If a distant galaxy has a substantial redshift (as viewed from our galaxy), then anyone living in that galaxy would see a substantial redshift in a spectrum of the milky way galaxy. choose the correct explanation why the statement makes sense (or is clearly true) or does not make sense (or is clearly false).
a) this statement makes sense. the redshift means that we see the galaxy moving away from us, so observers in that galaxy must also see us moving away from them—which means they see us redshifted as well. b) this statement doesn't make sense. the redshift means that we see the galaxy moving to us, so observers in that galaxy must see us moving away from them—which means they don't see us redshifted. c) this statement makes sense. the redshift means that we see the galaxy moving to us, so observers in that galaxy must also see us moving to them—which means they see us redshifted as well. d) this statement doesn't make sense. the redshift means that we see the galaxy moving away from us, so observers in that galaxy must see us moving to them—which means they don't see us redshifted.
