The reading we are covering in class this week can be partly found in this link from NASA.Here is the illustration that was not so clear in our copy (page 7) -at least to me- and which presents the possible scenarios for the size of the universe according to time, from which the red curve is the one our universe seems to be following.
One of our Physics majors, mentioned that the universe started as a "singularity"?!*?!# Go to the second paragraph of this link -if you want to- to find more about it. There is also (guess what?) another video there. That´s right. Quite interesting, though, and it is just 6 minutes. It mentions some of the concepts in Cosmology we have read about lately.
If someone is interested in string theory, here is a reading . There is also a nice video created by NASA about Einstein which discusses key concepts. It is 7 minutes and a half, so watch it only if you are interested and have time ;-)
Arianna recommends this video on the size of the universe, and Alejandro Nunes this one on Milky Way and the reason why it is named that way.
