According to current knowledge in Cosmology, it's believed that the universe is expanding, not only that, but due to the forces of Dark Energy (vacuum force), which accounts for more than 3/4 of all of the Mass Energy in the universe, it's expanding and accelerating, outer objects expanding at a faster rate.
The typical example is painting dots on a rubber inflatable balloon. When inflating, the dots start to separate, and the more one blows, the more separated these become.
Well, nice example. However, there are many instances in which entire galaxies have collided with other galaxies. Even our own Milky Way Galaxy is moving at a rate of 300,000 miles per hour in the direction of the Andromeda Galaxy. That's roughly 134 Km/s.
So, what happened to the idea that all objects in the universe are separating from each other, and accelerating at that?
Maybe scientists should stop using analogies to explain complex theories.
I admit it, I am confused. : )
