Well, Bill, we're responding to a YouTube video that's getting quite a lot of views.

It's called Physicist and Philosophers reply to the Kalam Cosmological Argument, featuring

Penrose, Hawking, and Gooth.

Fits neatly into four segments, so we decided to do a four-part series in our podcast.

We dealt with the first philosophical argument in the first video, and then the second philosophical

argument for the beginning of the universe and the second podcast.

Today, we're going to look at the scientific evidence for the beginning of the universe,

which they address next.

Now, again, there's just no way that we can possibly respond to everything in the video,

but we are playing the representative clips of this program.

And Bill, you're also responding to this video in the question of the week feature.

So our listeners and viewers can get more when they got a reasonable faith.org.

Here's the next excerpt from the video.

The infinite future is not the only infinity, supporters of the Kalam tend to embrace.

They've also claimed that the big bang singularity proves a beginning of time.

It bribes at a state of infinite density at some point in the finite past.

This state represents a singularity at which spacetime curvature, along with temperature,

pressure, and density, becomes infinite.

It therefore constitutes an edge or boundary to spacetime itself.

The argument by Lane Craig that the infinite past is impossible, and therefore that conception

of the universe is untenable, is incompatible with their claim that there is a singular

point at which the universe originates, because the properties of that singularity are entirely
