Quotes

  • “The n-point correlation functions have proved useful not only as descriptive statistics but also as dynamic variables in the Newtonian theory of the evolution of clustering. ... The functions are generalized to mass correlation functions in position and momentum, and the BBGKY hierarchy of equations for their evolution is derived. This yields a new way to analyze the evolution of mass clustering in an expanding universe.”
  • “A solid stores energy in the vibrations of the atoms about their equilibrium positions. In the simplest approximation, which Einstein considered, each atom vibrates with the same frequency, ν, in each of three dimensions, so a solid containing N atoms can be thought of as 3N one-dimensional simple harmonic oscillators.”
  • “Another somewhat confusing usage is the name "the big bang" for the standard model. It is not appropriate, because it connotes a spatially isolated event, an explosion, that marked the start of everything. ... But the name has a very evident appeal and I expect that people will continue to use it.”
  • “I have been working in cosmology for 55 years ... I'm the last man standing, so to speak, from those early days.”
  • “I don't think there is a final theory of anything. It's theories all the way down.”
  • “Don't pay too much attention to that Nobel Prize. They have to be capricious — they have to be. And that means that people fully deserving the award don't get it.”

Encyclopedic overview

Phillip James Edwin Peebles CC OM FRS (born April 25, 1935) is a Canadian-American astrophysicist, astronomer, and theoretical cosmologist who was Albert Einstein Professor in Science, emeritus, at Princeton University. He is widely regarded as one of the world's leading theoretical cosmologists in the period since 1970, with major theoretical contributions to primordial nucleosynthesis, dark matter, the cosmic microwave background, and structure formation.

Peebles was awarded half of the Nobel Prize in Physics in 2019 for his theoretical discoveries in physical cosmology. He shared the prize with Michel Mayor and Didier Queloz for their discovery of an exoplanet orbiting a sun-like star. While much of his work relates to the development of the universe from its first few seconds, he is more skeptical about what we can know about the very beginning, and stated, "It's very unfortunate that one thinks of the beginning whereas in fact, we have no good theory of such a thing as the beginning."
