Gravitational waves have not shown the presence of extra dimensions
Source:
Although last year's discovery of gravitational waves last year, born of the collision of neutron stars, it was awesome, it added extra dimensions to our understanding of the Universe — literally, anyway.
The Astronomers at the University of Chicago found no evidence of the existence of extra dimensions in the Universe, starting from the gravitational wave data. Their study, published in the Journal of Cosmology and Astroparticle Physics, was one of many that appeared after extraordinary claims by LIGO last year, when the Observatory recorded the collision of neutron stars.
thethe Beginning of gravitational wave astronomy
The first detection of gravitational waves in 2015, for which three physicists won the Nobel prize, was the result of the collision of two black holes. Last year, scientists observed the collision of two neutron stars. The main difference between them is that astronomers were able to observe the effects of neutron stars with traditional telescope, and produced two results that can be compared: one for gravity and one for the electromagnetic (light) waves.
For an explanation of dark matter and dark energy, scientists have proposed a variety of theories, and many alternative theories of General relativity, starting with adding extra dimensions of the Universe, says co-author Maya Fischbach. One theory is that at large distances gravity will "leak" into extra dimensions. Because of this, it will become weaker and will be able to explain the weakness of gravitational forces compared with the other fundamental interactions.
The Discovery of gravitational waves LIGO, recorded on the morning of 17 August 2017, followed by the detection of gamma-rays, x-rays, radio waves, optical and infrared light, allowed to test the theory. If gravity leaks into other dimensions, the signal measured by the detectors of gravitational waves will be weaker than expected. But he was not.
At this point it is obvious that the Universe has all the same familiar dimensions — three spatial and one time — even at the scale of a hundred million light years. But this is only the beginning, scientists say. Theories so much that we even yet tools to all of their iron to confirm or deny.
