How do we know that the universe is flat

WebAug 11, 2024 · Measurements taken by satellites have pointed to the universe having a flat geometry. In a flat universe, two light beams shot side by side through space will stay parallel forever, and will never cross or drift apart. In this sense, we can still think of a cylinder or torus (donut) shaped universe as being “flat”. WebThe Sun is now a microscopic speck of dust, as are its nine planets, whose orbits are represented by the flat disc of the coin. How far away is the nearest star to our sun?
