Capturing Christianity - Is There a Future Contingent?

Kirk: I think it's better just sort of summarise where we've gone and then close out the live stream. So if you have t a question, then make sure to ask it in the live chat and tag at capturing christianity,. that way i can see it. The first one's from andrew graham. He says given that time travel is impossible, how are we supposed to check that coins have been flipped, or even if the coins exist? A i'm not sure who's that? Who? That is addressed to kirk. Why don't you take dowon first, and then will? All right. We'll do summaries after the questions.
