Paul Sykes Memorial Lecture - What Banged? by Neil Turok

What Banged?

Over the last two decades, our knowledge of the Universe has improved enormously. Powerful new observations have lent overwhelming support to the notion that everything in the visible Universe emerged from a Big Bang, fourteen billion years ago.
But what caused the Bang? And was the Bang the beginning of time?
Only a few decades ago, these questions were considered beyond the reach of science. However, unified theories of high energy physics have allowed us to build mathematical models of the Bang itself, and to test them both for logical consistency, and against new observations.
In the lecture, Dr. Neil Turok will review two models: one in which the Universe began at the Bang, and the other in which the Bang was a violent event in a pre-existing Universe.
The competition between these models lies at the heart of many deep questions about the Universe, and about our ultimate ability to understand it.

    I belive I started to understand a few things about the begining of the univers from a sub atomic point of view.

    Dr. Turok approached his specialty - the early evolution of our Universe - with humour, well-explained the subject in light of the most recent astronomical and particle-physical discoveries. The topic was presented in a way which which would give even those people unfamiliar with, but with a natural curiosty about the reasons for why we see the universe the way we do, a general understanding of the subject. The limits of our knowledge in this area and the direction we should take in further research were well illuminated.

    Neil Turok gave an excellent example of how the scientific method is supposed to work. He made it very clear the role of the theorist as opposed to the experimenalist. The math was far beyond my abilities, however I feel I got a feel for the concepts the math represented. I have read about his work so it was a thrill to hear him explain it in person. A great time.

    Very interesting theories! Fascinating to learn about the 2 branes collision model as an alternative. For the lay audience, it might have been better to have skipped some of the detail (math equations) and instead explained with pictures and a more entertaining lay perspective than in a research talk format. However, I'm sure the physicists in the audience would disagree!, it is difficult to explain the complexities of the alternative theories without resorting to scientific detail.

    I thought the presentation was great, the charts and the graphics made the experience more easy to understand and I very much appreciated the session. Thank you for organizing the group.

    I thought this was a fantastic lecture. I'd attend another one like this in a heartbeat.

    I have learned a lot more about theoretical physics and i hope more of these lectures will come up in the future.

    It was an excellent and thought provoking lecture . Neil was one of the best speakers I've heard - some nice humor thrown into it.

    Excellent talk and choice of speaker.

    I don't know much about physics, so a talk by a theoretical physicist might seem a bore. Although much of what he discussed did go over my head, I did learn a lot and, perhaps more importantly, the bounds of my understanding were challenged and expanded: how can we grow and be challenged to do so if the toughest intellectual challenges before us are understanding the political and social references made on a late-night mock TV news magazine or decide which pundit has presented a more compelling argument about what should be done in Afghanistan or about the current economic situation? Where can I go to be exposed to the calibre of intellectual exploration presented in this lecture? Unequalled intellectual stimulation. Thanks to Paul Sykes, the RASC-V and Neil Turok.

    Is this event free? By donation?
    Thanks in advance! :)
