WHAT SHAPE IS THE UNIVERSE?�MATCH THE THEORY TO THE CORRECT DESCRIPTION AND DIAGRAM
Theory | Diagram | Description |
| | if the universe contains the right amount of mass, has no bounds, and expands forever, slowing but never stopping |
| | if the universe contains enough extra mass to stop expansion, but will slowly collapse back in on itself |
| | if the universe doesn’t contain enough mass and continues on forever without stopping |
negative curvature
flat universe
closed universe/ positive curvature
HOW WILL THE UNIVERSE END?�MATCH THE THEORY TO THE CORRECT DESCRIPTION
Theory | Description |
| the Universe would, in theory, become so vast that supplies of gas would be spread so thin that no new stars can form |
| the expansion of the universe eventually reverses and the universe re-collapses |
| the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe |
