Philosopher and photographer Laszlo Bencze was complaining to us recently,
The real problem with infinity as I have come to realize is not the mathematics and logic of it. Rather it’s that just about everybody has a firm opinion on the topic. Yes they do. Average people who haven’t cracked a math text since they failed Algebra I, know exactly what infinity means, how it functions, and how it is the answer to many perplexing questions. They KNOW that actual infinities exist and no amount of reasoning can argue them out of their certainty. Yes, I’ve tried. They regard all explaining as mere trickery. Furthermore, they KNOW that our universe is infinite, time is infinite, energy is infinite, and that the potential of people is infinite. Are you tempted to have a pleasant discussion with them at Starbucks about any of this? Don’t bother. They won’t listen and your discussion will turn into an unpleasant conflict with high odds of ending whatever budding friendship you may have had that person. You have been warned.
But multimedia guy Art Battson replied,
Don’t throw away that gift card to Starbucks quite yet.
If someone tries to convince you that an actual infinite of anything physical exists tell them how brilliant they are and how you plan to create an infinite number of universes. It’s actually quite easy. Take one universe and divide it by zero. Now that they have an infinite number of universes where anything and everything can happen, it follows that there is at least one universe (and it can be argued that there are an infinite number of universes) where the Chicago Cubs have won each and every World Series.
Assuming they are not from Chicago, they will readily admit the absurdity of their belief.
Now buy them that cup of coffee.
The discussion turned to a book by science writer Charles Seife, Zero: The Biography of a Dangerous Idea, (2000) wherein zero is presented as infinity’s twin.
And wherein it is shown that dividing by zero shows that Winton Churchill was a carrot.
But that’s perfect for multiverse thinking!
Okay, back to work really soon. Meanwhile,
