of the Universe - we are sill unable to hear. It took scientists 100 years to explore the electromagnetic spectrum. The discovery of electromagnetic waves in 1886 spawned a dramatic and unforeseen revolution as the new waves were progressively harnessed for communication, medicine and astronomy. The next century will be the century of gravity waves. At the very least, gravity waves will allow us to unravel the mysteries of the dark side of the Universe from Black holes to the 'Big Bang'.
