How small are we, and how short is our life?

The observable universe is 96 billion light years,

The diameter of the Milky Way Galaxy is 200,000 light years,

The diameter of the solar system is 1 light year,

In 1977, the farthest-flying spacecraft launched by humans, the Explorer, has flown 18.8 billion kilometers so far, and has not yet flown out of the solar system.

There are 2 trillion galaxies like the Milky Way in the universe,

There are 400 billion stars like the sun in the Milky Way,

The sun is 1.3 million times larger than the earth.

There are nine planets in the solar system,

Among them, Jupiter is 1,300 times larger than the earth.

The earth is just a speck of dust in the universe,

We are the viruses and bacteria on this speck of dust.

The earth is currently 4.5 billion years old.

The earliest human Yuanmou Man appeared 1.7 million years ago.

China has a history of 5,000 years,

The human life span is 100 years.

We are very small, very small,

Life is very short, very short,

We bid farewell to this world in a minute and a second.

We use our feelings to warm each other before death arrives.

We measure our own value by the degree of satisfaction of our desires.

Pessimistically speaking,

We live proudly, but we are nothing. #BTC☀
