The last photo taken by voyager-1, 6.4 billion kilometers away from the earth, has aroused people’s deep thinking!

With the development of science and technology, people’s curiosity about the universe has become more and more serious. In the past hundred years, many countries have launched probes into the universe, hoping to solve the secret of the universe. So far, only two probes have flown farthest, namely Voyager 1 and Voyager 2. In the process of exploring the universe, Voyager 1 sent back a number of photos, one of which made people think deeply. Why?

In 1977, Voyager 1 embarked on a formal exploration of the universe. The dream of mankind is to leave the solar system, and Voyager 1 carries this hope. In 1990, Voyager 1 sent back a large number of photos and successfully completed the exploration mission within the Department. At that time, NASA screened the photos it took, and one of the most inconspicuous photos attracted the attention of scientists, which caused a deep sense of powerlessness.

Photos taken

This photo is dark and full of glare, but scientists circle a small light spot in blue, which is the earth we live on. It took this picture 6.4 billion kilometers from the earth. From this, we can see that the earth is so small in the universe that it can’t even compare with a grain of dust. It’s hard to imagine that people’s food, living and reproduction have to be carried out in this small blue dot. It’s really powerless.

6.4 billion kilometers is an astronomical number for human beings, but dust has not been counted in the whole universe since last year. At present, we have created highly developed scientific and technological civilization, but it can not support us to go out of the solar system. What are we doing for?

Can man recognize the universe?

After seeing this picture, many people feel that what human beings do is powerless. Does the universe really have no boundaries? 13.8 billion years ago, the explosion of a starting point formed the present universe. In the evolution of hundreds of millions of years, the universe is still in a state of constant expansion. According to the data of scientists, the boundary of the universe that we can determine is 93 billion light-years. What kind of world is beyond 93 billion light-years that we can not detect. Maybe the area we’re looking at is not even a single dot in the universe.

Therefore, some people think that human beings can’t get out of the Galaxy after so many efforts. Are human beings imprisoned? The sky that human beings look up and see is the largest area that they can see. This view seems crazy to us, but we can also understand that human beings have sent many signals to the universe, but they have not responded. Maybe human beings are really lonely in the universe. If we can really cross the solar system and enter the universe in the future, is it the beginning or the end for us?
