The most beautiful galaxy in the world
We know that human beings live on the Earth, and the Earth belongs to the solar system, and the solar system is in the Milky Way galaxy, so we are in the Milky Way galaxy, so the most beautiful galaxy recognized by the world is the Milky Way galaxy. The Milky Way has a special significance because it is the only highly intelligent life form found in the universe so far, and it is also the barred spiral galaxy where the solar system is located, which is a kind of vortex galaxy with an elliptical disk shape and a huge dial structure with four clear spiral arms, which looks mysterious and beautiful.
Is there an end to the universe?
Although the universe looks vast and boundless, it is possible that there is an end to the universe. Some scientists believe that the universe cannot keep expanding, so this also means that the universe should have a certain end, but that end is more distant and beyond the reach of human eyes, so we humans cannot see the end of the universe. Since the universe is a material world, in a state of constant motion and development, not subject to human will, the universe should be finite, not endless.
Is the entire galaxy only human?
The current study found that there may be only one kind of advanced intelligent civilization in the galaxy, but there are countless planets in the galaxy, the Earth is only one of them, and the other planets in the galaxy are not fully studied, so it is likely that there are advanced intelligent life forms in other places, but because they are too far away and not discovered by humans, so whether there are only humans in the galaxy is An uncertainty.
