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”
If a New Zealand fisherman catches a seabream in New Zealand, he makes a profit of $9 per kilogram, but if a tourist catches it, $88 goes back to New Zealand. This is because to fish a seabream, the tourist has to spend money on flights, hotels, and all sorts of rentals. The opportunity cost and value-added will change as B2B becomes B2C. - Joseph's "just my thoughts"
