From the Big Bang to the Big Picture: A New Comprehensive Look at All Objects in the Universe

Researchers from the Australian National University have developed a model that is the most comprehensive view of the history of the universe. The study highlights the change that the universe underwent from the moment of its formation 13.8 billion years ago to its current state, full of objects such as protons, atoms and galaxies

Identifying the mobility of atoms in biological and chemical systems may help in deciphering the structure of the envelope that protects the genetic material of certain viruses, something that may, in the future, allow harming their reproduction
In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

In the background is the structure of a krypton atom in the classical state where 36 electrons are arranged in a kind of shells. The researchers measured the oscillations in the quantum state (front, in pink) on the outside of an ionized krypton atom and the oscillations that cause the atom to move.

In "heavy fermion" materials, free electrons used for electrical conduction react strongly with atoms and sink to low energy levels before re-emerging and continuing on their way. Their slow progress makes them look heavy. Photo by Mohammad Hamidian/Davis Lab
