    The increasing rarity of new discoveries is just how discoveries work in every field. Early paleontologists found bones literally sticking out of the ground and every single one was a monumental find that described something new and huge. Once the surface is picked over you have to start digging and finds become statistically more likely to be something you already know.
    This is the same for ore mines and oil fields. Eventually you cross the threshold where the goodies are hidden in places that were not economically viable to look before and you need better technology and more time and effort to extract the stuff.
    Sanding a piece of wood, weeding a garden, restoring an old watch, these are all the same principle of diminishing returns. You discover all the big stuff first because it's the most obvious and because it requires the least amount of effort per unit of result.
    I appreciated that perspective. Thanks Sabine

      A friend and I saw an aircraft/UFO that I later found out looks similar to something called the Tr3-B. Look it up.
      It was Groton Connecticut 2006ish. It hovered silently for 5 minutes in the night sky where I could see the silhouette, and lights. 3 lights each corner with one weird one in the middle.
      After 5 minutes of us being like what is that. It took off like a bullet suddenly. Not a rocket or aircraft. I saw no plume or heard anything.
      It headed north before heading over the tree line, and then suddenly popped out heading east. That turn must have been HARD. It was only out of sight for a moment!
      Then it went over the horizon. The entire process took under 10 seconds from hovering to over the horizon.
      We could never figure out if was small, and silent. Or large, and high up. Yet just last year Sandboxx news Alex Hollins told his story of seeing one too which is just insane. He is a respected journalist. He said it was massive!
      I cannot explain that, and I won't. My friend says aliens, or dimensional beings. I don't know about that.
      I think Alex, my friend, and I saw the same thing. Yet I can't be certain if Alex saw a different craft.

      But we know that we still don't know a lot of things. And maybe we can never know everything.
      Also, our resources are growing exponentially, and our tools are getting better too. So It would make sense to still discover things at the same pace. We do find bones regularly btw., and even entire cities. And there are still plenty of places we haven't even looked yet, like Antarctica.

    • @formes2388
      @formes2388 9 วันที่ผ่านมา

      Yes, but no. There is a world of information just below the surface that has not yet been discovered in terms of Dinosaurs, Rome, Germania, The Celts, the Chinese, the... everything. There is SO MUCH their. Discovering it requires two things: Passion, and incentive. Beyond this though - if we consider the average total man hours per discovery and track that over time, it's stayed relatively consistent for millennia really. The amount of people relative to the total populace doing research is small - and while research and discovery is more difficult then say 500 years ago, we have far better tools for doing that discovery.
      So the question: What is going on? To understand: We have to understand what drove funding and research in the past - vs. what drives it today.
      In the past: Military interest, and wealthy people interested in a topic. Today: It's mostly driven through political interest, and while there is still military interest - that military interest has been diminished mostly to the realm of the militaries own capability.
      Historically, Military interest would include, but not necessarily limited to: Ancient cultural finds, Geological surveys, understanding local flora/fauna, potential resource deposits, and more. Why this fell away is largely in the post WWII era - we shifted from a dominate, colonize, exploit operation and we shifted to a Trade based relations operational process. After all: If you aren't planning to occupy a region - you don't need justification such as "Our ancestors lived their".
      Today: Military interest - was basically replaced by Political interest, and from this we have seen a complete disregard to studies that even suggest something other then human sources are driving climate change. We see string theory dominate the field through funding grabs as compared to every other form of theoretical physics stifling potential discovery. And the list keeps on going.
      When you politicize something, and create a bureaucratic process - when every research paper needs to deal in some way with climate to get funding - good research is stifled, in favour of people more able and tuned into the political BS. And as a result: Less good science gets done.

      PTT a real technique in cancer treatment, and it twigged me to think DEW and weather manipulation. It can be done no doubt. The principle of Photothermal Therapy (PTT)-localized heating through light absorption by nanoparticles-could theoretically be applied to atmospheric or environmental manipulation.
      How PTT Works
      Photosensitizer Agent:
      PTT relies on materials like nanoparticles (e.g., gold nanoparticles, graphene, or carbon nanotubes) that absorb NIR light and convert it into heat. These materials are often functionalized to specifically target cancer cells.
      NIR Light Activation:
      A NIR laser is used to penetrate tissue, as it can reach deeper tissues due to minimal absorption by biological components.
      Heat Generation:
      The nanoparticles absorb the NIR light and convert it into heat. This localized hyperthermia induces cancer cell death, typically through protein denaturation and membrane disruption.
      Cancer Cell Death:
      The heat damages cancer cells without significantly affecting surrounding healthy tissue, as the treatment is precisely targeted.
      Here's an exploration of the idea: Applying PTT Principles to Atmosphere Seeding.
      Seeding the Atmosphere with Nanoparticles: Material Selection: Similar to gold nanoparticles in PTT, materials with high absorption efficiency at specific wavelengths (e.g., carbon black, graphene, or engineered metal oxides) could be dispersed in the atmosphere. Size and Composition: Nanoparticles would need to be engineered to resonate with specific wavelengths of light, such as infrared or visible sunlight.
      Heating the Atmosphere or Target Areas: Localized Heating: If nanoparticles are tailored to absorb specific frequencies of light (e.g., solar radiation or directed laser beams), they would convert that energy into heat, warming the surrounding air or objects immersed in the seeded area. Selective Heating: By controlling the dispersion of nanoparticles, specific regions or layers of the atmosphere could be targeted. For instance: Warming cold air masses to influence weather patterns. Melting snow or ice in targeted regions. Preventing frost formation in agricultural fields.
      Directed Energy Application: Infrared lasers or high-intensity light sources could be used to selectively activate nanoparticles within the seeded region, focusing energy and maximizing efficiency.
      Potential Applications Weather Modification: Influence local weather patterns by heating air masses or redirecting wind flows. Mitigate frost damage to crops by warming specific areas of farmland.
      Solar Energy Enhancement: Increase localized heat absorption in regions where solar energy is insufficient (e.g., in cold climates or during the winter).
      Thermal Decontamination: Selectively heat areas to kill pathogens or pests in agricultural or urban settings.

    I think this is a great overview and the points about compatibility with what we know are spot on. However I think there is a 4th way that you glossed over, which are some kind of emergent behaviour that only shows up in specific circumstances. For instance, Cooper pairs in superconductivity, or magic angles in graphene. So you are correct that these aren't new fundamental forces, fields or particles, but specific arrangements of fundamentals may reveal new and surprising properties that aren't apparent in other contexts.

    Excellent video, Sabine! I especially liked the part where you note that the place to look for scientific upsets is in emergent properties, rather than in fundamental ones. It's especially striking when you consider that life and consciousness are emergent properties of the physics of our universe. But, coming to the fundamental rules of our universe completely cold, no one would predict it giving rise to something as complex and varied as biology.
    That all said, the level of cringe I felt at watching some of the pseudoscience clips was legitimately painful for me. Like, if somebody has to dodge the most basic of questions about the "world shattering" assertions they're making, then you know they're absolutely full of crap.

      no. the entire world is controlled by a single shadow government. the rivalry between nations is artificial. its just a giant conspiracy against humanity, freedom and civilization. the tech is hidden not because its dangerous, its hidden because renders most of the oppressive economy obsolete. anti gravity devices generate energy when flying, because they get pushed by earth gravity. they are "free energy" devices in the sense that they gain more energy than they loose, because they are pushed by earths gravity instead of fighting it. effectively, its a method of transportation at hypersonic speed in the atmosphere and close to light speed in space, with instant acceleration produced by tiny forces cause there is no weight to overcome. it has effectively zero energy cost when in flight and close to a strong mass like a planet, its relatively safe because you cannot ever hit the ground at high speed so crashing it is difficult and if done, relatively harmless as the force is tiny. it eliminates the need for all transportation infrastructure. no streets, no ships, no planes, no large runways, faster, safer, no energy cost, no fuel. and it also overcomes all issue of space travel. think about how much cheaper this would make everything.
      remove all the successive transportation and energy cost that in prices. as you dont need street infrastructure, real estate will be much cheaper, can be build everywhere, and energy can be generated everywhere, without any need for fuel, mining, imports and no danger or pollution.
      if this was made public, humans would instantly be free from the oppressive control of governments and ruling elites, and thats precisely why this is hidden. the anti gravitic nature is not the troubling part, its the fact that allows for very convenient energy generation and simultaneously reduces energy consumption down to near zero, since transportation would not required any.

    Here's my issue with your argument, Sabine. 'Maths' are so unbelievably challenging, complex, and diverse, that the talent pool of humans who can understand the full breadth and depth of physics topics has got to be near zero. Is it possible there are blind spots? Yes. Add to this the innumerable edge cases, cusps, and asymptotes that can be exploited across all relevant equations, and I'm not convinced that it's simply "impossible" to do anything novel from this point on with the topics of gravity and time. The other factor that really challenges anyone in this space is access to advanced materials, vacuum physics, and photonics experiments. This is why we end up with teams of researchers and peer reviewed papers, yet this very workflow seems to create a glacial pace of innovation and discovery, rife with the pressure of 'next funding round' and only incremental progress. I see a parallel in new product prototyping, the space I play in. Regardless of budget, R&D projects / prototypes seem to apply the 80/20 rule out of necessity. If we had the time and money to only explore the far-fetched 20% of creative solutions and apply them to new products, we'd have some really cool stuff. Same can probably be said of math and physics. So, stay rooted in reality, yes, but don't close off the possibility of new phenomena. At one time someone was probably sh*tting on the idea of a laser, a semiconductor, or radio waves. For one thing, we have not fully explored superconductors, and if there can be zero resistance in electron flow, then a lot of 'maths' probably go to infinity. Same with BECs and even novel Piezo materials. That's my EE take on the whole thing.

    You do not need advanced tech and structures to see the effects of a gravitic propulsion system. You just need to look into nature and study the flight characteristics of bumblebees able to lift their giant body with tiny wings and able to fly in perfectly straight lines completely unimpacted by even strong crosswinds. Explain that with classical aerodynamics. Not easy? Try magnetohydrodynamics. It will work. This is the key to gravitic propulsion.

    It is a very precise and excellent explanation.
    The uncertainty in metric measurement is truly very complex. If the metric has uncertainties in the measured distance traveled by a photon and its arrival time, many issues arise.
    The first issue is in measurement. The Hamiltonian encounters a non-Hermitian problem, as defined by Pauli. If the Hamiltonian H is semi-positive definite (H≥0), then if a time operator That exists, its eigenvalues t should cover all possible times, meaning from negative infinity to infinity. This is because physical phenomena can occur at any time, not just at t≥0. However, this contradicts the Hamiltonian H .
    If the time operator That exists, it would form a conjugate relationship with H :
    [H,That]=ihbar
    This is similar to the commutation relation between position and momentum. However, if H has only non-negative eigenvalues (E≥0), such a commutation relation is impossible. This issue was explicitly pointed out by Pauli's theorem.
    It is not entirely impossible, though. Before I conceived the uncertainty relation of the metric, I encountered this problem. At that time, I was considering defining the metric through gauge fields of translation, and when I thought about expressing translations in the form of spinors, something strange happened. If a reflection to the past occurred, it would cause unitarity and causality problems. However, this did not prevent reflections to past time points because multiple reflections to past time points could still occur. But the direction of time flow still pointed to the future, thus avoiding causality issues, as the past still influences the future. The unitarity problem was also resolved because the total energy represented by the Hamiltonian would not flow to the past-it still pointed to the future.
    However, when I realized that the metric is actually measured through photons' traveled distance and arrival time, I abandoned that approach and turned to the issue of metric uncertainty.
    Now is the time to bring it back into use. The Hamiltonian can be resolved by allowing travel to the past while keeping time directed toward the future. This is similar to the cyclical nature of cosmic time: if we return to the past but time still moves forward, we eventually return to the original time point, just like a closed cycle.
    This requires a very large metric uncertainty to achieve because it needs to cover the phase of different time states. Essentially, this can only happen inside a black hole.
    However, problems remain numerous. The issue of Hilbert space completeness still exists because, when the metric is uncertain,
    g_munu(x) -> g_munu(x) + delta g_munu(x)
    the inner product becomes
    =∫d^n x sqar(|g(x)+ delta g(x)|) psi*(x)phi(x)
    Expanding it:
    sqar(|g(x)+ delta g(x)|)≈sqar |g(x)| (1+1/2Tr[deltag(x)])
    The corrected inner product then becomes:
    =[∫d^n x sqar(|g(x)|) psi*(x)phi(x)] + [1/2∫ d^n x sqar(|g(x)|)Tr[delta g(x)] psi*(x)phi(x)]
    If delta g(x) is a small perturbation, the change in the inner product is a secondary correction and can be ignored.
    However, if delta g(x) fluctuates significantly, the inner product may undergo a noticeable change, potentially breaking the orthogonality between basis states.
    If delta g(x) is large or randomly distributed, additional nonzero inner products may emerge between different states, making them no longer strictly orthogonal.
    A clearer way to understand this is to consider the collapse of Hilbert space. For example, the orbital and energy levels of different electrons could become identical. In the process of neutron stars collapsing into black holes, all energy levels tend to converge.
    When the metric's uncertainty becomes large enough, the differences between neutron energy levels may shrink or even completely disappear.
    This could even lead to the collapse of the metric itself, making all metric states identical. Although we could argue that this phenomenon necessarily occurs when a neutron collapses into a black hole due to the inevitable breakdown of degeneracy, this does not mean we have no way to address it.
    We can incorporate the correction terms into the Hilbert space beforehand, but this requires precise computation of the compensation term. The metric uncertainty is significantly manifested inside black holes, so we must handle quantum perturbative gravity's vacuum corrections. Without addressing this, we cannot determine the compensation term or fully understand the black hole's interior.
    Although we can use metric uncertainty to derive an exponential decay factor in functional integrals, the number of problems remains overwhelming.
    I found that this is not so simple because the coupling constant does not have any uncertainty. Moreover, when we calculate the functional integral, since we are using the Heisenberg picture in quantum field theory, our phase factor is a positive oscillatory factor. The usual approach is to transform Minkowski spacetime into Euclidean space, which results in an exponentially decaying factor similar to statistical mechanics. However, when quantum perturbative gravity is transformed into Euclidean space, it has a negative kinetic term, which is known as the conformal factor problem. This directly leads to a divergent Gaussian integral instead of a convergent one.
    Actually, this issue is not that difficult to resolve. In the Schrödinger equation, the oscillatory factor is indeed negative because the Schrödinger picture follows the Hamiltonian formulation. Therefore, the Heisenberg picture, when converted into the Lagrangian action formulation, results in a positive oscillatory factor. As long as we use the Schrödinger picture in quantum field theory, the oscillatory phase factor naturally takes the form of an exponential decay. Since we do not perform analytic continuation to the complex plane, transforming into Euclidean space ensures that the decay factor remains exponential.
    However, there is still uncertainty regarding whether the metric measurement affects propagators and vertex terms. If it only influences the measure, it would merely change the interference weight factor without affecting loop calculations. But this is clearly impossible because the uncertainty in position and momentum affects the propagation of the field, and curvature is based on the metric. Therefore, both curvature interactions and propagation will be influenced by the metric uncertainty, leading to exponential decay factors in both propagators and vertex terms. Consequently, we can say that the divergence in quantum perturbative gravity is significantly suppressed, but it is still necessary to verify whether this is indeed the case.

      ​@@SabineHossenfelderAll of this is just a coincidence. A wrong starting point gave me the technique. I posted it under your *What Everyone Gets Wrong about AI* video out of curiosity at the time. I'll post it again, but this kind of idea itself comes with many challenges and an uncertain process that may not necessarily be correct.
      I have an idea: although quantum perturbative gravity is non-renormalizable, we have not fully accounted for the fact that the metric itself may be quantized. In classical general relativity, one measures the metric by sending photons from A to B, measuring the travel time t, and then using d = c t to determine the distance. However, we have not considered quantum effects in this process. When we use photons to measure distance, the more precisely we measure the photon's arrival time, the less precisely we know the distance it traveled; conversely, the more precisely we measure the distance, the less precisely we know its arrival time. This leads to an uncertainty relation delta d * delta t≥ l^2_p. At first glance, this may seem unrelated to the renormalization of quantum gravity perturbations.
      But let us consider the path integral
      Z =intergal D g_munu e^(iS[g_munu] / hbar)
      Since the metric g_munu is quantized, we should integrate over ghat_munu. This introduces an extra factor
      e^(-delta(g)^2/l^2_p)
      which comes from using delta d * delta t ≥ l^2_p, reflecting the photon's time-distance measurement uncertainty. Thus, we have
      Z =intergal D g_munu e^(iS[g_munu] / hbar) e^(-delta(g)^2/l^2_p)
      Therefore, when delta g is large, contributions from high-energy states are suppressed. At every loop order, this can tame divergences. The reason is that when the momentum of the metric becomes too high, it becomes impossible to measure time and distance in a well-defined way, causing the metric to “foam up.” We often hear about spacetime “foam,” but seldom about what happens afterward. Once the metric enters this foamy regime, it can no longer sustain a well-defined geometry, so its curvature cannot continue increasing. Consequently, there is no singularity. This means that extremely small distances and the extreme curvatures at black hole singularities both vanish due to this effect.
