About This Sound Room

ξ = Ø and other fun stuff

  1. What's new in this room
  2. https://www.sciencenews.org/article/black-hole-first-picture-event-horizon-telescope
  3. another mind blower, even if you'd heard of its other name before. The of and to. A in is I. That it, for you, was with on. As have ... but be they.
  4. If you hang through the refreshers, I bet he'll blow your mind at the end.....
  5. Yes, if there's no causal connection between two objects, then they get diplomatic immunity. WHen people talk of the speed of light as being a limit, there should be an asterisk down to the margin
  6. Optimized for my backyard at 10PM, but applicable to night time in the midwest
  7. How the blackness of space used to be orange. For some reason, his explanation of what it meant for the universe to have become 'transparent' clicked (with me) some 35 years later.....
  8. Yes, I'm not sure why he didn't explore that; perhaps he didn't want to obfuscate the main topic
  9. He gets some of it right. I was in Honors physics class in my first year, and one assignment was to mathematically describe the tides. I got the right answers at selected points, but not the overall function. Function was 3rd order and had an R^3 in it. The way to find the solution is as he says, to treat earth as totally covered in water. Then you assume if there is a change in gravitational potential, water will flow. So the whole earth has an equipotential surface. Calculate that, and you have the tides. I think it was about a meter. The reason why Bay of Fundy in Nova Scotia has such high tides is because there's a body of water that has a resonant frequency equal to the tidal period. Water sloshes in and out with a period of 12 hours.
  10. Your first post re universal shape said This conflates two contradicting ideas, and began my attempt to get your contributions to this topic back on track. Remember that, in ALL of this, I see my self more as a line judge, trying to keep a topic on course, rather than an all knowing being. As such, I was trying to illustrate where your comprehension of flatness, expansion and the idea of a non-Euclidian space deviates from what those that study these effects are actually saying. Your statement above is more in line with the 'steady state' theorists than what has followed since, and I was attempting to re-direct away from those outdated ideas. I am not in any way referring to Euclidian geometry, scales or distances; yes, you are using an age and conflating it with an idea of curvature, arriving at an erroneous conclusion (when you started talking about horizons). The flatness of a Non-Euclidian space has nothing to do with its size. It's possible for a theory of universal geometry to be so completely curved that it is not much larger than the earth; IN such a universe, a 'flat' earth would appear spherical, so NO, curved space does not imply huganomious-ness. I wasn't indicting your logic, rather I was trying to correct your interpretation of other's frameworks Researches talk about 'Super Massive' black holes all the time. They know what they mean (that the observable size of a black hole has no real definition, as it exists as a point like rupture in the fabric of space-time). Thus, there is no scalar comparison between a non-defined point in space-time and the observable universe. You were talking about horizons and topology when you brought the idea that a hill's existence doesn't negated the idea of a much more curved horizon, and that comparing scales of curvature was somehow applicable. I mentioned how this is incorrect, and you brought it up again in your riposte. Well, I wasn't talking about either of those concepts, but I agree; I've thrown out ideas for this science 'club' for about a month, and there's no traction here. Did you get any meaningful data regarding sound rooms? I hope it was worthwhile in that sense at least. an observation: I mentioned to you when we were setting up this club that crippling the 'recently posted' code by eliminating sound room additions kinda sucked. I still feel this way. Yes, there are other ways to promote a sound room (e.g. via a 'digest' post as I've done every Sunday), but you don't get a feeling at ALL for engagement. The room itself has overall view and reply stats, but they are comprehensive, including ALL dates of a topic. For instance, a topic may have very intense interest at first, but then nothing. Another topic may have the same overall number of engagements, but over the course of several weeks. There's currently no way to determine engagement frequency, other than writing down how many reads for each topic for each day and then subtracting from yesterday's data. The 'recently posted' list would allow this if it wasn't crippled. Remember that, in ALL of this, I see my self more as a line judge, trying to keep a topic on course, rather than an all knowing being.
  11. @RichP714 I personally never claimed the universe was flat, nor did I claim it was curved - I merely communicated what the prevailing theory is and how physicists themselves explain it. I used the age scale, you are using the euclidean distance scale. Again it's not my logic here...the point is if it is curved it is huganomious! For practical purposes, it is believed to be flat. If it is not flat, then it is much, much bigger than we expect. By scalar comparison, a black hole is infinitesimal compared to space-time. There's no meaningful ratio between the two, in fact. That is not to say the phenomenon of space-time can't be explored more dramatically by observing and thinking about black holes, only that by order of actual scale, their disturbances are not expected to influence the curvature of space-time, no more than Mount Everest defines the shape of the Earth, even though one could fall to their death from its summit. About the video... Yeah, I read Machio Kaku's 4th Dimension too, and Flatland. It's rather pointless to get that deep here...
  12. B-man mentioned that when he was in school, the atom was the smallest object in nature; electrons have been known since 1890; I had no idea he was so long lived; congrats!
  13. A friend of mine worked on the (short lived) Superconducting Supercollider; it cost more to shut down than it would have to complete.
  14. Yep......although I remember a former me used to say "I'll sleep when I'm dead'
  15. Another way to look at it, some decades later, that may blow your mind, again
