Why Materialism is Unscientific

Why Materialism is Unscientific February 10, 2011

You’ve probably heard the old question: Why is there something rather than nothing?  It’s unfortunate when theists screw this up.  They say: Because God created the universe!  Of course, since God is something, you can’t use God to answer the question.  The universe coming from God is just something from something.

And it’s doubly unfortunate when scientific atheists screw this up.  As a precautionary tale, here’s a recent example. Over at Starts With A Bang, Ethan Siegel wonders whether you can get something for nothing.   He writes:

In physics, can you get something for nothing? And if so, what can you and can’t you get? In many ways, yes, you can.  In fact, in many ways, getting something when you have nothing is unavoidable! (Although you can’t necessarily get anything you want.)  For example, take a box and empty it, so that all you’ve got is some totally empty space, like above. An ideal, perfect, empty vacuum.  Now, what’s in that box?  Did you guess nothing? Well, it turns out that empty space isn’t so empty.

Huh?  Apparently, if you guess that nothing is in the box, then you’re wrong – there really is something in the box.  Of course, there are no material things in the box.  But there is a “force due to empty space itself”.  More generally, the box is filled with all sorts of energy.  He continues:

And if you start with enough energy, you can take all of the real matter and antimatter pairs that exist, and create more matter than antimatter, giving us a Universe where we have something, today, rather than nothing. Now, that’s what we know we can get, even from nothing.

That’s absurd.  Here’s what we’ve been told so far: (1) space is filled with energy; (2) space has the power of exerting a force.  And surely anyone with a bit of physics education could continue: (3) space has at least three dimensions.  How then, could it possibly be nothing?  If it were nothing, it wouldn’t exist.  So it wouldn’t have any dimensions, it wouldn’t have any powers to exert any forces, and it wouldn’t be filled with energy.

If you want to do a bit more physics, and move from space to space-time, you’ll of course acknowledge that space-time exists and that it has lots and lots of properties, powers, and contents.  It has intrinsic curvature, it supports gravitational and electromagnetic fields, it perhaps supports various scalar fields, it has many dimensions, etcetera.

Surely Siegel agrees that space-time exists.  And if it exists, then it isn’t nothing – it’s something.  A few commentators picked up this point – good for them.

I think the real problem here is an assumed materialism: the only things that exist are material things (particles, atoms, molecules, etc.).  If something isn’t material, then it doesn’t exist.  That’s just silly.  Our best current physical theories involve all sorts of non-material objects – space-time being just one of many examples.   So, if you think our best physical theories are correct, then you can’t be a materialist.

This much can indeed be done by logic alone: Why is there something rather than nothing?  Because some things exist necessarily.  They can’t not exist – it’s not possible for them to not be.  So why are there some contingent things rather than no contingent things?  Contingent things are things that might be or might not be.  The answer to that question is:  Because the necessary things somehow entail the existence of the contingent things.

As expected, theists want to say that God is a necessary being and that the essential nature of God entails the existence of contingent things.  Atheist want to deny this.  And they might be right: there might be all sorts of necessary beings that aren’t gods.
