I want to understand quantum physics better. If nature at its deeper levels is undulatory and fluctuating, doesn’t this mean that there is no definite nature to something? Not that there is not truly a dog or a cat, but is it the same dog or cat everyday? This applies to us Catholics because we believe that relics are important.

You may want to discuss this on a physics forum. I don’t think the findings of quantum physics imply what you think they do. The fluctuations appear to be related to whether a particle is existing as itself or, at some other point, as merely a wave in something larger which includes the apparatus that isolates and demonstrates its properties. What I’m saying basically is that it shows the workings of matter to be the opposite of what you are saying here. But, I’m not a physicist and have enough trouble keeping up to date in my area.

I used to have a cat. Now it lives with my fathers. When I first knew it, it was so small that I could held it in one of my palms. It changed everyday! But I recognized it and it recognized me. It developed certain habits, and it keeps those habits after some years. If I tell you that it is the same cat that I knew years ago, this is what I mean. When I see it again, it responds to my calling and does the same kind of things it did before. It is the same cat, though it has changed.

The books I have are the same they used to be years ago, because I find the same texts I read in them the first time I read them. It is true that now they are brownish, and they became a little bit brittle. They have changed and I know it; still, they are the same.

Perhaps both my cat and my books are undulating things, but still they are the same to me because they preserve certain structure; an structure that I am able to perceive.

I don’t know what do you expect from relics, but I think that if they are able to satisfy your expectations, they do it no matter how undulating they can be, just as my cat and my books satisfy mine, even though they might be very undulating things.

There’s a good book by Brian Cox, the British pop physicist (although I’d presume he’d baulk at the term): amazon.com/Quantum-Universe-Everything-that-happen-ebook/dp/B005PVLGIE

Good if you have no background in the subject but are interested in learning more.

Nature is awesome, just as the Creator made it.

While there may be undulation and fluctuations (uncertainty), the essence of matter and energy remain.
 
Well from what I understand about physics, subatomic particles come and go out of existence all the time. Who knows if they are the same particles or not. So I am basically wondering if Catholics are required to believe that relics always have the same atomic particles, because otherwise it is not really materially related to a saint :confused:

Why do you think the physical makeup of a relic is of any consequence to its use as a sacramental? It has no power in and of itself. Do any of those subatomic comings and goings have any impact on what a material object is?

If it is not really the fingernail of the saint, why would it still be a relic? :confused:
 
If all the matter of the finger nail is gone and there are new subatomic particles in its place, it wouldn’t be the same fingernail

Conservation laws still apply. If one proton is replaced with another proton with the same position, momentum, angular momentum, etc., no conservation law is violated, and furthermore no one can tell the difference. So some essence remains intact.

Here is an a non-quantum analogy: About 60 percent of your body is water. As you consume food and drink, new water comes into your body to replace water that leaves your body by various routes of evaporation and excretion. In a week, half of the water in your body will be replaced. In a year, practically all the water in your body, the majority of your body mass, will not be the same water. A lot of your protein, lipid, salts, and other stuff is also replaced. In a year, most of your blood is replaced. But it’s still you, right? Your matter has been swapped, but your essence remains intact.
 
A person is a person because of the soul, even though the body changes. The relic is the relic not because of a soul. With new subatomic particles it would be a new piece of matter. The solution I guess would be that God would simply ensure that the new particles never replace old ones in relics. Otherwise, what would a relic even be at that point??

Your understanding, which I believe is incorrect or at least incomplete, seems to be that the essence of a relic is in its particles. There is more to an object than its particles. Its structure, that is, the connections, forces, and interactions between particles, would be at least as important, and that remains unchanged even if the particles are replaced.
 
I disagree. Something material is obviously made up of the material it is made up of. It can be rearranged perhaps to a point where it has a new form, but if the matter is different it is not the same piece of material

It would not matter if the particles are rearranged or changed. If we perceive that it is a relic, and we venerate that relic because of our faith, then God honors our perception for the sake of our faith. God can affect changes in material. The bread becomes the Body, the wine becomes the Blood. Jesus was alive, then He was dead, then He was alive. Everything changes. The only thing that remains the same is God.
 
Hello thinkandmull. I am currently studying for a PhD in particle theory, so I think I can help you out.

A lot of people have the idea that QM is a magical idea that makes nature unknowable. That technically isn’t true; at the fundamental level, QM is a very thinly disguised theory of linear algebra. Particles have wave-like properties, but fundamentally, they are governed by algebraic properties that restrict their structure to a few configurations, known as eigenfunctions. The uncertainty between position and momentum certainly exists, but they are simply the result of the inability of the position and momentum matrices to be simultaneously diagonalized. What this means is that certain values of these particles cannot be measured with 100% certainty at the same time, but we can know how these particles act on a macroscopic scale.

As for your point about particles appearing and disappearing at will, this is a facet of the theory of quantum fields, or QFT. QFT is quite a bit more complicated than quantum mechanics, so I won’t go into it here; basically, the particles that disappear and reappear are called “virtual” particles, and aren’t really what we consider particles at all. They are merely (in some interpretations) mathematical crutches that arise from the difficulty in solving the equations of motion of particles in this quantum field. Think of them like ripples in the quantum field. However, their behavior is well understood and there is nothing unknown about why they are there.

I’m glad you are thinking about the philosophical implications of QM (many physicists don’t even want to think about them 😃 ) But there is no conflict between QM and Catholic spirituality. Relics may be filled with virtual particles which have fundamental uncertainty, but the essence of the Relics is there all the same

John Polkington has written a few books on the subject of physics. He is both a physicist and a priest, so he has a firm grasp on both theology and the physical sciences.

Have a glance at these titles:

I’m thinking about how in the Eucharest, Jesus is present in the smallest element of bread. I wish I had a picture to demonstrate what I am getting at, but I may be wrong to assert that there is a smallest piece of bread, yet I think that is correct. Take the smallest piece as a circle or geometric pizza. All of these circles make up the host but Jesus is present under each one. But where is his body parts within the geometric pizza? I think we have to say one part has the reality of His arm under it, and so on. I know I went off on a tangent but the question about QM was answered well already and I was considering whether there can be a smallest piece of bread.

It is not evident that the comings and goings of the subatomic particles would actually result in the change that you are describing. What evidence is there the atoms are replaced in this process?
 
from what Fixed_Gauge said in his post, there is controversy in this area
