Why is it that humanity may never get out of the galaxy? Scientists reveal the galaxy you didn’t know
In the early 20th century, from the theory of relativity proposed by Einstein, we realized that the speed of all mass objects cannot exceed the speed of light. So in the next 100 years or so, people also used factual evidence to prove that Einstein said it was true. Mankind has not yet built a spaceship that can reach the speed of light. Even if it is infinitely close to the speed of light, it is extremely difficult. But humans obviously will not give up. Humans have long spied on the existence of countless stellar planets and countless terrestrial planets in the universe using space telescopes. If humans give up at this time, they will never touch the highest civilization.
In 1916, the Austrian physicist Ludwig Felem first proposed about worm hole Concept. He said that there are a lot of time and space in the universe that are twisted. If humans can open the entrance to the wormhole, then humans will travel through millions of light years in the shortest time, and it is even possible to reach the interstellar boundary, just Unfortunately, humans have not found wormholes so far.
This means that humans have a limited time , May never be able to leave the galaxy. After all, compared to the solar system, the Milky Way has a diameter of more than 150,000 light years, and even more than 200,000 light years. Even if you travel through the Milky Way at the speed of light, it will take at least 200,000 years, and human life will only take a few decades. Humans have not been drifting in the galaxy for such a long time. Perhaps this is why scientists say that humans may never get out of the galaxy. Since humans are trapped in the solar system, scientists have mentioned many times that humans flew out of the solar system, and rarely mentioned the Milky Way, but the Milky Way is the real barrier that traps humans on the earth!
The Milky Way appears in space Oval disk shape. There are more than 120 billion stars here. The sun is just one of them. It can be seen how many planets in the Milky Way are similar to the solar system. Not to mention billions of planets, hundreds of planets can be found in the galaxy even if they are very similar to the earth’s ecological environment. The Milky Way was born much longer than the Solar System. Almost immediately after the Big Bang occurred in the universe, the galaxy was born, so the galaxy may have lived 12.5 billion years of age Too. But this does not mean that the Milky Way is special, because in the vast universe, there are still many galaxies as old as the Milky Way.
The area near the center of the Milky Way is mostly some old stars, and the planets farther from the Milky Way are similar to the sun, which belongs to the new young star system. This shows that the Sun is totally unworthy of mention in the Milky Way. Even if there is an ecological planet Earth in the solar galaxy, what about it?
Humans want to leave the solar system, there are still ways to do it. In 1977, the United States launched the Traveller One toward the outside of the solar system. At present, the probe has been sailing in space 43 Years, but still did not leave the solar system. According to NASA, Voyager 1 is likely to be close to the boundary of the solar system. Once Voyager 1 leaves the solar system, it will completely lose contact with the earth. It is not difficult to find that even if humans leave the solar system, it will take nearly 50 years, not to mention the difficulty of humans leaving the solar system in a spaceship will increase exponentially. Especially when taking a step back 10,000 steps, even if humans finally leave the solar system in a limited time, they can’t spy on the most mysterious and unknown things in the universe. Only a galaxy has trapped humans on the earth forever.
The Milky Way is nothing but the universe It is just a small galaxy in the middle. There are also triangle galaxies and fairy galaxies near the Milky Way. Humans cannot leave the Milky Way, nor can they cross fairy galaxies and triangular galaxies. Besides, there are more important local galaxy groups in these galaxies and This super galaxy cluster. It has to be said that there are people outside of people, and there are days outside. When humans were first born on earth, they were frogs at the bottom of the well. With the continuous improvement of civilization, humans began to walk out of this world and pry into the distant starry sky, but I did not expect that the more humans understand the space universe, the more they find themselves powerless.
Who made the universe expand after the big explosion of 13.8 billion years ago! And the universe expands faster than the speed of light. Even if humans really reach the speed of light, they will never get what they want. But human beings do not have to be discouraged. I believe that as long as humans do not give up, they will eventually be able to do something else. It may only be a matter of time before humans leave the galaxy, maybe hundreds of years, thousands of years? I don’t know how you think about it?
