Causality and the Universe

A commenter by the name of Don felt left this comment on an old post I wrote ‘This Is How The Universe Happened, It Wasn’t Magic‘, attempting to refute the scientific logic with the below logic. I replied to him, and wanted to turn it into a full-blown post for two reasons. First to communicate the latest research in science, and secondly, because I spent a lot of time writing it, and this is now my fiftieth post, yahoo! (is that three?) Continuing on, this misunderstanding is the clearest instigator of deistic and theistic belief (which is not in itself bad, but believing in something because you don’t understand something else is probably never a good reason). His comment has been corrected for spelling errors (which were quite rampant), otherwise it was left as is.

What if Nothing Never Existed?

Nothing

What is nothing, and where did the something that we are and see all around us, come from? These are questions asked since our humble beginnings. Through the magic of modern-science, answers are finally being wrested out of the ether of space and time, and into something approximating language. Let us begin firstly, with a scientific controversy in 2012 relating to this very notion: the reception to the book, A Universe from Nothing, by the astrophysicist Lawrence Krauss.

There was a firestorm in some parts of the philosophic—and most certainly all parts of the theological—community due to Lawrence’s book, where he explained the latest theories in Physics. The crux of the storm rested upon the assertion that Lawrence made in regard to the nothing that a Universe can be born from, the Quantum Field (derived from Quantum Field Theory), which is as close to nothing as we have we ever arrived—and maybe ever will. Soon after its publication, the philosopher of science and theoretical physicist David Albert, wrote a scathing review of the book on the New York Times alleging that Lawrence was misleading everyone because his book never addressed the basic question of how a Universe was born of nothing, because the Quantum Field is something, even if it isn’t comprised of matter or energy, and that the book does not mention where those fields came from.

But what if the nothing that we demand explanation of, to explain our origins, never actually existed? That is, a region devoid of fields, physical laws, matter, anti-matter, the Higgs boson, and everything else (presumably including God since by this definition, He is something). What if semantics is the only thing being argued?

Maybe ‘nothing’ doesn’t, and never did, exist, and there has always been something, one-way or the other. 

The history of modern-science has come with it, at every step, the uncomfortable notion that we have been wrong about almost everything we’ve had an opinion on, especially those things that are orders of magnitudes bigger or smaller than us, and even many times, that which is on our scale. What makes the notion of ‘nothing’ any different? Below are some ancient and modern common-sense world views that met the cruel fate of greater understanding: 

  • We are intelligently designed
  • The world is flat 
  • Stars are holes in heaven’s floor
  • Earth is the center of the Universe and Solar System
  • The aether permeates space
  • Time is an absolute function of the universe
  • The very small (atoms) obey the same laws as the very large (galaxies)
  • Matter is solid
  • Space is a vacuum

 Our notion of nothing, to me at least, seems no different. It has been recently shown in this strange Universe we live in, by such astrophysicists’ as Lawrence et al, in doing a rather ambitious experiment found that the total amount of energy in the Universe is zero. That is, the amount of positive energy (matter) is exactly cancelled out by the amount of negative energy (gravity), and they both add up to zero. This question, seemingly, is no longer philosophical at its premise, and as Lawrence himself says, “Nothing is inherently unstable.

One of the first Greek philosophers, Parmenides wrote, “It is,” a statement in regard to the cosmos, or to anything you can think of. And to pre-existence, or nothing as, “It is not.” However, the latter statement is self-contradictory. To say “It is not,” is to say, “It is,” for you’ve contradicted that it is not, because you can think it in your mind (and we can’t actually think of nothing), and if nothing exists, it’s not nothing, but something. Or put more simply, “nothing comes from nothing.” From this, he takes the conclusion, one that I ascribe too, that there has always been something, in one form or the other. Today our best (though incomplete) theories suggest the Quantum Field is at the bottom of it all. Maybe that’s right, and I’m inclined to agree (not that my preference counts), or maybe it will be something else deeper down, but it seems absurd to suggest, or demand, that for a theory to be ontologically relevant, it must explain why there is not nothing. We have only one Universe, which came from a singularity (neither of which is nothing), which gives us a sample of one something, and zero nothings. No matter which way, or how deep, or far any theory goes, it will always be possible to probe one level deeper and say why this and not that? But just asking that question does not give it validity. This is not too say that it should not be disputed, or challenged, for this is where science thrives, but we must understand that our language muddles the issue here: the very word ‘nothing’ has no intrinsic meaning, nor is there anywhere in the Universe where there is truly nothing. Maybe by that admission alone, we’ll never know, but there’s even less fun in that.
