![]() ![]() It seemed as though there were two separate effects working together. In fact he discovered a direct relationship between distance and the degree of redshift. However Hubble discovered that the greater the distance to the star the more predominant the redshift. For stars close to Earth both redshift and blueshift were observed-indicating that some stars were moving away from Earth and some towards Earth. ![]() When the body moves away from the observer the observed wavelength is increased (redshift) and on appoaching the observed wavelength it is shortened (blueshift). The Doppler effect causes the emitted frequency to be shifted, at the observer, when the emitting body is moving at velocity relative to the observer. The obvious cause of this shift was the Doppler effect. It was observed by Edwin Hubble and others that, most unexpectedly, the wavelength of the absorption lines of certain stars was shifted (altered in wavelength) either towards the red or the blue end of the visible spectrum. These frequencies (shown as dark lines in the spectrum) are known as absorption lines. These frequencies are generated by the star but are absorbed by elements (mainly hydrogen and helium) present in the upper atmospere of the star at frequencies specific to the element. It was discoverd by Frauenhofer that certain very specific frequencies are absent from the spectrum. By passing the light beam through a prism or diffraction grating the amplitude of the light at any particular frequency within the band can be determined. The light generated by a star covers a wide band of frequencies from the infra-red through visible light to the ultra-violet. Modified Newtonian gravity in the outer regions of galaxies is explained. We can only say that the ratio of distance to time (the speed of light) is increasing over time. Hence it cannot be said that Space is expanding. Home Page Abstract The Hubble redshift is currently explained by an expansion of Space distance based on an assumption that the rate of passage of time is constant.
