Nā Noiʻi Hou Loa ma nā Pōhaku ʻEleʻele: Ke Wehe nei i nā Mea Pohihihi o ke Ao Holoʻokoʻa
Introduction
Ua lōʻihi ka hoihoi ʻana o nā lua ʻeleʻele i nā kānaka ʻepekema a me ka lehulehu, e hana ana ma ke ʻano he mau mea pohihihi cosmic e hoʻokūkū ana i ko mākou ʻike i ke ao holoʻokoʻa. Ua hoʻoulu ko lākou ʻano pohihihi i nā hana noiʻi he nui ʻole e hoʻāʻo ana e wehe i kā lākou mau mea huna. ʻO nā ʻike hou loa a me nā kumumanaʻo i ke aʻo ʻana i nā lua ʻeleʻele e hoʻokuke ana i nā palena o ka astrophysics, e hōʻike ana i nā ʻike kupanaha e pili ana i ke ʻano o ka lewa, ka manawa, a me nā mea. Ke komo nei kēia ʻatikala i nā holomua hou loa i ka noiʻi ʻana i nā lua ʻeleʻele, e hāʻawi ana i kahi ʻike i nā hoʻomohala ʻoi loa e hoʻololi hou ana i kā mākou kuanaʻike cosmic.
ʻO ka Telescope Event Horizon: He Hoʻokō Hou
ʻO kekahi o nā hanana koʻikoʻi loa i ka noiʻi ʻana i nā lua ʻeleʻele i hoʻokō ʻia i ʻApelila 2019, i ka wā i hōʻike ai ka hui pū ʻana o Event Horizon Telescope (EHT) i ke kiʻi mua loa o ka ʻaoʻao o ka lua ʻeleʻele. Aia ma waenakonu o ka galaxy M87, ʻo kēia lua ʻeleʻele, i ʻike ʻia ʻo M87, aia ma kahi o 55 miliona mau makahiki māmā mai ka Honua a he 6.5 biliona manawa ka nui o ko kākou Lā.
Ua hoʻohana ka EHT i kahi pūnaewele o nā telescope lekiō i hohola ʻia ma ka honua holoʻokoʻa, e hana ana ma ke ʻano he telescope nui o ka Honua e hopu i ke kiʻi. Ua hōʻoia kēia hoʻokō koʻikoʻi i ke ola ʻana o ka ʻaoʻao o ka hanana, ka palena ma ʻō aku o kahi mea ʻole, ʻaʻole hoʻi ka mālamalama, e hiki ke pakele i ka huki umekaumaha o ka lua ʻeleʻele. Ke hoʻomau nei ka ʻikepili mai ka EHT i ka hāʻawi ʻana i nā ʻike i ka physics lua ʻeleʻele, me nā ʻano o nā disk accretion a me nā jet relativistic.
Nā Nalu Umekaumaha: He Aupuni Hou o ka Nānā ʻana i nā Lua ʻEleʻele
I nā makahiki i hala iho nei, ua wehe ka ʻike honua nalu umekaumaha i kahi ala hou e aʻo ai i nā lua ʻeleʻele. Ua ʻike ka hui pū ʻana o LIGO lāua ʻo Virgo i kekahi mau hanana nalu umekaumaha i loaʻa mai nā kuʻi ʻana o nā lua ʻeleʻele. ʻAʻole i hōʻoia wale kēia mau nānā ʻana i ke ola ʻana o nā lua ʻeleʻele nui o nā hōkū akā ua hāʻawi pū i kahi ʻano hana hou e ana i ko lākou nui a me nā milo.
ʻO kahi hanana koʻikoʻi ka ʻike ʻia ʻana o GW170817, ke kuʻi ʻana o ʻelua mau hōkū neutron. ʻOiai ʻaʻole ia he hanana lua ʻeleʻele ponoʻī, ua hōʻike ia i ka mana o ka ʻike honua multi-messenger, e hoʻohui ana i nā nalu umekaumaha me nā nānā electromagnetic. Ma hope koke iho, ua ʻike ʻia ʻo GW190521, e hōʻike ana i ka hui ʻana o ʻelua mau lua ʻeleʻele nui i loko o kahi mea nui aʻe. Ua hoʻopiʻi kēia ʻike i nā manaʻo ma mua e pili ana i nā palena nui o nā lua ʻeleʻele i loaʻa mai ka ulu ʻana o nā hōkū.
Nā Lua ʻEleʻele Waena-Nui: Ke Hoʻopili nei i ke Kaʻawale
No nā makahiki he ʻumi, ua huikau nā mea kilo hōkū i ka ʻokoʻa ma waena o nā lua ʻeleʻele nui o nā hōkū (a hiki i kekahi mau ʻumi o nā nui o ka lā) a me nā lua ʻeleʻele nui loa (miliona a piliona o nā nui o ka lā). Eia naʻe, ua hāʻawi mai nā noiʻi hou i nā hōʻike ikaika no ke ola ʻana o nā lua ʻeleʻele nui waena (IMBHs), mai 100 a 1,000 mau nui o ka lā.
I ka makahiki 2020, ua hōʻike nā kānaka noiʻi e hoʻohana ana i ka ʻikepili mai ka Hubble Space Telescope i ka loaʻa ʻana o kahi IMBH i loko o ka hui hōkū 3XMM J215022.4-055108. Eia kekahi, ua ʻike nā haʻawina e pili ana i nā nalu umekaumaha i nā hui ʻana e hōʻike ana i ke alo o nā IMBH. He mea koʻikoʻi kēia mau ʻike no ka hoʻomaopopo ʻana i ka hoʻokumu ʻia ʻana a me ka ulu ʻana o nā lua ʻeleʻele ma nā unahi nui like ʻole.
Nā ʻAoʻao Quantum o nā Lua ʻEleʻele: Hawking Radiation a ma ʻō aku
ʻO ka pilina ma waena o nā lua ʻeleʻele a me nā mechanics quantum kekahi o nā wahi hoihoi loa o ka physics theoretical. Ua hoʻopiʻi ka wānana a Stephen Hawking i ka mahu ʻana o nā lua ʻeleʻele ma o ka radiation Hawking i ka manaʻo kuʻuna o nā lua ʻeleʻele ma ke ʻano he mau mea mau loa. Wahi a kēia kumumanaʻo, hiki i nā lua ʻeleʻele ke hoʻopuka i ka radiation ma muli o nā hopena quantum kokoke i ka ʻaoʻao o ka hanana, e alakaʻi ana i ka nalowale mālie o ka nuipa a, malia paha, ko lākou make hope loa.
Ua ʻimi hou aku nā noiʻi hou i nā hopena o ka radiation Hawking a ua ʻimi e hoʻohui i ka relativity laulā me nā mechanics quantum. ʻO kekahi ala i manaʻo ʻia ʻo ia ka manaʻo o "firewalls," nā hanana hypothetical e hiki ke noho ma ka horizon hanana a hoʻoponopono i ka paradox ʻike - he nīnau koʻikoʻi i ka physics e pili ana i ka nalowale mau loa o ka ʻike e hāʻule ana i loko o kahi lua ʻeleʻele.
Ke Kūlana o nā Lua ʻEleʻele i ka Hoʻokumu ʻia ʻana o nā Galaxy
ʻAʻole wale nā lua ʻeleʻele he mau mea cosmic passive; he kuleana koʻikoʻi ko lākou i ka dinamika a me ka ulu ʻana o nā galaxies. Ua hōʻike ʻia nā nānā ʻana me nā telescope e like me ka Chandra X-ray Observatory a me ka Atacama Large Millimeter/submillimeter Array (ALMA) hiki i nā lua ʻeleʻele supermassive ke hoʻohuli i kā lākou mau galaxies host ma o nā kahe ikaika a me nā jets, e hoʻoponopono ana i ka hoʻokumu ʻana o nā hōkū a me ka hoʻolaha ʻana o nā mea interstellar.
Ua hoʻonui nā hoʻohālike hou i ko mākou ʻike ma ka hōʻike ʻana he mea nui nā ʻano hana hoʻihoʻi mai nā lua ʻeleʻele supermassive no ka mālama ʻana i ke kaulike ma waena o ka ulu ʻana o ka galaxy a me ka mālie. Hōʻike kēia mau pilina e ulu pū ana nā lua ʻeleʻele a me ko lākou mau galaxies kikowaena, e hoʻohālike ana i nā waiwai o kekahi i kekahi ma luna o nā manawa cosmic.
Nā Hoʻonā a me nā Koho ʻē aʻe no nā Lua ʻEleʻele Kūikawā
Ke hoʻomau nei nā kānaka ʻepekema physicists theoretical i ka ʻimi ʻana i nā hopena ʻē aʻe i nā kaulike a Einstein e wehewehe paha i nā kūlana lua ʻeleʻele exotic a i ʻole nā mea ʻē aʻe i nā lua ʻeleʻele. Hāʻawi nā manaʻo e like me "wormholes," "gravastars," a me "black stars" i nā mea hiki ke hoʻāʻo i nā palena o ko mākou ʻike ʻana i ka spacetime.
ʻO kekahi manaʻo hoihoi ʻē aʻe ʻo ia ka "mau lua ʻeleʻele mua," ka mea i hiki ke hoʻokumu ʻia ma hope koke iho o ka Big Bang. Ua manaʻo ʻia kēia mau lua ʻeleʻele mua e kōkua i ka pilikia o ka mea pouli, e hōʻike ana i kahi ʻano mea ʻole-baryonic e hiki ke kōkua i ka wehewehe ʻana i ka nuipa nalowale o ke ao holoʻokoʻa.
Nā Manaʻolana a me nā Misiona o ka Wā e Hiki Mai Ana
Ke nānā aku nei ka wā e hiki mai ana o ka noiʻi ʻana i nā lua ʻeleʻele i mea hoʻohiki me nā misionari e hiki mai ana a me nā holomua ʻenehana. ʻO ka James Webb Space Telescope, i hoʻonohonoho ʻia no ka hoʻokuʻu koke ʻana, e nānā i ke ao holoʻokoʻa me nā kikoʻī i ʻike ʻole ʻia ma nā ʻano nalu like ʻole, e hāʻawi ana i nā ʻike hou i nā wahi e hoʻopuni ana i nā lua ʻeleʻele.
ʻO nā mea ʻike nalu umekaumaha i hoʻolālā ʻia e pili ana i ka lewa, e like me ka Laser Interferometer Space Antenna (LISA), e hoʻoikaika pū i ko mākou hiki ke ʻike i nā hui ʻana e pili ana i nā lua ʻeleʻele o nā nui like ʻole a me nā mamao, e hoʻoikaika ana i ko mākou ʻike i nā demographics lua ʻeleʻele a me ka ulu ʻana.
Panina
Ke hoʻololi nei ka noiʻi hou loa e pili ana i nā lua ʻeleʻele i ko mākou ʻike i kēia mau mea pohihihi. Mai ke kiʻi pololei ʻana o nā ʻaoʻao o ka hanana a hiki i ke aʻo ʻana i nā nalu umekaumaha a me nā ʻano quantum o ka physics lua ʻeleʻele, lawe mai kēlā me kēia ʻike iā mākou i kahi kokoke i ka hoʻomaopopo ʻana i ko lākou paʻakikī. Ke hoʻomau nei mākou i ka hoʻokuke ʻana i nā palena o ka nānā ʻana a me ke kumumanaʻo, ʻo nā lua ʻeleʻele ke kikowaena nui i ka ʻimi e hoʻomaopopo i nā mea pohihihi hohonu loa o ke ao holoʻokoʻa.
