If you could peek outside the universe to see what it looks like, what would you see?Credit: Illustration: Karl Tate, based on a photo of Galaxy M74 (NASA, ESA, and Hubble Heritage Collaboration) and the engraving "Awakening of the Pilgrim" from "The Atmosphere: Popular Meteorology" by Camille Flammarion, 1888 If you could somehow manage to step outside of the universe, what would it look like?

The shape of the universe depends on its density. If the density is more than the critical density, the universe is closed and curves like a sphere 🔄; if less, it will curve like a saddle ↩️. But if the actual density of the universe is equal to the critical density, as scientists think it is, then it will extend forever like a flat piece of paper ↔️.

Measurements indicate that the universe is flat, suggesting that it is also infinite in size. 💫
