I whakamahia e tētahi rōpū kairangahau tētahi maramara rorohiko kotahi hei whakawhiti i te 1.84 petabytes (PB) o ngā raraunga ia hekona, tata ki te rua ngā wā o te nui o te haere o te Ipurangi katoa, ā, he rite tonu ki te tango i te 230 miriona whakaahua ia hekona.
Ko te putanga hou, e whakatakoto ana i tētahi rekoata hou mō te whakamahi i tētahi maramara rorohiko kotahi hei tuku raraunga mā runga i tētahi taura muka whatu, e oati ana ka hua ake he maramara pai ake te mahi ka taea te whakaiti i ngā utu pūngao me te whakanui ake i te whānui o te raraunga.
Kua tutuki i tētahi rōpū kaipūtaiao o te ao whānui tētahi whanaketanga nui i roto i te tuku raraunga muka whatu, mā te whakamahi i tētahi maramara rorohiko kotahi hei tuku i te 1.84 petabytes (PB) o ngā raraunga ia hekona—tata ki te rua o ngā rerenga katoa o te ipurangi, ā, he rite ki te 100,000 ngā tangohanga o te 230 miriona whakaahua ia hekona. Nā tēnei whanaketanga kua whakatūria he rekoata hou mō tētahi maramara kotahi e tuku raraunga ana mā tētahi taura whatu, ā, e matapaetia ana ka hua ake he maramara mahi pai ake me te whakapai ake i te mahi ipurangi.
I roto i te putanga hou o te hautaka Nature Photonics, e ai ki a Asbjorn Arvada Jorgensen o te Whare Wānanga Hangarau o Denmark me āna hoa mahi mai i Denmark, Sweden me Japan i whakamahia e rātou he maramara photonic (ngā wāhanga whatu kua whakauruhia ki roto i te maramara rorohiko) e wehewehe ana i te awa raraunga ki ngā mano o ngā hongere motuhake me te tuku i aua raraunga i te wā kotahi i runga i te whānuitanga o te 7.9 km.
I whakamahia e te tīma rangahau he rēseri hei wehewehe i te awa raraunga kia 37 ngā wāhanga, ia wāhanga ka tukuna mā roto i tētahi matua motuhake o te taura muka whatu, kātahi ka wehea ngā raraunga o ia hongere kia 223 ngā poraka raraunga, ka taea te tuku mā roto i te taura muka whatu i ngā tae rerekē me te kore e pokanoa tetahi ki tetahi.
"Ko te toharite o te haere o te ipurangi puta noa i te ao he tata ki te 1 petabyte ia hekona. E rua ngā wā e kawehia ana e mātou," te kī a Jorgensen. "He nui whakaharahara tēnei o ngā raraunga e tukuna ana e mātou mā roto i te iti iho i te mirimita tapawha [taura muka whatu]. E whakaatu ana tēnei ka taea e tātou te neke atu i tua atu i ngā hononga ipurangi o nāianei.”
E tohu ana a Jorgensen ko te hiranga o tēnei whakatutukitanga kāore i kitea i mua ko te whakaitiiti. I mua, kua eke ngā kaipūtaiao ki te tere whakawhiti raraunga o te 10.66 petabytes ia hekona mā te whakamahi i ngā taputapu nunui, engari i whakatūria e tēnei rangahau he rekoata hou mō te whakamahi i tētahi maramara rorohiko kotahi hei tuku raraunga mā runga i tētahi taura muka whatu, me te oati he maramara kotahi, māmā ka taea te tuku raraunga nui atu i ngā maramara o nāianei, ā, ka whakaitihia ngā utu pūngao me te whakanui ake i te whānui o te raraunga.
E whakapono ana hoki a Jorgensen ka taea e rātou te whakapai ake i te whirihoranga o nāianei. Ahakoa me whakamahi te maramara i tētahi taiaho tuku tonu me ngā taputapu motuhake hei whakawaehere raraunga i roto i ia rerenga putanga, ka taea te whakauru i ēnei ki roto i te maramara, kia rite te iti o te taputapu katoa ki tētahi pouaka mati.
E whakapae ana hoki te tīma rangahau mēnā ka whakarerekētia te rahi o te pūnaha kia rite ki tētahi tūmau iti, ko te nui o ngā raraunga ka taea te whakawhiti ka rite ki te nui o ngā taputapu 8,251 rite te rahi ki te pouaka mati i ēnei rā.
