He aha ka ka gravitational ikaika, e like me ka mea he pōpilikia a me keia waiwai ua hoʻohana 'ia ma kahi

E like me kekahi o nā pono kīvila kanaka mea ma ke kālaikūlohea, ka gravitational ikaika i mua i olelo ia i loko o ka 18th kenekulia. I ka Ia manawa i lawe mākou i nā ho'āʻo mua e ana ai i kona kumukuai, akā, ma muli o ia i ka hemahema o ka mea kani, a me ka nele o ka ike ma keia kula, e hana ka mea hiki wale nō i loko o ka hapalua like-19th kenekulia. Hope i kēia hopena Ua Hoomau pinepine like (no ka mea hope manawa i hanaia i ka 2013 kēia). Naʻe, ka mea e e hoʻomaopopo i ka luna likeʻole ma waena o ka mua (G = 6,67428 (67) · 10 ^-11 mau ^-2 · m³ · kg ^-1 a H · m² · ^-2 kg) a me ka hope (G = 6,67384 ( 80) · 10 ^-11 mau ^-2 · m³ · kg ^-1 a H · m² · kg ^-2) nā loina hakuʻole.

Ana keia ololi no ka mea hiki mau hana, e e hoomaopopo ia e like me ka ikaika i loko o hua'ōlelo o global paʻa (ināʻaʻole e e piko ma kula haʻahaʻaa huna ke kālaikūlohea a me nā uuku ike 'epekema). Kēia 'o ia hoʻi i ka gravitational a eia i o ka Honua, me ka Moon a Mars, e ole oko mai kekahi i kekahi.

Kēia waiwai He He kumu o ia a eia i loko o panina mechanics. No laila, i ka gravitational ikaika ua komo i loko o ka likeʻole ma o ka helu. I ka nui, me ka 'ike e pili ana i oi a emi ka kiko'ī waiwai o keia aiao, ka noiʻi hiki ole ho omaulia ia he nui ololi i loko o ka makahiki hana, ka hoʻonui o ka noa haule (a e lilo lākou no kēlā me kēia Honua' ole 'ē aʻe lani kino).

Akā, Newton, Kupanaha ma ke kānāwai o ka umekaumaha i loko o kekahi mau alanui, iʻikeʻia ka gravitational a eia wale ma ka kumumanaʻo. Oia hoi, ka mea, ua hiki ke formulate i kekahi o ka mea nui physical postulates, me ka ike e pili ana i ka uku ana i ka mea, ua, ma ka mea, ua nānā 'ana.

Haʻalele nā pono kīvila kanaka ia a eia i, e pili ana i ka mea i ka gravitational a eia i, ke kālaikūlohea hiki wale aku nei au i kekahi mau pololei mahele. Kona waiwai ua loaa hou kekahi manawa, a me kēlā me kēia manawa ia mea okoa mai ka mua kekahi. Ka hapanui oʻepekema manaʻo i kēia mea ua i pili i ka mea hoʻololi, akā, me ka hou AICIeOEOI kumu. Mua, (ua lawe no i ka ho omaulia ana o keia mau mai likeʻole ho okolohua) keia huahelu, a me ka lua, e neʻe i na mea maalea, i ke kiʻekiʻe o maoli, i nā ikepili i hoakaka ia, a ua loaa ka mea hou hopena.

Ua haawiia i ka mea i ka gravitational a eia i mea he nui ana 10 i -11 degere (i ka panina mechanics ultrasmall cia), ia mea e kahaha ko oukou naau a eia i ano hoohanohano a kaʻi lau waiwai. Ka oi ia mea malalo iho o ke? Iaea hōʻailona e hoʻomaka ana me ka 14 kekimala wahi.

Eia naʻe, he mea i loko o ke kālaikūlohea ke kēia nalu kekahi kumumanaʻo, i kau aku Fred Hoyle a. Narlikar John ma ka 70-ies o ka hope kenekulia. E like me kā lākou nā mea mahuʻi, ka gravitational ikaika emi me ka manawa, i loli ai na mea he nui 'ē nā hoailona e i manaoia o ia a eia. Penei, ka American astronomer van Flandern i koho ma ka kŰia o ka hōʻemi iki hoʻonui o ka Moon a me nā ano lani kahi. Alakaʻi ma keia kumumanaʻo, ka mea e e ea ae ia kekahi global hewa i loko o ka mua hoʻomaulia ole i hana ai, a me ka likeʻole i loko o nā hualoaʻa mea ku pono i ka loli a eia i loko o ka waiwai wale. Kēia ia kumumanaʻo mai nei e pili ana i ka impermanence o kekahi'ē aʻe aiaiiuo e like me ka mämä holo o ka malamalama ma ka holo.
