How do we know that objects exist? We can see, touch, hear them.

To do this, we have to catch some force, moving from the direction of an object. Catch it with our eyes, ears, skin.

Once the force is caught, the mind will build a model of its source. And no matter how close we are to this source, we can never crawl out of our mind and touch it. The object is always only a model. What exists, is the force.

What happens when an unstoppable force meets another unstoppable force? This question seems much easier to answer.
