Odd I stumbled on to this site obviously from a google search how long does vic w/d last and felt compelled to read every post. I am sitting here at the 24 hour mark and its not dreadful but it is pretty bad.
The best estimate from a 1999 study set that number at about 125 billion galaxies, but a 2013 study - after the Hubble Space Telescope was upgraded considerably - indicated that there are 225 billion galaxies in the observable universe.
Livio pointed out there could be galaxies in these other universes â if they exist â but we have no way right now of knowing for sure. So the number of galaxies could even be greater than 200 billion, when considering other universes. In our own cosmos, Livio said, astronomers will be better able to refine the number upon the launch of the James Webb Space Telescope (for which his institute will manage the mission operations and science).
