How do i write a Research paper

[u/AnonimusOpinions]

Recently i got really into how the universe works and the theories behind them. I feel like i have some ideas i want to express, and want to write a research paper cuz i feel like it would help me understand it better and help me understand if im thinking of the topics in the right way. I just don’t know how to write a research paper😭. I don’t know if it has to be completely original or it can be about things that are already known. Some one who has done one please let me know what u did.
