There is no correct answer as most are not discovered
Nothing...or dark matter.Only 0.03% of our universe are the stars,the planets,the galaxies...99.97% of the universe is nothing...
WikiSky will be unable to map all the 100 billion galaxies in the universe considering that there are most likely more than 100 billion galaxies.

Although we can't calculate the exact no galaxies in the universe , because of the vast distance the universe is spread over, The most accepted assumptions holds that there are approximately 100 Billion galaxies in the universe.
Spiral and Elliptical
Most galaxies move away from us - the farther they are from us, the faster they move away from us. This means that the Universe is expanding.
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

Perhaps you are confusing Universe with galaxy. Most galaxies have a black hole in their center. The Universe has no such thing as a center.
Most of the universe is made up of hydrogen gas, followed by helium. These two gases are the most abundant elements in the universe and can be found in stars, galaxies, and interstellar space.
