So now the universe is chemically more complex.
And in a chemically more complex universe, it's possible to make more things.
And what starts happening is that, around young suns,young stars, all these elements combine, they swirl around, the energy of the star stirs them around, they form particles, they form snowflakes, they form little dust motes, they form rocks, they form asteroids, and eventually, they form planets and moons.
ps:开始发生的是,围绕着年轻的太阳,年轻的恒星,所有这些元素结合在一起,它们旋转,恒星的能量搅动它们,它们形成粒子,它们形成雪花,它们形成小尘埃,它们形成岩石,它们形成小行星,最后,它们形成行星和卫星。

So we've crossed a fourth threshold of complexity.
Exercises:
1.How was gravity related to density?
They have a positive correlation.
2.To swirl means to...
move in a circular motion.
3.what originally allow the universe to achieve new levels of complexity?
tiny temperature differences in different areas.
Fill in the blanks:
Gravity is more powerful where there's more stuff. So where you get slightly denser areas, gravity starts compacting clouds of hydrogen and helium atoms.
When very large stars die, they create temperatures so high that protons begin to fuse in all sorts of exotic combinations, to form all the elements of the periodic table.
Read and repeat the sentences:
1.And in a chemically more complex universe, it's possible to make more things.
2.the total complextity of the universe is growing because it contains more diverse materials.
3.The energy released by dying Stars allows new elements to emerge.
4.What you see here, the blue areas are about a thousandth of a degree cooler than the red areas.
5.Rocky planets like our Earth are significantly more complex than stars because they contain a much greater diversity of materials.
