It is not visible to the human eye, but it serves as a primary fossil…- The universe measures flat, yet it could still loop back on itselfDraw a giant triangle across space and add up its angles. Measurements so far say they total 180 degrees, meaning space is flat to within a fraction of a percent. That settles the…
The universe might be a single, unified quantum objectWe usually think of the universe as a collection of separate parts—atoms, stars, and people. But new perspectives in quantum mechanics suggest we might be looking at it backward. …
