podcast##推荐# Are We Alone in the Universe? from Science Rules! with Bill Nye

昨晚在湖里躺着看了星星，回家路上，茫茫夜色，听的这集。

可以算是brain workout了。脑子里一直在跟着想象宇宙。宇宙无限扩大，到哪里？我们怎么测到宇宙的大小和年龄的？黑洞，dark matter？

我完全是文盲状态...😳😳

希望我下辈子能像这期的嘉宾天体物理学家Dr. Janna Levin一样聪明。[推荐]:《Are We Alone in the Universe? from Science Rules! with Bill Nye》(https://www.stitcher.com/podcast/stitcher/science-rules-with-bill-nye)
