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 2019, the coffee shop franchise Banapresso had 47 branches in Seoul, 35 of which were concentrated in the Gangnam and Seocho districts. There were even other Banapresso stores within 200 meters of each other. It was denser than Starbucks. 100% of orders were placed through kiosks and mobile apps. The elders thought it would be hard to place an unattended order, but when they tried it, they were impressed with how seamlessly they were connected to the register. An Americano costs KRW 1,500 (about USD 1.27). There was only one employee. Everything was ordered at the touch of a button and the coffee was served within 40 seconds. All the bread was made at a nearby headquarters and distributed in batches. Banapresso was the antithesis of a traditional coffee franchise. Its parent company is an IT company that operates a ride-hailing app. The same business can be completely transformed into a different business model, due to the interpretation and context. - Joseph’s “just my thoughts”
