What Banged? Top Scientist Neil Turok at Canada’s Perimeter Institute to Share Insight on Deepest Mysteries of the Cosmos

28.02.2008
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.

On Wednesday, March 5th, at 7:00 pm, Perimeter Institute will examine this deep mystery in science with preeminent physicist Dr. Neil Turok, Cambridge University, in a sold-out public lecture. Dr. Turok will provide many insights, including those outlined in his recent book co-authored with Dr. Paul Steinhardt – ‘Endless Universe: Beyond the Big Bang’ – in which there is a view that the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars and planets.

In this presentation for a general audience, 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.

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
