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”
Cotton needs 500 mm of water to produce cotton wool, and 1 kg of cotton wool requires 8,500 liters of water to fill 40 baths. A fashion company can make a pair of jeans from this. It needs at least 2,700 liters of water to create a T-shirt. This amount is enough for one person to use as drinking water for three years. Clothing consumption has recently increased by an average of 60% each year on Earth. The Aral Sea in Uzbekistan was the fourth-largest lake in the world, but it has now shrunk to one-tenth of its original size, as river water has been used to grow cotton due to increased consumption. Few people are concerned about how their consumption affects the global environment. - Joseph’s “just my thoughts”
