A quasar (believed to be a galaxy in formation with a super-massive black hole at its center) is a pointlike object that has tremendous energy output, is very distant from the Earth, and has a large redshift. Its speed can be measured from Doppler-shift measurements of the light it emits. A certain quasar recedes from the Earth at a speed of 0.55 c. (a) How far away is it? (b) Assuming that the quasar has moved with the speed 0.55 c ever since the Big Bang, estimate the age of the Universe. | Nu
