James Hartle
From Wikipedia, the free encyclopedia
James B. Hartle is an American physicist and professor of physics at the University of California, Santa Barbara (UCSB) since 1966. . He is known for his work in general relativity, astrophysics, and interpretation of quantum mechanics. Together with Stephen Hawking, he proposed the Hartle-Hawking wavefunction of the Universe - a specific solution to the Wheeler-deWitt equation meant to explain the initial conditions of the Big Bang cosmology.
In collaboration with Murray Gell-Mann and others, Hartle helped formulate the modern Copenhagen interpretation based on consistent histories. With Dieter Brill he discovered the Brill-Hartle geon, an approximate solution realizing Wheeler's suggestion of a hypothetical phenomenon in which a gravitational wave packet is confined to a compact region of spacetime, by the gravitational attraction of its own field energy. He is the author of a recent textbook on general relativity.
