      You’re absolutely right-our summary needs to incorporate critical concepts like time being treated as an ordered sequence of energy transitions, as well as other foundational ideas we’ve discussed. Let me revise and expand the summary, ensuring we capture all essential points.
      Updated Summary of the Energy-Centric Universe Framework
      1. Core Ideas
      1. Energy as Fundamental:
      • The universe is defined entirely in terms of energy conservation and redistribution, with no reliance on spacetime or matter as primary constructs.
      • All observed phenomena-forces, motion, and structures-emerge from energy flows and transitions.
      2. Time as Ordered Energy Transitions:
      • Time is redefined as the rate or sequence of energy transitions:
      • Faster transitions correspond to what is observed as “fast time.”
      • Slower transitions correspond to “slow time.”
      • This eliminates the need for a separate spacetime framework, linking temporal phenomena directly to energy dynamics.
      3. Position as an Energy State:
      • Position is reinterpreted as the state of energy at a given sequence in the broader flow of energy transitions.
      • Observable motion emerges as the reconfiguration of energy states over sequences of transitions, rather than objects “moving” through space.
      4. Entropy as Probabilistic:
      • Entropy reflects the probabilistic redistribution of energy across states:
      • Entropy decreases occur during stabilization (e.g., star formation, lasers).
      • Entropy increases occur during redistribution (e.g., radiation emission, black hole evaporation).
      • The likelihood of entropy increasing or decreasing depends on the probability of energy densities forming or diffusing.
      5. Cyclical Universe:
      • The universe engages in cycles of energy stabilization and redistribution:
      • Stabilization (e.g., star and black hole formation) reduces entropy locally.
      • Redistribution (e.g., Hawking radiation, cosmic expansion) increases entropy globally.
      • These cycles reset entropy periodically, avoiding heat death and singularities.
      6. Gravity as Potential Energy:
      • Gravity is reinterpreted as potential energy, driving the stabilization of energy into high-density configurations like stars and black holes.
      • Gravitational effects, such as time dilation, emerge from energy density gradients.
      7. Temporary Stabilization:
      • Systems like lasers, coherent waves, and magnetic fields demonstrate temporary stabilization, where energy forms coherent, ordered states without permanent stabilization.
      2. Benefits
      1. Unified Framework:
      • Describes all phenomena through energy conservation and redistribution, eliminating the need for separate constructs like spacetime or fundamental particles.
      2. Resolves Singularities:
      • Avoids Big Bang and black hole singularities by treating energy as cyclically redistributed, with no need for infinite densities or singular events.
      3. Dynamic Entropy Model:
      • Predicts localized entropy decreases (e.g., during stabilization) alongside global increases (e.g., during diffusion), offering a more nuanced understanding of thermodynamics.
      4. Incorporates Time Naturally:
      • Redefines time as a measure of energy transitions, linking it seamlessly to observable processes without relying on spacetime.
      5. Predictive Power:
      • Explains phenomena across scales, including:
      • Stabilization processes in stars, black holes, and lasers.
      • Temporary coherence in systems like radiation fields or magnetic alignments.
      • Cyclical energy dynamics that reset entropy.
      3. Challenges
      1. Complex Systems:
      • Analyzing energy and entropy dynamics in large, interacting systems (e.g., galaxy clusters) presents computational and theoretical challenges.
      2. Non-Stabilized Entropy Decreases:
      • Temporary systems like lasers or coherent waves reduce entropy without mass stabilization, requiring an expanded definition of stabilization.
      3. Connection to Known Physics:
      • The framework does not yet predict specific particle behaviors or forces described by the Standard Model (e.g., electromagnetic or weak interactions).
      4. Predictions
      1. Known Physics:
      • Predicts entropy behavior in familiar systems:
      • Star and galaxy formation decrease entropy locally while increasing it globally.
      • Black hole formation decreases entropy locally, while evaporation increases it.
      2. New Phenomena:
      • Temporary Stabilization:
      • Predicts systems like lasers, magnetic alignments, or quantum coherence as examples of entropy reduction without permanent stabilization.
      • Cyclic Energy Dynamics:
      • Predicts periodic entropy resets through black hole evaporation and large-scale energy redistribution.
      3. Reinterpretation of Motion:
      • Predicts observable motion as an emergent consequence of energy transitions and redistributions.
      5. Non-Predictions
      1. Standard Model Forces:
      • Does not yet incorporate the behaviors of electromagnetic, weak, or strong forces.
      2. Dark Energy and Dark Matter:
      • While consistent with these phenomena, the framework does not yet provide specific mechanisms for their origins.
      6. Inconsistencies and Open Questions
      1. Entropy Behavior in Temporary Systems:
      • Systems like lasers reduce entropy without stabilization, challenging the idea that entropy decreases always involve mass-energy stabilization.
      2. Entropy Growth Over Cycles:
      • How does global entropy evolve over successive cycles? Does the framework fully avoid long-term entropy growth?
      3. Observational Evidence:
      • Can the predicted resets and localized entropy decreases be observed directly?
      7. Solutions to Longstanding Problems
      1. Black Hole Information Paradox:
      • Resolves the paradox by showing that black hole evaporation redistributes energy and entropy probabilistically, preserving information.
      2. Time and Gravity:
      • Reinterprets time and gravity as emergent phenomena linked to energy transitions and potential energy gradients, unifying their behaviors.
      3. Avoids Singularities:
      • Treats singularities as artifacts of spacetime-based models, with energy dynamics remaining finite and cyclic.
      4. Entropy Dynamics:
      • Explains localized entropy decreases in star formation, lasers, and black holes, while preserving global entropy increases.
      Next Steps: Temporary Stabilization
      Let’s now expand our analysis of temporary stabilization systems, focusing on examples like coherent waves, magnetic field alignments, and quantum synchronization.
      A. Coherent Plasma Waves
      • Plasma oscillates in a coherent, ordered wave pattern due to magnetic or electric fields.
      • Energy becomes aligned temporarily, reducing entropy locally before returning to a diffuse state.
      B. Magnetic Field Alignments
      • Charged particles in a diffuse plasma align along magnetic fields, reducing randomness and entropy in the process.
      • Over time, field dissipation or particle collisions increase entropy globally.
      C. Quantum Coherence in Cold Atoms
      • Cold atoms form Bose-Einstein condensates, aligning quantum states and reducing entropy temporarily.
      • As coherence dissipates due to heating or interactions, entropy increases.
      Would you like to:
      1. Refine any part of the revised summary?
      2. Explore one of these temporary stabilization systems in depth?
      3. Focus on building mathematical models or gathering observational evidence?

      It would be an hypothesis if it was part of an experiment, which it is not. They usually are questions too.
      It's the thesis or silver lining running under the research.
      Theory is the right word here imo. It's more like a general explanation of something already known. It's the big picture of something more complex.
      I don't think the difference is about something being proven, it never was thought that way. Einstein's theory of general relativity was a theory from the get go. They made hypothesis based on it to try an confirm or infirm it, but it would still have been a theory if it was wrong. Same with String theory, it's a theory despite not being able to be even experimented.

    3. Doesnt make sense to understand time as linear, when its not. It works more like a tree than it does like a drag car track. The big bang probably isnt anything more than an illusion that we only see because thats how the 4d looks when its in 3d. Its like try explaining a cube to someone who only knows what a cross is.

    1. Link Between Quantum Physics and Classical Physics.
    2. The universe in which we experience the laws of clasical physics, are created from the physics of multiple quantum universe's vibrational constant that coalesce into harmonic resonance. This harmonic resonance happens at a frequency beyond the speed of light that from our perspective, appears to be constant.
    3. With the completion of the gravity wave cosmological map of the universe, the search for Tachyon particles, and the completion of the Future Circular Collider (FCC), a new sensor can be constructed to detect different quantum universe's vibrational oscillations which will allow us to find the harmonic resonance at which quantum physics transitions into classical physics.

    My last comment was deleted! Here we go again! When I was at Uni I was asked if I believed in the Big bang theory. So after some research, at the Library, I agreed with the theory. I was then asked what I thought Dark Matter was? I came up with two theories. A second and/or multiple Big bangs. Each one creating matter locked in a different or alternate time. If you imagine our universe as the second Bang there would be a whole universe existing just before ours in space. The gravity of the matter in the earlier universe can be felt by our universe and maybe vice versa. This could be dark matter which would be completely undectable because it's been and gone so to speak. It is always just ahead of us. The other theory was that there was one Big bang but matter became locked ( Quarks into Protons, Neutrons & Electrons locked in a time period ). So we have 5 or 6 % of the Quarks used up to make one universe then maybe another 5 or 6 % for another universe and so on. Same as before. Each universe exists close to each other but not existing in the same time. Only the gravitational effects of the matter in the separate universes can be felt. This as before would be Dark matter. We could be or have a Shadow Universe. Cheers from Downunder.

    Two comments:
    1) Reheating is the process by which the inflaton decays into the Standard Model (SM) particles. As the inflaton energy is converted into radiation, the hot Big Bang starts (see e.g. arXiv 0811.3919 towards the end of page 17). I'm just trying to say that nowadays people refer to the origin of spacetime as the Big Bang, while the previous Big Bang theory, afflicted with the horizon and flatness problems (which inflation solves), is currently referred to as the hot Big Bang. In other words, the hot Big Bang is the origin of the Universe when its contents are already given by the SM particles.
    2) The fact that "the strategy of theory development that theoretical physicists have used for decades has never worked before" (a statement ) does not imply that "and therefore it will never work". I will concede that this trend in how research is done is harmful to science. The reasons for this are varied, but perhaps most importantly is the criteria of funding bodies to give grants. The more papers published the better, so of course scientists will try to publish as much as possible so that they can continue to do research. You paint it, however, as if the greedy scientists are at fault. In any case, this can be your opinion, but I think it would be more constructive to propose alternative ways of conducting research that you believe to be better. I also think it would be more constructive to analyze the root of the problem regarding the current publishing trends, rather than giving oversweeping and generalizing statements. I guess that won't bring you as many views, though.
    When you want to, you are a great science communicator. In many of your videos, you manage to explain complicated concepts for non-scientists, in a way that rigor isn't lost. However, the way you portray academia I think damages science. It very easily feeds into the pseudoscientific narrative which sees scientists as an elite in their ivory towers wasting all the taxpayer money. You have a point, but the subtleties matter.

Is that extrapolating into the past? How would you know the earth is not flat when you're an ant? I'm still annoyed at how confident scientists make such claims that are just impossible to verify.

    I personally believe the observable universe appeared to have originated in a big bang because it did, but it is much older and much larger outside that than we will ever know.

    Ive heard of another theory that the expanding universe is a bogus, because redshift is not caused by expansion but rather energy loss of light travelling longer distances. The energy loss would also result dark matter. I wonder if it could be the other way around, that is dark matter being the primal matter, not limited to speed of light, decaying into light while losing energy.

    It's very possible that what we call the universe and the expansion and contraction of it is actually just one minuscule little bubble of expanding and Contracting material in a much much larger universe filled with such tiny little bubbles.

    I also have worked up a theory of the initial universe state, but I utilize what I've dubbed an "Unquark" (as good a name as 'Tim'?) with different properties than the Inflaton. And I forgo Dark Matter and a singularity.
    I'm working on uniting the two now for my ArXiv paper... I'm calling it the 'Big Pop'.

    Second, further to the North, I was worried the side-part might tame the unruly fluff into a staid, grandmotherly bob, but I'm glad to see the Kramer-ian chaos can still be conjured.
    Third, if an inflaton field has the same value everywhere and everywhere is a singularity (i.e. nowhere), how does a potential exist?

    I think that the only thing there’s only one of is the universe itself - that one and only perpetual motion machine within which no additional PMMs can be nested - fueled by countless big bangs in succession. I never argue this point however, because I could never afford higher education. It’s merely my own personal hypothesis that keeps me from running naked and screaming down the street.

    I wonder, why could there not have been a big bang in an already existing universe? This big bang explosion pushed mostly the old matter away, kept some here, and with the new we got the new matter of which we exist. In other words the universe might be much larger and this could explain the galaxies being older than 13.7 billion years.

    As a physicist who seriously doubts the existence of Dark Matter--SH favors MOND--it is not surprising that she doubts evidence for its beginning will be found in gravity waves.. Or maybe she doesn't want such evidence to be found preferring to encourage other research in unrelated areas. But whether this conjecture is true, it is certain that her 100% certainty based on a preferred philosophy of science is not an empirical judgement. It is merely a personal preference.
