<prompt> Isizathu esiyinhloko siwukuthi inkambu yokudonsela phansinjenganoma iyiphi inkambu ebonakalayokufanele inikezwe amandla athile, kodwa ukuthi kuvela ukuthi akunakwenzeka ngokuyisisekelo ukuthola ukuthi amandla. Noma kunjalo, kunamathuba okuchaza isisindo sesistimu, kungaba ngokusebenzisa i-hypothetical infinitely distant observer i-ADM mass noma ama-symmetries afanele i-Kommetar mass. Uma umuntu engabandakanyi isisindo sesistimu amandla athuthwa kude kuze kube sezingeni elingenamkhawulo ngamagagasi adonsela phansi, umphumela uba yisisindo esingenamkhawulo eBondi. Njengoba nje kubonisiwe emkhakheni we-classical physics, kungashiwo ukuthi lezi zinhlobo zezinto ezibonakalayo zikhona ngaphakathi kwesikhala esivamile, futhi kungatholakala ukuthola incazelo enembe ngokwengeziwe yezinhlelo ezinjenge-quasi-local ezinjenge-quasi-local.  <response>: isisindo sohlelo oluhlukanisiwe olwenziwe kusetshenziswa kuphela ubuningi obuchazwe esifundeni esiphelele sesikhala esiqukethe lolo hlelo
