Episode notes

In the eternal case, where things have always existed, there's not this implication that they sort of were created at any one moment. The big bang was just the first moment. It didn't pop into existence. If you think about it from now going backwards, rather than before the universe going forwards, if yo start from now and go backwards,. You hit an end, and that's it. And it makes sense, in retrospect, that this can happen in the case when the universe has zero energy.

It's fun to be in the exciting, chaotic, youthful days of the podcast, when anything goes and experimentation is the order of the day. So today's show is something different: a solo effort, featuring just me talking without any guests to cramp my style. This won't be the usual format, but I suspect it will happen from time to time. Feel free to chime in below on how often you think alternative formats should be part of the mix. The topic today is "Why Is There Something Rather than Nothing?", or equivalently "Why Does the Universe Exist at All?" Heady stuff, but we're not going to back away from the challenge. What I have to say will roughly follow my recent paper on the subject, although in a more chatty and accessible style. It concerns ideas at the intersection of physics, philosophy, and theology, so tune in if you're into that sort of thing.

After a number of people have asked, I have finally opened a Patreon account for people who would like to support Mindscape in some way. You can sign up to kick in a dollar or more per podcast episode, and in return you get 1) access to occasional Ask Me Anything episodes done exclusively for patrons, and 2) my undying gratitude. If the Patreon route is successful enough, I'll forego having ads on the podcast -- we'll see how it goes.
