When they won the Cold War, the US declared themselves God’s own representatives on earth, people who have no responsibilities – only interests. They have declared those interests sacred. Now it’s one-way traffic, which makes the world unstable.
Light-year (Wikipedia)A light-year, alternatively spelled light year (ly), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the word “year”, the term is sometimes misinterpreted as a unit of time.
