- In the reading, you were told that there were roughly 10,000 galaxies in the image of the Hubble Ultra Deep Field alone. The image is roughly 10 square arcminutes and there are roughly 1.5*10^8 square arcminutes composing the entire sky. With that in mind and assuming that the Hubble Ultra Deep Field represents an average part of the sky, roughly how many galaxies may exist in the observable universe? (Please include commas for every factor of 1,000; for example 2,343,567,890)what evidence is there that galaxies collide and merge?Place all of the following in order from earliest to the most recent: Dark energy begins acceleration of the expansion of the universe You study for your final in astronomy Last scattering of the Cosmic Microwave Background Radiation First stars and galaxies form Big Bang Universe becomes transparent (no longer opaque) aka photon decoupling time Inflationary Epoch Formation of first complex elements (hydrogen isotopes, helium & lithium)
