[quote]We don't know that to always be true so we mustn't make that assumption.[/quote] Unless you give me any example that larger mass DOESN'T mean a larger gravitational pull, then don't make such a bold assertion. Every large celestial body in the observable universe exerts this idea. The larger the planet the larger the gravitational pull. Black holes which have an enormous amount of mass and density even effects the gravitational pull against light, so tell me again how we are wrong again?
