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”
It's dirty, but viscosity is the difference between tears and a runny nose. Viscosity is also the difference between saliva and sputum. Even for the same fluid, viscosity alone can make a difference in how people perceive hygiene. Viscosity is one of the few properties that can affect human emotions. It can revolutionize how we do business by changing how we look at it. - Joseph’s “just my thoughts”
