do you require that a force actually be seen?
can you see any force at all?
Yes of coarse you can how else would you measure it. Seen does not mean human eye type stuff it means you can measure cause and effect.
tell me which force is not a hidden force?
Every other force except our four fictional forces in classical physics are directly measurable. Our four problem forces in classical physics are sometimes measurable in some situations but not all.
have you ever seen the force that is the result of a baseball bat hitting a baseball?
What I have never seen is a baseball fly off by itself without being able to attribute where the force came from. In your classic physics world gravity is dragging the ball down, so where is it getting the energy?
Now I need to give you a warning if we go down this path you are going to end up needing all the energy to be present at the start of the universe. This may come into conflict with your religious beliefs.
