The Coldest Place in the Universe is on Earth

Where do you think the coldest place in the universe is? It's easy to imagine the edge of the solar system or interstellar space, but the answer is actually inside a research lab on Earth. The naturally coldest place in space is the Boomerang Nebula, reaching about -272°C (1K absolute temperature). However, humans have succeeded in creating ultra-low temperatures in labs, close to absolute zero at below -273.14°C, or in the nanokelvin (nK) range, using laser cooling technology. In reality, a corner of a physics lab in Korea or around the world is much colder than the pitch-black void of deep space. Isn't it fascinating that humans are directly recreating the most extreme cosmic environments right here on the ground?
