The Universe is 13.7 billion years old, +/- 1%. The first
stars appeared at about 200 million years after the Big Bang. It is
made up of 4% atoms, 23% Cold Dark Matter, and 73% Dark Energy. The
geometry of the Universe is flat. It means that two parallel lines
will never meet, and that the fate of the Universe is that it will
expand forever...
