Einstein's general theory of relativity continuesconfirmed by modern observations. Astronomers from Australia have discovered one of the most effective evidence of one of the elements of the theory of relativity by observing a pair of high-density stars that twist and twist the space-time continuum.
For 20 years, twospace bodies with superhigh mass and density. In this case, the CSIRO Parkes telescope was used, which helped to obtain another confirmation of the theoretical research of the ingenious Einstein.
Monitoring was carried out for the PSR J1141-6545 system,consisting of two dead "stars rotating relative to each other. One of the objects is a white dwarf about the size of the Earth, but with a density 300,000 times larger than our planet. The second object is a pulsar, containing 100 billion earth masses, but having a diameter of only 20 km (12.4 miles). The pulsar rotates around a white dwarf with a period of five hours, while both objects rotate very quickly around their own axis.
Space-time continuum according toEinstein’s assumption is bent next to objects that have gigantic masses. The mathematical theory of Joseph Lens and Hans Thirring in combination with the Einstein hypothesis suggests that rotating massive bodies also provide a curvature of the space and time system.
Previously, scientists found that a pulsar emitsat regular intervals. However, for a couple in the PSR J1141-6545 system, which was monitored for 20 years, scientists discovered a shift in the radiation signal, indicating a change in the inclination of the white dwarf orbit.
This phenomenon is explained by the fact that rotating space objects twist and attract the space-time system in the vicinity, which is consistent with Einstein's theory of relativity.
