There are at least 3 ways that the age of the Universe can be estimated. ... The age of the oldest star clusters. The age of the oldest white dwarf stars. ... When a rock solidifies, the chemical elements often get separated into different crystalline grains in the rock. ... But if the elements are made continuously at a constant rate, then the mean age of stuff in the Solar System is (t o + t SS )/2 = 8-11 Gyr which we can solve for the age of the Universe giving t o = 11.5-17.5 Gyr . ... Age | ...

Земля . Обилие жидкой воды на поверхности и кислорода в атмосфере - вот, пожалуй, основные отличия Земли от всех известных на сегодняшний день небесных тел. Если земная атмосфера представляется из космоса тонкой и прозрачной, и если бы не облака, она выглядела бы совсем жалко, то занимающие около 70% поверхности океаны выглядят впечатляюще. Средняя глубина этой полноправной оболочки - гидросферы - примерно 4 км, и она представляет собой не просто заполненные водой впадины. ...
