perhaps it is just a nonsense but can we express or could we express(adsbygoogle = window.adsbygoogle || []).push({});

[tex] g_{ab }(x) = \int exp(iux)a(+)f(+) + \int exp(-iux)a(-)f(-) [/tex]

the idea is, we express the metric g_ab in terms of the creation an anhinilation operators

we write also [tex] \pi _ab [/tex] (conjugate momenta) as a sum of creation of anhinilation operator

the qeustion is that if energy depends on curvature depending of the curvature and the operators a(+) and a(-) the metric can 'create' a flux of virtual particles

here f(+) and f(-) are functions that satisfy the following wave equation [tex] g_{ab} \nabla \nabla f(+,-) =0 [/tex]

here 'nabla' means the covariant derivative operator
