We are not sure exactly how many galaxies are in the universe. There could very possibly be millions or even billions.
Yes, because scientists have found hundreds and hundreds of galaxies already and scientists say that there are more galaxies out there that they haven't found!
at least 100 billion or more.
There are approximately 100 billion galaxies in the known Universe.
No, while we do not know the actual figure best current estimates are that there are around 200 billion observable galaxies.
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.

scientifically speaking, yes
The universe definitely has more than one black hole. Just in our galaxy alone there's an estimated 100 million of them, and the observable universe has at least 100 billion galaxies.
according to Astronomy there are about more than 100 billion galaxies in the observable universe.
You don't. That's way too much. You just get the redshift of a sample of galaxies. As a clarification, the current estimate is about 170 billion galaxies - and that refers to the "observable Universe". The entire Universe is expected to be much larger than that (and have many more galaxies), but those can never be observed.
About 13 billion years old. The Universe itself is approximately 13.75 billion years old. All galaxies are about the same age and Irregular Galaxies were more common when the universe was younger.
