Radio Astronomy

Related to the previous post, I came across this in TED today. Apparently, the field of Radio Astronomy is all about listening to the sounds of Universe. We learnt of the 'Big Bang' through the sound from space. The fabric of Space is the drum on which the matter and time bang on! Listen in to the sounds of the Universe.

Music and Universe

I don't have to explain the power of music on life. Music is a universal language that reaches and touches every single human life on earth. We humans reach out to divinity through music singing, listening, composing, melting and absolving ourselves in the power of music. Historically music and world religions have grown hand in hand. Hindu depiction of Gods all have a musical instrument with them.

Yet the thought that there is no sound and hence no music outside of the earth is bizarre to me. Space is filled with darkness and light, as we know of it at this time. But no air and hence no sound and no music! This huge ball of earth is spinning at an incredible speed of 1070 miles/hour (approx) in total silence! When I speed up my car above 60 miles/hr I hear the penetrating sound of wind against the car. But rockets, satellites, planets and other objects in space are in perpetual motion in the friction-less silent space.

We store and retrieve sound as light signal in our digital music CD. Satellite radios transmit/receive signals through space as electromagnetic waves. Could it be that the light we receive from Sun and Stars have an encoded message for us as music to our ears...!? Musicians declare that all natural sounds have music, like the sound of ocean waves, chirping birds, barking dogs, etc. Could there be sound of music from outside of the earth!?
