<content:encoded><![CDATA[<blockquote><p>Interesting article George, but I fail to see the relevance. The question was not about object expansion, but about relative positions of interstellar objects(Though I could conceivably see universal expansion leading to the expansion of the area of a gas cloud, it would not expand the molecules that form it, just the space between). The physics model on the wiki page I linked(which I had seen elsewhere in a lecture) clearly says that everything in the universe should be moving <em>away</em> from each other, not moving into a collision course at some point. So, ignore the shrinking/expanding celestial body thing for now (though that is interesting) and lets figure out how an interstellar body that should be moving ever further away from all surrounding interstellar bodies could be lining up for a collision course.-What article are you referencing here that is asking this question?  -Or are you talking about how we&amp;apos;re colliding with Andromeda?  If it&amp;apos;s that, that&amp;apos;s simply gravity doing its job.  -http://www.scientificamerican.com/article.cfm?id=how-can-galaxies-collide</p>

<content:encoded><![CDATA[<p>Look for FLRW model:-http://en.wikipedia.org/wiki/Shape_of_the_Universe-&amp;quot;The curvature of space is a mathematical description of whether or not the Pythagorean theorem  is valid for spatial coordinates. In the latter case, it provides an alternative formula for expressing local relationships between distances:-    * If the curvature is zero, then &amp;#206;&amp;#169; = 1, and the Pythagorean theorem is correct.&amp;#13;&amp;#10;    * If &amp;#206;&amp;#169; &gt; 1, there is positive curvature, and&amp;#13;&amp;#10;    * if &amp;#206;&amp;#169; &lt; 1 there is negative curvature;-in either of these cases, the Pythagorean theorem is invalid (but discrepancies are only detectable in triangles whose sides&amp;apos; lengths are of cosmological scale).-If you measure the circumferences of circles of steadily larger diameters and divide the former by the latter, all three geometries give the value &amp;#207;&amp;#128; for small enough diameters but the ratio departs from &amp;#207;&amp;#128; for larger diameters unless &amp;#206;&amp;#169; = 1:-    * For &amp;#206;&amp;#169; &gt; 1 (the sphere, see diagram) the ratio falls below &amp;#207;&amp;#128;: indeed, a great circle on a sphere has circumference only twice its diameter.&amp;#13;&amp;#10;    * For &amp;#206;&amp;#169; &lt; 1 the ratio rises above &amp;#207;&amp;#128;.-Astronomical measurements of both matter-energy density of the universe and spacetime intervals using supernova events constrain the spatial curvature to be very close to zero, although they do not constrain its sign. This means that although the local geometries of spacetime are generated by the theory of relativity based on spacetime intervals, we can approximate 3-space by the familiar Euclidean geometry.&amp;quot;-WMAP suggests that the universe is flat--observation is within 2% of what we would expect a flat universe to look like.  There are a few other geometries suggested that also map to this, but they are more complex, and therefore not favorable candidates.</p>

<content:encoded><![CDATA[<blockquote><blockquote><p>No. The curvature is based on objects in the way such as galaxy lensing which is used all the time to make observations that would otherwise not be available. Mass bends space and light. In looking at the CBWR 300,000 years after the Big Bang, there are all sorts of bodies between us and the point  you want to fix. So, over that distance, there would be left-handed and right-handed curves that need not cancel out. One would have to account for each one to have a valid fixed point, which would be moving all the time. George is right. Euclidean geometry doesn&amp;apos;t work out there. Everyone accepts that, and you need to.&amp;#13;&amp;#10;&gt; &amp;#13;&amp;#10;&gt; Yes, you have to take curvature, rate of change, and other variables into account when mapping in space. There was NEVER any argument about that. Hell, even here on earth when mapping areas many kilometers beneath the sea floor we have to take into account density, temperature, pressure, salinity, the makeup of different geological layers, porosity, reflective etc etc etc. Please don&amp;apos;t be insulting to my intelligence. My point is that they either CAN account for it, or they CAN&amp;apos;T. Secondly, the term &amp;apos;Euclidean&amp;apos; geometry has not once escaped my lips in this conversation, nor was it even implied other than in the context of defining a spatial origin from which to start. Even when kicking this idea around over coffee I never dreamed that it would be a simple straight line measurement. There IS limited linear movement in space, but that has nothing to do really with the matter of defining a set of spatial coordinates.-Yes it does:  you would need to define a start point and end point, therefore a discussion of spatial coordinates is essential, as it would need to be accurate.</p>

<content:encoded><![CDATA[<blockquote><p>I&amp;apos;ve seen some of George&amp;apos;s math and have no doubts as to his mathematical prowess. The point is, if physicist are able to determine that space is expanding in three dimensions with curved space time in between, as they claim, then they must have a way of accounting for the curvature of said space time. If they do not, then they can not say that space is expanding in three dimensions with curved space time in between. &amp;#13;&amp;#10;&gt; &amp;#13;&amp;#10;&gt; This is what strikes me as the fundamental flaw in the argument. Either they can account for it, and thus their assertions about expanding space are true, or they can not account for it and their assertions about expanding space are, while perhaps true, based on unprovable assumptions.-They account for it using math... I don&amp;apos;t see where your argument is.  The picture of the background that everyone has looked at is taken via the equivalent of an absolutely gigantic fishlens camera and turned into the image you&amp;apos;ll see all over google images if you search for it.  -It&amp;apos;s accounted for.</p>

<content:encoded><![CDATA[<p>Balance,-I&amp;apos;m rather late to this discussion, but I think I can answer this question for you relatively quickly, although it shames me that your physicist friend did not discuss this:-Time is relative (via Einstein.)  Space and time are also equal to each other. -Our universe is infinitely expanding; therefore as time grows, so does space.  And, all things in it are moving---our earth, our sun, and our galaxy are all in motion;  it is simply <em>not possible</em> to ever be completely still in order to satisfy that requirement of your experiment.  You could be still in relation to the sun, but the influence of the Milky Way would exert its influence on your experiment.  -If you wonder about this, look up &amp;quot;gravitational lenses.&amp;quot;  Light cannot help but be influenced by gravity.-[EDIT]-You would have to be so distant... so remote... that no force <em>anywhere</em> could influence you.  You would have to find a point somewhere in the universe where all gravitational forces cancel each other out... perhaps wherever our bang went big... and conduct your experiment there.  But, <em>even then</em> your experiment would have error.</p>

Gravity is a <a href="http://library.thinkquest.org/27930/forces.htm">weak force</a>. In fact, it is the weakest of the four fundamental forces. But, are there four fundamental forces, or three? Being that all matter is made up of atoms with positive/negative charges, it is very possible that <a href="http://www.superconductors.org/gravity.htm">gravity is a subset of electromagnetism</a>. Einstein died working on that unified theory and many others have tried failed. -<img src="http://upload.wikimedia.org/math/6/2/f/62f32e173125bf365adb20f640570122.png" alt="[image]" />-&amp;#13;&amp;#10;<em>&amp;quot;The gravitational force is extremely weak compared with other fundamental forces.

Both these forces are weak when compared with the forces we are able to experience directly, but the electromagnetic force in this example is some 39 orders of magnitude (i.e. 1039) greater than the force of gravity &amp;#226;&amp;#128;&amp;#148; roughly the same ratio as the mass of the Sun compared to a microgram mass.&amp;quot;</em>-The point is, gravity could not have done what is being claimed of it, especially with objects moving at exceptionally high rates of speed, with exponentially increasing distance between them.

<content:encoded><![CDATA[<p>Woody Allen has the answer to this one!-Is Brooklyn Expanding?&amp;#13;&amp;#10;In Annie Hall, the movie character played by the young Woody Allen explains to his doctor and mother why he can&amp;apos;t do his homework. &amp;quot;The universe is expanding. The universe is everything, and if it&amp;apos;s expanding, someday it will break apart and that would be the end of everything!&amp;quot; But his mother knows better: &amp;quot;You&amp;apos;re here in Brooklyn. Brooklyn is not expanding!&amp;quot;-His mother is right. Brooklyn is not expanding. People often assume that as space expands, everything in it expands as well. But this is not true. Expansion by itself--that is, a coasting expansion neither accelerating nor decelerating--produces no force. Photon wavelengths expand with the universe because, unlike atoms and cities, photons are not coherent objects whose size has been set by a compromise among forces. A changing rate of expansion does add a new force to the mix, but even this new force does not make objects expand or contract.-For example, if gravity got stronger, your spinal cord would compress until the electrons in your vertebrae reached a new equilibrium slightly closer together. You would be a shorter person, but you would not continue to shrink. In the same way, if we lived in a universe dominated by the attractive force of gravity, as most cosmologists thought until a few years ago, the expansion would decelerate, putting a gentle squeeze on bodies in the universe, making them reach a smaller equilibrium size. Having done so, they would not keep shrinking.-In fact, in our universe the expansion is accelerating, and that exerts a gentle outward force on bodies. Consequently, bound objects are slightly larger than they would be in a nonaccelerating universe, because the equilibrium among forces is reached at a slightly larger size. At Earth&amp;apos;s surface, the outward acceleration away from the planet&amp;apos;s center equals a tiny fraction (10^-30) of the normal inward gravitational acceleration. If this acceleration is constant, it does not make Earth expand; rather the planet simply settles into a static equilibrium size slightly larger than the size it would have attained.-This reasoning changes if acceleration is not constant, as some cosmologists have speculated. If the acceleration itself increased, it could eventually grow strong enough to tear apart all structures, leading to a &amp;quot;big rip.&amp;quot; But this rip would occur not because of expansion or acceleration per se but because of an accelerating acceleration. -The above is from:&amp;#13;&amp;#10;http://www.scientificamerican.com/article.cfm?id=misconceptions-about-the-2005-03&amp;page=5</p>

If we could see microwaves, the entire sky would glow with a brightness that was astonishingly uniform in every direction.&amp;#13;&amp;#10;&gt; &amp;#13;&amp;#10;&gt; B-M appears to think the Background is the &amp;quot;edge&amp;quot; of a &amp;quot;present&amp;quot; spherical three-dimensional universe within which we are situated.-For all practical purposes, time is simply another axis along which we measure, 4 dimensions instead of 3. Additionally, time, much like space, can be compensated for mathematically, and in fact must be accounted for in some fashion all but the simplest of equations. No, the universe is not(most likely) a sphere, ellipsoidal perhaps, but not likely spherical. However, even if it were tetrahedral or a parallelogram or any other deformation you can conceive of, the concept could still work, even if it required measurements along more axis. And while we are looking back in time, we are also looking across distance. Can you at least concede that the universe, based on the fact that we can see the CMBR throughout the whole of the sky, must be limited(even if it is expanding), and if it is limited, it will contain properties such as volume and boundaries?</p>

<content:encoded><![CDATA[<p>I&amp;apos;m only coming back here very occasionally so don&amp;apos;t count on any quick replies.-In the original post B-M wrote: &amp;quot;If you measure the time it takes for readings from the CMRB to reach a given point, then work backwards to a point where the time from CMRB X+,Y+,Z+ = X-,Y-,Z- you should have origin=X,Y,Z =0 which gives you a universal frame of reference.&amp;quot;-This appears to be a misunderstanding of what the CMBR is.
