    Unibertsoko objektu dentsenen sekretuak aztertzen ditugu: zulo beltzak, non argia ere harrapatuta geratzen den, neutroi izarrak beren sinesgaitzeko dentsitateekin, eta pulsarren erritmo kosmikoak.

    Izarren Heriotzatik Jaiotako Misterioak

    “

    Supernoben eztanda hauek ez dira soilik heriotza-momentuak; sorrera-momentuak ere badira. Gure gorputzeko karbono-atomoak eta odoleko burdina izarren barruetan sortu ziren duela milioika urte; Carl Sagan-ek esan zuen bezala, 'izar-hautsa gara.'

    Unibertsoaren Misterio Beltzenak

    0:00

    Kaixo, entzule! Imajinatzen duzu unibertsoan objektu bat dagoela hain indartsua non argiak ere ezin duen bertatik ihes egin? Gaur, izarren heriotzatik jaiotzen diren misterio kosmikoak aztertuko ditugu: zulo beltzak, neutroi izarrak eta pulsarrak. Harrigarria da, baina zulo beltz batek Eguzkiaren masa 4,3 milioi aldiz izan dezake, Esne Bidean dagoen Sagitario A* bezala. Eta hori ez da dena – pentsatu al duzu inoiz zer gertatzen den izarrak kolapsatzen direnean? Batzuetan, neutroi izar bihurtzen dira, non teila-kamioi bat betetzen duen materiala lurreko azukre-koxkor batean sartuko litzatekeen. Prestatu zaitez espazio-denboraren mugan dagoen bidaia zirraragarri baterako...
