Skoree vsego avtory snimka ne pravy, utverzhdaya, chto Betel'geize staraya zvezda. Ya schitayu, chto vse kak raz naoborot - Betel'geize molodaya zvezda, obrazuyushayasya iz gazopylevoi
tumannosti kotoraya, postepenno uplotnyayas' sinteziruet tyazhelye himicheskie elementy i nepreryvno povyshaet svoyu temperaturu. Osmelyus' zayavit', chto vse zvezdy bez isklyucheniya imeyut
planetnye sistemy, tak kak zakony Vselennoi universal'ny dlya lyuboi zvezdy.
