Final answer:
In a shrinking universe, galaxies would be moving closer together due to the gravitational pull.
Step-by-step explanation:
In a shrinking universe, if you measured the velocities of many galaxies, you would find that the galaxies are moving closer together. Since the universe is shrinking, the gravitational pull between galaxies would cause them to attract each other and eventually collide.
The concept can be illustrated with a simple analogy. Imagine a giant ball made up of a thousand galaxies. Initially, if the galaxies were stationary, they would start moving towards each other due to gravity. To avoid collapsing, they would need to move away from each other at high speeds.
In summary, in a shrinking universe, the measured velocities of galaxies would show that they are moving closer together under the influence of gravity
