Day/Night Ecosystem Simulator Concept. (addition) Have to work on the model and concept a little more but it can be done for sure. yearly rotation for the entire foundations including the water basin, daily rotation for half a darkened polarized hemisphere, rotating 15 degrees per hour. standing on the large rotating floor you wil not notice any motion if the circle radius is large enough (the closer to the outer edge you get, the faster the "sky" appears to move while, standing on the rotating circle, keep animals away from the edge and they will never notice), but it will optically appear the sun does exactly the same as we observe on earths surface now. this is how we can fool plants into growing at their best, as to what they are used to here on earth, or simulate growing conditions on other heavenly bodies to see if earth plants when taken there would or could survive, under the base its dome of course. Depending on the size, we can simulate multiple bacteria or ant colonies on different parts of land or in the water around the "land".
It all depends on how large a circle you escribe your new "earth" to be. lab researchers would get a perfect 24h view on their experiment as seen from above, allowing them to monitor their colonies and even act to influence them during the experiment. if we can build them larger and perfect the system we could scale these bases up for larger animals, see how they multiply undisturbed by humans etc.
Some animals can not procreate in captivity, this would sort of set them free in a large preservation base/lab. we could create condensation evaporation cycles, simulate day/night and the seasons all with a single convenient device. heat the glass, cool the foundations, create condensation falling down as rain over the entire project. tilting the device 5 degrees simulates the seasons, creates eb and flood, keeps the water moving and fresh. Maybe we can make the water basin have translucent glass walls, so we can even look in to the aqua marine life development, look into the "aquarium" and "terrarium" to study marine life without disturbing them, all from the outside of the experiment. we can even easily record video of these events happening inside the simulator. Rotating the base floor basin counterclockwise will not affect any time, will not reverse time, will not change anything at all but direction. Elevate or lower the lights altitude to simulate seasons, together with a 5 degree tilt of the entire base floor, towards or away from the "sun", creating longer and shorter daylight periods for different locations ON the base floor, depending o the total radius of your working area. apply several known growing frequencies onto the outer domes glass wall. experiment with different settings, different types of light, moisture and heat settings. Polarized (electrically wired, reinforced) glass (panes to be created on location using heat, sand and other locally available silica-like matter) can dim the total amount (percentage) of source light able to penetrate the glass, thereby creating a location on the base floor called "night" where less light is allowed to shine through, giving plants or animals alike a clearly defined resting period.
We can even have this percentage be variable over time, simulating different types of skylight. similar to how we can dim electric windows these days. Finally if we created a special type of structure or lattice (spread out diamonds or crystals) woven into the glass structure or glass panes forming the dome, we can optimize the spread of light onto the base floor, (reflections of shimmering light appearing as "stars" during the "night" part of the simulation) have a cascade of light inside the simulator, lighting up the entire sky "as if" "overcast", somehow. or, we print a very small working table model, place a circular map of the world on the base floor, and use it as a nice table world-clock, allowing one to read off the time off of the base ring and the solar highlight marking the noon location for any location, functional on basically any location in the world to read the world time.
what if we ever discovered we lived inside the "eye" of the lord, then would you change your ways?
