Mom, Cancer, Serendipity, and God

My mother has stage 3 pancreatic cancer.  She will soon leave this earth, but while her body is quickly fading, her mind and spirit are still there.  When she laughs, the twinkle in her eye is still hers.  She’s still there, and my family (and extended God-family) and I are relishing our remaining time with her.

We treated her to several days at Ocean City, Maryland, where we rented a penthouse condo overlooking the boardwalk, shops, and Atlantic Ocean below.  One evening, my sister and I put together a slide show to reminisce about past laughs, adventures, and tender moments.  In the middle of it, we were interrupted by a magnificent fireworks display – the kind you’d see on the 4th of July in a medium-sized city – exploding above the beach directly in front of us and at exactly our altitude.  It was almost as if the display, which serendipitously began in the middle of an emotion-packed slide show, had been intentionally perfectly centered in our line of sight as we gazed out over the vast ocean.

My initial thought was: was this an amazing coincidence or actually God’s hand?  It happened on Monday, July 8.  It’s hard to explain why the fireworks would have happened at that exact location and in the middle of our slide show four days after the 4th of July.  Obviously, far more impressive coincidences happen all the time.  Still, I think that God can and does intervene in the physical world.  However, given that God created the laws of physics – and has good reason to respect his own creation – then let’s assume that God’s power to meddle with the physical world is limited to “highly amplified quantum events” (HAQEs).  In other words, if God had actually intended to create an emotionally meaningful fireworks display to augment our slide show, then it would have been via the process of taking advantage of quantum events that get magnified chaotically to macroscopic outcomes; it would not have been via the process of unilaterally inserting fireworks into the beach, lighting them, etc.

By the way, physicists who take seriously the possibility of human free will usually make use of HAQEs (albeit with different terminology), since the ability to choose the outcome of a single quantum event (or even when a quantum event “collapses” into an outcome) can allow for free will without necessarily violating any known laws of physics. 

So let’s assume that God can manipulate quantum objects within the bounds of known physics – i.e., God can cause quantum collapse events and can choose the outcomes to the extent of their possibilities.  Here’s my question: could God have caused the fireworks display to happen at that exact place and precisely when we were doing the slide show?

Here’s a potential scenario to further elucidate the problem.  The fireworks themselves have to be planned well in advance: they have to be purchased and received; the pyrotechnics people must be hired for a particular day; the beach must be cleared; the fireworks must be mounted and connected to a control panel; and so forth.  Each one of these macroscopic events could have been (and to some extent probably was) ultimately caused by a HAQE, but how far back in time would we have to go to find the “source” HAQE for each of these macroscopic events?  For instance, perhaps it was the Mayor of Ocean City who determines exactly when the 4th-of-July fireworks are set off, and perhaps she was particularly concerned about bad weather.  Weather is the quintessential example of chaotic amplifications of quantum events – indeed, the well-known “butterfly effect” is an example of how a butterfly’s wings can affect weather!  God could easily have invoked HAQEs to cause thunderstorms on all the nights leading up the 8th, at which point the frustrated mayor would have decided it was finally time to light up the belated Independence Day display.

So, anyway, it’s an interesting physics question about the extent to which divine events or miracles are within the scope of the known laws of physics, a question that I will continue to ponder in the coming years.

And that’s what I initially pondered at the moment which was, as you recall, when a fireworks display interrupted a slide show tribute to my Mom.  Coincidence or not, there was a certain divine magic to it. 

I sat next to her and held her hand – the bony hand of a quickly decaying body – as we watched a loud, obnoxious, beautiful display that very well may have been meant for our eyes.  I felt overwhelmed by the absurdity of the situation, the sadness I felt, the depth of meaning and emotion I was experiencing.  I felt an intense gratitude for the opportunity to experience such love for and from this woman, a silly giddiness at how simple everything seemed in that moment.  I felt intense pain and intense joy at the same time.  I squeezed her hand and sobbed deeply.

On one hand, how tragic that I would soon no longer taste her homemade cheesecake or hear one of her terrible jokes in which she starts laughing before reaching the punchline.  On the other hand, how wonderful that her cheesecakes and terrible jokes have brought me so much happiness in the past.  How dare God take this woman away from me.  Then again, as overwhelmingly sad as I feel, thank God for giving me a Mom whose loss would make me feel so overwhelmingly sad. 

Out of my joy is born sorrow, and vice versa.

The Physics of Free Will

I know the topic of free will has been debated endlessly for millennia, and everyone has their own opinion.  However, I’ve read and searched endlessly, and I can’t find anyone who addresses or answers the following problem.

Let’s say that I perceive that I have the choice to press button A or B.  There are only three possibilities:
a) There is no actual branching event.  The perception is an illusion.  The button I press is entirely predetermined.  (That doesn’t imply that the universe as a whole is deterministic, but that indeterminacy is irrelevant to my perception of a free choice.)
b) There is a branching event, but it is quantum mechanical in nature.  In other words, the button I press actually depends on some QM event (whether you call it measurement, reduction, or collapse), so while the outcome is not predetermined, it is random.  The perception that a branching event was about to happen was correct, but the perception that I can control it is an illusion.
c) There is a branching event, and my free will caused the outcome.

In case a), my “choice” is simply a prediction about the future.  But there are several problems with this:
1) Why would I ever perceive as possible an event that is actually impossible?  (If pressing button A was predetermined, then pressing B is an impossible event.)
2) What is the advantage of making a prediction if awareness of the predicted outcome will not affect anything that will happen in the future?  In other words, if I can’t DO anything to change anything (because I don’t have free will), what’s the point in predicting? 
3) What is the advantage of perceiving free will when I am actually making a prediction?  When I drop a ball, I predict it will accelerate downward toward the Earth.  But imagine if I (falsely) believed I had free will over that ball... “OK, am I going to drop the ball UP or DOWN?  Hmmm... today I’ll decide to drop it DOWN.”  What would be the point of that false perception? 

The case of b) isn’t much better, because my “choice” is, again, just a prediction about the future (possibly coupled with measurement of a random QM event).  The same problems arise.

Note that my perception of free will is limited to my body, and not even my entire body (for example, I don’t think I can consciously control my digestion process).  In fact, I only perceive “free will” with regard to a few aspects of my body, such as motions of my hands and fingers.  But what is true is that I have never EVER once observed the experience of NOT having free will over those parts.  For example, I have never decided to raise my right hand, but then my left hand rises instead.  I never raise my hand and then say, “I didn’t do that!” 

But that COULD have been the case.  I could have been born into a world in which I just observed things happening... where my body was no different from a dropping ball or a planet orbiting a star... where it’s just an object that moves on its own and I experience it.  In other words, why am I not just experiencing the world through a body that moves on its own as if I were just watching an immersive (five-sense) movie?  It’s not like we need to believe in free will.  For example, we are perfectly fine watching movies or riding roller coasters, full well knowing that we can’t control them.  Why couldn’t we just be passing through the world moment-to-moment, just experiencing the ride, without any perception that we have free choices?  In other words, if a) or b) above is true, we need to explain WHY I perceive the freedom to press button A or B, but also why my choices are always 100% consistent with the outcome.

That’s a real problem.  Because now we have to explain why the universe would conspire to:
* Fool me into believing that I have a choice when I don’t; AND
* Fool me into believing that the outcome is always consistent with what I (mistakenly) thought I chose!

Why would the universe fool us like that? 

As an aside, please don’t answer with “compatibilism,” which is the philosopher’s way of avoiding the question of free will.  You can look it up, but I regard it as a non-answer.  Even famed philosopher JohnSearle agrees that philosophers haven’t made any progress on the free will question in the past hundred years.
