How does the universe create galaxies and how can a structure of that size possibly exist?: http://www.gresham.ac.uk/professors-and-speakers/professor-joseph-silk

By examining the “ripples” that have been seen in the Cosmic Microwave Background, astronomers are beginning to unpick the origins of enormous stellar structures like galaxies. The mysteries of why  they form and where are slowly being unravelled 

Joseph Silk is a renowned cosmologist who currently holds posts at three of the world’s top Universities: John Hopkins University, Le Sorbonne and the University of Oxford. Professor Silk is one of the world’s leading experts in theoretical cosmology, dark matter, galaxy formation and cosmic microwave background. Professor Silk’s studies of galaxy formation and his work on the dynamics of mass loss and the feedback mechanisms from star formation and evolution formed a highly significant basis for subsequent work in this important field. In 2011 he won the Balzan Prize for this pioneering work on the infant universe.

Professor Silk's inaugural series for Gresham College is titled 'The Biggest Questions in the Universe'. In six lectures, Professor Silk will examine the earliest moments of the Universe; discuss the first stars and the future of the field as 'galactic archaeology' expands our understanding of the Universe. You can see all of the lectures on the website: http://www.gresham.ac.uk/the-biggest-questions-in-the-universe
