May I introduce: the universe. Born 13.75 billion years ago. Constantly growing. Nearly empty. Electrically neutral. Poor in antimatter. Populated by 100 billion galaxies, including 130 sextillion stars with approximately just as many planets.
Consisting of only 4 percent known forms of matter. The other 96 percent is made up of 23 percent dark matter and 73 percent dark energy. The home of black holes, giant stars, pulsars, quasars, galaxy clusters, and nebulas - and to many planets and their moons, as well as lifeforms such as humans.
Where did the universe come from? What were the conditions at its birth? What amazing processes have been taking place since then? When and how will it die? What science knows about these things has changed dramatically in recent years. Let yourself be taken away into a world that goes beyond everything imaginable ? the universe in which you live.
