"[W]hat we see... is that... the radiation from all those distant galaxies is redshifted, and the farther away they appear to be... the more redshifted... [T]he usual interpretation... is that they're going away. ...So that they would be approaching the speed of light ...at about 15 billion s away. About 15 billion light-years away... their radiation would go to zero energy because of redshifting."

John Dobson (amateur astronomer)
John Lowry Dobson (14 September 1915 – 15 January 2014) was an American amateur astronomer and is best known for the Dobsonian telescope, a portable, low-cost Newtonian reflector telescope. He was also known for his efforts to promote awareness of astronomy (and his unorthodox views of physical cosmology) through public lectures including his performances of "sidewalk astronomy". Dobson was also the co-founder of the amateur astronomical group, the San Francisco Sidewalk Astronomers.
