Ma ka lā 1 o ʻApelila, hoʻomaka ka manawa lōʻihi o ka nānā ʻana, e kuhikuhi ana i ka ʻimi ʻana a me ke aʻo ʻana i nā nalu umekaumaha - nā hoʻololi i ke kula umekaumaha e hoʻolaha e like me nā nalu.
E komo nā loea mai ka LIGO a me Virgo observatories i ka hana hou o ka hana. E hoʻomanaʻo kākou ʻo LIGO (Laser Interferometer Gravitational-Wave Observatory) kahi mākaʻikaʻi ʻana i ka nalu interferometer laser. Aia ia i ʻelua mau poloka, aia ma ʻAmelika Hui Pū ʻIa ma Livingston (Louisiana) a me Hanford (Washington State) - ma kahi mamao o 3 tausani mau kilomita mai kēlā me kēia. No ka mea ua like ka wikiwiki o ka hoʻolaha ʻana o nā nalu gravitational me ka māmā o ka māmā, ua hāʻawi kēia mamao i kahi ʻokoʻa o 10 milliseconds, e hiki ai iā mākou ke hoʻoholo i ke kuhikuhi o ke kumu o ka hōʻailona i hoʻopaʻa ʻia.
No Virgo, aia kēia mea ʻike nalu umekaumaha Farani-Italia ma ka European Gravitational Observatory (EGO). ʻO kāna mea nui ka Michelson laser interferometer.
Hoʻokahi makahiki holoʻokoʻa ka pae o ka nānā ʻana. Ua hōʻike ʻia ʻo ka hoʻohui ʻana i nā mana o LIGO a me Virgo e hana i ka mea hana koʻikoʻi loa a hiki i kēia lā no ka ʻike ʻana i nā nalu gravity. Manaʻo ʻia e hiki i nā loea ke ʻike i nā hōʻailona o kahi ʻano hou mai nā kumu like ʻole o ka Universe.
Hoʻohui mākou ua hoʻolaha ʻia ka ʻike mua ʻana o nā nalu gravity ma Pepeluali 11, 2016 - ʻo kā lākou kumu ka hui ʻana o ʻelua mau lua ʻeleʻele.
