Photograph ... WebWhen the Hubble Space Telescope was launched, the uncertainly over the universe’s expansion rate was off by a factor of two. This meant that the universe could be as young as 9.7 billion years or as old as 19.5 billion years. The younger value presented a huge problem; it would mean the universe was younger than the oldest known stars. Expand …
