Nobody highlighted it, but the 5-year WMAP results were published on March,07 and results are stunning:
I long awaited this moment and, looking to results, we definitely entered in the "precision cosmology" age... (frankly, this goes well behind my hopes to see such accomplishments in my lifetime! ). Between the many foundamental determinations and refinements (which I hope will be discussed here), the most impressive result in terms of precision is the universe age, now known with less than 1% uncertain after joining WMAP estimation with other independent measurements: t0 = 13.73 + 0.12 Gyr It seems that, at this point, we know the age of universe with a relative precision comparable to Solar system age [from Wikipedia]: tss = 4.53 to 4.58 Gy Now, about these two ages, after previous WMAP release I was already disappointed by an intriguing coincidence, now confirmed by new estimation: t0 / tss = 3.014 + 0,043 So, within uncertain range, the ratio "is" exactly 3! I know that, to many, this is only a coincidence. Otherwise it would require that we live in a very special moment...and place! Even if a little bit mistic, this approach isn't new in the cosmology: think about anthropic principle and large numbers coincidences! Anybody wants to accept such provocation? -------------------- I always think before posting! - Marco -
