  • Consider this fact, some light waves like radio are large enough that a lot of matter is essentially invisible to their propagation; the radio waves just pass right by without any interactions. This becomes a similar problem when we try and measure such small quantum phenomena like zero-point energy. The quantum energy could be so small that they’re invisible to our detectors, but are in fact still there - the two scales simple cannot interact in a measurable way. So, there’d like still be some quantum energy, just less and less until our detectors could not interact with the incredibly small quanta for measurement.




  • No society should have any businesses or individuals that are ultra rich. It’s one thing to surround yourself with materialistic goods and services, but to use that wealth as power and control over a huge majority is evil. I suspect when the ultra rich have proper self-repairing droves of service robots, worker drones and obedient AI, they won’t have use for most of us - I am not being hyperbole in writing this…






  • As I’m also a non-professional, I’d like to use your your comment to add my experience with studying quantum mechanics:

    From all my studies of both math and lab experiments, intuitively and likely in reality, matter at the quantum level is made of vibrations, oscillations and standing waves of “SpaceTime.” The amplitude, frequency, position, magnetic moment (spin/charge), temperature, pressure and other properties are what we measure and thus describe particles and emergent phenomena like phonons and other quasi-particles.

    So this all seems simple enough, we have mathematical descriptions and tools to measure with, what’s this whole issue with “observation” and how how far do we need to take it?

    My simple answer is: whenever you see “observer”, translate it to interaction. This can be anything, so long as it interacts with the quantum system being “observed.” But what does this really mean, why does it matter so much? Go back to our wave properties and understand that anything quantum that interacts with anything else quantum is actually introducing their own wave properties and thus, allowing quantum interactions. That is, it’s likely impossible to use something with quantum wave properties (which everything has) to precisely measure something else with quantum wave properties and not have some level of wave disruptions - in other words, we cannot have precise measurements because the closer your quantum measuring tool tries to measure another object’s quantum property, the more the interactions influence the results. The Copenhagen perspective, as I’ve come to orient my understanding, is a question of: does the math reflecting these wave interactions/measurements of them, only mathematically describe it, or do we take the math literally and call it reality?

    There are those in both camps and especially as a non-professional, I join the camp that says it only mathematically describes reality. Keep in mind, relativity of all objects makes it so even the very conditions of the experiment can skew results; the quantum level is extremely sensitive to its wave environment and even in a vacuum, the zero-point energy field exists. Also, keep in mind that just because you can’t precisely measure a given property doesn’t mean that you can’t have very good measurements of most/all properties; it’s only a matter of how badly you need to precisely know any given property.

    There’s obviously more nuance, but I think the key thing that I want to impart is not to take quantum mathematics to literally, but it’s the best description and predicting tool that we have for that level of physics.

    You have to go further than that. A huge population only cares about itself and has made it a part of their identity. Those who have it well don’t have to think about those without: drive to or work from home, live and socialize on internet platforms that isolate themselves from the plight of those with less. They can order everything online and have it delivered to their door - they have no clue and depending on how separated they are from those struggling, they may just say, “those people just aren’t working hard enough,” or some similar line of thinking. It’s not hopeless, but we need far more progress in the US, especially with wage inequality and affordable living/homes. Jeff Bazos is allowed to help buy up single family homes so the rich can rent them out…it makes me so angry and sad.


  • I am firmly one of those who doesn’t have high hopes for Dark Matter - or isotropic Dark Energy. For now I think MOND is developing a better representation of gravity and aspects of our cosmology. What I’m most curious about is what, if any, emergent/quasi-fields might form in space where it’s dominated by EM fields; I added gravity as it can still be a factor, given it is a omnipresent field throughout our universe - even in cosmic voids.


  • “Solids are made of only three kinds of particles: electrons, protons, and neutrons. None of these are quasiparticles; instead a quasiparticle is an emergent phenomenon that occurs inside the solid. Therefore, while it is quite possible to have a single particle (electron, proton, or neutron) floating in space, a quasiparticle can only exist inside interacting many-particle systems such as solids.” Quasiparticle Wiki

    I’ve also been studying Phonons on Wiki: " However, photons are fundamental particles that can be individually detected, whereas phonons, being quasiparticles, are an emergent phenomenon."

    This is the micro/quantum phenomena I’m trying to further understand and was wondering if any quasi-fields/particles have been discovered or predicted in space - I couldn’t find any so far.
