NO

Space between galaxies is likely very similar space within the galaxies, just with lower matter density. 

For such a theory, you would have to invent a new type of liquid that did not behave gravitationally like normal matter.  Also, keep in mind that galaxies tend to be disk shaped, not sphere shaped.

Liquids, as we know them, also diffract different wavelengths of light at different angles, and thus we would see a rainbow of colors as the starlight would arrive at Earth.

In some ways precisely the opposite is true.  The universe consists of vast "bubbles" of empty space containing very little material with strings and knots of galaxies in clusters.

Sounds like chocolate to me!

I think its no coincidence that so many choc bars have astronomical names - Mars, Galaxy, Milky Way, Uranus, well maybe not Uranus. There's obviously an undercurrent of subversion going on between confectioners and astrophysicists.

Maybe it's because that and coffee are the only thing that keep the Astronomers up at night, Starbucks for example!!
