š NEW: Measurements of the cosmic microwave background show the observable #universe is geometrically flat, with temperature patterns appearing at the scale flat #space predicts.
That doesn't prove it's infinite ā a small patch of a much larger curved #cosmos would look flat, and a flat universe can still wrap around on itself through #topology. However, astronomers haven't found any signs of such looping.
