As a result, Space is so wide and every planet, star or any other object has its own rules, physics, chemistry and other sciences, as we cannot apply what we learned and practiced on the earth to another planet, star or space unless if the humans can live there and do the same learning path as what they did on the earth and come out with different sciences than what they produced on the earth. But humans’ capabilities only allow them to learn from the place they were born and the events around them.

Gravity is what we feel and what gives us the weight to live and move on the Earth, so only the Earth can produce that force to be stored in our bodies and make the balance of life on its surface and other atmosphere and inner layers. We can only apply the rules and physics that we discovered, tested and simulated, and that is what I explained it on the above about the reality of the Earth’s gravity in Conclusion 3.3. Then, we can practice on the other planets and compare the results if there are any matches with our results by practice not by assumptions.

As well, the Sun orbits the Earth to provide us the four seasons and other events, as it’s fit for that purpose. The sidereal Day and Solar Day in the Heliocentric model will not be fit, as the Earth will complete one full rotation around its axis every day to the same point facing the Sun, as explained in Conclusion 3.1 & 3.2.

Finally, humans must concentrate on the environment where they live and the events happening around them, build the results by logic and by what we do practice, connect the outputs together and get out with tangible facts where human beings can understand and learn.
