When stepping into deep space, are humans still the species we know?

We have fantasized many times about the process of mankind entering deep space. Stargate, warp speed, hibernation technology, superluminal spacecraft... In these fantasies, human migration from one planetary system to another is like a journey. But if these fantasies of convenient travel do not come true, and human beings have had to leave their homes, in such a vast starry sky, when the travel process is extended to hundreds of years, thousands of years, it can still be called Travel?

Hundreds of years have been enough to turn human culture upside down. Human beings will become a real cosmic civilization and produce the culture of cosmic civilization. What we have to choose is how to control this cultural orientation to make it more suitable for the life of the universe. In the past, we have tried countless times to simulate the earth's environment in the universe. But human beings cannot go on a long journey in their infancy. The living environment shapes the nationality of a nation. During the long voyage, we should realize that deep space is not the scenery outside the window, but the land under our feet. The sense of security brought by the spacecraft is false, and the simulated environment will be broken. If you want to survive in the universe, you have to walk on thin ice all the time.

The concept of design is clear. I want people to understand that the new land under their feet is the whole universe. So what is this land? There is no gravity in space, it doesn't matter up or down, there is no foothold, and there is no concept of land. But I think that people are gravity animals, and it is impossible to maintain health in a long-term weightlessness state, so simulating gravity is a must in such a spacecraft. The most common concept is the cylindrical structure, which uses centrifugal force instead of gravity. Then I have the design point to use the cylinder that provides centrifugal force as land and turn it into a transparent material that directly projects the outside universe.
With this transparent cylinder as the core, I considered the layout of the power area, command area, industrial area, agriculture and living area, and after deduction, I turned it into a spaceship.
