futurama中的时间悖论
时间悖论最为著名的“时间悖论”一般称为“祖父悖论”：
某人回到过去，在自己父亲出生前杀害了自己的祖父。既然祖父已死，就不会有其父亲，也不会有他；既然他不存在，又怎么能回到过去，杀死自己的祖父呢？
与之对应的，既然有回到过去的悖论，也会有到达将来的“先知悖论”，表达如下：
某人到达未来，得知将发生的不幸结果A，他在现在做出了避免导致结果A的行动，到达结果B。那么结果A在未来根本没有发生，他又是如何得知结果A的呢？（既A与B不可能相遇的悖论）
就严肃的物理学理论而言，爱因斯坦的《相对论》指出，的确存在不违背已知的物理法则改变时间的可能性。但更多的只是一种科学幻想。为了解决“时间悖论”，也有多种假设，比如比较盛行的“平行宇宙”假说，认为我们的这个世界在宇宙中还有许多相似的“克隆世界”，当某人回到过去时，他就进入了另一个平行世界（即未来因为他的行动已经改变的世界），再也不可能回到原来的世界。 占楼～有空继续补充

[[i] 本帖最后由 19001900 于 2008-7-21 19:10 编辑 [/i]] 时间悖论有很多呀。而且导演是个物理强人呢。他相信而且崇尚平行宇宙理论，很多集都提到宇宙边缘和平行宇宙，就是那个戴草帽的教授= =不过FRY是有够恶心的……

小玲，借用了一下你的图。上传的附件太小～偶在2楼转成大图了页:
