Cosmology saying

"Man must rise above the Earth—to the top of the atmosphere and beyond—for only thus will he fully understand the world in which he lives." "Astronomy compels the soul to look upward, and leads us from this world to another."

Is cosmology the newest science?

"I think of cosmology as one of the oldest subjects of human interest but as one of the newest sciences," said Paul Steinhardt, a cosmologist at Princeton University who studies whether time has a beginning.
Cosmology, in a nutshell, studies the cosmos as one entity, rather than analyzing separately the stars, black holes and galaxies that fill it.
