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

the big freeze

the big crunch

the big rip
