How many sun-like stars are hidden in the Milky Way?

Inside the Milky Way, there are at least 200 billion sun-like stars. As we all know, the reason why the earth is in the vast sea of stars? Stand out? Becoming a cradle of civilization and a paradise for creatures is largely due to the efforts of everyone in the solar system for billions of years. Work? .

It is the light of the sun that gives us the opportunity to sit back and relax and put into production and life. Even if modern human beings enter the information age, they still have to breathe against the sun to survive.

However, looking at the vast galaxy, isn't the sun? Island? . According to the current Hubble volume, the size of the Milky Way is at least about 200,000 light years. Therefore, there are countless stars in the Milky Way that are similar to the sun. According to Mr. Wayne, a professor of astronomy at Columbia University in the United States, the data provided in 20 17 years show that;

The total mass of the Milky Way is one trillion times that of the sun. It can be seen that the sun and the earth are just a drop in the ocean compared with the whole galaxy. At the end of his published paper, Professor Wayne thinks that the overall conclusion of galaxies is derived from the current model;

There are about 300 billion stars, and 250 billion stars have small galaxies. Let's narrow it down to something like the sun? Yellow dwarf? For small galaxies, it is 200 billion. In other words, there are only a handful of solar systems.

Hearing this, many friends may think? Think about it and be afraid? Yes In that case, the number of civilizations in the Milky Way probably exceeds our imagination. However, according to the current research;

We didn't find any trace of civilization within the range of 10 thousand light-years in diameter. That is to say, inside the Milky Way? Aliens? It may be far away from us. So, we humans don't need it yet? Worried? Yes!
