There is no such thing as a free lunch, some say, but they would be wrong. In fact, the entirety of the universe defies them. According to Stanford physics Professor Andrei Linde, one of the architects of the inflationary theory, our universe (and all the matter in it) was born out of a vacuum.


"Recent developments in cosmology have irreversibly changed our understanding of the structure and fate of our universe and of our own place in it," says Linde, who will discuss the inflationary view of the universe at the annual meeting of the American Association for the Advancement of Science on Feb. 18 in San Francisco.

In the same session, titled "Multiverses, Dark Energy and Physics as an Environmental Science," physics Professor Leonard Susskind of Stanford will talk about string theory and its relation to inflationary theory and physics Professor Lawrence Krauss of Case Western Reserve University will represent the skeptic view.

The conventional theory of the Big Bang says that the newborn universe was huge, containing more than 10^80 [ten raised to the power of eighty] tons of matter. But physicists were stumped for an explanation of where all this matter came from. Inflationary theory solves this problem by showing how our universe could emerge from less than a milligram of matter, or perhaps even from literally nothing.
