Is there a point in space where if you look at one half of the night sky you would see the light from stars and the other half would be darkness because there are no stars beyond you in the universe?

The universe doesn't have an "edge". It's unbounded, and possibly infinite in size.

The *observable* universe is just the sphere from which light could have reached us in the time since the Big Bang. If you teleported to the edge of the observable universe, you would still see stars and galaxies in all directions. The more distant stars and galaxies would look younger, as they were in the earlier history universe, because their light took longer to reach you. You'd see this from any point in the universe. The universe basically is the same everywhere.

That said, you *could* get this sort of view, if you were sitting outside of a *galaxy*. Almost every object you see in the night sky is a star within our own galaxy. Some are star *clusters* within our galaxy. Some are planets, and the Moon. And there are three galaxies you can see in the sky with the naked eye, but they are faint cloudy objects rather than point-like stars.

So if you sat like 20,000 light years above the disc of the Milky Way, you would see the Milky Way full of stars below you, but you would not see any other stars in the rest of the sky. You might see a few faint cloudy galaxies, but that's it.

So you can get a view that's mostly starless except for a chunk of the sky, but you won't get it at the edge of the universe, because the universe has no edge.
