Contact: [email protected] “The main charm of this theory lies in its logical completeness,” wrote Albert Einstein in an essay for The London Times in 1919. He wrote it when asked to explain to readers the meaning of his theory of relativity. "If even one single consequence resulting from it turned out to be incorrect, the entire theory would have to be abandoned; introducing any change inevitably entails the destruction of the entire building," he continued. It must be admitted that he has taken a decisive stance on the matter. More than 100 years after the publication of the General Theory of Relativity, scientists are still looking for inaccuracies in its predictions. Einstein's theory of gravity is also compared to its competitors, of which there is no shortage. "There are dozens of alternative theories on the scientific market that explain the nature of gravitational interaction," says relativist Prof. Piotr Jaranowski from the Faculty of Physics at the University of Białystok on Radio Naukowe. The predictions of these theories have been compared for the past 16 years by a team of scientists led by Prof. Michael Kramer from the Max-Planck-Institute for Radio Astronomy in Bonn, Germany. They observed two rapidly rotating pulsars (neutron stars) generating a strong gravitational field around them. Once again, Einstein's theory proved unrivaled. - There has been no convincing observational evidence that would indicate the need to change this theory - the physicist clarifies. Why look for flaws? Why analyze the predictions of the General Theory of Relativity once again? Although all of its predictions come true, this theory has its weaknesses. - There are enormous difficulties in combining it with quantum mechanics - reminds Prof. Jaranowski. But this is not about "refuting Einstein". - Please note that Einstein did not "refute" Newton. All of our engineering is based on Newtonian mechanics, so it is correct. Einstein generalized Newton's theory by taking into account the effects associated with very strong gravitational fields - the physicist explains. - And I think that we will have to speak in a similar way when we replace Einstein's classical theory with another classical theory (i.e. non-quantum - RN footnote), which turns out to be better in those places where Einstein's theory fails, e.g. in describing the interiors of black holes - he assesses. Maybe time travel? And will it be possible to glue the General Theory of Relativity with quantum mechanics? Will it be possible to quantize gravity? - I am an agnostic on this matter - says Prof. Jaranowski. We also talk about whether all solutions to the General Theory of Relativity equations are physical (I mainly pester the professor about whether it is possible to travel in time), whether Prof. Jaranowski has his favorite quantum theory of gravity, about gravitational waves and the fact that most physicists do not know anything about the theory of relativity. I highly recommend it! *** I recorded the conversation in the studio of the University Podcast Center of the University of Białystok thanks to the courtesy of Dorota Sawicka (thank you!).
