Quantum Super-Chilled Helium Structures Might Show Universe’s Early Days

Scientists for the first time in superfluid helium-3 have documented the long-expected occurrence of “walls bound by strings.” The existence of such a material, initially forecasted by cosmology theorists, might assist explain how the cool down of universe took place after the Big Bang. With the new-discovered capability of recreating these structures in the laboratory, earth-based researchers finally have a method to study some of the potential instances more closely that may have occurred in the early universe.

The results, posted in Nature Communications, followed after two consecutive symmetry-breaking stage transitions at Low Temperature Laboratory of Aalto University. Helium remains a liquid at atmospheric pressure even when cooled down to absolute zero, at which all other objects froze down. Not only does helium stay a liquid at absolute zero, but it turns out to be a superfluid at a temperature that is sufficiently low. A superfluid object has basically zero viscosity, which indicates that it must flow forever without loss of energy.

On a related note, researchers at Uppsala University have made a new structure for the Universe—one that might resolve the mystery of dark energy. Their latest article, posted in Physical Review Letters, offers a new structural idea, comprising dark energy, for a universe that runs on an increasing bubble in a different dimension.

We are aware for the last 20 Years that the Universe is increasing at an ever elevating pace. The answer is the “dark energy” that saturates it throughout, forcing it to increase. Knowing the nature of this dark energy is one of the supreme enigmas of basic physics. It has long been expected that string theory will offer the answer. As per string theory, all matter has of vibrating, tiny “stringlike” bodies. The theory also needs there to be more spatial dimensions as compared to the three that are already fraction of daily knowledge.
