hi everyone, i definitely think we should respond to this - but i would prefer it to be a collective response - there's no reason why only my name should be cited - e.g., we could at least have the official "team"

I am SURE the data is not convincing. but people get excited even if there is only 1 sigma difference between theory and observations. theoretists have very little to do since everything matches perfectly and even 1 sigma is an event... in case of cmb and low multipoles - with a slightly different analysis it does not give such exciting results ;-)
regards - michal forgive me but I am quite sceptic about this all.
i didn't put the following in the text since it's too subtle for a general audience (requires explaining what spherical harmonics are etc), but Efstathiou's increased quadrupole value provides a better match to the Luminet et al quadrupole. :) Of course, the octupole increases above the Luminet et al value. :(
In any case, (1) our journalist contact has already had the article printed
pA11 Rzeczpospolita 15.10.2003 http://www.rzeczpospolita.pl/gazeta/wydanie_031015/nauka/nauka_a_1.html
and (2) he didn't include all our names and (3) he misspelt my first name.
However, given that he works for a "controlled" newspaper, what he finally printed is probably not too bad in terms of - except that the credit for our collective opinion all goes to me - how's that for an example of intellectual capitalism...
As for the real science, i've been in cosmology long enough to remember how many, many times cosmologists wrote similar words to "forgive me but I am quite sceptic about this all" about a non-zero cosmological constant. Until the years 1997-2000 when those people shrunk to a tiny minority (including at least one highly respected cosmologist).
Only when the results are really solid will we know one way or the other whether cosmic topology is still a useful subject...

Hipoteza Jeffreya Weeksa i Jeana-Pierre'a Lumineta jest bardzo interesuj?ca. Przyjmuj? oni za model wszech?wiata przestrze? dodekahedraln? Poincarego. Niestety, nie mamy jeszcze do?? danych, by stwierdzi?, czy hipoteza jest prawdziwa. To, ?e jest sp?jna, to za ma?o. Mo?na poda? przyk?ad innej idei, przedstawionej np. w pracy George'a Efstathiou (http://arXiv.org/abs/astro-ph/0310207), wed?ug kt?rej wszech?wiat jest du?o, du?o wi?kszy i niezakrzywiony. Ta hipoteza jest tak samo sp?jna jak przestrzeni dodekahedralnej Poincarego.
W Centrum Astronomicznym Uniwersytetu Miko?aja Kopernika przeprowadzimy analiz? hipotezy, korzystaj?c z tych samych danych. Wykorzystamy te? katalogi galaktyk radiowych i kwazar?w. B?dziemy bardzo zadowoleni, je?li hipoteza oka?e si? prawdziwa. Na razie sprawa jest otwarta. NOT. ?.K. ###
