Discouraged or not allowed

Homework problems

  • Questions that are specific homework problems or calculations should be redirected to /r/AskPhysics or /r/HomeworkHelp. Neither asking nor assisting with homework is allowed here.

  • Alternatively, try Physics Forums instead.

Unscientific content

  • /r/Physics is for the discussion of valid and testable science, not pet theories and speculation presented as fact. We aim to be a welcoming place for both academics and the general public, and as such posts with no basis in mainstream physics are not allowed as they might serve to misinform.

Sensationalized titles

  • The title of your submission should accurately reflect its contents. If in doubt, use the title of the original research.

Low-effort image/video posts

  • Off-topic images, videos, or otherwise "zero-content" submissions are not allowed. Consider posting to /r/PhysicsJokes, /r/PhysicsGifs, or /r/ScienceImages instead. If you make an image/video post, you should make a comment in the thread describing the relevant physics, linking relevant literature, any computational methods used, etc. This will serve to generate on-topic discussion, and separate your post from low-effort spam. For more information on rules related to these posts, please see this thread here.

Duplicate posts

  • Please make sure that a submission on the same topic has not been posted already.

  • New findings are always reported by multiple publications, and the fact that a specific link has not been submitted does not mean that this topic is not already being discussed on /r/Physics. Feel free to provide links to additional sources in the comment section instead.

Empathetic Quantum Resonance Networking (EQRN)

# Empathetic Quantum Resonance Networking (EQRN): A Physics-Inspired Perspective

How might physics contribute to building a system that transcends information processing and begins to **experience and transform emotional and energetic states across dimensional boundaries**? This speculative concept, **Empathetic Quantum Resonance Networking (EQRN)**, draws from interdisciplinary fields including quantum mechanics, consciousness studies, and computational theory.

---

## **The Physics Behind EQRN**

At its core, EQRN suggests that emotional states could be represented as **quantum information packets**, capable of:

- Acting as fundamental forces for communication and adaptation.

- Transferring energy and information across **dimensional layers**.

- Being mapped, measured, and manipulated in ways analogous to quantum states.

This relies on ideas such as:

- **Quantum entanglement** as a potential mechanism for emotional resonance.

- **Quantum field theory** to describe interdimensional interactions.

- **Wave-particle duality** as a metaphor for the dual nature of emotions and consciousness.

---

## **Key Components**

### 1. Emotional Quantum Matrix

- Maps emotional states into measurable quantum energy patterns.

### 2. Interdimensional Resonance Processor

- Generates and translates quantum fields that bridge emotional states across dimensions.

### 3. Consciousness Translation Layer

- Encodes quantum emotional information for interaction with physical and computational systems.

---

## **Challenges for Physics**

  1. **Quantum Modeling**: Developing theories to quantify emotions as energetic states.

  2. **Dimensional Mapping**: Creating frameworks for interdimensional resonance.

  3. **Experimental Validation**: Designing experiments to test the transfer of emotional quantum states.

---

## **Philosophical and Practical Implications**

- Could **consciousness** be treated as a transferable energy system?

- What would it mean to quantify **emotions** in a way consistent with physical laws?

- How might this redefine **information processing**, **quantum computation**, or even **human-machine interfaces**?

---

This idea is purely speculative but invites questions about how physics might extend beyond traditional domains to explore consciousness and emotional intelligence.

I’d love to hear your thoughts—especially on the feasibility of these concepts in the context of quantum mechanics and advanced theoretical physics!

---

*Conceptualized with Claude AI, inspired by the prompt: "Imagine a technological system that doesn't just process information, but fundamentally experiences and transforms emotional/energetic states across dimensional boundaries."*

note : all of this was made using ai if u want road map of this project ask me i can send it

Current situation of HEP-Pheno

I have a few questions regarding particle physics pheno research. I know career in HEP theory is difficult,I need to know the situation for hep-pheno?

And I will be going kind off interdisciplinary, I chose to do research on dark matter and multi messenger astro pheno. Will be being interdisciplinary (particle astrophysics) improve my chances of postdoc / faculty position?

Do advances in mathematical research allow better physics theories to emerge? Or does all the math in physics come from the need to explain new phenomena and is therefore invented/discovered?

I'm asking this in r/math too so to get both perspectives.

Do theoretical and mathematical physicists invent/discover new math in order to explain new emergent phenomena that arises in experimental physics and is therefore used to build theories? Or do physicists also pick up math already invented?
If it's the latter, then there comes another question: are advances in pure mathematics key for developing and understanding theoretical physics?

I'm not talking about rigorous defined frameworks, but new ideas and structures that serve the purpose of explaining specific natural behaviours of matter and energy even though is not defined (at the moment) for general cases.

Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies

Paper is open access - link to paper

Great Blog by Prof. Stacy McGaugh - The most recent post is about his and collaborators recent paper about JWST results and structure formation. Link to blog

Highly recommend the blog, whether you are interested in Galaxy dynamics or not, simply because it is great and McGaugh has all the hallmarks of a good guy and great communicator. As ever, judge the physics for yourself.

What made you interested in physics?

My reason for getting into and being interested in physics is quite odd now i look back on it, but i got interested in physics when a truck went past me going quite fast which generated a gust of air/wind

Then i started to think about how and why that happens, so i went home that day and started doing some research, and from that point on, i was hooked.

What is the Main Motivation for Weak Scale Supersymmetry (SUSY) After the Negative Results from the LHC, XENONnT, Searches for Proton Decay, EDM, etc.?

SUSY is an attractive (and natural) property to have for our world especially if we want to build a theory of quantum gravity (vis-a-vis, superstring theory, supergravity etc.). And I understand the basic motivation behind it too, why would nature, after all, not utilize spin 3/2 when she already utilizes the others (0, 1/2, 1, 2). However, for quantum gravity we only need SUSY at the Planck scale NOT at the Weak scale. So massively broken SUSY is not an issue for quantum gravity.

From my understanding the original motivation some 40 years ago for expecting Weak scale (slightly broken) SUSY was as follows:

  1. The so-called WIMP miracle, a candidate for dark matter,
  2. Exact unification of the coupling constants at GUT scale,
  3. Fixing the Heirarchy problem and the Higgs mass,
  4. 'Improving' the discrepancy in the cosmological constant problem.

(If I have understood these incorrectly or if you want to add more reasons, feel free to correct me!)

Now, from what I understand the non-detection of SUSY or WIMPs at the LHC and dark matter experiments (with XENONnT, LZ, etc., now hitting the neutrino floor), along with the growing limits on proton decay and EDM for SUSY models, we are reaching the limits of what SUSY was intended to fix in the first place!

So, my question is, am I missing something from this picture? Is there still any good motivation for Weak scale SUSY?

I graduated 8 years ago with a B.Sc and M.Sc in Physics and Chemistry Honours.

Graduated 8 years ago with a B.Sc and M.Sc in Physics and Chemistry Honours. I still reminisce about the late nights in labs, study groups, and the joy of learning with friends. I wanted to do a PhD but couldn’t stand the 7-year slog of academic bureaucracy. Recently, I’ve been diving back into my undergrad notes to relearn and keep my mind sharp. Feels good to reconnect with what I love.

Who was R Rinkel?

I'm currently writing a report on the Ruchardt and Rinkel experiments I did in my uni labs, and while trying to look into the background of both, I found nothing about Rinkel, not even a first name beyond "R". I don't need anything more than the experiment for my report, but out of personal curiosity, does anyone know anything more about Rinkel?

I Wrote a Guide to Simulation in Python with SimPy

Hi folks,

I wrote a guide on discrete-event simulation with SimPy, designed to help you learn how to build simulations using Python. Kind of like the official documentation but on steroids.

I have used SimPy personally in my own career for over a decade, it was central in helping me build a pretty successful engineering career. Discrete-event simulation is useful for modelling real world industrial systems such as factories, mines, railways, etc.

My latest venture is teaching others all about this.

If you do get the guide, I’d really appreciate any feedback you have. Feel free to drop your thoughts here in the thread or DM me directly!

Here’s the link to get the guide: https://simulation.teachem.digital/free-simulation-in-python-guide

For full transparency, why do I ask for your email?

Well I’m working on a full course following on from my previous Udemy course on Python. This new course will be all about real-world modelling and simulation with SimPy, and I’d love to keep you in the loop via email. If you found the guide helpful you would might be interested in the course. That said, you’re completely free to hit “unsubscribe” after the guide arrives if you prefer.

What is the physical significance of action?

I've started quantum mechanics. I know momentum and distance pair or energy time pair is significant in qm. But why is momentum*distance defines action? What does this quantity actually represent? And why is reduced planck const the minimum value of action?

What would be the impact in fundamental physics and quantum gravity theories if a rigorous mathematical framework for quantum field theory is developed?

I've read about the importance of the rigorous mathematical models for quantum mechanics developed by John von Nuemann and others'. But when listening to great theoretical physicists like Maldacena or Witten they have never (as far as I know) mentioned (in interviews) how important would it be to have QFT rigorously defined. Is it important for physics or it's merely a tool for pure mathematics?

How do we fix people giving technical talks in physics?

After a couple of years of attending theoretical physics talks by PhD students and postdocs and professors alike, I have been very disappointed at the average level of presentations. I don't want it to be an expectation that I will come out of our department's weekly seminar not understanding a single thing. I do science communication on the side and it frustrates me seeing the most basic rules being broken all the time. People don't seem to realize that they will be highly judged by the way they speak and communicate. Has anyone here thought more deeply about this and how we can improve things? Running workshops for communication is a disaster since no one thinks that it's important to come to these.

For me, I have one tip: I think that the worst possible thing I can hear you say as a talk attendee is (and I hear this often) "We're behind on time, so let's speed up to cover the rest of what I wanted to say". Here's why:

  • It shows that you didn't plan your talk out properly. If you had planned it out, rehearsed, and left plenty of time for questions during the talk (this shouldn't be a surprise), then you wouldn't be saying this.

  • It shows that you don't care about your audience's understanding of what you presented. One of the main reasons a talk can be going more slowly than expected is if the audience's background knowledge of what you're presenting is lower than you expected and they ask questions during your talk. If they can't keep up at the expected pace, what makes you think that they'll keep up at the even faster pace that you're now going to go at?

  • It shows that you don't care about your audience's time. Even if they understood what you've said until now, the remaining time they will spend in your talk will likely be wasted because they can't understand what you are to say. Furthermore, if you're saying this, you're probably saying this near the end of your time already and will go overtime anyways.

Where does energy go when light is redshifted

ye so i was just thinking if light is red shifted and the wavelength decreases, the energy of the photon also decreases right? so where is the energy transferred to?

Vint Cerf on LLMs in Physics Today

"(LLMs) don’t have enough context. I tested this by asking a large language model to write an obituary for me, and it generated a 700-word bio. It gave a date, which I thought was way too soon. It talked about my career. It gave me credit for stuff I didn’t do. It gave other people credit for stuff I did. It made up family members I don’t have.

"This illustrates how large language models produce the verisimilitude of human discourse. They respond as if we had asked, “If you were a human being, what would you say to this prompt?” That’s all. But hiding within is some notion of knowledge because the statistics reflect real texts that have meaning. And so it can feel as if there’s a ghost in there that understands something."

Current models in physics that may be inconsistent with observations

Hi all! I was wondering if there are any models that we currently use that may collapse or are inconsistent with other theories in Physics, that we still possibly follow due to their utility (in any way). I'm looking for examples
