Supermassive black holes in the depths of space were used for the first time to measure the growth of the universe, resulting in fascinating results.
Astronomers found that the universe seems to expand faster than previously thought, a discovery that suggests a whole. A new set of rules is needed to understand the cosmos.
The speed of expansion of the universe is known as the Hubble constant, named after the American astronomer, who also gave his name to the famous Space Telescope.

It has proven to be a difficult value because the cosmos has been growing ever since the Big Bang. However, the rate seems to vary depending on where astronomers look like and how they measure it
In a new study published in the journal Nature Astronomy scientists used black holes at the center of distant galaxies. as reference points at which the growth rate can be measured.
These bodies are constantly donating radiation and placing it among the brightest points in the universe.
"Black holes are the universe's brightest persistent sources, allowing us to measure the rate of expansion at a very early stage," said Dr. Elisabeta Lusso of Durham University.
He uses data from 1,600 supermassive black holes, as the universe expands and moves apart, the scientists were able to grasp the speed of this expansion.
Earlier experiments used the light generated by the explosion of supernovae measuring the growth of the universe Such measurements could only go back in time.
The glowing black holes allowed Dr. Lusso and her colleague Dr. Guido Risaliti to look further, providing a clearer picture of the early expansion of the universe.
19659172] The discrepancy they found was consistent with the contradictory results which had previously been achieved by the European Space Agency and NASA.
These results suggest that the early expansion of the Universe is different from that predicted by the Standard Model of Cosmology, which describes the age, history, and content of the Universe.
According to Dr. Luso, this could be an explanation for the mysterious force known as dark energy – a theoretical form that occupies most of the universe and accounts for much of its energy.
"We may need to explore new physics, such as the potential properties of dark energy," she said.
Dr. Risaliti of the Università degli Studi di Firenze said that when this dark energy develops – with increasing density over time – this could be an explanation for its results.
"However, this is just one of the many models – all including the new physics – proposed by the theoreticians, and much more work is needed to find a unique solution," he said.
