Neutrinos: The Particles of Decay

I watched a fascinating documentary on Nova last night about neutrinos, and with my reading list consisting of books on subjects like chaos theory and entanglement theory I figured it couldn't hurt to brush up on basic particle physics.

According to the current model of science, matter is composed of atoms, which in turn, are composed of particles (such as protons, neutrons and electrons). While it was originally thought that these 3 basic particles were the only ones, science has shown evidence that they are not. These 3 particles are made up of other elementary or "fundamental" particles, which are either fermions (particles of matter), or bosons, some of which perform as carriers of forces of nature, such as the weak, strong and electromagnetic forces (a gravitron, which would be a carrier of the gravitational force, would be a boson, but it is still theoretical). Neutrinos are one such additional elementary particle.

One interesting characteristic of neutrinos is that they have the ability to pass through matter almost unhindered (which they do at a rate of something around 100 billion per second). Another feature of neutrinos, the one that originally caught my attention, is the fact that they are a product of the decay or breakdown of protons and electrons. Neutrinos were actually discovered when scientists began to search for the 'missing energy' when they were studying the properties of decay. Sources of neutrinos include nuclear explosions, the nuclear fusion process in stars, supernovas and the interaction of cosmic rays with the Earth's atmosphere. Neutrinos themselves cannot be detected, so what scientists study is their interactions.

It got me thinking....

According to the first Law Of the Conservation of Energy, matter cannot be created or destroyed...it can only be transformed. So, when anything DIES (decays/degenerates), there is at the very least something basic within it that is not destroyed, that perhaps goes on to become something else (like neutrinos, perhaps).I think that the knowledge and study of neutrinos (as well as other subtomic particles) can be very useful in obtaining further scientific explanations or explorations into death, and what's more, that perhaps in the future, physics and philosophy will be disciplines that are taken much more seriously relative to the other. We would be deriving a more complete knowledge from an integrated whole composed of the science of physical reality and the pursuit of wisdom. I think the two can compliment each other greatly.

It must be said here that physics is an interest of mine, and certainly not an expertise, so anyone with more knowledge on this, feel free to correct anything I've said that is incorrect.

Ok - another fabulous post. My interests have always leaned into the science side of things and one of the first few concepts to make me really ponder was the Conservation of Energy. Now that led me initally to eternalism but finally to an interpretation of the mind stream. [Insert fond memories of gr.10 science] :)

Josh...

I think that the Conservation of Energy Laws definitley point to some sort of eternalism...the eternalism of what is most 'basic' perhaps. This could fit in somehow with the whole question of "if there is no permanent soul" as Buddhists believe, "then what is it that reincarnates?" Ibut I haven't quite got my head wrapped around this yet LOL.

Really like the physics posts.

Great articles and posts. According to quantum mechanics the conservation of energy is violated. And also, Quantum mechanics is supposedly a "complete" description of reality. What interests me is...if it is complete, then is quantum mehcanics a reflection of the limits of the human mind, or is the theory incorrect to begin with.

Thanks for your comments.

Interesting. I am very curious as to how it violates these particular laws. :-)

You've also presented a good question. I think that if quantum mechanics is 1)correct and 2) complete it could very well provide a way for a thorough understanding and knowledge of mind while at the same time certainly showing us its limits. The mind is a useful tool for grasping physical reality, but certain truths and realities go beyond mind. Mind can only take us so far along paths of understanding...when we reach the entry gates of what's beyond, we must transcend mind to pass on to more complex levels of understanding. (Gate Gate Paragate Parasamgate Bodhi Svaha!)

But then again, I still don't know what I'm talking about.

Your response is to the tee!!!

You might have heard of the Hysenburg Uncertainty Principle. Where the more accurate you know the momentum of a particle the less accurate you know the position. Well... it is also true for energy and time. The more accurate you know the energy the less accurate you know the time interval. Anyhoo, the HUP is not a result of our experimental limitations but is actually a result of the wave nature of elementary particles!!!!I love saying it, hehe. So the point of it, is thier is an uncertainty in the energy. So you probably want to know where that energy goes.

The answer I believe is this. Quantum field theory, which only exists as a theory states that the electromagnetic force can be described by the movement of photons. Similar to gravity being described by the graviton. Soooo, the energy lost via the uncertainty principle is imparted to these photons.

But, quantum field theory only exists as a tool, not as a description of nature, so its sketchy, but its the way it is!!!

Hope thats clear. I personally believe quantum is missing something.

Heres a great analogy. You have five blind men and an elephant. If you ask them each to feel around the elephant and explain what they have sensed, they will each describe different parts...like the tail the head etc. However, do you think that together they can accurately describe the full elephant? Quantum is like that, it works, but it makes no sense because the bigger picture is lost.

Thats my blurb :)

Hey M, Dale

One thing that I think belongs to quantum physics that I find absolutely fabulous is that the only thing that we can truly prove is the observer. All things render within the observers view and by some experiments (feel free to fill in the references), the observer will affect how the results of a given inquiry goes based on the observers assumptions. For further elaboration, check out "What the Bleep Do We Know?". The commentary at the bottom of the link provided is worth reading.

M,
So far as I've been able to understand the thing that re-incarnatates:
At our very fundament, we are energy. To define terms here, energy is something that has a direction and magnitude. This would fit Dale's view. Energy is synonymous with karma. Our present form (feeling, perceptions ..) is the result of our past actions. As energy cannot be created nor destroyed; only changed form, we continue to take steps based on our previous energetic states. We mold and shape new worlds with our assumptions and concepts and the resulting mental and physical karma. Death, birth & rebirth are just ideas we wrap around the phenomena that just is. At this point in my argument I'm tending towards eternalism (one of the 2 extremes). Nihilism (the other extreme) would say that this energetic state would cease to exist at some point. Some critics of buddhism have pointed at nirvana as the extinguishment of self, mind-stream or soul - to much emotional turmoil. To some extent both are true - which is the middle path. The mind-stream continues in ignorance of it's manifestation until the time of it's complete awareness where One can choose the next step, energetic state, or karmic configuration for the benefit of all.

At my present 'energetic state' I probably have this all wrong :) But perhaps it helps someone.

Yeah definately. Every new form we take from moment to moment is a birth and death of energy governed by conservation.

About the observer perspective in quantum mechanics. It has been a huge question mark of quantum mechanics to explain the nature of particles before an observation is conducted. I mean, how can something exist in different forms and states in different places at the same time?

I definately do not know how!!!But my rational dualistic self can not understand something that is incomprehensible on the ego level. Hehe.

I have heard of the HUP. Another one of those 'laws' that has intrigued me. If I'm correct, then something can either behave like a wave or a particle, but not both. Light is an exception because it acts like both a wave and a particle, depending on the circumstance, Are you saying that all elementary particles can be both wave and particle? If so...this goes along quite nicely with the BOTH/AND thing I've been talking about. My understanding of quantum physics (although I LOVE it) is kind of basic so i dont even know if i am making sense or not.

You said "electromagnetic force can be described by the movement of photons...Soooo, the energy lost via the uncertainty principle is imparted to these photons."
So in other words, quantum theory claims that the unaccounted for lost energy has been absorbed (?) by light (and perhaps not by neutrinos?)

Intriguing...does the electromagnetic force neccesarily have be the movement of photons?

Thanks for pointing all this out. And I am in agreement that something does seem to be missing. I really need to be more familiar with this subject matter. Do you think that a theory of quantum physics will ever be able to explain things on a large scale as well as it does on a small scale?

Thanks for your input. :-)

Its great to see people take an interest in physics.

I dont actually know why its specifically photons. Might be because its energy, which is specific to a photon exactly fits the uncertainty in the HUP.

In fact, everything is a wave, according to quantum mechanics (QM) even you are a wave, but because your mass is so great the wavelength is exxxxxtreeemely ssmall, so you cant notice them on a macroscopic scale.

If we accept QM has begin correct, then before we make an observation the particle exists as both a wave and a particle at the same time, and then when you make the observation it chooses one!!!Its as if the particle has consciesness and knows what state to change into based on the situation.

If you are more intrigued then my shabby explanation then look at youngs double slit experiment. Its very interesting.

Bye for now!!!!

Josh...

VERY well said (on the observer). If you check my profile you will see that What The Bleep Do We Know" is one of my favourite movies. Thanks for the link!

And as to the rest of what you said, I don't think you're wrong at all. In fact, I couldn't have summed this up better myself. Very succinctly said...I am in 100% agreement. Deserves a reprint..."As energy cannot be created nor destroyed; only changed form, we continue to take steps based on our previous energetic states. We mold and shape new worlds with our assumptions and concepts and the resulting mental and physical karma. Death, birth & rebirth are just ideas we wrap around the phenomena that just is."

Dale...

My rational dualistic self can't understand something that is incomprehensible on the ego level either, but there's just something about it (the possibility of existing in two places at the same time) that resonates with me...somehow it feels correct. But then, I never claimed to be completely rational (not even close LOL)


I am enjoying this immensely. Thanks guys!

Hey M,

I found something related but kinda tangenty. It's about the illusion of time and I figured since physics has a lot of assumed time in it this would be a good place. Check here for the text.

Later,
Josh

How synchronous, Josh...

I was just working on a new post...on TIME...

Thank you very much for the link...it will come in handy :-)
