| In the Nature we observe, the Universe is filled with dust and gas in addition to stars, planets and galaxies. |
| But of course it has structures in it, stars and galaxies and clusters of galaxies. |
| One thing we can say about this starting value is that it must be very specially tuned if galaxies are to form in time. |
| The resulting theory would be able to describe the behavior of the universe, from quarks and atoms to entire galaxies. |
| Soon her palm resembled a chart of lunar phases, four thin moons, their tiny scarlet crescents crossing the lines of galaxies and Fate. |
| There are a hundred billion stars in our galaxy alone, and there are billions of other galaxies. |
