The Red Shift..."Universe Ungraveled" !!

                                         The Red Shift

Have you ever wondered how the hell scientists come to know whether a planet, satellite or any heavenly body in approaching towards earth or not. This would have been quite tough, and up till now, several accidents may have taken place. The hero for this tragedy was Mr.Albert Einstein, he gave the principle of THE RED SHIFT.

 

 

THE RED SHIFT is a phenomenon which occur when any light emitting or luminous object approaches or goes away from earth or the observer in the space. What happens is when ever any object emitting light approaches the observer, the light color of the body which is seen by the observer changes. It starts to shift opposite of V.I.B.G.Y.O.R....... that is...Violet.Indigo.Blue.Green.Yellow.Orange.Red...so when the object comes near the shift is from red up to violet...so the nearest star you will see will be in violet color and the furthest will be in red color.......now you may guessing the reason, why the back light of vehicles is in red color. The most important reason is that its penetrating power is highest. So atmosphere does not disturb it a lot.     

This is used by the super computers to calculate the speed of coming body and its distance,the quicker the shift is taking place the quicker the object is traveling. If  going away then it is called THE RED SHIFT, and if coming towards us then THE BLUE DRIFT. This happens because of the different wavelengths of light and their power of penetration. If very far we will see only red color and as it approaches us we can see blue, green etc.....
