Some 13.8 billion years ago, the universe began with a rapid expansion we call the Big Bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn't ...

New techniques for accurate measurements of tiny quantum objects

New research led by a team of scientists at The Australian National University (ANU) has outlined a way to achieve more accurate measurements of microscopic objects using quantum computers—a step that could prove useful ...

A quantum approach to a singularity problem

One of the major issues in general relativity that separates it from other descriptions of the universe, like quantum physics, is the existence of singularities . Singularities are points that when mathematically described ...
