I'm starting to get (Already am) really annoyed at how it is impossible to find an answer to what gravity is. For years (yes YEARS) I have looked for an answer to why objects are drawn to each other. Since I'm posting the question here it is kind of obvious that I have not found the answer yet. I have searched and searched on Google and asked every physicist and physics teacher I've met but no one seems to have a clue. Of course I've heard all about this curved space-time and I think I got a pretty good sense of what higher spatial dimensions are.
Now every video on YouTube and every article on the subject, all of them says in great headlines: Gravity explained!... Every time I watch they give the same example every time. The blanked, the big ball and the small ball. The blanket represent two-dimensional space. The big ball a planet and the small ball a satellite. Then they place the heavy ball on the blanket so it bends and the small ball is put into orbit. Now I don't have any problems with visualizing this in three dimensions but I have two big problems.
1: Why is the object bending space time at all?
2: Why does that create a force between objects?
I would really like a answer to this. I have waited just for too long for this question. Now I would like if you don't post some equations, that only a professor in physics can understand, to explain. Now don't hesitate to give examples of a two-dimensional universe since that seems to be the only way to explain it visually.
