Je toti\u017e pravdou, \u017ee ji nem\u016f\u017eeme p\u0159\u00edmo pozorovat. Vid\u00edme pouze jej\u00ed n\u00e1sledky, av\u0161ak ty jsou takov\u00e9, \u017ee o jej\u00ed existenci nen\u00ed pochyb. Alespo\u0148 tedy pokud pochop\u00edme, jak vlastn\u011b funguje.\u00a0\u00a0Z\u00e1kladn\u00edm pravidlem, kter\u00e9 mus\u00edme pochopit, je to, \u017ee ka\u017ed\u00fd p\u0159edm\u011bt, kter\u00fd m\u00e1 hmotnost, k\u00a0sob\u011b p\u0159itahuje dal\u0161\u00ed hmotn\u00e9 p\u0159edm\u011bty. Samoz\u0159ejm\u011b je zde p\u0159\u00edm\u00e1 \u00fam\u011brnost, kdy \u010d\u00edm vy\u0161\u0161\u00ed je hustota a hmotnost, t\u00edm v\u011bt\u0161\u00ed p\u0159ita\u017elivou s\u00edlu tento p\u0159edm\u011bt m\u00e1.\u00a0Samoz\u0159ejm\u011b, m\u016f\u017eeme nam\u00edtnout, \u017ee nap\u0159\u00edklad pokud vedle sebe d\u00e1me lehkou plastovou l\u00e1hev a velkou t\u011b\u017ekou kouli, p\u0159itahovat se nebudou. Av\u0161ak zde je pot\u0159eba si uv\u011bdomit dv\u011b skute\u010dnosti. Jednou z\u00a0nich je fakt, \u017ee gravita\u010dn\u00ed s\u00edla je ve skute\u010dnosti velmi slab\u00e1. Je tedy pot\u0159eba, aby rozd\u00edl ve hmotnosti byl skute\u010dn\u011b velk\u00fd, aby byl efekt skute\u010dn\u011b viditeln\u00fd.\u00a0\u00a0Ta druh\u00e1 souvis\u00ed s\u00a0tou prvn\u00ed. Jak na kouli, tak i na l\u00e1hev p\u016fsob\u00ed dal\u0161\u00ed p\u0159edm\u011bt, a to mnohem, mnohem v\u011bt\u0161\u00ed silou. T\u00edm je na\u0161e planeta jako celek. Je tedy jasn\u00e9, \u017ee koule l\u00e1hev nep\u0159it\u00e1hne, nebo\u0165 rozd\u00edl v\u00a0jejich hmot\u011b je p\u0159\u00edli\u0161 mal\u00fd, a nav\u00edc na n\u011b p\u016fsob\u00ed dal\u0161\u00ed, mnohem siln\u011bj\u0161\u00ed gravita\u010dn\u00ed s\u00edla.\u00a0Pokud tedy chceme skute\u010dn\u011b testovat \u00fa\u010dinky gravitace, pot\u0159ebujeme se dostat z\u00a0vlivu ostatn\u00edch p\u0159edm\u011bt\u016f, co\u017e rozhodn\u011b nen\u00ed jednoduch\u00e9.

To je na\u0161t\u011bst\u00ed mo\u017en\u00e9, a pr\u00e1v\u011b zde jsou prov\u00e1d\u011bny nejr\u016fzn\u011bj\u0161\u00ed pokusy.\u00a0Navzdory tomu, co si n\u011bkte\u0159\u00ed lid\u00e9 mysl\u00ed, tedy nen\u00ed pochyb o tom, \u017ee gravitace funguje. Pr\u00e1v\u011b ona n\u00e1s p\u0159itahuje k\u00a0na\u0161\u00ed planet\u011b, a to nejen n\u00e1s jako lidi, ale dokonce i molekuly vzduchu a atmosf\u00e9ru. A d\u00edky tomu m\u016f\u017ee na na\u0161\u00ed planet\u011b existovat \u017eivot.
