1, in the near future, if humans really invented the light-speed spacecraft, they can easily fly out of the Milky Way. In fact, we have to say that the space of the Milky Way is beyond our imagination at present, and it is precisely because of this that we can think that the Milky Way is boundless. Of course, in the near future, if the light-speed spacecraft is really invented, it should break our cognition at this time, and we can easily fly out of the Milky Way and fly to a larger universe to understand the phenomenon of the universe.
At present, the Milky Way is an unimaginable space in our cognition, and the dream of flying out of the Milky Way may come true in the near future. In fact, we have to say that technology is constantly refreshing people's cognition, and because of this, at present, the Milky Way is an unimaginable huge space in our existing thinking. Of course, in the near future, if we really realize the pilot of the speed of light, we can easily fly out of the Milky Way, and the Milky Way is no longer our destination. We are concerned with the larger universe.
3. Future technology will change people's cognition. Because of the continuous development of science and technology, people can better explore the larger universe. In fact, I have to say that every technological innovation can change people's cognition, and with exploration, discovery constantly refreshes people's cognition. It is precisely because of this that in the future, human beings can also use the light speed spacecraft to understand the larger universe, and can break through the upper speed limit and realize the navigation of the universe.
In fact, for us, the level of science and technology in the future is endless, and because of this, we might as well imagine that after flying at the speed of light, interstellar travel may also become a reality, or it may fly out of the Milky Way and learn the truth of the universe in a larger universe.
