Hi, I'm actually a 13 year old boy ( I'm going to turn 14 in April). Whatever it doesn't matter very much. I do not have much deep education in all this, but I'm interested in cosmology and astronomy. Since I'm a new one and as I told I'm not so much, I sincerely expect your support and co-operation and I really do not want to see the use of any abusive words around my threads. And most importantly I might be disturbing all of you by posting some threads. Thank you.
