Is it possible to create an artificial self-sustaining planet? self-sustaining in terms of Earth.
If the above question is possible then,can that planet be as large as a Galaxy and if not, can it be "of substantial size" relative to the Galaxy? Galaxy in terms of the milky way(our galaxy)
If the above is possible then, can that planet or whatever you may call it be able to function as a spheroid that exhibits the characteristics of both a galaxy and a planet?
I have to be honest that I am not what you may call a knowledgeable person in Physics nor in most sciences and I did neglect them in the past, but I it's not too late too learn! It is only until recently have I discovered passion for science and I'm glad with it, I just hoped I discovered it earlier. So please take this into consideration and if possible can you refer to me the sources, books, and any other resource that you use so that I too may be able to read, study and learn from them. Thank You!
