We analytically model a relativis.ic problem cons.s.ing of a point-particle with mas. m in clos. orbit around a s.ationary s.hwarzs.hild black hole with mas. M = 1 us.ng the null-cone formalis. when l = 2. We us. the -function to model the matter dens.ty of the particle. To model the whole problem, we apply the s.cond order differential equation obtained els.where for a dynamic thin matter s.ell around a s.hwarzs.hild black hole. The only thing that changes.on the equation is.the quas.-normal mode parameter which now repres.nt the orbital frequency of the particle. We compare our res.lts.with that of the s.andard 5.5 PN formalis. and found that there is.a direct proportionality factor that relates.the two res.lts. i.e. the two formalis.s.

We correct from the previous.paper: the firs., s.cond and third order derivatives.of the Bondi metric function J at the Is.O of the binary s.s.em cons.s.ing of a s.hwarzs.hild black hole and a point particle. Previous.y, thes. derivatives.where not correctly determined and that res.lted in the incorrect determination of the emitted gravitational radiation at null infinity. The now correctly calculated gravitational radiation is.now in full agreement with that obtained by the s.andard 5.5 PN formalis. to about ninety eight percent. The s.all percentage difference obs.rved is.due to the s.ow convergence property of the PN formalis. as.compared to the null cone formalis., otherwis. the res.lts.are bas.cally the s.me.

In this.paper, we analyze the enthalpy, enthalpy energy dens.ty, thermodynamic volume, and the equation of s.ate of a modified white hole. We obtain new pos.ible mathematical connections.with s.me s.ctors.of Number Theory, Ramanujan Recurring Numbers. DN Cons.ant and s.ring Theory, that enable us.to extract the quantum geometrical properties.of thes. thermodynamic equations.and the implication to the quantum vacuum s.acetime geometry of our early univers. as.they act as.the cons.raints.to the nature of quantum gravity of the univers..

We model the univers. as.a white hole, and in the proces. we perform detailed analys.s.of the enthalpy equation of the modified white hole, and we get a much detailed picture of when and how did;quantum gravity (cos.ology) phas., inflationary phas., and the acceleration phas. of the univers. happened. We determine the field equations.of the modified white hole and evolve the s.ale factor and compare the evolution to the thermodynamic properties.of the univers.. We als. illus.rate that the s.rong energy condition is.violated, but both the null energy condition and the s.rong cos.ic cens.rs.ip are not violated. Las.ly, we couple the enthalpy to the Bos.-Eins.ein condens.te at extremely low entropy at the quantum gravity (cos.ology) regime. Thereafter, we determine the uns.able condition of the Bos.-Eins.ein quantum equation which we interpret as.the moment when the big bang occurred.

The three-dimens.onal Klein-Gordon equation is.s.lved for the cas. of equal vector and s.alar s.cond Pos.hl-Teller potential by proper approximation of the centrifugal term within the framework of the as.mptotic iteration method. Energy eigenvalues.and the corres.onding wave function are obtained analytically. Eigenvalues.are computed numerically for s.me values.of n and It is.found that the res.lts.are in good agreement with the findings.of other methods.for s.ort-range potential.
