We can feel the beauty brought to mankind by the earth at every moment, and this beauty will last for a long time. But as the river continues to flow forward over time, the appearance and environment of the earth will slowly change.
What will our earth become in billions of years?
The earth at that time may have long been beyond recognition. If we travel to the earth billions of years later, it is difficult to believe that it is the earth, because billions of years later, the beauty of the earth has long disappeared, the average temperature has risen to nearly 50 degrees, the oceans have all evaporated, and the earth has completely become a dead and silent planet.
As the sun gradually transitions to red giant , the volume and brightness will become larger and larger. The habitable zone in the solar system also begins to expand outward, first reaching near Mars , then Jupiter and Saturn . Mars and Jupiter Saturn's satellite family will become new habitable planets.
3.5 billion years later, solar radiation continues to increase, and the temperature on the earth's surface exceeds one thousand degrees. Such a high temperature is enough to melt the rocks, and the earth will become what Venus is today.
At the same time, Milky Way will also experience great turmoil. It will expand with the Andromeda galaxy and then merge into a larger galaxy.
About 5 billion years later, the sun has reached its maximum size and becomes a red giant, swallowing up nearby Mercury and Venus. The moon family of Jupiter and Saturn became a new habitable planet, and if humans still existed, they would build a second home there.
About 8 billion years later, the sun becomes an white dwarf , the size of an earth. The white dwarf still emits a faint light, but it is far from enough to illuminate the Earth and the solar system, and also declares the death of the sun.
After one hundred billion years, the expansion of the universe has significantly accelerated, and the distance between galaxies is getting bigger and bigger.
4 trillion years later, the star closest to the sun, Proxima is also heading for death.
12 trillion years later, all the stars we see are coming to an end, and new stars and planets are constantly born, but the speed and frequency of birth are slowly decreasing.
trillion years later, the last star in the universe also disappeared, and only the longer-lived neutron star remain, white dwarfs and black holes. Without the illumination of stars, the universe is completely shrouded in darkness!
trillion years is an unimaginable long for humans. In terms of the lifespan of less than a hundred years, a trillion years are almost equivalent to eternity.
This is a good thing for humans. Because this means that humans have plenty of time to develop technology and enjoy a good life.
Before the universe is approaching its end, humans have plenty of time to explore the universe, fly out of the solar system, the Milky Way, and even fly out of the universe where we are, to reach a younger universe, the so-called parallel universe .
Although the concept of parallel universe is more of a conjecture, many scientists firmly believe in its existence. If humans want to continue civilization to an infinite future, flying out of the universe may be the only choice.
