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”
Victoria’s Secret once created underwear worth 1.9 million USD, adorned with diamonds and jewels. Of course, wearing such underwear in real life is impractical and may not sell, but once Victoria’s Secret produces it, media outlets worldwide will promote this underwear. When considering the promotional impact, 1.9 million USD is not wasted as a publicity expense ; the cash may be gone, but the jewelry-adorned underwear remains an asset, and brand promotion occurs globally, making it a genuinely profitable venture. Moreover, the existence of 1.9 million USD in underwear means that even if Victoria’s Secret products carry a higher price than competing brands , consumers may feel less price resistance . Spending money wisely is just as crucial as earning money. To understand the relationship between costs and assets , one must learn accounting . - Joseph’s “just my thoughts”
