Hello, I was wondering, since gravitational waves carry energy-momentum, would it be possible to find them in regions where the components of the metric tensor vanish? That is to say, empty space (non-quantum) is described by a vanishing energy-momentum tensor - but then, if gravitational waves propagate in such regions, how can there be no energy-momentum in the region?(adsbygoogle = window.adsbygoogle || []).push({});
