Italian and German scientists have been studying a particular form of nuclear reaction that takes place inside stars. By taking their measurements under 1,400 meters of rock, they have ascertained that the carbon-nitrogen-oxygen cycle (significant in more massive stars than our Sun) takes twice as long as previously believed.
The new information suggests that the more massive stars live longer than was first thought, and this has a significant effect on estimates for the age of the Cosmos. The age of the Universe is now theorized to have increased from 13.7 to 14.7 billion years.
