here were only about 2,000 human beings left on Earth.

Now the earth is adding nearly 80 million people every year,

If you were standing at the equator of the earth when you were 6 years old,

Command all 8-year-old men and women on earth, every 1 second, a man and a woman must pass in front of you,

May I ask how old are the men and women who pass by when you are 300 years old?

quite a while,

Blackfoot shook his head,

Blackhead paused and continued:

Earth's civilization in 7017 AD can reach the second-level stellar civilization,

If humans do not become extinct within 3 million years,

Then in the 3 million years of the earth's Gregorian calendar, human beings will find a planet suitable for human existence,

In 1.5 billion years of the earth's Gregorian calendar,

The luminosity of the sun will increase a lot, causing the earth's climate to overheat,

Threatening the survival of multicellular organisms, the earth's environment will be Martianized,

At the time of 3.3 billion years of the earth's Gregorian calendar,

Mercury may hit Venus, causing the entire solar system to face a major collapse,

At 4 billion years of the earth's Gregorian era,

The Andromeda Galaxy, 220,000 light-years in diameter, and the Milky Way, 180,000 light-years in diameter, will collide,

Are we going to get out of the Milky Way before the Andromeda galaxy collides with the Milky Way?

The black head looked at the military division black heart and said: What should we do?
