#### Unscramble the Blue Letters

Now we owe the idea that space can ring like a drum to Albert eesniitn — to whom we owe so much. Einstein realized that if space were empty, if the uenivrse were eptmy, it would be like this picture, except for maybe without the helpful grid drawn on it. But if we were freely falling through the space, even without this helpful grid, we might be able to paint it ourselves, because we would ncitoe that we talreved along shtriagt lines, undeflected straight paths through the universe. Einstein also realized — and this is the real meat of the matter — that if you put energy or mass in the universe, it would curve space, and a freely falling object would pass by, let's say, the Sun and it would be deflcteed along the ntuaarl curves in the space. It was Einstein's gaert general theory of relativity. Now even light will be bent by those pthas. And you can be bent so much that you're caught in orbit around the Sun, as the Earth is, or the Moon around the Earth. These are the natural curves in space.

#### Original Text

Now we owe the idea that space can ring like a drum to Albert Einstein — to whom we owe so much. Einstein realized that if space were empty, if the universe were empty, it would be like this picture, except for maybe without the helpful grid drawn on it. But if we were freely falling through the space, even without this helpful grid, we might be able to paint it ourselves, because we would notice that we traveled along straight lines, undeflected straight paths through the universe. Einstein also realized — and this is the real meat of the matter — that if you put energy or mass in the universe, it would curve space, and a freely falling object would pass by, let's say, the Sun and it would be deflected along the natural curves in the space. It was Einstein's great general theory of relativity. Now even light will be bent by those paths. And you can be bent so much that you're caught in orbit around the Sun, as the Earth is, or the Moon around the Earth. These are the natural curves in space.
