  1. Thanks for the clearly written paper, John. Isn't this the DeSitter solution from 1917? Seems to match this in my book. I shall study further the general equations which are linearized to yield the first order expression of Hubble constant.
  2. I hope those who have hacked my system of expression are now under rubble.
  3. iNow, I do not know who you think you are talking to.
  4. Thanks, I will again try to use SPYBOT, which I did for a while. I was just hijacked four times trying to get here. With any luck these jerks are under Szechuan rubble.
  5. I am badly hacked by Chinese pigs. I am unceasingly intruded upon by "Liu-liu" something, and have a bogus WARNING page, and get 'syscleaner' intrusion. I now cannot download AVAST, and get something with 'selfextract' failure. They are winnning. We are now in the same boat, Transdecimal.
  6. Good discussions, folks. After shopping online for Honda Insights I actually pulled up next to one at the grocery market and had a great talk with its owner. He said he sometimes gets more than 70 mpg. I am looking! I have also walked the walk: I am blessedly child-free, have step-dadded for twelve or so years. I figure we must deal both with our supply and our demand. What is coming of Canada's hemp farming? I grow a few smokable plants, and was impressed when an experienced friend described loosening a circle of two foot radius and mixing in sawdust. My, my, I thought nitrogen and intensive fertilization was needed, but more the humus of friable soil.
  7. .Zephir, your thoughts are wondrous. I am working with 'solidspin' who is formulating quantum representation in a four-D sense outside the light cone, as is demanded by non-locality. I am getting in over my head here, but isn't that what we all came for? Zephir, I lose you at the point of "pot and soap..." for two sentences. I am studying up on cosmologic solutions, and am feeling some heebie-jeebies because I realize I do not yet command the field of possible model forms. However this statement in my textbook makes sense: "We notice at once that the general form of Einstein's equations with [math]\Lambda[/math] not zero does not admit a flat-space solution for an empty universe. This is evident since an empty universe is characterized by [math]{T^a}_b=0[/math] and a flat space is characterized by [math]{R^a}_b=0[/math]; therefore the equations cannot be satisfied unless [math]\Lambda=0[/math]." Yes and the point here is that the RHS source must include an intrinsic pressure in any spatial volume. We find that space is definitely close to being flat. Think about a far-expansion state where mass and light energy densities grow smaller and smaller. Then the last two terms in the field equations must balance. You might say, "Ah but you only put the pressure into the three spatial dimensions!" Good point; we speak of electromagnetic fluctuation energy, what I call fractional photons. Any such energy is characterized both by pressure and by energy density per se, and the latter is expressed in the <0,0> term according to the E&M understanding: [math]P=\frac{c^2} 3 \rho[/math]. I am reading articles where the 'pressure' which makes the expansion data intelligible is indeed negative. So probably Martin or someone will take apart my arguments. That's cool, since nothing ventured nothing learned. I observe that we are certainly at the edge of many of our understandings, and we are humbled by the fact that maybe 90% of the constituents of the fields needed to complete a theoretic picture are, to our understanding, dark. In messing with what I see as a far-expansion, later universe (now and henceforth) I come up with the need for a vacuum having positive pressure but negative energy. We are not talking about free electromagnetic energy, we are talking about the virtual (?) essence of spacetime. All ideas must be tried here. Zephir, I read that for the model of a non-static universe with [math]\Lambda=0,~k=+1 [/math] it is inside a Schwarzschild radius.
  8. Thanks, coreview2. I wonder if this is why Honda is not continuing the Insight production. I am ready to go purchase something soon; what advice can folks offer? SH3RLOCK, it takes fuel to farm the corn.
  9. Reaper that's what I've heard.
  10. I apologize, I am not hip to your question.
  11. scalbers, can you help me understand the parameters in the abstract? Are they assuming symmetry with the proton?
  12. Last I read we see not much outside our galaxy, naked eye. This surprised me when I first learned it. Thus, our desire for telescopes. What sort of seeing are you thinking of?
  13. Polar bears are white. (Have you ever listened to the lyrics in that song? Yowsa.)
  14. Personally I don't care if we drift but there is excellent discussion offered by SH3RLOCK et. al. on ethanol. At one point I mentioned switchgrass and also jatropha as plants which could be grown on marginal land perhaps. I imagine freeways lined with producing rows. I live on marginal farmland good for grape vineyards and it seems this land would serve well. Maybe I am mixing modes here: one distinguishes between biofuel oil and hydrocarbons, and bacterial breakdown of simple or complex sugars to alcohol.
  15. Yah, scalbers, haven't I heard a term like secondary biofuels, or second generation or somesuch? This speaks of breakdown of cellulosic stuff. Just so we don't go stripping forest floors as is actually mentioned as not a good idea in the current Science News article, "Down With Carbon".
  16. Where is solar radio noise strong? The article speaks of visible, ultrav, and x range observing. What are they seeing??? I don't know much about the whole mix of physics going down here. I am but a purely theoretical physicist. [Purely _-_] I figured at first that this was a resonant phenomenon like electrostatic plasma oscillations which have a more intrinsic characteristic frequency, but it seems not.
  17. I have continued alternating weeks with AVAST and AVG. They seem to catch different items. It also seems, like the radio show mentioned, that the bad guys are winning..... As weeks go on, the setup download I need gets longer, so I just re-downloaded the whole most recent AVAST and will do the same when the AVG 8.0 comes around. Thanks for that 'heads-up'.
  18. I am trying to further my understanding of Alfven, hydromagnetic waves in a plasma. The analysis gives us a phase velocity dependent on magnetic field strength and plasma density. There seems to be no constraint on frequency, except for phenomenologic range. Is the statement that given any perturbation at frequency [math]\omega[/math], there is a damped propagation of inversely proportional wavelength, so the only constant constraint is the phase velocity?
  19. Try a different source.
  20. I am still in the same position, as I don't feel like paying another $75 to have it last only two days. Last weekend I was totally dead in the cyberwater for three days - could not get in or out. Then by itself, the next day I could. It was the weekend of Coptic Easter ????????? You tell me. . . . Today NPR describes hacking in China on most Chinese trying to make social or political statements.
  21. I was involved in an exchange last year over interpreting a small, positive cosmologic constant (CC, or [math]\Lambda[/math]). I tried to locate it but let's just start again. I say such a term corresponds to an intrinsic, positive pressure, such as I interpreted as manifest in the fractional photon population, or quantum zero-point field. I believe one of the blue-stars here dismissed this because the sign was wrong. I say not! The whole field equation reads: [math] {R^a}_b - \frac 1 2 R{g^a}_b + \Lambda {g^a}_b = - \frac {8\pi G } {c^2} {T^a}_b [/math] . When we construct the source terms on the right-hand side (RHS) the diagonals are:[math] <\rho c^2, -P,-P,-P>[/math] so the minus signs cancel. Thus a [math]\Lambda[/math] corresponds to positive intrinsic pressure. A good article in Science News, 2/2/8, "Embracing the Dark Side", quotes Steven Weinberg, U. Texas, Austin: "It's not too strong to say the 120 orders of mismatch between the quantum energy and the CC has been a bone in our throat for a long time. The problem is not why there is dark energy; the problem for physicists is why it is so incredibly small." The article continues: 'No one can explain why the energy density associated with the CC should have a magnitude comparable to the density of matter. "That's why I think a CC is pretty wacky," says Rocky Kolb of the U. of Chicago. "I refer to it as the cosmo-illogical constant." ' I have encountered quite a few people who tried to explain this away with statements like, oh, the energy zero level is not physical, only the changes in it. Like Weinberg, I say not. I see now the possible confusion (Severian, was that you?) One allows a positive [math]\Lambda[/math] on the LHS of the equation. This is saying, we observe such a stretching of the spacetime manifold. It is a mistake to simply move this to the RHS! The vacuum must have a physical characteristic to provide sourcing which balances the equation. What is DARK is our understanding. (In the mixed tensor expression [math] {g^a}_b[/math] the diagonal terms are all positive. When one starts constructing the stress-energy RHS, one writes [math] <\rho, P/{c^2}...>[/math] in a doubly covariant form. Then you raise one index and give the pressure (P) terms a minus sign. Sprinkle in [math]c^2[/math]'s as needed. )
  22. Ouch, developmental chaos as usual. Why are motorcycles not better? I loved my BMW R60 for four years. Then I needed all-weather real-life transport for myself and piano service tools. Back to the Insight, are they not coming out with a similar thing or are they caving in to the 45 mpg of the Civic? Design in the USA does not seem to be concerned about anything but the SUV and family needs. Last week a piano client called offering a nice piano for sale as he needed to downsize his living style. No kidding, there is a huge population wave needing somewhat the same thing! I am in the market for a small, efficient house, and a small, efficient autocar. . . . . I read in Wiki that battery replacement is becoming much easier, at maybe 150k total miles.
  23. Hybrids use electric motor assist, or even start solely on electric power. Importantly, they recover energy in slowing. I rode in a Prius and at easy throttle you came off stop on electric until some moderate speed, unless you stepped harder on the pedal. I want to know about the Honda Insight which gets like 60 mpg highway, as I could consider buying one. I see a couple of years ago they stopped making it and now I see their Civic at 45 mpg. Are they coming out with a replacement? I want 60 mpg for lightweight shopping and rural life. I remachined the engine in my Subaru Loyale '92 wagon for 30+ mpg with room for and load of piano tuning parts and tools, but more often I just would like to move around lightly.
