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”
In a rapidly evolving technological market, companies thrive not by producing durable, long-lasting products but by continuously innovating new models. If car manufacturers create vehicles so robust that customers drive them for over 30 or 40 years, those companies risk failure. Therefore, product cycles are crucial in manufacturing: if they are too short, trust is lost; if they are too long, bankruptcy follows. Nevertheless, newcomers often aim to make them more robust. - Joseph’s “just my thoughts”
