Question
evaluate the following claim: the universe is not expanding because galaxies only appear to move due to earths what evidence contradicts this claim? a stellar parallax of a nearby star b the consistent redshift pattern from distant galaxies c the moons gravitational effect on tides d the daily motion of the sun across the sky
Stellar parallax is related to the distance - measurement of nearby stars and not to the expansion of the universe. The moon's gravitational effect on tides is a result of the gravitational interaction between the Earth, moon and sun and has nothing to do with the expansion of the universe. The daily motion of the Sun across the sky is due to Earth's rotation. However, the consistent redshift pattern from distant galaxies is evidence of the Doppler effect caused by the galaxies moving away from us, which supports the idea of the universe's expansion.
