If a galaxy moving away from the Earth has a speed of 1000 km/s and emits 656 nm light characteristic of hydrogen (the most common element in the universe). Why is the speed of the Earth in its orbit negligible here?
On average, how far away are galaxies that are moving away from us at 2.0% of the speed of light?
What is the event horizon radius [m] for the sun if it were to collapse to a Schwarzschild black hole? (Msun = 1.99 x 1030kg). Would earth’s orbit be altered if this were to occur (although it would be a heck of a lot colder) (T/F).

- Given an object is receding from Earth at v=20(10^3)km x s^-1, Calculate its redshift z?arrow_forwardAll galaxies farther away than about 50×106 ly exhibit a red shift in their emitted light that is proportional to distance, with those farther and farther away having progressively greater red shifts. What does this imply, assuming that the only source of red shift is relative motion? (Hint: At these large distances, it is space itself that is expanding, but the effect on light is the same.)arrow_forwardSuppose a distant quasar has a redshift of 6.

- Some of the familiar hydrogen lines appear in the spectrum of quasar 3C9, but they are shifted so far toward the red that their wavelengths are observed to be 3.0 times as long as those observed for hydrogen atoms at rest in the laboratory. (a) Show that the classical Doppler equation gives a relative velocity of recession greater than c for this situation. (b) Assuming that the relative motion of 3C9 and Earth is due entirely to the cosmological expansion of the universe, find the recession speed that is predicted by the relativistic Doppler equation.arrow_forwardDescribe the Einstein’s Postulates?arrow_forwardThe classical Doppler shift for light.

(In other words, no galaxy we observe can be moving away faster than the speed of light.)arrow_forwardExplain why it only appears that we are at the center of expansion of the universe and why an observer in another galaxy would see the same relative motion of all but the closest galaxies away from her.arrow_forward
