Poyasnenie:
Vy vidite velikolepnyi spiral'nyi uzor krutyasheisya v vodovorote
galaktiki M100. Rasstoyanie do etoi galaktiki vyzyvaet
polnyi perepoloh sredi astronomov. Mnogie dumali, chto nedavnie izmereniya rasstoyaniya
do etoi galaktiki kosmicheskim teleskopom im. Habbla dadut
naibolee pravil'nyi temp rasshireniya Vselennoi. Drugie schitali, chto eti
izmereniya obmanchivy. Temp rasshireniya Vselennoi vychislyaetsya po velichine "postoyannoi Habbla". Pri delenii skorosti udaleniya galaktiki na etu postoyannuyu
poluchaetsya istinnoe rasstoyanie do nee. Vse eshe prodolzhayutsya nauchnye debaty, kasayushiesya znacheniya postoyannoi
Habbla,
kotorye nachalis' s momenta ee pervogo opredeleniya Edvinom Habblom v 1929 godu. V aprele 1996 goda sostoitsya konferenciya "Masshtaby Vselennoi", na kotoroi budet goryacho obsuzhdat'sya nastoyashee znachenie
