无人知道答案的问题（完整版）

在最新一期TED-ED系列中,为了促进求知欲好奇心 , TED 主管Chris Anderson 将与大家一起分享他孩童时代的一些离奇想法,他的这些怪异问题至今无人可答（介绍"无人知道答案的问题"系列),动画设计 Andrew Park (http://www.cognitivemedia.co.uk)

Some questions fascinate precisely because no one knows the answers. The known universe holds at least 400 billion stars in the Milky Way and up to 100 billion galaxies, yet physicists now propose there may be countless or even infinite universes. Meanwhile, the search for life beyond Earth remains fruitless, even though there could be 50 million potentially life-friendly planets in our own galaxy alone. Exploring these grand unknowns pushes humanity to the very edge of understanding, inspiring wonder and new ideas.
