The coldest known place in the Universe is on Earth!
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.
