“Life without science is meaningless” Mr.Do

Here is the list of frequently asked questions about space science. Some of them have been answered based on many persuasively scientific evidences, which are divided into two groups. They are theoretical arguments and observational evidences. Leave a number of a random question in the comment box below, the best solution will be sent back to you as soon as possibly. You can also ask for the mathematical models related to some particular questions (if further investigation is possible on trinhmanhdo.com)
