Cosmologic philosophy: dark matter first (Introduction)

QUOTE: Using a new, simple mathematical framework,the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflationwhen space was expanding very rapidly. (David’s bold)

DAVID: Most folks in cosmology think time started with the Big Bang. Note my bold. Inflation is thought to have appeared after the Big Bang, not before. I think this reporter is confused about the mathematical study or the study is confused in its conjectures.

dhw: I think there is confusion all round. If there was a Big Bang, there must have been a “before the Big Bang”, which means time did not start with the Big Bang, unless you believe in an effect without a cause. Nobody has a clue what existed before the Big Bang, but since “dark energy” and “dark matter” simply mean something we know nothing about, we might just as well say that the Big Bang, if it happened, and the resultant progression of universe to Milky Way to Planet Earth to bacteria to humans and the duckbilled platypus were the result of unknown forces. That, I suggest, is a precise description of our knowledge at the moment.

DAVID: 'Effect without cause'? Commented upon as a true Agnostic. How about a timeless eternal God as the cause?

Yes, yes, we’ve been over that a thousand times. The alternative first cause is mindless energy and matter infinitely and eternally forming new combinations. Now please tell me if you believe the Big Bang was an effect without a cause, and therefore marked the beginning of time. Meanwhile, would you agree that my summary, beginning “nobody has a clue…” provides a precise description of our knowledge at the moment?
