==Landau–Lifshitz pseudotensor<!'Landau–Lifshitz pseudotensor' and 'LandauLifshitz pseudotensor' redirect here>==
The use of the '''Landau–Lifshitz pseudotensor'''<!boldface per WP:R#PLA>, (a combined ''matter'' plus ''gravitational stress–energy–momentum'' [[pseudotensor]] for combined matter (including photons and neutrinos) plus gravity,<ref name="LL">[[Lev Davidovich Landau]] and [[Evgeny Mikhailovich Lifshitz]], ''The Classical Theory of Fields'', (1951), Pergamon Press, {{ISBN7506242567}} chapter 11, section #96</ref> allows the energy–momentum conservation laws to be extended into [[general relativity]]. Subtraction of the matter [[stress–energy–momentum tensor]] from the combined pseudotensor results in the gravitational stress–energy–momentum pseudotensor.
