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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
