Although we have created brilliant civilization on the earth, we are doomed to be unable to conquer the universe. For human beings, the universe is always mysterious and vast, but this does not stop human beings from exploring the universe. As human beings enter the era of science and technology, we have launched many detectors and satellites into the universe. They have taken a lot of photos. Through these photos, the universe is not so strange to us.
The earth is the habitat for human survival, but there are still many places that human never set foot on. In the eyes of mankind, the earth is boundless, but in the universe, the earth is as small as a grain of dust. If human beings could enter the universe and look back at the earth in the distant depths of the universe, what would it be like?
What did Voyager one photograph?
The answer to this question is Voyager 1, which was launched in 1997. Its journey has been very smooth. It has not only successfully visited Saturn and Jupiter, but also sent back a picture for mankind. This photo was taken on February 14, 1990. It’s human Valentine’s day on earth, so many netizens tease that it’s actually a Valentine’s Day gift from Voyager 1. The location of this photo is 6.5 billion kilometers away, and it is also the last photo sent back by Voyager 1. Originally, it was thought that it was a gift from the universe, but scientists were worried. What did Voyager 1 take?
The following picture was taken by Voyager 1. If you don’t observe it carefully, you will find that it’s dark and you don’t see the blue planet at all. In this picture, the earth is hard to notice. Looking back at the earth from 6.5 billion kilometers, the earth is a small light spot. If Voyager 1 flew out of the solar system, maybe the earth would not appear in the picture. Although the earth is vast in human heart, it is invisible in the universe. At present, the range of the universe observed by human beings is 93 billion light years, which is an astronomical number for human beings and an altitude that can not be reached in a lifetime.
So many scientists feel inexplicable frustration when they see the first thing in this picture. Many people are pessimistic and despair. The earth photographed only in the solar system is a small light spot, not to mention the vast universe. Is it really doomed that human beings can’t get out of the solar system?
If we want to get out of the solar system with the current scientific and technological means of human beings, it’s really impossible. If we can continue to increase our R & D efforts and achieve a qualitative leap in civilization, after human civilization reaches level one, we may conquer the solar system as soon as possible.
