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”
Cognitive science states that humans communicate with 30% of "linguistic information" and 70% of "non-linguistic information." Suppose you study something to acquire information, focusing on it with conscious awareness. In that case, any activity you engage in unconsciously throughout your daily life is "playing." It is challenging to maintain focus on a task for an extended period. However, engaging in play adds enjoyment to intellectual pursuits, allowing for sustained attention. Studying in a limited capacity will only make you proficient in specific areas, but play can facilitate a more comprehensive and nuanced understanding. Parents often err by separating study and play, they are two sides of the same coin. - Joseph’s “just my thoughts”
