Roku 1964 rozdělil sovětský astronom Nikolaj Kardašov civilizace ve vesmíru na tři typy podle toho, kolik energie ovládnou – planetu, hvězdu, nebo celou galaxii. Lidstvo dnes podle Saganova vzorce stojí zhruba na hodnotě 0,73 a do typu I mu chybí asi pětisetnásobek dnešní spotřeby. Kdy bychom ho mohli dosáhnout, co je Dysonova sféra a proč jsme zatím žádnou cizí civilizaci nenašli?
👉 Napiš do komentářů: Za kolik let dosáhneme typu jedna?
