Dear all,
Our final colloquium for the Winter semester will be given by Professor David Garfinkle from our Department of Physics. David will talk about "Cyclic Cosmology", please see the abstract below.
The colloquium will take place in MSC 185 from noon to 1 pm on Thursday, April 16. Please join us for this intriguing talk!
Abstract: One striking feature of the early universe is that the density of matter and energy is almost exactly the same everywhere. The usual explanation for this uniformity is a period of very rapid expansion shortly after the Big Bang. Instead we consider the possibility that the uniformity was produced before the Big Bang, at a time when the universe was contracting.
