TY - JOUR T1 - Netušená vlastnost Schwarzschildovy metriky A1 - Křížek, Michal JA - Obzory matematiky, fyziky a informatiky Y1 - 2018 VL - 47 IS - 2 SP - 25 EP - 29 SN - 1335-4981 N2 - In this paper, we show that the difference between the classica lEuclidean geometry and the Schwarzschild geometry of a curved space corresponding to a tiny mass ball can be quite essential. Changes of the volume will be apparent on large galactic and cosmological scales. ER -
