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”
Humans are bound by their experiences. The extent and depth of these experiences shape how time is perceived by individuals. Recognition occurs within a person’s unique time framework, which is distinct from physical time. Even sharing the same age, individuals experience time differently. In the absence of challenges, the scope of one’s experiences remains constrained, leading to a limited perception of time. Imagination draws from experience, broadening only through facing challenges and making attempts. Observing and immersing oneself in various experiences, such as travel, becomes valuable forms of learning that don’t require a teacher. - Joseph’s “just my thoughts”
