Utan tyngdkraften skulle vi alla sv\u00e4va iv\u00e4g ut i rymden. Det s\u00e4gs att Isaac Newton uppt\u00e4ckte tyngdkraften n\u00e4r ett \u00e4pple f\u00f6ll p\u00e5 hans huvud.<\/p>\n<\/div>\n<p>F\u00f6r att n\u00e5 rymden anv\u00e4nder vi en raketdriven b\u00e4rraket f\u00f6r att \u00f6vervinna jordens gravitation. Andra id\u00e9er har fr\u00e5n tid till annan lagts fram. \u00c5r 1865 f\u00f6reslog science fiction-f\u00f6rfattaren Jules Verne att man skulle anv\u00e4nda en kraftfull kanon f\u00f6r att skicka m\u00e4nniskor till m\u00e5nen. P\u00e5 senare tid har forskare studerat m\u00f6jligheten att anv\u00e4nda kraftfulla magneter f\u00f6r att skicka ett rymdskepp i omloppsbana.<\/p>\n<p>Raketer har funnits l\u00e4nge. De uppfanns i Kina f\u00f6r mer \u00e4n 800 \u00e5r sedan. De f\u00f6rsta raketerna var mycket enkla \u2013 ett kartongr\u00f6r fyllt med krut och f\u00e4st vid en styrpinne \u2013 ungef\u00e4r som de fyrverkerier vi anv\u00e4nder idag.<\/p>\n<p>\u00c5r 1232 anv\u00e4nde kineserna dessa \u2018eldpilar\u2019 f\u00f6r att besegra den invaderande mongoliska arm\u00e9n. Kunskapen om hur man tillverkar raketer spred sig snart till Mellan\u00f6stern och Europa, d\u00e4r de ocks\u00e5 anv\u00e4ndes som vapen.
