Query: Are Most Particles Gravitons?   The number of baryons in the observable universe is of the order of
$10^{80}$, as is the number of electrons. The number of photons is about nine
orders of magnitude greater, $10^{89}$, as is the estimated number of
neutrinos. However, the number of gravitons could be more than twenty orders of
magnitude larger yet, of the order of $10^{113} r$, where $r$ is the
tensor-to-scalar ratio for quantum fluctuations produced by inflation, which
could be as high as $0.1$.
