Cordovan who participated in taking the first image of a black hole

Wednesday, a scientific event was revealed around the world: the first image of a black hole.

The European European Observatory (ESO) and the synchronized system of the Event Horizon Telescope Team (EHT) showed the image taken in the M87 galaxy, 58 million light-years away, involving 8 space telescopes from the planet and 200 scientists 60 prestigious institutions of the world. A Cordouan was one of them.

It is about Luis Lehner, a graduate researcher from the Faculty of Mathematics, Astronomy, Physics and Computer Science (FaMAF) of the National University of Córdoba (UNC), is currently working at the Perimeter Institute of Theoretical Physics of Canada, where he has resided for 25 years. years.

His job was to lead several students involved in the integral part of creating the models in order to get that first picture of a black hole.

After this discovery, "the next step is to better understand the black holes and to try to understand the limits of Albert Einstein's theory of gravity, which remains a useful theory for describing these extreme gravitational extremes. find differences with Einstein's theory, we can develop a new theory to replace it, "said Cordovan.

In dialogue with Cbad 10 He explained that "a black hole is a prediction of Einstein's theory that if we take a region of space-time so tense that it produces such a gravity, it prevents any element from escaping, not even the light can go out, which is why it looks black.His gravitational pulling exceeds the limits that we could imagine as than human beings. "

He illustrated that what happens in the black hole is identical to what happens in a bath when we remove the cap. "This vortex, in this case this gas, which is close to the black hole, is gradually starting to fall and its approach is accelerating, warming up and increasing the emission of electromagnetic energy."

Lehner and other experts attended a roundtable on the announcement of the collaboration between the Horizon Einstein telescope and the Horizon telescope, as part of the eighth international GRAV19 conference that was held on Plaza Cielo y Tierra, in Córdoba.
