Cosmologist Quotes (5 quotes)
If the universe is measurably curved today, cosmologists must accept the miraculous fact that this is so for the first time in the 1010-year history of the universe; if it had been measurably non-flat at much earlier times, it would be much more obviously curved today than it is. This line of reasoning suggests that the observable universe is essentially exactly flat: that it contains precisely the critical density of mass.
(1986). As quoted in Isaac Asimov's Book of Science and Nature Quotations.
Much later, when I discussed the problem with Einstein, he remarked that the introduction of the cosmological term was the biggest blunder he ever made in his life. But this “blunder,” rejected by Einstein, is still sometimes used by cosmologists even today, and the cosmological constant denoted by the Greek letter Λ rears its ugly head again and again and again.
My World Line (1970). Cited in Edward Robert Harrison, Cosmology: the Science of the Universe (2000), 379, which adds: “The Λ force is referred to by various names, such as the cosmological constant, cosmological term, cosmical constant or cosmical term.”
There’s a joke among cosmologists that romantics are made of stardust, but cynics are made of the nuclear waste of worn-out stars.
As co-author with Nancy Ellen Abrams, in The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos (2006), 279. With less clarity (with no reference to the worn-out stars), this was expressed earlier by Simon Singh, in Big Bang: The Most Important Scientific Discovery of All Time and Why You Need To Know About It (2004), 389, as: “Romantics might like to think of themselves as being composed of Stardust. Cynics might prefer to think of themselves as nuclear waste.”
To be a cosmologist, you have to know particle physics.
In David Michael Harland, The Big Bang (), viii
To cosmologists that [the universe is expanding] is the most amazing scientific discovery ever made. … It’s an audacious quest that is unparalleled in human inquiry. … We have entered what once was the ethereal realm only of speculative philosophers.
As quoted in John Noble Wilford, 'Sizing up the Cosmos: An Astronomers Quest', New York Times (12 Mar 1991), C10.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
