The size and shape of Laniakea depend on the rate of cosmic expansion, which is described by the hubble parameter.
Allard K. Lowenstein was so far to the left of WFB that WFB wouldn't have been able to find him with the hubble telescope.
Williams did it with me several times, for instance when I mentioned the hubble Space Telescope.
space telescope placed in orbit 1990, named for U.S. astronomer Edwin P. Hubble (1889-1953).
American astronomer who demonstrated that there are galaxies beyond our own and that they are receding from ours, providing strong evidence that the universe is expanding. Hubble also established the first measurements for the age and radius of the known universe, and his methods for determining them remain in use today.
