WebThat is perfectly okay because they are in the same equivalency class. So, it isn't really that they have a different sign, it is just a different representative for that equivalency class (in the rationals, it is similar to 1 2 = 2 4; same number, just different representatives for that equivalency class). Share Cite Follow WebConservation of energy can not have a negative value as it is totally violating the law of conservation of energy. Negative energy has no particular physical proof hence it can be said that if negative energy exists then all energies within the universe will be balanced by each other causing the total energy to vanish.
