It is not possible to list all designations and redshifts of all 100 billion galaxies (cseligman.com/text/atlas/pgc00.htm)
No, because it will be impossible for astronomers to get all 100 billion redshifts for all 100 billion galaxies in the observable universe.
No. We do not have time to make so many measurements.
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the 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.
There are an estimated 1011 (100 billion) galaxies in the observable Universe. It is not known how much bigger the Universe is, compared to the observable part.
It highly likely that astronomers will name all the designations of the 100 billion galaxies in the universe in this lifetime.
WikiSky will not map all 100 billion galaxies in the observable universe
Yes. To image, catalog, and calculate the redshift of each galaxy individually would take an extremely long time. In order to complete the work in 100 years we would need to measure redshifts at a rate of more than 30 galaxies per second.
Astronomers can name all the designations of the 100 billion galaxies in the universe using their mass, age, and metallicity.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
The observable Universe has somewhere around 1011 galaxies. The entire Universe is much larger than the observable Universe, but currently, it is not known exactly how much larger. It might be infinite in size, but in any case, it is estimated that the Universe is a lot larger than the observable Universe.
No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.
