Panama responded to Trump’s tweet about the Panama Canal. Then Trump responded by renaming the canal with “welcome to the United States Canal”.

Matter is sparse and rare in the universe. The scale of emptiness in the universe is staggering. Consider this: The Milky Way has a galactic volume of ~ 8 trillion cubic light years that contains on the order of ~100 billion stars. This is almost all just empty space filled with tiny points of light when viewed from a distance. How empty is the actual space? You can fit the total cubic volume of all the stars in the Milky Way into a cubic light year. Not just once, in fact, you could fit all the stars from 3 billion Milky Ways into a single cubic light year. What does this say about the rarity of matter within the Milky Way? It says that matter exists within the Milky Way at a rate of 1 part per 24 sextillion of empty space or 1 part per 24,000,000,000,000,000,000,000.
