Question

in the dark quick check
which characteristic is shared by both dark matter and baryonic matter? (1 point)
they both have been directly observed by scientists.
they both interact with each other.
they both are capable of absorbing light.
they both have gravity.

Explanation:

Dark matter has not been directly observed. It does not interact electromagnetically (so it doesn't absorb light in the normal sense) and its interaction with baryonic matter is mainly through gravity. Baryonic matter is the "ordinary" matter we are familiar with and has gravity. Gravity is a property of both as matter has mass and according to general - relativity, mass generates a gravitational field.

Answer:

They both have gravity.
