ULTIMATE REALITY AND THE MEANING OF LIFE – MATTER – PART III (continued)

Last time we looked at the composition of solid bodies as one version of ultimate reality ending on the elementary particles that form the building blocks of matter. While they fit into two basic groups -quarks and leptons – there are a multitude of these elementary particles. Thankfully only a small number are constituents of the chemical elements that fashion most of our material world. These ‘particles of construction’ include electrons, photons, u quarks, d quarks, gluons, and gravitons. The electrons carry a negative charge, but little mass. The photons create the field that keeps the electrons attached to the nucleus. The u quarks and d quarks combine to create the protons and neutrons that make up the nucleus with the gluons as the ‘glue.’ Gravitons create the gravitational field through their great number and ‘spin.’3

Of course subatomic physics is much more complex with additional ‘particles of change’ such as W and Z bosons, Higgs bosons, and neutrinos; and ‘bonus particles’ such as c and t quarks, muons, and tauons. Dark matter is also likely some form of elementary particles. So far there are more than 300 known particles, some existing naturally, others found only with the help of atom smashers called particle accelerators. But one thing that unites them with all within the cosmos are the four fundamental forces: gravitation (the weakest of all, but responsible for the celestial mechanics), electromagnetism (which holds atoms together), the weak force (which causes particles to decay into more stable pieces of matter), and the strong force (which binds the nucleus together). This picture of the elementary particles and the four fundamental forces is known as the Standard Model.4

Unfortunately I will have to stop there without exploring designer particles, holes, quasiparticles, the fractional quantum Hall effect, etc., all of which is way beyond my simple understanding. Instead I would like to move now to the philosophical implications of ultimate reality as the elementary particles and the four forces. It seems to me this is the most physicalist presentation of all and likewise the least satisfying. The number of particles is unaesthetically large; the means to identify most of them (particle colliders) is utterly unnatural; and the instability and ultrashort duration of most of them hints at a kind of artificiality. Certainly the theory of a material world constructed from a myriad of combinations of atoms of the 118 mostly stable elements listed on the periodic table is more palatable and more relatable as ultimate reality, even if less complete.

It is therefore not surprisingly that physicists have postulated a simpler and more unified theory of the material world which is the subject of our next meeting.

  1. As always, interesting material and information. Matter is a component of reality, here, present and in our faces. We are made of water, flesh, blood, bone and so on down to the very small…quantum things. Are we, then, part of ultimate reality or is it part of us? I have read some of what panpsychism claims, or what some adherents say about it anyway. It is mysterious to me, to say the least. I wonder what you think about panpsychism. And whether it is part of ultimate reality? Or is that just another way of discussing mystery?

    1. Paul,

      Thanks for following along.
      Yes I think that is the direction we are headed in – how is ultimate reality related to us? Are we part of it, or does it come from or through us, or are we identical to it? Or are we separate by nature or if separate can we interact or even unite with it.
      I am not sure of the answer of course, though I hope to get closer in this section.

      And yes I intend to take on panpsychism when I get to the latter part this segment on matter and the universe as one understanding of ultimate reality. I hope to address whether there may be a consciousness coming from the workings of the universe or whether it is possible that all parts of the universe have a type of consciousness. Stay tuned, but in the meantime, I would love to hear what you may have uncovered on this topic.

      Regards,

      Greg
