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”
Kenichi Omae (大前硏一) is a Japanese economist. He confidently asserted that there are only three ways to change our lives: 1. Spending time differently 2. Changing where we live 3. Making new people. Making new decisions is the most meaningless. Doing all three simultaneously is “marriage and divorce” and “changing occupation.” - Joseph’s “just my thoughts”
