That's what we talk about today. • The paper has now been published here: • https://iopscience.iop.org/article/10... • An open-access version is here: • https://arxiv.org/pdf/2102.06824.pdf • You can find more information about the authors' work here: • https://appliedphysics.org • When I talk about energy conservation around 7 mins, I am NOT referring to the conservation of the stress-energy-tensor. This is conservation is always fulfilled if Einstein's field equations are fulfilled by way of the (contracted) Bianchi identities. I am talking about the conservation of the four-momentum (the integrated quantity) that is associated with the warp-drive bubble. In an asymptotically flat space-time, it should be conserved. If the bubble accelerates, it isn't.
