Cosmological Conundrums: A Conversation with Justin Khoury

Front Cover
Open Agenda Publishing, Oct 1, 2020 - Science - 50 pages

This book is based on an in-depth filmed conversation between Howard Burton and Justin Khoury, Professor of Physics at the University of Pennsylvania. This thoughtful, extensive conversation gives a window into the world of what a practicing, theoretical physicist cosmologist is doing all day long and examines a wide range of fascinating topics that his research covers such as the early universe, the Big Bang, dark matter, dark energy, Cosmic Microwave Background, the MOND (Modified Newtonian Dynamics) theory, and more.

This carefully-edited book includes an introduction, Into The Light, and questions for discussion at the end of each chapter:

I. Becoming A Physicist - The power of passion

II. The Victim of Its Success? - Swinging scientific pendulums

III. Periodically Fiery - Calculating colliding branes

IV. The CMB - Almost completely homogeneous

V. The Process of Discovery - Typically messier than you think

VI. Learning from History - Missing mass or missing theory?

VII. MOND vs. Dark Matter, Part I - Looking at galaxies

VIII. MOND vs. Dark Matter, Part II - Dark matter roars back

IX. Why Not Both? - The liquid helium analogy

X. Dark Energy - Vacuum energy and the cosmological constant problem

XI. Personal vs. Professional - The scientist as childlike iconoclast

XII. Revolutionary Rumblings - Cosmology’s Golden Age
