It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that’s possible in the new book, The Hidden Reality.

Cafe Scientific -The Gloriously Messy Universe!
Is there an ultimate theory of everything? Could it be possible that after decades of searching, it may turn out that the universe is not perfectly and elegantly designed? According to author Marcelo Gleiser, the universe is gloriously messy and we hear his controversial views…. along with alternative views from our panel of astronomers. This forum was recorded at the 2010 Brisbane Writers festival and your host is Dr Paul Willis from ABC TV´s Catalyst program.

To The Best of Our Knowledge: The Universe
Leonard Mlodinow and co-author Stephen Hawking say that you can explain the existence of everything without requiring God. Charles Yu’s novel details some of the perils of existence in multiple time streams. James Kakalios says that some of the early quantum physicists were inspired by science fiction. John Polkinghorne is the author of many books on the subject of bridging the gap between science and religion. Michio Kaku tells us exactly why the impossible just takes a little longer.

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.

In Out Time: The Measurement Problem In Physics
Melvyn Bragg is joined by Roger Penrose, Basil Hiley and Simon Saunders to discuss the bizarre nature of atoms and the conundrum at the heart of quantum physics
The measurement problem arises because we don’t really understand how the atoms that constitute our world behave. They are fundamentally mysterious to us, even shocking, and they defy our attempts to measure and make sense of them. Possible solutions range from the existence of multiple realities to the rather more mundane possibility of an error in our mathematics - but a solution, if found, could transform our understanding of reality.
