Uvazhaemyi gospodin Mamaev!
Esli by, ka Vy predpolagaete, sverhnovye v osnovnom vzryvalis' dvazhdy so sravnitel'no korotkim promezhutkom mezhdu vzryvami (a v dlitel'nom promezhutke vremeni i bol'she raz), to:
a) Sverhnovuyu 1987A nablyudali by voochiyu (!) astronomy-lyubiteli yuzhnogo polushariya (napomnyu, chto yarkost' v maksimume byla +3m, to est' vidimaya nevooruzhennym glazom), ot kotoryh NASA, takim obrazom, nichego by ne smoglo skryt'.
b) v hronikah (ot nablyudenii kitaicami v 1006, 1054 godah i do sverhnovoi Keplera) byli by upominaniya o vtorom maksimume vspyshek novyh zvezd.
Ni togo, ni drugogo ne nablyudaetsya. Esli vy schitaete, chto 1987A vspyhnula seichas, to navernyaka v yuzhnom polusharii mozhno naiti teleskop-robot, upravlyaemyi iz interneta, i navesti ego na etu zvezdu. Dlya celi obnaruzheniya zvezdy yarkost'yu +3m (ili dazhe +9m) Vam hvatit dazhe 10-sm teleskopa.
Nadeyus', ya rasseyal Vashi somneniya.
S uvazheniem,
Dima
