Some stars may live longer than was thought
The Universe could be a billion years older than was thought, according to Italian and German scientists.
Measurements made in an underground laboratory suggest an atomic reaction that produces energy inside stars is slower than was believed.
It means that estimates of stellar lifetimes are too short. A readjustment gives the Universe an age of 14.7 instead of 13.7 billion years.
The results are to be published in the journal Physics Review Letters.
The new result comes from Luna – the Laboratory for Underground Nuclear Astrophysics – situated underneath Gran Sasso mountain in Italy.
Simulating a piece of the Sun
In Luna, scientists from the Italian Institute of Nuclear Physics and the University of Bochum in Germany are reproducing one of the energy-producing nuclear reactions that take place inside the Sun.
“In an ordinary laboratory on the surface, the effects of the reaction studied by Luna would be hidden by similar, but much more abundant, effects. Because our laboratory is under 1,400m of rock, we have an isolated base to make these delicate measurements,” says Luna co-ordinator Dr Carlo Broggini.
The cycle they are studying – the carbon-nitrogen-oxygen cycle – only supplies a tiny fraction of our Sun’s energy. It is far more important in larger stars.
The result obtained suggests that the carbon-nitrogen-oxygen cycle takes place at half the rate as was believed.
The implications are that massive stars live longer than was first thought, a factor that affects estimates of the age of the Universe based on the ages of the oldest stars.
p.s…..in next article we will view the findings of spiritual scientist or sage put into text thousands of years ago and will compare with findings of modern scientist and will be amazed with the similarity of both findings ….one micro vision and other macro vision and union of two will bring the vision of truth about God….mind of God ….love and purpose of life …..journey of creative enlightenment continues…….be in the journey ….love all.
