There are moments in our lives when we're just left in awe (敬畏). For me, these moments include when I found out that Jupiter is 121.9 times bigger than the Earth, and that Qomolangma, the Earth's highest mountain—if thrown into the ocean upside down—wouldn't be large enough to fill the Mariana Trench (马里亚纳海沟), the deepest place on the Earth.
But none of these moments compares to this one: when scientists revealed (公布) the first - ever picture of a black hole on April 10, 2019.
What you see in the picture might be only an orange ring—a blurry (模糊的) bit of orange ring even—but it is in fact a black hole and is 55 million light years from the Earth. And it's bigger than anything we know of. The Sun doesn't even begin to compare with it. Its mass (质量) is 6.5 billion times that of our star.
It got me wondering: How many more black holes are there? What lies another 100 million, or 1,000 million, light years away? And what does the size of the universe mean to us—tiny beings on a tiny planet?
But don't get me wrong. The news isn't supposed to be discouraging at all. After all, it is in contrast to the size of the universe that human beings can see how much they've achieved.
Just think about it: we're flesh - and - blood creatures, and yet we managed to extend (延伸) our sight by building telescopes that "see" millions of light years away. These telescopes are located in eight places around the world, and scientists from 20 countries worked together for two years to process all the data before finally bringing the image to us.
It's true that we tend to feel awe in the face of forces that are much bigger than us. But perhaps we should hold ourselves in awe as well, for all that we tiny human beings have learned about the universe.
