1 APR ʻo kekahi manawa lōʻihi o ka noiʻi e pili ana i ka ʻimi ʻana a me ke aʻo ʻana i nā nalu ʻumekaumaha. A i kēia manawa, hoʻokahi mahina ma hope, ua hoʻolaha ʻia nā ʻike kūleʻa mua i loko o kēia pae o ka hana.
LIGO (Laser Interferometer Gravitational-Wave Observatory) a me Virgo hoʻohana ʻia e ʻike i nā nalu ʻumekaumaha. Hoʻohui ka mea mua i ʻelua complexes, aia ma United States ma Livingston (Louisiana) a me Hanford (Washington State). Ma ka huli, aia ka Virgo detector ma ka European Gravitational Observatory (EGO).
No laila, ua hōʻike ʻia ma ka hopena o ʻApelila ua hiki ke hoʻopaʻa inoa i ʻelua mau hōʻailona gravitational i ka manawa hoʻokahi. Ua hoʻopaʻa ʻia ka mea mua ma ʻApelila 25. ʻO kona kumu, e like me ka ʻike mua, he pōʻino kosmic - ka hui ʻana o ʻelua mau hōkū neutron. Hoʻohālikelike ka nui o ia mau mea me ka nui o ka Lā, akā ʻo ka radius he 10-20 mau kilomita wale nō. Aia ke kumu o ka hōʻailona ma kahi mamao o 500 miliona mau makahiki māmā mai mākou.
Ua hoʻopaʻa ʻia ka hanana ʻelua ma ka lā 26 ʻApelila. Manaʻo nā kānaka ʻepekema i kēia manawa ua hānau ʻia nā nalu gravity ma muli o ka hui ʻana o kahi hōkū neutron a me kahi lua ʻeleʻele ma kahi mamao o 1,2 biliona mau makahiki māmā mai ka Honua.
E hoʻomaopopo ua hoʻolaha ʻia ka ʻike mua ʻana o nā nalu ʻumekaumaha ma Pepeluali 11, 2016 - ʻo kā lākou kumu ka hui ʻana o nā lua ʻeleʻele ʻelua. A i ka makahiki 2017, ʻike mua nā kānaka ʻepekema i nā nalu gravity mai ka hui ʻana o ʻelua mau hōkū neutron.
