巨大的渺小

Small also Huge

How do you measure a thing which is huge or small? How do you measure a thing which is heavy or light? Human appeared on earth for a very short period compared to the history of Earth for approximately 4.6 billion years. Compared to the nearly 14 billion years history, the history of Earth is even shorter. Earth is one of the planets in the Solar System, and there is one star in solar system solely. In milky way of galaxy, there are around 100 billion to 400 billion stars. You might think milk way is huge enough, while milky way is one of the galaxies in the universe. Scientists estimated that the universe contains more than 200 billion galaxies. Human kind looks like a micro-dust in the universe. We thought we are dominating to the earth in the universe, but we are totally ignored by looking from the infinity universe. Out concerns daily seem bored in front of the universe. However, each of us is a unique individual in 7 billion world population. And there is a universe of cells living in our body, the recent estimate shown that the number of cells in the human body is around 30 trillion. Those tiny cells are just like galaxies lurking in our bodies. Is humankind huge or small? My mind has a universe, the universe is inside my mind. The earth might be big for us, it is small in the galaxy. My body might look tiny, it is huge enough to contain trillion cells.
