Yael, do you notice the days changing length over the course of the year?

雅埃尔，你有没有注意到一年中每一天的长度在改变么？
Sure, Don, it stays light later in the summer and gets dark earlier in the winter.
当然了，唐，夏天白天长些，冬天天黑得早些Ps)aB*bT.z+IsBsaW4Y。
No, that's not it. I mean the whole day feels longer.
不，我说的不是这件事tBqas^BEUbE。我的意思是一整天感觉变长了些yS;0NUk9zQt_M^,。
I'm not sure that's possible, Don aren't days always 24 hours long?
我不确定它是不是真的，难道一天不总是24个小时么？
Well, it actually takes 23 hours, 56 minutes, and 4 seconds for the Earth to rotate on its axis.
其实，实际上，地球绕地轴自转一周需要23小时56分零4秒7wHIJ9hOEp]q。
But in fact the Earth's rotation is slowing down all the time because of the gravitational pull of the moon.
但实际上，因为有月球的万有引力作用，地球自转一直在变慢&)9ZefOBLUc。
Does this mean that the days really do feel longer?
这就意味着一天真让人觉得变长了？

Nope. The moon slows us down by about two milliseconds a century, so that even 1 million years ago days were only twenty seconds shorter.
不JA5mrVy]@6obs。每过一个世纪，月球使我们慢了2毫秒%;H5q6Ba0;3pIIfRxg=b。因此，即使比起一百万年前的某一天，现在也仅仅慢了20秒UxI_4%ZtyJMOm。
I doubt I would have noticed that.
人们会注意到么？
Maybe not a million years ago. But 400 million years ago days were 21 and a half hours long, which you would have noticed.
可能不是一百万年前，而是4亿年前的某一天，当时一天长21.5小时，这样你可能就能注意到4z[OUACoy;+P。
What you really would have noticed is that the time it takes the Earth to get around the sun hasn't changed, so that back then there were 400 days a year.
你真正能意识到的是：地球绕着太阳公转的时间没有改变，所以那时一年有400天8IBVhQ*qzA.。
Scientists have found fossil evidence from tropical corals that existed at that time, and they have about 400 daily growth rings per year.
从存活在那时的热带珊瑚中，科学家已经发现了化石证据]hG8N,[lTYq@V。它们每年大约有400个生长日轮-^0dt10+SUqC(Rz3Z。
So someone was enjoying all those extra sunny days.

所以过去的人能享受这些多出来的日子f[z8.Qdwnh.wc6&et。
