According to the latest measurements made by a group of astronomers, the method used so far to calculate the age of the bracelets is not correct. They have used the VLA (Very Large Array) telescope at the National Science Foundation in the United States to carry out measurements and have discovered that they are much older than what appear pulsars. Astronomers Bryan Gaensler and Dale Frail have studied the pulsar that seemed to be 16,000 years old and new measurements indicate that the pulsar may be between 40,000 and 170,000 years old.

Gaensler and Frail use a pulsar of the constellation of Sagittarius. This star was born from a supernova thousands of years ago and during that time has been moving away from the supernode at fixed speed. Scientists have calculated that speed and calculated the time it would take to get to where the stars are. That time is much greater than was thought. The exhaustive knowledge of the age of Pulsation is very important, especially because in Physics many theories on matter are based on pulsars. Gaensler and Frail believe some of them may be wrong.
