A Conclusion to a Still Unwritten Book: The End?

I previously have suggested that the universe seems to have been designed and that this therefore implies a designer. Following this supposition further leads to two fundamental questions: where did the designer come from and why might it have designed and launched the universe we inhabit. Subsidiary questions might include what materials and tools did the designer use and what can be said of the designer? We might also wonder if the designer watches or cares for us or has any of the other attributes humans have often associated with their gods such as being infinitely powerful, wise, kind, all knowing, loving, good etc?

Before taking a stab at these questions, it is worth noting that physicists and cosmologists are also trying to peer behind the curtain of creation. String theorists are still seeking – despite a lack of any experimental evidence offered by current high energy physics – to reconcile relativity and quantum physics and thereby explain the menagerie of observed elementary particles and forces. Recently, they have found a set of one quadrillion possible solutions to string equations within a ten-dimensional spacetime that have “the same set of matter particles as exists in our universe.” But there remains no experimental evidence or process for deciding which of these quadrillion, if any, may be applicable to the observed reality.

Also, for the past decade or so, cosmologists have been looking at alternatives to the inflationary scenario of the post-Big Bang universe. Inflation explains features of the cosmic background radiation. However, it does not explain from where the Big Bang itself arose beyond the suggestion that it came from some quantum fluctuation within a primordial singularity. An attractive alternative to having to explain any sort of a beginning is to assume that the Big Bang was simply our side of a “bounce” or “collision” between universes.

All these efforts to explain what might otherwise appear to be an amazing Goldilocks universe – in which all the elemental particles and forces seem to lead to the evolution of complexity and the seeming inevitability of life – must in the end still suppose something unexplained and just given: a multidimensional universe beyond ours, a singularity just sitting there at the beginning of time or a series of bouncing universes just following one another. (This latter leaves aside the issue of dark energy’s apparent speeding up of the expansion of our universe so that it never reverses into a big crunch. Instead, it seems that eventually – in some enormous 10 to the 100th years – matter will have broken down and even black holes will be warmer than space and radiate away with a final pop.)

It might also be worth pausing to wonder why the universe would have to be designed rather than simply “wished” into being as befitting an all-powerful “god.” Put another way, why would a creator need to design a universe using materials and processes that we would find understandable as laws of physics? Was the designer constrained in some way – perhaps by some preexisting Platonic Forms – to act through means such as singularities and Higgs fields?

Occam’s Razor suggests to me that we simply acknowledge that our universe seems to have a design discoverable by science and wonder about the designer. Following this line of inquiry, I return to considering where might have the designer come from and why might it have designed and launched the universe we inhabit?

It seems to me that there is no way to answer the where question. One must either posit that there never was an original moment of creation or accept that there was such a moment and recognize it as an uncaused first cause. Which came first, the chicken or the egg? Either the designer was caused – by what, from where? – or was itself the First Cause. This seems to me the unanswerable question behind all others and thus the essential mystery at the bottom of all science, religion and philosophy.

The why question may be somewhat more amenable. Consider that the universe does appear to have been designed and put into action according to the physical laws thereby built into it. Could it be a grand simulation to test theories of good and evil, a complex and especially vivid dream or simply a work of art? Might it be a majestic theater on which a countless number of actors play our parts and then disappear off stage thus making the designer a cosmic Shakespeare? Or might it have been set in motion for the consciousness behind the design to dump itself into to avoid an endless eternity of loneliness and thereby undergo an almost endless series of experiences acted through everyone and everything? I myself drift toward the last suggestion and to the possibility of a universe in which consciousness is primordial and attaches to everything with mass (a kind of panpsychism). Life would offer the most interesting existence. So perhaps the designer looks out through the being of everything, in a sense making us all “children of god?”

One last question, does love come into it at all. Does the designer love its creation or any part of it, such as us? If the cosmic consciousness is in everything, then it may be essentially a matter of self-love, even when we “love” one another. I believe we exist as individuals and we love as such. Our capability – indeed need – to love suggests it is somehow built into the design.

Gravity, Mass and Time

Recently finished physicist Kip Thorne's The Science of Interstellar about his work to make the movie as scientifically grounded as possible. While written for the interested layperson, some of it was hard to follow. But it provided a lot of food for ruminating about the deep connections between gravity, mass, time and the speed of light.

At the speed of light, time stops. Anything with mass that reached the speed of light also achieves infinite mass. (This is one good reason to believe that nothing with mass can go that fast. Anything of infinite mass would need a great deal of thrust to keep going, indeed, an infinite amount.) Photons have no mass and thus they gain no mass. Anything – some ghost without a machine – traveling with that photon at 186,000 MPS would also be timeless and thus everywhere that photon will ever be all at once.

Time also stops with an infinite mass that is not going anywhere, at a black hole. Gravity slows time. At the event horizon of a black hole, spacetime is so warped that nothing can escape upwards – not time, not space, not matter, not light – but falls down into the black hole until it reaches the singularity at the “bottom.” While the black hole may have a certain mass – the mass left over from the collapse of the star that formed it – the singularity itself has the equivalent of infinite mass. Anyone watching a friend drop into a black hole would never see him or her actually fall all the way past the event horizon. From the outside, the friend would be seen moving ever slower. At some point, a second to the falling friend might be, for example, a billion years to the outside observer.

Not just black holes slow time. Anything with mass does, including earth. Einstein's theory of relativity predicts this. And indeed, time on the GPS satellites (orbiting over 16 thousand miles up) run some 45,900 nano seconds slower per day than clocks on earth. The stronger the gravity, the slower time goes compared to places of less gravity.

Mass warps spacetime and achieves that effect through gravity. We don't understand where gravity comes from and it does not fit into the Standard Theory of quantum physics. Relativity seems to describe the effects of gravity but neither meshes with the Standard Theory nor explains from whence gravity comes. String theory has been the Standard Model's framework to incorporate relativity as quantum gravity. To do so, it would require extra dimensions beyond the four we observe (three space and time). But recent experiments have found no supporting evidence for the simplest forms of such theories.

It may be that mass, gravity, and time are just givens. Gravity is something that slows time. At the speed of light, time stops. Our experience of time – our consciousness – seems related to the speed of light. Mass keeps us from exceeding the speed of light. Random?

Light Music

Been reading Light Music, a 2002 sci-fi novel by Kathleen Goonan. Like most good science fiction, it takes some central bit of science or technology and extrapolates it. Light Music contemplates a juxtaposition between string theory and consciousness. Now string theory has taken some hits recently as analysis of the Higgs field seems to rule out the simpler, more elegant, versions of supersymetry. But Goonan paints a picture of consciousness, residing somewhere in the extra tiny dimensions postulated by supersymetry, as a kind of energy acting on the universe through matter as a kind of string vibration, a kind of music, as photons of light are vibrations of electro-magnetism. Thus Light Music. Very interesting speculations.

In this space, I've suggested that consciousness is primordial, that it does not rise from matter, or any particular organization of matter, but may indeed be prior. That consciousness – our individual experience of it – may be bound up with light, which is its “speed.” So picture consciousness as vibrations in (of?) spaces too small for us to observe – at or even smaller than the Planck length – intersecting the fields and particles of matter and energy we can measure and manifesting as observation. Yes, a “ghost” in the machine, taking the form of mind when the organic substrate is complex enough to give rise to such. Collapsing the wave function and exercising choice, self-generating music out of our individual being, a lifetime symphony.

Just another rumination.

The Higgs and Time

It's coming up on a year now since the confirmation of the Higgs particle and field. This was an exciting reaffirmation of the Standard Model of modern particle physics. But after a year of refining measurements, it seems the version of the Higgs found fits too well with the current model and offers no hint of any unexpected strangeness that could lead physicists to further insights and discoveries. The Higgs mass has been determined to be 125.7 GeV (gigaelectronvolts). Quite remarkable measurement but one that agrees so perfectly with the Standard Model that it leaves little room for current theories that tried to go beyond it to a more unified physics. Most varieties of supersymmetry and string theory – the simpler, more beautiful ones that physicists prefer – cannot meet the constraints imposed by the Higgs value. The current model cannot account for gravity or relativity and can't explain dark matter or dark energy. This means that while it can explain very well 5% of the universe, it cannot say a thing about the remaining 95%.

But it may be even more interesting to ponder the fact that the particle that gives other particles mass also has a mass. The Higgs field interacts with some particles (the quarks) and gives them mass while others (neutrinos and photons) are lightly or un-affected and have little or no mass. But if the Higgs interaction gives mass, what gives mass to the Higgs? This is another of the strange places that our modern science leads us. (Are you watching St. Thomas?)

Mass may also be at the root of time. Things with mass cannot travel at the speed of light and therefore exist immersed in time. Things without mass do travel at light speed and therefore are not subject to time. It's as if mass is really a measurement of the degree to which stuff is trapped in time, separated out of what would otherwise be an eternal now. Or to put it another way, introducing mass is a way to throw things out of heaven and down to earth?

Maybe Reality Is Not An Infinitely Peelable Onion?

Science is the search for rational understanding of nature and the universe achieved through replicable observation.  2012 has seen a fundamental advance in the effort to achieve an ultimate understanding of physical reality and the cosmos with the discovery of the Higgs boson.  In July, the Large Hadron Collider (LHC) in CERN found direct evidence of the Higgs.  Since then, further LHC data appears to place the Higgs more firmly in the Standard Theory that unifies three of the four fundamental forces (electromagnetic, weak, strong and gravity).  Perhaps equally significant, however, is what LHC seems not to be finding - evidence supporting Supersymmetry, the only candidate theory physics has to unify all four forces and explain the dark matter that seems key to holding galaxies together.

Supersymmetry posits an unseen partner particle for every particle now known to science.  Supersymmetry is a basis for string theory, which directly seeks to account for quantum gravity.  With evidence for supersymmetry and string theory, we would have a unified theory of forces and particles, uniting the big and the small and explaining "everything."

Trouble is that those particles that LHC could be finding if the simplest versions of supersymmetry were predictive don't seem to be there.  This does not rule out more complex versions of the approach but modern physics has generally been guided by the notion that the simple is most beautiful and the beautiful is more likely to be true.

But its not the details of the current state of physics that I want to talk about here but the very quest for an ultimate understanding, one that explains everything we can see and know by some set of fundamental scientific laws and equations.  The notion that everything has an ultimate explanation, according to a laws-based structure that puts everything in its place, cannot logically be true.  Any explanation of what is by another set of what-ises begs the question of what explains those.  Gödel’s Incompleteness Theorem puts this nicely:  “Anything you can draw a circle around cannot explain itself without referring to something outside the circle – something you have to assume but cannot prove.”

The menagerie of particles now known by science includes all sorts of particles with mass (fermions) and those without (bosons).  The smallest fermions include quarks and leptons.  Supersymmetry and string theory seek to explain all these particles by placing them within a frame with many other particles and dimensions that we cannot observe and for which we so far have no evidence.  Meanwhile, an extension of string theory - superstring theory - seeks to explain the Big Bang and space-time by positing other things we cannot observe:  colliding branes.

Let's suppose that we find evidence of some form of the supersymmetry and superstring theories, i.e., that they are "true."  What will explain them?  What will account for whatever laws and equations that seem to predict everything else we can observe?  Where do the laws that govern lawful action come from?  As Gödel proved, nothing can explain itself.

Perhaps, Plato was right.  The cosmos is made up of Forms.  What if the basic building blocks of existence - the bosons and fermions we observe, the structure of space-time, the Higgs field that creates mass, the gravity that pulls mass so tightly that it releases the energy of life in the middle of our sun - all these, just are? 

The explanation of everything is either infinitely recursive - each peel of the onion of explanation simply uncovers the next layer to be explained - or the ground of everything is/was simply there.  Either way, it makes science no less important and useful but not necessarily the answer to all questions and especially to those most human of all questions - why are we here, where do we come from and for what ends?
