Dear Geoff,
The details of the calculations can be found in my book published in 1990. Its electronic version can be found here http://arxiv.org/pdf/hep-th/0503203.pdf I am sure that you can calculate things correctly using it, but please note: different versions of inflationary theory give different answers. We are still trying to determine which of these theories is better. And, by the way, nobody estimates the age of the universe as 15.8 billion years. It is 13.8 billion years.
Best wishes
Andrei

Dear Professor Linde,Kindly explain how the figures about the ‘’the trillionth of a trillionth of a trillionth of a second quoted in The Australian article, became ‘’millions and billions as delivered by you on a video on The Australian’s website.‘’The theory posits that less than a trillionth of a second after the Big Bang, the universe expanded by a factor of 100 trillion, trillion times.’’This represents thousands of billions of percentage points variation. It may or may not make that much difference if you could kindly explain how the figures were arrived at basis either of the scenarios. Note also please that the former is represented by 1 and 36 zeroes.Then kindly give my students an idea as to how you arrived at your calculations representing events of such astonishingly brief duration 15.8 BILLION years ago. We have always been fascinated by large / ultra – small numbers: did you ever think of using google plex as a means of delineating these figures?Sent: Monday, March 24, 2014 11:47 AMSubject: Greetings from Australia to Prog Kovac!Email:

Cambridge, MA 02138Dear Professor KovacI read about your ‘Inflation’ theory in The Australian on March 19. See the video also hereunder by Professor Chao Lin Kuo and ‘the founding father of Inflation theory’, Prof Andrei Linde.‘’The theory posits that less than a trillionth of a second after the Big Bang, the universe expanded by a factor of 100 trillion, trillion times.’’I hope you win the Nobel Prize. As an amateur mathematician may I offer some constructive advice?You may care to respond to these questions and perhaps adjust your material for our consumption. Much appreciate – I am sure you have all the data ready. We do understand numbers.You may care to try to get those figures right. About the ‘’the trillionth of a trillionth of a trillionth of a second in The Australian, became ‘’millions and billions as delivered by Prof Linde.Note also that the former is represented by 1 and 36 zeroes. Far more accurately delineated.The latter is at huge variance by millions of per cent. Not elegant. Indeed it may not matter if you do not respond to other arenas herein this epistle.Could you send me your calculations as to how you either of the above were calculated? I tutor people in the higher forms of large numbers and they are keen to understand why you did not use google plex: surely more manageable? AND of course – read below please.We are also not able to appreciate the margin of error over 15.8 Billion years and how you accounted for it via your "five-sigma" certainty’’ to millions to one certainty. In two realms that clearly add to the potential for error by far to great a figure to meaningfully calculate here.We would like to learn more about these theoretical calculations of yours.Please note that these comments pasted here also appear to be inelegant – for completely disparate reasons. I hope you understand what is implied – as it would take too long to elucidate.‘’The theory posits that less than a trillionth of a second after the Big Bang, the universe expanded by a factor of 100 trillion, trillion times.’’Yours SincerelyGeoff SeidnerEast St KildaMelbourne AustraliaPSInflation theory elicits Zimbabwe and post war Germany: surely one of them tangents are strained? Your title is seemingly trite- you may consider
