如果跳出我们所在的空间来看，角动量可能还是守恒的，但是因为我们本身就处于这个
空间里所以不知道该怎么定义这个角动量吧？

发帖数: 12553 | 5 可以啊，凭什么老守恒？守恒是因为物理规律的对称性。动量守恒是因物理规律的空间
平移对称性，此点的运动规律和那点的相同。如果因什么原因这种对称破坏了，动量也
就不守恒了。所有的守恒，包括能量，都是这样。

They allow my starship to travel between galaxies in mere hours.
Cubert J. Farnsworth: That's impossible. You can't go faster than the speed
of light.
Professor Hubert Farnsworth: Of course not. That's why scientists increased
the speed of light in 2208.
Cubert J. Farnsworth: Also impossible
Professor Hubert Farnsworth: And what makes my engines truly remarkable is
the afterburner, which delivers 200% fuel efficiency.
Cubert J. Farnsworth: That's especially impossible.
Professor Hubert Farnsworth: Not at all. It's very simple.
Cubert J. Farnsworth: Then explain it.
Professor Hubert Farnsworth: Now that's impossible! It came to me in a dream
, and I forgot it in another dream.

发帖数: 43926 | 8 这个几年前就闹了。一种可能是作假，一种可能是没测准，一种可能是把电磁波漏出去
了。最后一种可能是物理学重大进步。
西工大还是哪里也有人搞这个。 |
