The Big Questions in the Universe
The First Stars. Eddington once famously said that a physicist on a cloud-bound planet could predict that there are stars. The first series of lectures will be devoted to fundamental questions that have simple answers. What is a star? What is a galaxy? All revolves around knowing their masses. Why should a star like the sun weigh in at two billion trillion trillion tonnes? No more, no less. And all other stars, countless in number, are between a tenth of a hundred times the mass of the sun. This leads us into a description of the first stars in the universe.
Gresham Professor of Astronomy, Joseph Silk FRS, is one of the world's leading experts in theoretical cosmology, dark matter, galaxy formation and cosmic microwave background.
