- Yes, if it was true. But matter with a negative mass would react just
- the same as matter with a negative electrical charge. 2 negative
- {charged or mass} particles attract each other, 1 negative and one positive
- {charged or mass} particle repulse each other. And negative electricity
- doesn't give you a perpetual motion :-(
