About This Sound Room

ξ = Ø and other fun stuff
  1. What's new in this room
  2. Just when we got used to the fact that Polar bear fur is NOT white (it's clear), now this: https://www.aao.org/eye-health/tips-prevention/your-blue-eyes-arent-really-blue
  3. How can they see what they're doing? Too fast for me
  4. I'm so old that when I see "quad" I think of this:
  5. Oh wow! My grandson has a cheapo quad; it's nothing like that!

  8. Yes, this is a great clarification, thanks! There was a mention of interactions at the Planck length but I failed to connect that to affecting just electrons, gluons, and quarks directly.
  9. AFAIK, large particle interaction with the Higgs Field is not a thing. The Higgs field imparts mass to sub-atomic particles by tugging at them at Planck length scales, so electrons, gluons, quarks will interact with Higgs. Atoms/molecules/organisms are too large to directly interact with the Higgs field; the mass of those larger constructs is imparted by the force of the gluons holding them together. There's a difference between being timeless, being time agnostic and causality (c). I think you mentioned Feynman diagrams in another post; those graphically show that interactions between sub-atomic particles are effectively equivalent interactions between their anti-matter pair, but reversing the direction of time (they are time agnostic, but still obey causality). In this way, any interaction between any 'things' (sub-atomic or macro scale) involves time in one way or another; back-to-front or reverse. This PBS speaker (he is a physicist) has many videos on youtube; I think he's still the current host of the show; the show itself is pretty good IMO, they show concepts graphically for the most part, but get into the details and the math on occasion, and seeing things like the Lorentz transform presented graphically is pretty neat. His post on why time has a direction is pretty neat, among others. I don't know if this gives any rationale that you were looking for, I might have got it wrong or not understood the question, but I think a more correct statement would have been that as long as a sub-atomic particle is interacting with others, it has to experience time in one way or another, but not necessarily in the same way that the aggregate of those sub-atomic particles (the 'thing') does.
  10. The newly discovered 'geometric approach' to particle interactions by researchers involves a higher-dimensional object called the amplituhedron. The object suggests that particles interactions are simply the result geometry (and nothing else!) and even though the amplituhedron IS NOT built out of normal space-time and probabilities it appears to miraculously predict all possible particle decays in nature. It also removes locality as a requirement (the notion that particles can interact only from adjoining positions in space and time). A fascinating tool.
  11. In "The Origin of Matter and Time" video the speaker says "time and mass and matter become emergent (not fundamental) properties of the causal propagation of patterns of interactions between timeless, massless parts". This is a pretty amazing statement. I believe the 'parts' he refers to are the sub-atomic particles which he postulates are not time-interactive unlike larger aggregate particles which directly interact with time. Is the large particle interaction with the Higgs Field (and other fields/particles) the reason for this supposition differentiating small vs. large-aggregate particle relationship with 'time'? Does anyone know to what extent this has been experimentally proven or is it still just theory? Any known reference in a scientific journal?
  12. Scientists Discover a Jewel at the Heart of Quantum Physics PHYSICISTS REPORTED THIS week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. https://www.wired.com/2013/12/amplituhedron-jewel-quantum-physics/
  13. Flyby of Jupiter aboard Juno, did you see the dolphin?
  14. WE all get depressed at times. The next time you are thinking its all a bit too overwhelming, or that the universe is against you, just remember: He probably wasn't thinking this way at the time, but since YOU are mass, the universe is always giving you a hug!
