Cougar: Here [in running the movie backward] your answer is incorrect. We can't get anywhere near 10^-43 sec. From my recent reading on the subject, many major names in the field all seem to agree on how the movie would rewind back to 1 second.

dcl: I suggest you broaden your reading. There are any number of respected sources that give that 10^-43 figure. That figure comes from the Standard Model of particle physics, not from accelerator experiments.

Cougar: Ha ha! Now that is truly funny. Would you like to peruse my Recent Reading list? I believe the misunderstanding about what we currently know [about] when the universe was 10^-43 seconds old is yours.

dcl: I note your long list of references, most of which appear to be either outdated or totally irrelevant to the question of how far back in time the history of the Universe has been traced via the Standard Model of particle physics. It suffices for me to cite just one reference to rebut your assertion that the movie can be rewound only to 1 second. On page 155 of James S. Trefil, "The Moment of creation", Macmillan, New York, 1983. You can find the following statement, quoted verbatim from page 155 of this book.:

. "We will call the period from 10^-43 second to 10^-35 second after the Big Bang the GUT, or Grand Unification Theory, era."

Trefil is a professor of physics at Stanford University. Perhaps you'd like to challenge him on that figure. His response should be even funnier than was yours to my earlier statement.
