Although last year's discovery of gravitational waves inlast year, born of a collision of neutron stars, was amazing, it did not add unnecessary dimensions to our understanding of the universe - literal, in any case.
University of Chicago astronomers not foundno evidence of the existence of additional dimensions in the universe, based on gravitational-wave data. Their study, published in the Journal of Cosmology and Astroparticle Physics, was one of many that emerged from LIGO's extraordinary statement last year when the observatory recorded a collision of neutron stars.
The beginning of gravitational wave astronomy
The very first detection of gravitational waves in2015, for which three physicists received the Nobel Prize, was the result of a collision of two black holes. Last year, scientists observed a collision of two neutron stars. The main difference between them is that astronomers could observe the effects of neutron stars using a traditional telescope and produced two results that could be compared: one for gravitational and the second for electromagnetic (light) waves.
To explain dark matter and dark energyscientists have proposed a variety of theories, and many alternative general theory of theories that begin with the addition of the universe to additional dimensions, says co-author Maya Fischbach. One theory is that gravity will “leak” into extra dimensions at large distances. Because of this, it will become weaker and will be able to explain the general weakness of the gravitational force in comparison with other fundamental interactions.
Discovery of gravitational waves LIGO,recorded on the morning of August 17, 2017, followed by the detection of gamma rays, x-rays, radio waves, optical and infrared light, allowed us to verify this theory. If gravity flows into other dimensions, the signal measured by the gravitational wave detectors will be weaker than expected. But he was not.
At the moment, it’s obvious that the universe has allthe dimensions we are familiar with - three spatial and one temporal - even on the scale of one hundred million light years. But this is only the beginning, scientists say. There are so many theories that we don’t even have the tools to refute or confirm all their hardware.
