no, you see, True Love exists, but is unattainable by humans.
you Can't, and Don't, Science Love because, its more than one feeling, if the person you lvoe is happy, its easier to be happy, if there sad or upset, well, its likely that you are, you dont science it, because humans cannot fathom it. its as easy to understand and build an immunity too as hate. hate is more than one feeling too.
tell me, whats the science for hatred?
there probably isnt one, because humanity doesnt want to know about things that are uncomfortable. and if there is, well, then someone had a brain and decided that if your going to attempt to science the unsciencable, then you might as well do teh same for its polar opposite.
