Einstein, Simon and Garfunkel...

Hello darkness, my old friend
I've come to talk with you again
Because a vision softly creeping
Left its seeds while I was sleeping
And the vision that was planted in my brain
Still remains
Within the sound of silence


In restless dreams I walked alone
Narrow streets of cobblestone
'Neath the halo of a street lamp
I turned my collar to the cold and damp
When my eyes were stabbed by the flash of a neon light
That split the night
And touched the sound of silence


And in the naked light I saw
Ten thousand people, maybe more
People talking without speaking
People hearing without listening
People writing songs that voices never share
And no one dared
Disturb the sound of silence


"Fools", said I, "You do not know
Silence like a cancer grows
Hear my words that I might teach you
Take my arms that I might reach you"
But my words, like silent raindrops fell
And echoed
In the wells of silence


And the people bowed and prayed
To the neon god they made
And the sign flashed out its warning
In the words that it was forming
And the sign said, "The words of the prophets are written on the subway walls
And tenement halls"
And whispered in the sounds of silence

Einstein wrote about them, and we're still looking for them - gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe.

Just as sound complements vision in our daily life, gravitational waves will complement our view of the universe taken by standard telescopes.

Albert Einstein predicted gravitational waves in 1918. Today, almost 100 years later, advanced gravitational wave detectors are being constructed in the US, Europe, Japan and Australia to search for them. While any motion produces gravitational waves, a signal loud enough to be detected requires the motion of huge masses at extreme velocities.
