But here's what they saw all those years ago.

Astronomers were looking into the sky to find distant galaxies, billions of light years away.

And they found this. At first sight it looks like two different galaxies.
他們發現了這個乍看之下，就象是兩個不同的星系。
In fact, they gave them different names, 957 and 561.

It's incredibly strange. It's almost like there are two twin galaxies,
怪異得出乎意料。幾乎就象是一對孿生星系，
but actually they find the light was absolutely identical for which one and they seem distance apart.
但實際上他們發現它們各自發出的光完全相同，而且它們似乎距離遙遠。
The interpretation is, this is a picture of one single galaxy.
解釋是，這是一張單一的星系的寫照。
This certainly confused the astronomers,
這當然把天文學家搞糊涂了，
but they soon realised that the cause of this strange cosmic mirage
但是他們很快就意識到了，造成這種奇怪的宇宙幻影的原因
had been predicted nearly a hundred years ago.

There's one man who, for me, really did think outside the box.

At the turn of the 20th century it was Albert Einstein

who opened our minds to a completely new way of looking at the universe.

Now, space is what we see around us - it's got length and breadth and height.
空間就是我們所看到周圍的一切——有長度、寬度和高度。
And time... well, it just ticks along.
時間嘛……啊，只是時鐘滴答不停而已。
But in Einstein's universe they're woven together into a fabric.
然而在愛因斯坦的宇宙里，它們交織在一起組成了構造。
Space and time are not separate, they're one and the same thing.
空間與時間不能分離，它們是同一個東西。
And that fabric is called spacetime.
那個構造稱之為時空。
