Which of the following statements is NOT true:
a) Light moving from a source moving toward the observer will have a higher frequency than if the source were at rest with respect to the observer.
b) The value of Hubble's parameter, H, is determined by measured redshifts of spectral lines for distant galaxies. c) Hubble's parameter, H, is used to estimate both the Universe's size and age.
d) According to Hubble's Law all galaxies must be moving away (receding) from our own.

Respuesta :

D) according to Hubble’s law all galaxies must be moving away (receding) from our own.

The question about the finding the true statement based on the space.

  • Hubble's law is based on the observed physical cosmology and the galaxy that are moving .
  • The speed of earth is proportional to their distance. Thud on their basis the universe is expanding. The expansion is called as Hubble flow.
  • Hubble parameter H is  dimension less title. It is a fundamental cosmological property. H, is not used to estimate both the Universe size and age of galaxies.

Hence the option C is correct.
