Cosmologic philosophy: Egnor on Big Bang, etc. (Introduction)

DAVID: You are still missing the point that time can exist only within previous BB's.

dhw: You are still ignoring two points: 1) that the possibility of previous BBs makes nonsense of Guth & Co’s claim to have “proven” that time did not exist before our BB; 2) that if time is a sequence of before-during-after, you have a before-during-after every BB, and so time exists between BBs as well as during BBs.

Guth et al. only discussed our BB. You want time to exist during timeless eternity between BB's, because of an imagined sequence. That is our concept of time within our BB which has time in it.

DAVID: Your twisted interpretation continues. Exactly before this existing BB there was no 'before' (as interpreted as time). Guth et al and cosmologists and I accept this. All we can know is time starts at our BB. Anything before is imagined and has created this long discussion.

dhw: You simply refuse to recognize your own objection to Guth & Co! Nobody can know what existed before our BB. Guth & Co imagine “nothing” – no before. You imagine God before. And you imagine the possibility of earlier BBs before. Why do pretend to accept what they imagine and reject what you yourself imagine?

I'm doing no such thing. Time exists only within a BB, not between them.

Cosmologic philosophy
DAVID: Using the concept of entropy, time can only exist if time is started at an event of high energy, i.e., after a BB. Time exists only after a BB.

dhw: Time is not “started”. Time is not a clock. You have agreed that time is the word we use to describe a sequence of before-during-after. I agree that this requires events – you can’t have a sequence without events. For example, time exists before-during-after our writing our posts for this website, and time would exist before-during-after BBs.

You are still using our concept of time in our BB which has time. There is no exiting time between BB's if there have been multiple BB's. Your imagined sequence cannot create time in fact, only in your imagination.
