Im sure scientists must have such a thing since countless sciencefans positively assert as objective fact that there is no love
Love? Only a living being with a nervous system & brain is capable of emotions such as love. Rocks, air, the moon, stars, dark matter, galaxies etc. do not have such, thus they are incapable of love, hate or any other emotion.
There is no better love between 2 people than mutual respect for each other WT Young, 2002
Who gave anyone the authority to call me an authority on anything. WT Young, 1969
