Jean-Pierre Luminet (1951 - ) is a French astrophysicist, specialized in black holes and cosmology. He works as research director for the CNRS (Centre national de la recherche scientifique), and is a member of the Laboratoire Univers et Théories (LUTH) of the observatory of Paris-Meudon.
The asteroid 5523 Luminet, was named after him [1].
- 2003- An apparent periodicity in the cosmic microwave background led to the suggestion, by Jean-Pierre Luminet of the Observatoire de Paris and colleagues, that the shape of the Universe is a finite dodecahedron, attached to itself by each pair of opposite faces to form a Poincaré homology sphere. ("Is the universe a dodecahedron?", article at PhysicsWeb.)
The causality relation between this periodicity phenomenon in the cosmic microwave background and such a shape of the Universe appears to me a little bit too straightforward... But true that I don't know the arguments in detail.
ReplyDeleteBest,
People might tell you that I am not to be trusted as to the value of the science I put forward. Let me know if you feel this way too.

According to the team, who published their study in the 9 October 2003 issue of Nature, an intriguing discrepancy in the temperature fluctuations in the afterglow of the big bang can be explained by a very specific global shape of space (a "topology"). The universe could be wrapped around, a little bit like a "soccer ball", the volume of which would represent only 80% of the observable universe! (figure 1) According to the leading cosmologist George Ellis, from Cape Town University (South Africa), who comments on this work in the "News & Views" section of the same issue: "If confirmed, it is a major discovery about the nature of the universe".
Your on Tegmark's turf now:)
All old news that has been advanced.
Sean Carroll has taken over as to the universe's movement and its reasons "in the CMB."
You just had to know where and what to look at. "M87 jet" is always nice to prep the mind as to the universe's outcome in that shaping perspective. It is dynamical movement at it's best whether one likes to look at the whole of it while consider the local regions.

ReplyDeleteCorrected first link after trying.
Dear Plato
ReplyDeleteThanx for your contribution.
Infinity is Mathematics, not Physics, and it's no surprise to me that we finally come back to that idea.
Best,
