Force does not exist because it was never observed in a scientific experiment.

When I had completed my first year graduate classes in physics, I mentioned to a professor that "I still didn't really understand what a force was".  He suggested that perhaps I should be studying something else.  I'm still trying to understand what a force is.Maybe if I had been convinced that forces do not exist I would have had more time to watch television over these past 3 decades.By the way, my efforts in gravitation has been to rewrite Einstein's equations as Newtonian forces.

Very interesting. I think your professor?s remark means that force needs to be taken as faith in physics. I spent a lot of time trying to understand force as well. My conclusion is that force is nothing other than labels Newton attached to Kepler?s rule as I wrote here http://www.densytics.com/wiki/index.php?title=History_of_G. In this sense force does not exist.I couldn?t find such equations on your site. Although, Einstein started out by denying Newtonian force, apparently he only created a duality in physics. 

My professor's comment meant that the way you obtain tenure is by fitting in with the rest of the sheep and extending knowledge using only the techniques built from the current assumptions.  He was right of course.  The vast majority of physicists are doing basic engineering using theory that was written by a tiny minority, most of that a long time ago.

Well, if mass does exists, so force. Actually, the word "exists", instead of commoner "there is", was created by theologicians to discuss about this kind of topics.

Guest, Thanks, for your comment. I believe that both mass and force are definitions invented by Newton and they do not exist. Regarding your comment about "exist" I was trying be careful to use "exist" because I thought it was more scientific because in physics force both exists and exists not. I would appreciate if you explain why it is not good to use "exist" in this context. Thanks.
