AE里时间线上面的3种关键帧分别是什么意思啊

那是有关一个计划或工程的进度时间表,用实际的工作和预计时间来表征计划的进度.

宇宙诞生之际形成了时间和空间,而空间可能是以多个平行空间的形式存在着.也就是说,我们现在只是存在与某一个空间,而每个空间都不会互相影响,一旦某个空间摧毁,也会影响时间和空间的规则.

在我看来,through time可以译成“过渡期”,in time可以译成“影响期”或者是“消退期”关键在于对in的理解,

相对时间在数学表述上是二维的,绝对时间线为它的一条坐标轴.二维图景中,相对时间线是可以弯曲的,可以任意蜿蜒甚至光滑打结.我说“光滑”是因为要考虑特定物质实体内部状态过渡有连续性,因此,相对时间线有渐变的品质.
对于孤立的物质实体而言,它的相对时间线是周期震荡的一个回环；而对大多数非孤立的物质实体而言,因为需要感知外部影响,内部物态变化将呈现不可预知的复杂轨迹,其表征的时间线就开始任意蜿蜒了.
时间旅行者回到过去改变历史后,时间线便出现分杈,分杈的时间线展开的是另一段历史.然而,如果我们能够回到过去,就可能破坏因果规律.于是,祖母悖论也被这样解释：由于时间与空间相关,因此祖母被害,世界因历史的改变被一分为二,从而产生时空的分枝,那么在这个空间里的我就不存在了,但另一个空间的祖母仍然存在,也便还有我存在.
（我分析了霍金的那一段,之后我觉得,就是从过去到将来,所有时间的集合体所构成的线状模型.是以线的形式,再三维中形象的把时间的连续以线的形式表现）
（我的知识水平还不够,查了老久,只能帮你这么多了,下面是网址,你有兴趣自己看看吧）

Yep,that's me
Yes,I do
Yep,and this
Are you going to read the whole thing
I'm a time traveller
Or I was ,I'm stuck in 1969
Quite possibly
afraid so
38
Yeah,People don't understand time
It's not what you think it is
Complicated
Very complicated
People assume that time is a strict progression of cause to effect but actually to a non-linear ,non-subjective viewpoint,it's more like a big ball of wibbly-wobbly ,timey-wimey stuff.
It got away from me ,yeah
Well I can hear you
Well ,not hear you exactly ,but I know everything you will gonig to say.
Look to your left
I've got a copy of the finished transcript .So it's on my autocue.
I told you I am a time traveller ,I got it in the future.
Yeah,yeah ,wibbly-wobbly ,timey-wimey.
What matter is we can communicate.We have got big problems now.They have taken the blue box ,haven't they?The angels have the phone box.
Creatures from another world
only when you see them
Lonely assassins ,they were called
No-one knows where they came from ,they are as old as the universe ,or very nearly.
They've survived this long as they have the most perfect defence system ever evolved.
They are quantum-locked.Thety don't exsist when being observed.The moment they are seen by any other living creatures ,they freeze into rock.It's a fact of their biology in the sight of any living thing they literally turn into s stone,and you can't kill stone.
Of course ,a stone can't kill you,either .But then you turn your head away ,then you blink and ,oh yes ,it can .Thas's why they cover their eyes.They are not weeping ,they are just can't risk looking at each other.Their greatest asset is their greatest cures.They can never be seen.The lonelist creatures in the universe.And I'm sorry .I'm very very sorry ,It's up to you now.
The blue box ,it's my time machine.There is a world of time energy in there they could feast on forever.But the damage they can do can switch off the sun.You have to sent it back to me.
And that's it .I'm afraid ,There is no more from you on the transcript ,that's all I've got.I don't know what stopped you talking ,but ,I can guess they are coming .The angels are coming for you,but listen ,you life depends on this ,don't blink ,don't even blink,blink and you are dead.They are fast ,faster than you can believe,Don't turn your back,don't look away,and don't blink .Good luck .

Ok this is all the doctor said in S03E10,hope can help you~

时间是肯定有的。说蚂蚁的世界只有二维，是因为他们的感官只能感觉到一个平面上的事物，
以上回答你满意么？
