ʻO ke kukui hoʻomaha i loko o kahi hakahaka

Wahi a ka physicist ʻo James Franson o ke Kulanui o Maryland, nāna i aʻo i ka supernova SN 1987A, e emi ana ka māmā o ka māmā i loko o kahi hakahaka. Ua paʻi ʻia kāna mau palapala i loko o ka puke moʻolelo ʻepekema hanohano "Journal of Physics", no laila ua hilinaʻi lākou. Inā hoʻopaʻa ʻia lākou, ʻo ia ke ʻano o ka loli nui o ka ʻepekema, e mālama ana i ka wikiwiki o ka mālamalama i loko o kahi ʻūhā (299792,458 km / h) ma ke ʻano he mau mea nui.

Ua ʻike ʻo Franson he ʻokoʻa ka wikiwiki o ka neutrinos a me nā photons mai kahi supernova e hiki mai iā mākou. Hiki mai nā Neutrino i mau hola ma mua o nā photon. Wahi a ka physicist, ma muli paha kēia i ka ʻoiaʻiʻo i loko o kahi moena, hiki ke hoʻopili ʻia nā photon i nā electrons a me nā positrons, a laila hui hou i nā photons. Ke hoʻokaʻawale ʻia nā ʻāpana, hiki ke ala mai ka pilina umekaumaha ma waena o lākou, e kōkua ana i ka deceleration.

Ma muli o ka emi ʻana o ka māmā i ka lōʻihi o kāna huakaʻi, ʻoiai ke piʻi aʻe nei ka nui o nā stratification ʻāpana. Ma nā mamao i ana ʻia i nā miliona mau makahiki māmā, ʻo ka lohi o ka photon o ka mālamalama he mau pule.
