Hubble discovered that ... *1 pointGalaxies are all moving away from us at the same speedGalaxies that are closer to us are moving towards usGalaxies that are closer to us are moving away from us fasterGalaxies that are closer to us are moving away from us slower than those farther from us

What does Hubble's Law mean?The recommended time to answer this question is 2.5 minutes.Soru 23YanıtAll galaxies are moving away from us at a constant speed.The further a galaxy is, the slower it moves away from us.The further a galaxy is, the faster it moves away from us.The further a galaxy is, the faster it approaches us.All galaxies approach us at a constant speed.

Select the option that best completes the following sentence. The discoveries of Slipher and Hubble revealed that:most galaxies are moving towards a common pointmost galaxies are getting further away from us, moving faster the further away they aremost galaxies are getting further away from us, all at about the same speedgalaxies stay in fixed positions

How did Hubble know that the galaxies he observed were moving away from us? aThe spectra of the stars were red-shifted which indicates they were moving away rapidly. bThe spectra of the stars were blue-shifted which indicates they were moving away rapidly. cThe spectra of the stars were violet-shifted which indicates they were moving away rapidly. dThe spectra of the stars were green-shifted which indicates they were moving away rapidly.

Hubble discovered that more distant galaxies have greater redshift (greater recession velocity).Group of answer choicesTrueFalse

According to Hubble's Law, the greater a galaxy's redshift, theGroup of answer choicescloser it is to us.faster it's approaching us.younger it is.farther it is from us.greater its mass.
