Brez gravitacije bi vsi odplavali v vesolje. Pravijo, da je Isaac Newton odkril gravitacijo, ko mu je jabolko padlo na glavo.<\/p>\n<\/div>\n<p>Da bi dosegli vesolje, uporabljamo raketni nosilec, s katerim premagamo zemeljsko gravitacijo. Od \u010dasa do \u010dasa so bile predlagane tudi druge ideje. Leta 1865 je pisatelj znanstvene fantastike Jules Verne predlagal, da bi za po\u0161iljanje ljudi na Luno uporabili mo\u010dno topni\u0161ko oro\u017eje. V zadnjem \u010dasu znanstveniki preu\u010dujejo mo\u017enost uporabe mo\u010dnih magnetov za izstrelitev vesoljskega plovila v orbito.<\/p>\n<p>Rakete obstajajo \u017ee dolgo \u010dasa. Izumili so jih na Kitajskem pred ve\u010d kot 800 leti. Prve rakete so bile zelo preproste \u2013 kartonska cev, napolnjena s smodnikom in pritrjena na vodilno palico \u2013, podobne pirotehni\u010dnim izdelkom, ki jih uporabljamo danes.<\/p>\n<p>Leta 1232 so Kitajci s temi \u2018ognjenimi pu\u0161\u010dicami\u2019 premagali mongolsko invazijsko vojsko. Znanje o izdelavi raket se je kmalu raz\u0161irilo na Bli\u017enji vzhod in v Evropo, kjer so jih prav tako uporabljali kot oro\u017eje.
