I've heard many theories like object with mass bends the space-time and causes object to fall for it. If that's true then the Earth should end up being colliding with the Sun right? , because the Earth's mass is 1/1 million of that of Sun according to my knowledge. If we take Earth's mass as m then Sun would be 1mil m, so would m's gravity really matter to 1mil m? I don't guess so, I dont think the theory explains quite of it. There is also another question I would like to put up, I'm sorry its not in the heading but, can this statement be true "Gravity can neither be created nor be destroyed". I've tried searching it in google and everywhere else but I wasn't able to get a satisfactory answer.
