#GS3 Science and Technology
University of Bonn scientists have reported a hitherto unknown phase transition in an optical Bose-Einstein condensate called the overdamped phase.

- 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.
- BECs straddle the line between the macroscopic world governed by forces such as gravity and the microscopic plane, ruled by quantum mechanics.
- 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.
- NASA Scientists observed the “fifth state of matter” in space aboard the International Space Station (ISS) for the first time.
