Which of the following is an INCORRECT statement regarding the expanding universe theory? A. Scientists were able to observe that all galaxies and star clusters are moving away from Earth because of the shift of the wavelength to the blue part of the visible spectrum. B. Slipher from 1912 to 1914 studied the electromagnetic radiation of nearby spiral galaxies where he observed that wavelengths of yellow lines appear to be a little orange. C. More recent observation using powerful telescopes confirm that frequency of light from nearby galaxies and star clusters decreases as it is observed here on Earth. D. From the amount of Doppler shift, astronomers are able to compute for the speeds and determine the direction of the motion of nearby galaxies and star clusters.
