Why Is the Use of Hubble's Law to Measure Distances

question 2

Multiple Choice

Why is the use of Hubble's Law to measure distances to galaxies so important to astronomers?

• A) They have NO other way of measuring distances to galaxies - absolutely none
• B) Many galaxies don't move away from us, so when we find one that does, it's really a big deal
• C) Most galaxies are so far away, the only way to get distances to them is to use Hubble's Law
• D) The other ways of getting distances only work for really far away galaxies; so the Hubble Law is the only way to measure distances to nearby galaxies
• E) It's stretching the truth to say that Hubble's Law is a really important way to get distances to galaxies; really, it's no more important than any other method
