WNYC’s Radiolab is a radio show and podcast that has introduced me to the ideas of godless heathens.
Ok, well, Radiolab is a show that covers a different topic every week that relates to science, philosophy or the human experience. It’s complicated to explain but at its core are Jad Abumrad and Robert Krulwich, two guys who riff off one another to try and string everything together.
I want to talk about two of the shows that I listened to. They introduced ideas that would make some question, some take offence and others, like me, feel like the world is magic again. I apologise that the ideas are buried in 60 minute audio files but, like a good book, it’s worth it. Just shut off your obsessive multitasking for a while and listen. You don’t have to read what I write here but at least go listen.
(So Called) Life
In the episode, (So Called) Life, they explore the idea of humans tinkering with DNA. There’s this one seed of an idea in there that’s really powerful: a bunch of students have to do experiments with E. coli but it smells awful. They find a place that sells genes for producing nice odours, they buy a nice one and they breed new bacteria that smells better. Cool solution, right? But they just invented a new form of life! Previously, no E. coli known to man smelt this way.
The episode also briefly talks about places that create synthetic genes. You just pay them and tell them the DNA sequence and they build it. How different is it to paying a company to build you a piece of software? Or perhaps designing a piece of furniture to be built and added to your home?
Forget all the scary stories of designer babies, cloned sheep and genetically modified food for a second and just think about the opposite side of the spectrum. Students dicking about with some bacteria in a petri dish. A bunch of Gs, Ts, Cs and As in a sequence. It’s not that different from traditional computing. Life Itself, as a computing system.
Make me an algae that eats carbon dioxide and poops out bio-diesel. Make me a cow that grows human hearts on the outside like an apple tree grows apples. Make me a living sac that I can attach to me and it will just feed me with nutrients and deflate like a juice box. Make me a pet Godzilla. Is there really anywhere to draw the line?
The (Multi) Universe(s)
The second episode I want to mention is, The (Multi) Universe(s), which is just my favorite thing in the entire world. It’s an idea that is getting more popular in science fiction and basically there’s an infinite number of universes with infinite versions of you and even more infinite slightly different versions of you. Somewhere in this other universe, there’s a person with your looks, your hopes, your dreams reading this blog. They have the exact same thoughts contained in your head right now. They just started pondering if having an exact double is possible.
You could say that’s impossible. But, in the example they use, it’s hard to imagine flipping a coin and getting heads 4000 times in a row. But if you keep flipping, you’ll get it eventually, right? Just keep flipping, the probability is there. 50% to the power of 4000 or something. So in a big-ass infinite universe, why not the probability there’s another Jack? Or a Jack with one more eyelash. Or a Jack who has blond hair. Or a Jack who likes watching Oprah.
One assumption we are making is that creating an exact copy of Jack is just getting the right combination of particles in the right place at the right time. We’re assuming there’s not unique “kiss of God” here. I’m just a collection of atoms arranged in a certain way. Arranged another way, I might be a very large fruit smoothie.
Let’s keep this assumption because the really interesting part is coming up. They introduce this amazing concept that anyone who enjoyed The Matrix would love. Think of how ridiculously improbable it is that you could roll the dice and create our universe as it is now. This cute little solar system supporting this tiny blue speck that’s covered in water and intelligent life forms. Consider how much boring shit there is out in space; what are the odds of creating a hospitable ecosystem by chance? Isn’t it more likely that our world is the work of an Intelligent Designer?
Well, if you want to play the ponies, yes. It is more likely. But it’s more like this: since we’re talking about infinity there, then yes, we’ll get intelligent life being created by blind chance. But this is intelligent life! If they’re half as curious as human beings are, they’re bound to think about the universe and run simulations. Even if there were an infinite number of universes with intelligent life, there is an even greater infinite number of simulated universes with simulated intelligent life.
What makes us so special? We’re just particles. Sluggish bio-computers that obey our input and our programming as dutifully as the spellchecker in Microsoft Word. We might observe that we have free will but we also “observe” that the washing machine has a mind of its own when it’s malfunctioning.
In short, I love the theories of infinite universes. Listen to the podcasts I linked to, they do these topics a magnitude more justice than my ramblings ever could.
