It is possible that someday astronomers have all J2000 coordinates of 100 billion galaxies in the observable universe.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
No, because it will be impossible for astronomers to make an astronomical catalog that lists B1950 and J2000 equatorial coordinates and cross-identifications for all 100 billion galaxies in the observable universe.
No. Because it will be impossible for astronomers to make an atlas of at least 100 billion galaxies in the observable universe.
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.
Someday astronomers may have classified all the shapes of 100 billion galaxies in the observable universe.
Maybe someday in the future astronomers will get all the J2000 coordinates of the 100 billion galaxies in the universe.
No, because it will be impossible for astronomers to make a 3D panoramic view of all 100 billion galaxies in the observable universe.
No, because it will be impossible for astronomers to get all 100 billion redshifts for all 100 billion galaxies in the observable universe.
No, because it will be impossible for astronomers to survey at least 100 billion galaxies (each with 100 billion stars) to make a 3D map of the observable universe.
No. We do not have time to make so many measurements.
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.
WikiSky will not map all 100 billion galaxies in the observable universe
