Wit M Theory, it seemed at last there was a theory which might explain everything in the universe. But before they could decide if this was true, the scientists need to know about this new eleventh dimension. It quickly became clear it was a place where all the normal rules of common sense have been abandoned. For one thing, it is both infinitely long, but only a very small distance across.
That eleventh dimension, well at its maximum size, could be something like a trillionth of a millimeter.
第十一維度,在其達到最大值時,可以是一萬億分之一毫米。
Well, this is tenth the minus 20 of a millimeter, that's taking a millimeter and dividing it by ten with 20 zeroes after it. So, that's very, very small.
That means that it exists only one trillionth of a millimeter from every point in our three dimensional world. It's closer than your clothes to your body, and yet we can't sense it. In this mysterious space, our membrane universe is floating. But first, no one could imagine how that worked. It began with Lisa Randall.
People look at rock climbing and it's of course very physical, but you'll soon find that you can concentrate on little thing. I like solving problems, I like games, I like figuring things out.
Randall had been fascinated by apparently inexplicable phenomenon, the weakness of gravity.
蘭德爾顯然對令人費解的現(xiàn)象,失重現(xiàn)象著迷。
There are various forces we see in nature. Most of them, we understand at some level. And then there's a gravity...
我們在自然界中看到有各種各樣的力。他們中的大多數(shù),我們已經(jīng)在某種程度上有所了解。而重力…
