Scientists have observed the fifth state of matter in space for the first time, offering unprecedented insight that could help solve some of the quantum universe's most intractable conundrums, research showed Thursday

Bose-Einstein condensates (BECs)—the existence of which was predicted by Albert Einstein and Indian mathematician Satyendra Nath Bose almost a century ago—are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius). At this point, the atoms become a single entity with quantum properties, wherein each particle also functions as a wave of matter. Scientists believe BECs contain vital clues to mysterious phenomena such as dark energy—the unknown energy thought to be behind the Universe's accelerating expansion. But BECs are extremely fragile. The slightest interaction with the external world is enough to warm them past their condensation threshold. Saiba mais...
