Based on current evidence, decide whether each of the following statements apply to the concept of dark matter, dark energy, both, or neither. Drag each statement into the appropriate bin.
Dark Matter Only:
as mass.
most common form of mass in the halo of the Milky Way Galaxy.
detected through its gravitational attraction.
likely to consist of tiny, weakly interacting particles.
Dark Energy Only:
inferred to exist from the measured acceleration of the universe's expansion.
the proposed source of a universal repulsive force.
Both Dark Matter and Dark Energy:
the universe contains more of this than it contains matter made from atoms.
we do not know what it is made of.
Neither Dark Matter nor Dark Energy
blocks light from stars behind it.
"dark" because it emits only infrared light.
