We define the Hartle-Hawking no-boundary wave function for causal set quantum gravity over the discrete analogs of spacelike hypersurfaces. Using Markov Chain Monte Carlo and numerical integration... the Hartle-Hawking no-boundary-state for that model explicitely. The dependence of that The dependence of that state on the 3-metric turns out to be the same as

## Hartle Hawking No-boundary Wave-function Pdf

Abstract Using the Hartle-Hawking no-boundary proposal for the wave function of the universe, we can study the wave function and probability of a single black hole created at the birth of the universe.

- In this paper we have described the Hartle-Hawking no boundary proposal concerning the Randall- Sundrum cosmological scenario, nonlocal braneworld action in the two-brane Randall-Sundrum model, Hartle-Hawking wave-function in the mini-superspace sector of physical superstring theory,
- The no-boundary wave function predicts that all his-tories that behave classically at late times undergo a period ofinflation at early times as shown here by the linear growth of theinstantaneous Hubble constant h^ a^;t=a^ in five representativeclassical histories for 3 and for 0 between 1.3 and 4.JAMES B.

- One proposal, due to Hartle and Hawking, is that "the initial boundary condition of the Universe is that it had no boundary." Popular books describe this proposal with varying degrees of accuracy. (See PBS's " Stephen Hawking's Universe " for a fairly good example.)
