"The determination of the age of the Universe is one of the most important, but most difficult, problems in modern astronomy. In standard models, the age of the Universe depends primarily on the present rate of expansion (measured as the Hubble constant) and deceleration rate, which is determined by the total mass in the Universe."
p. 111
"At face value, Butcher’s excellent data show no decay at all in the Th/Nd relative abundance. This implies a short age scale, with the oldest stars being no more than 12 Gyr, rather than 18 Gyr old. The absence of any change in the ratio is surprising, and suggests that careful consideration of the relative production histories of r- and s- process elements is necessary. If the conclusion is correct, however, the implications are profound. Not only is the currently accepted physics of stellar evolution incomplete, but the Universe may be substantially younger than presently believed."

"The Hubble constant has a direct bearing on the age of the Universe because the faster it is expanding, the less time it must have taken to reach its present size since the big bang, and so the younger it must be. A high value—about 70—suggests the Universe is younger than its oldest stars, a logical contradiction that would destroy the big bang theory."
p. 22
"In the past five years, however, many younger and formerly uncommitted astronomers, using new techniques, have swung towards the ‘high’ side, supporting de Vaucouleurs."
pp. 22-23
"But how can both sides use ‘reliable methods’ to reach such widely different conclusions? And what constitutes a ‘reliable method’? The Canadian astronomer Sidney van den Bergh frequently writes reviews that try to sort out the mess, and is aligned with neither side. One that he wrote last year began with a quote from Mark Twain: ‘The researches of many commentators have already thrown much darkness on this subject, and it is probable that, if they continue, we shall soon know nothing at all about it.’"

"In principle trigonometric parallax is one of the simplest astronomical measurements, with little room for error or misinterpretation. But astronomers differ on how to correct their results for a host of effects, from the Hipparcos satellites’ sensitivity limits to the reddening of starlight by intervening dust."
p. 45
"A Cepheid’s pulsations are regulated in part by the opacity of its atmosphere; in turn, the opacity depends on the star’s complement of heavy chemical elements, or ‘metals.’ As a result, two Cepheids with identical pulsation periods can have different intrinsic brightnesses, complicating their use as standard candles."
p. 46
"Nevertheless, there’s no guarantee that tomorrow’s three-dimensional models won’t somehow change our understanding of stellar aging. Recent analyses have shaved one or two billion years from globular-cluster ages simply by modifying the way they accounted for convection in stellar atmosphere."
p. 46
"Taking stock of the universe’s age, size, and speed remains very much a work in progress."
