Query: Backreaction in the future behavior of an expanding spacetime   We perform a rescaling analysis to analyze the future behavior of a class of
$T^2$-symmetric vacuum spacetimes. We show that on the universal cover, there
is $C^0$-convergence to a spatially homogeneous spacetime that does not satisfy
the vacuum Einstein equations.
