For IAG astrophysicist Rodrigo Nemmen, the area still has many discoveries to make to clarify the mysteries of the universe. In February this year, American researchers from the LIGO project (acronym in English for Laser Interferometer Gravitational-Wave Observatory ) observed a series of “distortions in space and time” caused by a pair of black holes with solar masses in the process of merging. These distortions, known in physics as “gravitational waves”, confirmed predictions made by Albert Einstein in his Theory of Relativity. In the editorial that informed readers about the discovery, writers from the English newspaper The Guardian asked themselves whether the new finding advocated the “end of physics as we know it”. For astrophysicist and professor at the Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG) at USP, Rodrigo Nemmen, it is precisely the opposite: “I would say it is the beginning and what is most exciting is what is to come.
In the astrophysicist's opinion, the importance of the discovery is multiple. “This is something that we have been waiting years to observe”, celebrates the researcher, evoking the set of scientific theories published by Einstein in Steps to discovery It is worth noting, as Nemmen explains, that there was already an indirect observation of gravitational waves. And this earned a Nobel Prize for rese Whatsapp Number List rchers Russell A. Hulse and Joseph H. Taylor Jr., who received the prize in for discovering a new type of pulsar, opening up new possibilities in the study of gravitation. “They discovered a binary system, made up of two pulsars – neutron stars – that revolve around each other”, says the professor. It was by observing the radiation coming from this system that both noticed an increasing proximity between the stars. “It’s a ballet that’s getting more and more intimate,” he illustrates. The only way to explain the behavior, he clarifies, would be if this binary system.
Was emitting gravitational waves. “In physics, we know that if an orbit is getting closer, that system is losing energy – and the way it loses energy is through gravitational waves,” he explains. The comparison of this orbit matched Einstein's theory perfectly. Now we not only see the light of the universe, we also hear the symphony of space/time Astrophysicist and professor at the Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG) at USP, Rodrigo Nemmen - Photo: Disclosure Astrophysicist and professor at the Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG) at USP, Rodrigo Nemmen | Photo: Disclosure Just over thirty years after this first step towards proving the phenomenon, scientists celebrate the detection made in the USA. “This observation is a historic moment in science and, in particular, in astronomy, because it marks the beginning of a revolution in the field”, declares the professor. Until now, astronomy depended on observing the light.
