Question

question 3 of 25 resources ai tutor expected rotation curve this image shows the expected rotation curve if stars were the only mass in the milky way. observed rotation curve this image shows the observed rotation curve for the milky way. the curve stays well above the expected values. what does this imply about the milky way? the objects used to measure the rotation curve are not part of the milky way. this information implies that there is a large amount of dark matter in the milky way. this illustrates that the technique being used is unreliable.

Explanation:

The observed rotation curve of the Milky - Way shows velocities staying well above expected values at larger distances. This is explained by the presence of dark matter, which provides additional gravitational force. Dark matter does not emit, absorb, or reflect light but has a gravitational effect on visible matter. The objects used to measure the rotation curve are part of the Milky - Way, and the measurement techniques are reliable.

Answer:

This illustrates that there is a large amount of dark matter in the Milky Way.
