How to survive in the galaxy

Recently, astronomers have mapped out the most suitable environment for life in the Milky Way in the past 13 billion years. The Milky Way is a dangerous place, full of stars and gamma-ray bursts, which may strip off the atmosphere of a planet and threaten life on the planet. An analysis showed that the safest areas around the galaxy have moved from the periphery to the center of the galaxy over time.

If we compress the earth’s 4.6 billion years of history to one day and see it all, it turns out to be like this…

Since the creation of words, the history of human civilization has been 6,000 years. Counting from the evolution to the early apes (capable men), the history of human evolution has been 2.5 million years. So, when we live on an old ball that has been about 4.6 billion years old since the birth of the solar system, I don’t know if you have thought about this question:if the”history” is slightly different since the birth of the earth, maybe we are not Will appear here.

When the sun”ends its life”, its volume will expand and change drastically. As a”red giant”, its surface will reach the vicinity of the earth’s orbit, and may even exceed this range, and the earth is likely to be destroyed by then.
