Red Shift (
1973) is a complex story for teenagers and adults set in three intertwined time periods spanning 900 years but one geographical area: Mow Cop in [Staffordshire, England]
?.
Alan Garner evokes the essence of place, allowing his characters to echo each other through time, as if their destinies may be predefined by the soil on which they walk. These are themes explored more tangibly in his easier, earlier work '[The Owl Service]
?', but brought here to maturity in a weave of rapid, impressionistic dialogue.
Red shift is also a natural phenomenon observed by astronomers observing distant galaxies. The light from sources moving at significant speed away from the observer appear to be lower in frequency. This is easily measured because the emmision and absorbtion patterns for molecules are distinctive. This can provide a means of measuring the speed between the source and the observer.
[Edwin Hubble]
? was one of the primary researchers in this area. If the light source is moving towards the observer, a
blue shift is seen. Red and blue shifts are a consequence of the
Doppler effect on light waves.
One of the most significant consequences of distant galaxies' red shift is that if all of them are increasing their distance from one another, going backwards this leads us to the
Big Bang theory.
