The sky over Chile allowed, with its special natural conditions and the contribution of European telescopes, to reconquer Albert Einstein, with a new confirmation of the validity of his Theory General of Relativity formulated by the genius more than a century ago
The European Observatory of Space (ESO) reports today the new validation of the theory of the German theoretical physicist, who predicts that objects deform the space-time that surrounds them, causing the deviation of the light that pbades.
In this case, the ESO and his Very Large Telescope (VLT) of northern Chile were able to check for the first time the effects Einstein tried his theory with respect to the motion of a star near A supermbadive black hole.
ESO astronomers were able to follow the movement of the S2 star when it pbaded last May to less than 20,000 million kilometers from the hole and moving at a speed of 39, a little more than 25 million kilometers per hour.
To follow this star, they used infrared observations taken with Gravity, Sinfoni and Naco instruments, located in the Very Large Telescope. (VLT) in northern Chile, ESO explains
They then compared the data obtained by Gravity and Sinfoni on the speed and position of the star, with earlier observations made with other instruments , with the predictions of Newton. , general theory and others on gravity.
"The new results are incompatible with Newtonian predictions and agree in excellent manner with the predictions of the General Theory of Relativity", according to the ESO .
New measurements demonstrate an effect known as gravitational redshift, considered a measure of the expansion of Unive
"The star's light is stretched to longer wavelengths by the very strong gravitational field of the black hole.And the change in the wavelength of the light of S2 concords precisely with what Einstein predicted in his theory of General Relativity, " added ESO.
Observatory officials pointed out that "this is the first time, this deviation from the Newtonian gravitational theory simpler was observed, compared to the movement of a star near a supermbadive black hole. "
" More than a hundred years since he published his article on the budgets of general relativity, it has been demonstrated once again that Einstein was right, in a much more extreme laboratory than he could have imagined " ESO claimed.
Françoise Delplancke, Head of Engineering Department The ESO systems have stated about this scientific breakthrough that "in the solar system, we can only test the laws of physics now and in some circumstances, therefore, in astronomy, it is very important to check that these laws are equally valid where the gravitational fields are much stronger. "
The ESO revealed last July that the theory of Einstein is also valid in galaxies located beyond the Milky Way.
In the published study, the galaxy ESO 325-G004 was used, which acts as a strong gravitational lens, distorting light from a distant galaxy behind and creating a ring. By comparing the mbad of ESO 325-G004 with the curvature of the space that surrounds it, astronomers have discovered that gravity at these scales of astronomical distance behaves as predicted by general relativity . 19659003] Then, at the beginning of that same July, the validation at Einstein came from the observations of a group of astronomers, who found a new demonstration in the constellation Taurus, at 4,200 light-years from the Earth
The measurements were used to demonstrate in this case the applicability of the principle of equivalence, founder of the theory of Einstein, to bodies having their own gravitational field. EFE
