Yes of course it would. This is what my brother finds out all the time. His measurements of the radial velocities of the stars he observes change by exactly twice the earth's orbital velocity during a year. Alan I thought I had a means of proof of earth around the sun, but on second thoughts there is a complicated other answer for this doppler shift that occurs to me. But I have to admit it is stretching my credulity. see a previous post today. Why would God go to so much trouble to trick Scientists. Is it perhaps because they have no humility. We have to accept that their whole thrust even if not individually but as a group is anti God. Their pride in effect deceives themselves. Just wondering.
