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.
Kornreich used a very rough estimate of 10 trillion galaxies in the universe. Multiplying that by the Milky Way's estimated 100 billion stars results in a large number indeed: 100 octillion stars, or 100,000,000,000,000,000,000,000,000,000 stars, or a 1 with 29 zeros after it.
