Suppose that new measurements prove that our data on the spectral shifts of the galaxies are correct, but that all the distances of all of the galaxies are actually double of what we think they are today. How would the doubling of the distances affect Hubble’s law?
A. Changing the distances would disprove Hubble’s law.
B. It would show that the Universe is expanding twice as fast.
C. Hubble’s law would still hold, but the value of the Hubble constant will have to be revised.
D. None of the choices are correct

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
