Peretz writes "NASA has found evidence reinforcing a theory of what took place post-Big Bang and time expansion. They claim: 'Over the course of millions of years, gravity exploited the density differences to create the structure of the universe---stars and galaxies separated by vast voids.' Thereby creating a 'structure' to the universe -- a kiddush cup. '...finds that the first stars---the forebears of all subsequent generations of stars and of life itself---were fully formed remarkably early, only about 400 million years after inflation. This is called the era of reionization, the point when the light from the first stars ionized hydrogen atoms, liberating electrons from the protons.'"
