Gravitation is not responsible for people falling in love. - Einstein
Consider g' = 2g
F' = mg' = 2mg
W' = F*d = 2mgd
E' = W* t = 2mgdt
Therefore : E' : E = 2
Therefore if two lovers have to cross a tennis court to embrace then they have to use twice the energy, which means that they have half the energy to whisper sweet nothings ....
Conclusion - Einstein was wrong .... Gravity and love are intertwined (not including obesity problems)
