Description
General relativity tells us that an infinite number of houses can be built at fixed altitudes in the one meter (say) above the horizon, as measured in Euclidian geometry. Let this infinite number of houses exist. Let the street numbers of the houses increment with decreasing altitude. For someone crossing the horizon at the end of this street of houses, what is the street number of the last house passed?
