Query: UV cancelations in gravity loop integrands   In this work we explore the properties of four-dimensional gravity integrands
at large loop momenta. This analysis can not be done directly for the full
off-shell integrand but only becomes well-defined on cuts that allow us to
unambiguously specify labels for the loop variables. The ultraviolet region of
scattering amplitudes originates from poles at infinity of the loop integrands
and we show that in gravity these integcrands conceal a number of surprising
features. In particular, certain poles at infinity are absent which requires a
conspiracy between individual Feynman integrals contributing to the amplitude.
We suspect that this non-trivial behavior is a consequence of yet-to-be found
symmetry or hidden property of gravity amplitudes. We discuss mainly amplitudes
in $\mathcal{N}=8$ supergravity but most of the statements are valid for pure
gravity as well.
