The universe we live in is empty mainly in terms of matter density. The protons and neutrons that constitute matter are called baryons, and approximately one proton exists in a space of 19.8 square meters. However, when the universe expands rapidly, the cosmic background radiation, known as a photon, is produced, resulting in two billion more photons in a grain of light. Since this light is a microwave, which has low energy and a long wavelength, it cannot be seen by the human eye. Therefore, humans, who only perceive visible light, consider the universe and the night sky to be dark. If there were aliens capable of seeing microwaves, the universe would be shining very brightly. The truth is that nothing has changed, but if the standards shift, it’s an entirely different story. - Joseph’s “just my thoughts”
You probably suspect that your decisions are reasonably based on your judgment. However, human decisions are made according to the rules and structures at that time. By changing the decision structure and regulations, humans make different decisions under the same conditions. If you make a mistake, you don't have to regret or blame yourself for making the wrong decision. But, if you fail to judge the regulations and structure of the decision, then you must reflect on the mistake. This is to prevent repeated mistakes. - Joseph’s “just my thoughts”
