The only reason you have to ask for supercomputer time (and complain when you don't get it) is to avoid doing the work yourself! CPU power is no longer the scarce resource it once was. Today CPU power is ubiquitous - that's why people are asked to donate CPU time from their private computers in projects like seti@home. But most CPU power of today is used in idle cycles, or to draw pretty images on people's computer screens. You cna use your own CPU power differently if you want - for instance by running those simulations you're asking for. What are you waiting for? Go ahead !!! In other Paul Schlyter words, whatever you do, no matters what never help Einstein or anyone else. Now I get it. Einstein worked out his theories by himself - he couldn't count on others to do his work for him.... I'll look for that fully 3D interactive orbital software that'll do 5 body solutions on the fly, so to speak. Got any recommendations? Yep - personally, I'm very fond of Steve Moshiers de118i software. It's free and the source code is available too. You can find it he http://www.moshier.net/ssystem.html I've used it myself for almost 2 decades now, and it works really fine. It's fully 3D as you request (btw any decent orbit simulator *must* be "fully 3D", since orbits are "fully 3D" - i.e. a simulator which is only "2D" or "partial 3D" (whatever that means) won't be able to accurately simulate real "fully 3D" orbits). It can integrate an arbitrary number of bodies - the constraints are set by the resources of your computer and, in case you'd want to integrate hundreds of bodies at the same time, also your patience. It comes with initial parameters for 13 bodies in our solar system: the Sun, the planets, our Moon, Pluto, and Ceres, but you can easily modify the number of bodies and the initial parameters of each body to suite your own needs. However, it comes as C source which you must compile and run yourself. And you must edit the code too if you want to use initial parameters different from the supplied ones. Dunno how much of an obstacle this is to you, but if you know at least some basics of software development, and if you can handle a C compiler, you should find de118i a very useful tool. It produces very accurate results. If you lack the needed skills, it shouldn't be too hard to learn them, if you're seriously interested. And, yes, it runs fine off your laptop too. Integrating just 5 bodies isn't much.... Good luck! Can you suggest any other off-world source of stellar energy that has a period of roughly 105,000 years? I'm not aware of any such source with such a precise period. The best you could hope for is a few nova explosions in the solar vicinity which just happened to occur with that period. But would they be "slow novas" and happen over and over? (I don't think so) How many cycles do you require? Two? Three? A dozen? Hundreds? Of course nova explosions which by random chance happened at seemingly regular times in the past are extremely unlikely to repeat in the future. But just stay calm - if this is the process, you won't live 105,000 years in the future to see it fail then.... :-) How about Sirius B going slow-nova every 105,000 years (more frequently in the past)? That's not a known stellar mechanism. I tend to agree. Certainly our sun is not what's from time to time going postal on us, is it? It's much more likely than Sirius B doing the same thing, since a much smaller variation in the solar output would be required to have any effect on the Earth. Thus far, no such stellar physics can support that analogy, unless the sun was being systematically impacted by at least a Jupiter mass every 105,000 years. .....and how did you arrive at "by at least a Jupiter mass" ???? And why do you so causally dismiss the possibility of internal processes within the Sun? Do you already know completely how the Sun works? g A much closer orbit of our moon could certainly have an impact, going from 2e20 N to the half distance becoming worth 8e20 N. Now that would certainly be weird and unlikely. ~ BG One thing you seem to completely neglect is internal mechanisms in the Earth and its atmosphere. Changes in the atmospheric circulation with approximately this period? Huge volcanic eruptions which happened to occur at these times? Or perhaps changes in the orbital parameters of the Earth - i.e. Milankovic cycles ??? That's not exactly true, as I've many times questioned where the 2e20 N/sec of tidal force from Selene is going, and what is it doing to our 98.5% fluid Earth. Do you know? It's slowly slowing down the rotation of our Earth, and at the same time moving the Moon further out in its orbit. Eventually, a balance will be reched where the Earth's day and the lunar month will have the same length, at some 40 of our present Earth days. Then the Earth and the Moon will be tidally locked to one another, and neither the day nor the month will then get any longer. However, this will take some billion years, and probably the Sun will become a red giant before that, possibly vaporizing both the Earth and the Moon. Btw I'm somewhat surprised that you didn't know this already..... Do you happen to know of when and how Earth got its seasonal tilt? A very long time ago - probably back when some large body passed very near the Earth, ripping out a significant part of it which later became our Moon. We're talking about several billion years into the past. It could have happened fairly shortly after the Earth condensed as a planet out from the primeval nebula of our solar system. And, no, I cannot supply the precise year and date.... :-) btw, +/- 10 w/m2 isn't likely as based upon solar performance alone, especially by way of our passive sun that's hardly aging by any rate that could possibly matter. ~ BG But the Sun orbiting Sirius (or their common barycenter), or Sirius B going nova every 105 kyears? ....no....No.....NO !!!!!! -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stjarnhimlen dot se WWW: http://stjarnhimlen.se/ -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stjarnhimlen dot se WWW: http://stjarnhimlen.se/ |

Not a mere 10:1 but infinity:1 i.e. a parabola. Escape velocity means just that: the velocity exceeds the parabolic orbital velocity. If you want the body to remain in an elliptical orbit, no matter how large the eccentricity of the ellipse is (although it must of course be less than one), the velocity must still be lower than the escape velocity.

In almost all real orbits, those factors are quite negligible. Therefore few if any orbital simulation software include them. They become important only for extremely small "planets", such as dust particles in cometary tails -- and if you want to investigate the tails of comets, only five dust particles are far from enough. Consider for instance the Sun and the Earth. The radiation pressure from the Sun upon the Earth amounts to some 2.2E+9 Newtons - that's equivalent to the weight of some 224 thousand tonnes at the Earth's surface. That may seem to be a lot by human standards, but it's miniscule compared to the gravity from the Sun upon the Earth, which amounts to some 3.6E+22 Newtons. Yep, that's some 1600000000000000 times stronger than the radiation pressure from the Sun. In fact, the radiation pressure from the Sun upon the Earth is so small that its influence upon the Earth's orbital motion is undetectable even by our best techniques today - and it will remain undetectable for quite some time to come. You're also asking about electromagnetic forces between the Sun and the planets. They too are negligibly small when considering the orbital motions of the planets. They certainly do affect the very thin gases and plasmas out in space, sometimes giving us e.g. beautiful auroral displays. But they don't affect the Earth's orbital motion in any noticeable way. So the orbital software does not include radiation pressure or electromagnetic forces, for a very good reason: these forces are negligibly small in our solar system. However, since the source code for the DE118i software is available, you're free to modify it to include these forces, if you think the effort would be worthwhile. Again, I wish you good luck.... and I sincerely do hope that you start working on your simulations now, instead of just inventing new evasive comments all the time.... -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stjarnhimlen dot se WWW: http://stjarnhimlen.se/ |

Changes in the atmospheric circulation with approximately this period? Huge volcanic eruptions which happened to occur at these times? Or perhaps changes in the orbital parameters of the Earth - i.e. Milankovic cycles ??? That's not exactly true, as I've many times questioned where the 2e20 N/sec of tidal force from Selene is going, and what is it doing to our 98.5% fluid Earth. Do you know? It's slowly slowing down the rotation of our Earth, and at the same time moving the Moon further out in its orbit. Eventually, a balance will be reched where the Earth's day and the lunar month will have the same length, at some 40 of our present Earth days. Then the Earth and the Moon will be tidally locked to one another, and neither the day nor the month will then get any longer. However, this will take some billion years, and probably the Sun will become a red giant before that, possibly vaporizing both the Earth and the Moon. Btw I'm somewhat surprised that you didn't know this already..... I'm not nearly as all-knowing as yourself, One need not be all-knowing" to know that! It belongs to be basics of solar system dynamics.... but then I don't believe 90% of what our government or their faith-based puppet-masters have to say. How many lies upon lies has your government and faith-based partners perpetrated? So far I've obtained no astronomical info at all from any government. Are you a paranoic conspiracy theorist, or what? In our beloved nation of misinformed parrots, borgs and educated mindless idiots, if it doesn't have the NASA stamp of approval on it, it isn't worthy science. What I do know is that 2e20 N/sec is a lot of tidal radius binding force that's keeping our Selene/moon associated with Earth, as it's continually distorting the crust of Earth by 55 cm, Did you learn that from the "lies by your government"? evil grin Of course not. Our extremely evil grin government wouldn't dare bother to inform the general public of what our Selene/moon has been doing to us. Until I'd searched for such information, I too never realized what was going on with having 7.35e22 kg orbiting so nearby. not to mention rather nicely motivating everything within our crust. Make that "moving" rather than "motivating". Motivation requires consciousness, so you cannot "motivate" dead matter.... Point well taken, though exactly how inert or dead is the matter within Earth? (not very) But the Sun orbiting Sirius (or their common barycenter), or Sirius B going nova every 105 kyears? ....no....No.....NO !!!!!! You're just no fun at all. For once, you're quite right! True, I'm not joking at all here, I'm dead serious.... You should stop being so "dead serious", perhaps because it's making your butt-crack way too tight. Once in a while you and most everyone else of your mainstream status quo needs to brake wind, or else. ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG / Guth Usenet |

snip Whether man made global warming is true or not is immaterial in the American context: It gives us enormous pleasure to know that the largest abuser of dwindling energy reserves pays many times over for every barrel. First it pays its despotic enemies over the top for the oil knowing that the customer is not remotely respected. Then it pays for a second time for the security measures to keep the oil reserves safe. It pays for a third time for the massive security measures to protect itself from the citizens/terrorists who aren't allowed even a tiny stake in the fabulous wealth oil generates for the dictators. It pays for a fourth time to fight illegal wars in the hope of getting its hands on cheap oil. It pays for a fifth time in the loathing and disgust with which America is held by the civilised world. It pays for a sixth time in the loss of revenue to health and social security services which would help its citizens live safe and comfortable lives. It pays for a seventh time when the oil rich nations buy up its important property, businesses and service industries cheaply using money given them by America. It pays for an eighth time in the ill health the oil causes in smog and pollution. It pays for a ninth time in the despoiling of the seas by corrupt businesses carrying the oil at least cost and highest profits by employing non-American sailors and staff. It pays for a tenth time for the lack of timely investment in alternative energy sources. It pays for the eleventh time reducing global warming while still employing century old technologies. It pays a twelfth time for the loss of productivity while workers sit in cars in traffic jams despite the massive investment already made in roads. It pays for a thirteenth time for the loss of lives due to present transport systems and the wasteful policing of them. It pays for the fifteenth time for the interest rates it pays on borrowing to buy the foreign oil in the first pace. It pays a sixteenth time for the damage done to the beauty of unspoilt coasts and countryside by oil exploration. It pays for a seventeenth tie in the national stress of electing losers as their representatives knowing they cannot reduce the price of gas at the pumps or oil for home heating. It pays for an eighteenth time in importing cars which people actually want to drive instead of what is offered by their time-locked, early 20th century car makers. It pays for a nineteenth time in making the roads unfit, unhealthy and unsafe places for walkers, joggers and cyclists. It pays for a twentieth time in all the things it cannot afford to do because it is sucking the planet dry of oil it can no longer pay for with cash. Etc, etc, etc, etc. |
