Hartle-Hawking initial state استات ِ آغازین ِ هارتل-هاؤکینگ estât-e âqâzin-e Hartle-Hawking
*Fr.: état initial de Hartle-Hawking *
A proposal regarding the initial state of the → *Universe*
prior to the → *Planck era*. This
→ *no boundary hypothesis* assumes an imaginary time in that epoch.
In other words, there was no real time before the → *Big Bang*,
and the Universe did not have a beginning. Moreover, this model treats the Universe like
a quantum particle, in an attempt to encompass → *quantum mechanics*
and → *general relativity*;
and attributes a → *wave function* to the Universe.
The wave function has a large value for our own Universe, but small, non-zero values
for an infinite number of other possible, parallel Universes. Hartle, J., Hawking, S., 1983, "Wave function of the Universe," Physical Review D 28;
→ *initial*; → *state*. |
