Here’s what you’ll learn when you read this story:Scientists are relatively certain that the observable universe is relatively flat, but in terms of the cosmos’s global topography, uncertainty reigns. When it comes to local geometry, scientists are relatively certain that the observable universe is flat—or, at least nearly flat. “Much more can be done to discover, or constrain, the topology of space.”Exploring this global topology is crucial to understanding the universe. Eventually, stating that we live in one topological universe as opposed to another will require some sort of observational evidence. So, the team said it’s now looking into ways to discover a kind of “topological fingerprint” in CMB data to support certain theories.
