![]() "Joe" wrote in message oups.com... "The universe is everything" to a closed minded person like you. Space that the universe is expanding into exist before our universe expands into it. http://imagine.gsfc.nasa.gov/docs/as...s/011021a.html : "Perhaps the simplest way to look at these questions is the following: if the universe includes, by definition, everything -- all of space, time, matter, energy -- than there can be nothing outside of it (and hence no edge), nothing for it to expand into. Its true that this is contrary to our everyday experience, as is much else in physics and astronomy; but of course our everyday experience does not extend to the entire universe. In some ways this line of argument parallels those in refutations of the "argument by design" for the existence of God." http://www.astro.ucla.edu/~wright/co...y_faq.html#XIN : What is the Universe expanding into? This question is based on the ever popular misconception that the Universe is some curved object embedded in a higher dimensional space, and that the Universe is expanding into this space. This misconception is probably fostered by the balloon analogy which shows a 2-D spherical model of the Universe expanding in a 3-D space. While it is possible to think of the Universe this way, it is not necessary, and there is nothing whatsoever that we have measured or can measure that will show us anything about the larger space. Everything that we measure is within the Universe, and we see no edge or boundary or center of expansion. Thus the Universe is not expanding into anything that we can see, and this is not a profitable thing to think about. Just as Dali's Corpus Hypercubicus is just a 2-D picture of a 3-D object that represents the surface of a 4-D cube, remember that the balloon analogy is just a 2-D picture of a 3-D situation that is supposed to help you think about a curved 3-D space, but it does not mean that there is really a 4-D space that the Universe is expanding into. http://www.sciam.com/askexpert_quest...88F2D7&catID=3 : "There is no 'empty space' that the universe is expanding into." Wrong. They are in motion... not you. They do not see you moving, they see the effects of the engine pulling the train Here's a quote from Einsteins paper on Special Relativity: .... the introduction of a light-ether will prove to be superfluous since, according to the view to be developed here, neither will a space in absolute rest endowed with special properties be introduced nor will a velocity vector be associated with a point of empty space in which electromagnetic processes take place. .. What is the absolute reference frame for all motion in the universe? The center or origin. ------------Check the implications of the "Cosmological Constant". Quick Navigation Quick Nav Menu Home Search Status News Technical Site Map Links Glossary Image Gallery About MAP What is a Cosmological Constant? Einstein first proposed the cosmological constant as a mathematical fix to the theory of general relativity. In its simplest form, general relativity predicted that the universe must either expand or contract. Einstein thought the universe was static, so he added this new term to stop the expansion. What you and other fail to understand is that this was an unstable fix, like balancing a pencil on its point. Now we have an expanding universe model, now called the Big Bang theory. When Hubble's study of nearby galaxies showed that the universe was in fact expanding, Einstein regretted modifying his elegant theory and viewed the cosmological constant term as his "greatest mistake". What is the physical significance of the CC? - Hide quoted text - - Show quoted text - The law of inertia describes perpetual motion. In fact, the motion is perpetual if no energy is added or removed from the system. See above...the key is nothing added or removed. It requires energy to put anything in motion therefore it is not perpetual. Motion is relative. The energy could be applied to the observer, not the observed to change the apparent motion .. apparent motion is not motion. Where does the energy come from to induce additional rotation in the Lens-Thirring effect? The rotation field, whether caused by a linearly moving mass or a rotating object, only affects moving masses. What kind of field is produced by this rotation? Since the field is rotating are all masses not rotating with it considered moving ? Gravity, & yes ---------------Most claim gravity is a quadripole field and rotating masses do not produce additional gravitational fields. Could the field be a time distortion instead? No. Recent satellite experiments have shown frame dragging in low earth orbit. The time distortion is dependent of the velocity of the satellite relative to the earth's surface. http://einstein.stanford.edu/content...de/Page28.html says: One of the predictions of Einstein's general theory of relativity is that local spacetime is twisted by the rotation of the Earth. Hans Thirring and Joseph Lense called this "frame-dragging"- any rotating mass will drag the local spacetime frame of reference Honey Ball Drawing with it. The predicted drag is very small and fades as one travels farther from the rotating mass, but the twist nearby can affect the paths of light, energy, and other masses. |

So what instruments would you use to measure this?
"Joe" wrote in message oups.com... Thats easy Hank, Curvature can be measured entirely within a surface, and similarly within a higher-dimensional manifold such as space or spacetime. On earth, if you start at the North Pole, sail south for about 10,000 km (to the Equator), turn left by 90 degrees, Sail for 10,000 more km, and then do the same again (sail for 10,000 more km, turn left by 90 degrees, sail for 10,000 more km), you will be back where you started. Such a triangle with three right angles is only possible because the surface of the earth is curved. The curvature of spacetime can be evaluated, and indeed given meaning, in a similar way. Spaces of only two dimensions, however, require only one quantity, the Gaussian or scalar curvature, to quantify their curvature. In more dimensions, curvature is quantified by the Riemann tensor. This tensor describes how a vector that is moved along a curve parallel to itself changes when a round trip is made. In flat space the vector returns to the same orientation, but in a curved space it generally does not. Joe |

Here's a quote from Einsteins paper on Special Relativity:
.... the introduction of a light-ether will prove to be superfluous since, according to the view to be developed here, neither will a space in absolute rest endowed with special properties be introduced nor will a velocity vector be associated with a point of empty space in which electromagnetic processes take place Einstein was wrong. The introduction of a light ether is not superfluous. He just failed to consider the real physical property's of massless energy. We know the universe is expanding. Therefore there is space for it to expand into, a space packed full of Juju. While I was working on a theory of the magnetism of dielectrics I came across some surprising results.. like their ability to make RedClouds magnetic compasses spin at high speeds. Einstein's unified and general theories had literally banned any systematic analysis of physical nature in exchange for a theory of topology, not even geometry or metrics. Joe |

Me to, and they gave you quite a sugar buzz. However that is not where
I came up with the name for the cosmic energy source I discovered. Yet it did come from a movie. A Tarzan movie, the natives were scared ****less of Juju, a mystical power the tribe feared and respected. Joe |

A random dataset could appear to be ordered to us, and we would be
none the wiser. That's why experiments must be reproducable. Wally wrote: Still doesn't address the underlying problem that the notion of causality is no more than an inference wrought of the empire of our experience. That's true enough. But here's where the difference between "science" and philosophy creeps in... when it's science, it happens every time. For example, the phenomenon of water flowing downhill is essentially a random event, the illusion caused by trillions of odd-shaped molecules bouncing around any way they want. But somehow, water *always* flows downhill. Fresh Breezes- Doug King |

I've seen water come off a fall and be blown up into the air. I'm quite
sure some evaporated and rose to the clouds. Hmmmmmmmm Joe |
