We'll build today we conclude our series of podcasts responding to a YouTube video which features

an impressive array of philosophers and physicists, critiquing the Kalam cosmological argument

and specifically targeting you. It's called physicist and philosophers reply to the Kalam cosmological

argument featuring pen rows honking and goof. It fits neatly into four segments so we're concluding

with our fourth podcast today. We've looked at the first philosophical argument for the beginning

of the universe and the first podcast, the second philosophical argument for the beginning of

the universe and the second one. Last time we looked at the scientific evidence for the beginning

of the universe and today the need for a cause of the universe's beginning and we'll just offer

this disclaimer again that there's no way we can possibly respond to everything in the video

in these short podcasts but Bill you've also included some more material in the question of the

weak feature at reasonablefaith.org so by everyone to go there. 770 to 773 will cover all four

sections of the video. Let's go then to the first excerpt in the video today. The big band doesn't

prove the universe had a beginning only that it evolved from a very hot dense state but when it

comes to physics the Kalam advocate has another card to play. The second law of thermodynamics.

The second law states that entropy which is roughly a measure of disorder increases with time

and so the argument goes if the universe were eternal into the past we would already be in a

maximal entropy state. Since we aren't the universe can't be past eternal. This also related to

the mystery of why the big bang was in a surprisingly low entropy state but what if the universe

were infinite? Perhaps we're living in a physical system where there's no maximum possible

entropy. Suppose the entropy can just grow forever and an eternally inflating universe looks like

such a system although nobody really knows for sure how to define the eternally inflating universe

but if it's the case that entropy can grow forever then any state is a state of low entropy
