		<description>Fool!

The earth is flat and is 6000 years old.
The sun, which is 1/2 the size of the earth orbits in a perfect circle around the earth.
The moon which is 1/2 the size of the sun orbits the sun and the earth.

Oh, yeah and in the end of days a giant seven headed snake will come out of noware and brand 666 on everyones head! :-)

Watch out for Poes Law!</description>

		<description>Lawrence,

Thanks again.

&lt;blockquote&gt;&quot;I’m a Platonist &#8212; a follower of Plato &#8212; who believes that one didn’t invent these sorts of things, that one discovers them. In a sense, all these mathematical facts are right there waiting to be discovered.&quot;Harold Scott Macdonald (H. S. M.) Coxeter&lt;/blockquote&gt;

Moving to polytopes or allotrope seem to have values in science? Buckminister Fuller and Richard Smalley in terms of allotrope.

I was looking at Sylvestor surfaces and the Clebsch diagram. Cayley too. These configurations to me were about &quot;surfaces,&quot; and if we were to allot a progression to the &quot;projective geometries&quot; here in relation to higher dimensional thinking, &quot;as the polytope[E8]&quot;(where Coxeter[I meant to apologize for misspelling earlier] drew us to abstraction to the see &quot;higher dimensional relations&quot; toward Plato&#039;s light.)

As  the furthest extent of the Conjecture ,  how shall we place the dynamics of Sylvestor surfaces and B Fields in relation to the timeline of these geometries? Historically this would seem in order, but under the advancement of thinking in theoretics does it serve a purpose? Going beyond &quot;planck length&quot; what is a person to do?

Thanks for the clarifications on Lagrange points. This is how I see the WMAP.

&lt;blockquote&gt;&lt;a href=&quot;http://map.gsfc.nasa.gov/m_ig/990529/990529b.jpg&quot; title=&quot;Lagrange point 1-5 of Sun Earth relation&quot; rel=&quot;nofollow&quot;&gt;Diagram of the Lagrange Point&lt;/a&gt; gravitational forces associated with the Sun-Earth system. WMAP orbits around L2, which is about 1.5 million km from the Earth. Lagrange Points are positions in space where the gravitational forces of a two body system like the Sun and the Earth produce enhanced regions of attraction and repulsion. The forces at L2 tend to keep WMAP aligned on the Sun-Earth axis, but requires course correction to keep the spacecraft from moving toward or away from the Earth.&lt;/blockquote&gt;

Such concentration in the view of Sean&#039;s group of the total WMAP while finding such a concentration would be revealing would it not of this geometrical instance in relation to gravitational gathering or views of the bulk tendency? Another example to show this fascinating elevation to non-euclidean, gravitational lensing, could be seen in this same light.

Such mapping would be important to the context of &quot;seeing in the whole universe.&quot;</description>

		<description>Plato on Jun 11th, 2008 at 12:51 am

I am currently trying to learn to understand the Poincare Conjecture and the lessons in this are amazing to me.
------------

...  as I have detailed them in &quot;satellite travel above&quot; and in terms of Lagrangian points
----------------------

The Poincare homology sphere is related to his conjecture.  Yet the homology sphere is a sphere with the rotational group SO(3) &quot;modulo&quot; a discrete set of rotations which describe a polytope or polyhedra.  The homology sphere is a boundary of a region of four dimensions with a quaterionic structure.  If the four manifold is a 4-sphere then the 3-homology sphere bounds both of then and there is then a quaternionic structure in the whole 4-space.  At the time Poincare worked on these matter, in the late 19th century, quaterions were a &quot;hot item.&quot;  Indeed Maxwell originally formulated his EM equations according to quaterions.

Lagrange points are regions where the Newtonian gravitational forces from two main bodies and centripetal force on a third &quot;test mass&quot; cancel out.  For the Earth and sun alone these are fixed points.  The L_1, L_2 and L_3 points have potential functions (in the accelerated frame) which are saddle point configurations, and are thus not stable, but quasistable.   Another problem is that there is a perturbation due to the moon, so the Lagrange points are not fixed points, but wobble around in Lissajous orbit.

So to get there is tricky.  The craft is placed in a highly elliptical orbit that approaches the Lagrange point.  The RTG on the craft then after 3 passes nudges the craft into the Lagrange points.  Also, since the Lagrange point is a saddle potential one needs to perform station keeping to maintain a &quot;trim&quot; on the orbit.  This requires occassional rocket burns.  This will continue until Sept 2009, after which WMAP will go silent and become &quot;lost in space&quot; as space junk.  The Planck spacecraft will be launched later this year and will provide better data, including measurements of B-mode polarizations.

Astro-navigation is a bit like golf, you have a certain par for a mission and the objective is to get the ball in the hole, craft to its orbit, libration point, planet etc.

		<description>Re: #8  &quot; that this &#039;lop-sidedness&#039; cannot be explained by Gaussian statistics?&quot;

Recent observations and analysis by Benjamin Wandelt indicate (just below the level where they announce &quot;detection&quot; in the forthcoming Phys Rev Letters but instead say &quot;evidence for&quot;) &quot;non-gaussianity&quot; in the CMB.

This earlier paper by Yadav and Wandelt claims ‘detection’:

* Amit P. S. Yadav and Benjamin D. Wandelt, Detection of primordial non-Gaussianity (fNL) in the WMAP 3-year data at above 99.5% confidence.

Their abstract finishes with: &quot;We conclude that the WMAP 3-year data disfavors canonical single field slow-roll inflation.&quot;

This may be the start of the collapse of Alan Guth’s &quot;inflation&quot; – the unifying principle of Cosmology since Big Bang.

What, Dr. Sean Carroll, should we focus on in relating your theories and this data interpretation?</description>

Ah. Sorry, I misinterpreted your question to mean are there better minds (on other blogs or forums for example) than the blog authors here!

I must say it did seem a somewhat implausible thing to ask, and perhaps I should have read between the lines; but it just shows how easily a &quot;discursive&quot; writing style (using as nice a word as possible) can be misunderstood ;-)</description>

		<description>The idea to me of&quot; time reversals&quot; had to have some inclination to include Gr at the inception of a new universe, or, of connecting the &quot;beginning and end&quot; in the very nature of this universe now.

Where is Zero point entropy? Does it exist in any positions in our universe that would be considered the place where such beginning and ends make then self known?

What would be the physics of this place?

I am thinking in my layman mind that it is contained in the &quot;moment of the collision process&quot; where we are experimentally moving to words a &quot;supersymmetrical view.&quot; Navier Stokes equations are then considered and the viscosity then provides for this opening to &quot;time reversal and such?&quot;

 Of course I am all over the map:) But to me such a concentration of  of gravity in my views of the universe belong to the idea  that a gravity perspective is now contained in the &quot;bulk view.&quot;</description>
