imagine an empty space without bars.

you're contradicting yourself. empty space means empty space, no universe. Universe is a presence of matter.

I don't know about the "bars", but I like to use a snow globe as an example. Whatever you do, the snow always eventually ends up in the bottom of the globe, because of gravity. But the gravity, Earth's gravity, is OUTSIDE the snow globe. If you removed the gravity, like on the space station, in orbit, the snow would never settle, just keep floating around with the currents in the globe. That's how the universe works. There's no outside gravity to pull anything "down", so nothing settles to the "bottom" of the universe.

The universe is not kept in a rigidly fixed state but the planets keep moving in a similar way by virtue of inertia, momentum and gravity. There is nothing holding it up or down (which is up anyway?) but if you ever got to the edge of the universe, I'm sure there would be a few bars there being run by expats. It's always the case.

Without bars? As in, no place to get a drink in space?
The Universe stays up because it is expanding from the Big Bang. If it stopped expanding, it would fall back in a Big Crunch.

Gravity is what keeps the planets, moons, stars and galaxies where they are. The Moon orbits the Earth because of the gravitational attraction between the two. The Earth and all the other solar system objects orbit the Sun because ofthe gravitational attraction between them. The Sun and all the other stars orbit the centre of the galaxy -again because of gravity.

Space isn't empty! It is made up of what is known as "Dark Matter". Recently we have a sketch from one of our satellites showing the construction of this dark matter. This is what holds the universe together.

Space isn't empty, it has vast amounts of materials. And it all acts on the rest through gravitational forces.

It's only empty to the naked eye. Even with telescopes and electron microscopes, we surely don't know everything that space is made up of.

It doesn't, everything in the universe is floating around in space, you could call it falling, what's the difference.

well, if you get this REALLY big compressor, you could compress the universe into as small as you wanted too. you could, alternately, induce a gigantic black hole in the center of the univers adn then it would serve the same purpose.
