Question
Is it possible for us to measure the speed at which galaxies move?
- Yes, we can measure by using precision astrometry, and we can watch their position change over many years.
- Yes, we can measure from their redshift or blueshift, and we can find their speed towards us or away from us.
- Yes, we would, like we do for stars, but actually, we would find that galaxies do not move.
- No, it is not possible because they are too far away.
Hint:
We can measure the speed at which the galaxy moves from their redshift or blueshift, and we can find their speed towards us or away from us.
The correct answer is: Yes, we can measure from their redshift or blueshift, and we can find their speed towards us or away from us.
- The movement and speed of the galaxy can be measured by using red shift and blue shift.
- The red shift and blue shift explain the shift of light towards long and short wavelengths.
- The spectrum of light can be measured by redshift.
