欢迎来到宇宙之旅：对话一课！

本节帮助你了解这门课程是关于什么的，谁在讲这门课以及其他探索这个话题的方法。现在就和你的同学们打个招呼吧~

导论 –宇宙的历程：对话

宇宙的进化发展推动新时代替代旧时代，这也是此时此刻正在发生的。我们正从工业时代进入地球历史的一个新时代。

宇宙的开端：星系，恒星和太阳系

要有碳和氧就要有恒星，而要有恒星就要有星系，所以想要有一双手先要有整个银河系。了解宇宙的本质是我们进入新时代的第一步。

生命的出现，学习和人类

我们讨论了20亿年前的氧气危机，细胞内共生这一创造性方案解决了这个问题。我们还讲了现在这个时代的次贷危机，警惕他们再次发生。

全球化: 群体、城市和经济

独立质子会快速衰退，而质子中子结合却可维持长期稳定，这样的故事告诉我们：生态城市中将产生一种协同效应。我们可以猜测，这种相互促进的新型关系会带来一种全新的活力。

体化知识: 食物，能源和健康

理解了宇宙的自组织特性后，我们再来想一想星系。正是星系的螺旋结构才能产生恒星。椭圆星系没有这种螺旋结构，因而也失去了产生恒星的能力。水，土壤和空气年复一年地产生生命。特别是土壤，它是一种动态结构，需要三十亿年时间才能形成。我们现在就拥有土壤，只要能维持它的健康和完整，就能源源不断地产生食物。但如果我们破坏了土壤或是海洋的动态结构，就要等上数十亿年才能让它们恢复。

地球社区的出现：教学和创艺

人类追求更高的生命意义，永远追求幸福和成就.其中一种实现目标的方式就是教导他们的孩子我们这个宇宙的全貌.不单单是我们的科技、我们的科学、我们的艺术和娱乐，还有宇宙的故事本身，以及我们身边正发生的一切.
