We know that matter is formed by energy. We do not know what kind of energy. We know that subatomic particles are energy fields. We know that these particles are emerging atoms and we know that the atoms of the elements are producing matter. Therefore, we know that all matter are energy fields. We know that biological units are made of matter. That is why we know that all organisms are energy fields too. Also we do know that thoughts are electric stimulations in the nervous-system and the herein nervous cells are transmitting these electric pulses. Therefore, we know that thoughts are results of energy movements in the material sphere. that is why we know that thoughts are energy fields too. Furthermore, we know that culture is made by thoughts of people. We know that culture emerges through the exchange of thoughts. Therefore, we know that culture is an exchange of energy by people. And we know that the energy emerges culture and all cultural products. Therefore, we know that all appearances, from matter to thoughts and culture, are energy. Finally, we know that our world as we know it is not really what we believe to know that it is. Therefore, the question is: What do we really know?
