The coldest known place in the Universe is on Earth!


The coldest known place in the Universe is on Earth!



The coldest place in the Universe is found right here on planet Earth. The moon can plunge to minus 378 degrees Fahrenheit. The deepest place in outer space is known to be minus 455 degrees Fahrenheit. The calculated 'absolute zero,' or the coldest that something could theoretically be is 459.67F. On Earth, we have had something that was 810 trillionths of a degree F above absolute zero.
The record-breaking lows on Earth were among the latest feats of ultracold physics. This extremely cold spot is not a natural occurrence. It was achieved as part of a laboratory study of matter at temperatures so mind-bogglingly frigid that atoms and even light itself behaved in highly unusual ways. Electrical resistance in some elements disappears below about minus 440°F, a phenomenon called superconductivity. At even lower temperatures, some liquefied gases become "superfluids" capable of oozing through walls solid enough to hold any other sort of liquid; they even seem to defy gravity as they creep up, over and out of their containers.
