Across the Multiverse

A thought occurred to me the other day while show­er­ing — which is where all my best ideas strike — that if a par­al­lel uni­verse exists for every choice I make and every choice you make, then it is the­o­ret­i­cally impos­si­ble for me to cross over into another uni­verse. The sim­ple act of cross­ing over into another uni­verse would make that uni­verse the uni­verse that I live in, thus no longer exist­ing as an “alter­nate” uni­verse, but it would become my prime universe.

I men­tioned this the other day and some­one sug­gested that if uni­verses were lanes on a high­way, then when we change lanes we don’t take the other lane with us. This quickly brought me to the real­iza­tion that if the Multiverse exists, then it only exists in the wake of our exis­tence, that is the exis­tence of each of us in our own reality.

I use the word wake inten­tion­ally because our exis­tence leaves a mark that can be felt by those in close prox­im­ity to us, but over time fades out and, even­tu­ally, can no longer be felt. If my wake passes through your wake, it changes the cur­rent of space-time and cre­ates cross cur­rents. Heraclitus said “You could not step twice into the same river; for other waters are ever flow­ing on to you.” He sounds like a Buddhist.

The idea of par­al­lel uni­verses has always been one that intrigued me; I loved watch­ing Sliders when I was younger (can you say Sabrina Lloyd?). But it’s impos­si­ble, now, for me to con­ceive of some­thing so arro­gant as a Multiverse — William James must have loved him­self immensely. To think that a whole entire uni­verse is cre­ated (or exists) for every choice we have made or will ever make is pre­pos­ter­ous. It’s on the level of cre­at­ing gods to pro­tect us from our fear of exis­tence as irrel­e­vant and mean­ing­less, or to preach that non-terrestrial life forms are mere sci­ence fic­tion, when our very exis­tence on this planet is proof enough of the possibility.

So, with these thoughts I leave you for debate on the issue and these words from one of the wis­est men who ever drew his wis­dom from the com­mons: “This uni­verse, which is the same for all, has not been made by any god or man, but it always has been, is, and will be an ever-living fire, kin­dling itself by reg­u­lar mea­sures and going out by reg­u­lar measures.”

  1. I’ll admit it: I came to check this out mainly for talk about par­al­lel uni­verses. I’m a sucker for big-picture cosmology-talk.

    I don’t dis­agree with any­thing you’re say­ing here, because par­al­lel uni­verses are a pretty odd thing to have a con­crete opin­ion about (and my opin­ions tend to be pretty squishy at the best of times), but think about this: imag­in­ing an alter­nate uni­verse for every pos­si­ble human deci­sion is, yes, com­pletely arro­gant, irra­tional, and anthro­pocen­tric. But what if there’s a dif­fer­ent uni­verse for every pos­si­ble quan­tum state — not just human choices, but those ‘ran­dom’ par­ti­cle inter­ac­tions that seem to both hap­pen and not hap­pen? It gets a whole lot harder to think about, but at the same time, more plausible.

    If you’re into big, brick-like spec­u­la­tive fic­tion books, I rec­om­mend one called Anathem, by Neal Stephenson. This whole deal (par­tic­u­larly the idea of ‘wakes’ and ‘cross­ing cur­rents’) is a pretty major theme.

  2. I’d love to hear about it some time. I might do some inde­pen­dent research in the meantime.

  3. Sliders was my jam.

  4. Based on your meta­phys­i­cal mus­ings, I assume you engage in the age-old prac­tice of ‘a bong hit before the shower’. Or you’re just a more pro­found per­son than me with­out the assis­tance of narcotics.

    Great post. I must admit that I googled Sabrina Lloyd and found her less than stel­lar. Am I miss­ing something?
