  1. The Institute of Arts and Ideas: A Goldilock’s World | Chiara Marletto, Bernard Carr, Massimo Pigliucci

    Copernicus and Darwin taught us to be skeptical of feeling we were special. Yet from the size of the electron to the cosmological constant our universe is strangely fine-tuned for life. Is this a spectacularly fortuitous accident? Has the universe been tailored for us or do the theories just make it look that way?

    New York philosopher Massimo Pigliucci, M-Theorist and author of Universe or Multiverse? Bernard Carr, and Oxford constructor theorist Chiara Marletto wonder why we are here.

  2. Stephen Hawking’s “The Grand Design”

    Physicist Stephen Hawking got the world’s attention a long time ago. The brilliant scientist, trapped in wheel chair and Lou Gehrig’s disease, whose mind encompassed the cosmos.

    In “A Brief History of Time”, Hawking laid out what we knew of the universe in compelling imagery and metaphor.

    Now he’s back, with physicist Leonard Mlodinow, for a cosmic update. Not one universe out there, but many, they say. And no need now for God to explain the origin of everything. Science, they say, will do it.

  3. Neil Turok - What Banged? (Perimeter Institute for Theoretical Physics)

    The evidence that the universe emerged 14 billion years ago from an event called ‘the big bang’ is overwhelming. Yet the cause of this event remains deeply mysterious. In the conventional picture, the ‘initial singularity’ is unexplained. It is simply assumed that the universe somehow sprang into existence full of ‘inflationary’ energy, blowing up the universe into the large, smooth state we observe today. While this picture is in excellent agreement with current observations, it is both contrived and incomplete, leading us to suspect that it is not the final word. In this lecture, the standard inflationary picture will be contrasted with a new view of the initial singularity suggested by string and M-theory, in which the bang is a far more normal, albeit violent, event which occurred in a pre-existing universe. According to the new picture, a cyclical model of the universe becomes feasible in which one bang is followed by another, in a potentially endless series of cosmic cycles. The presentation will also review exciting recent theoretical developments and forthcoming observational tests which could distinguish between the rival inflationary and cyclical hypotheses.
