Portsmouth university researchers started a new measure of one of the most controversial themes of cosmology.

The three cosmology of the Institute of Cosmology and Gravitation analyzes new data to ensure one of the most accurate measurements of Hubble Constant.

Hubble Constant has long and disputed history with known conflicts between astronomers, and people still continue to value its value for almost centuries.

Hubble Constant is the local expansion index of the universe and is the cornerstone of modern cosmology. This expansion is first measured by Edwin Hubble in 1929 and is known as the Habel Law. The principal part of this law is the Habliss Constant, which represents the exact expansion index (ie, how fast our local cosmic neighborhood develops).

To get a new measurement, ICG researchers used a new methodology, "Climbing the Middle Distance" method, adding new cosmological results to the face Ia supernova using Dark Energy Survey (DES), using distance distance measurements.

Professor Bob Nicol, Pro Vice-Chancellor of Research and Innovation and co-author of co-research, said: "Using these new data and new methodologies is one of the most accurate measurements of this permanent date.

"Our value agrees with a lot of difference, but I disagree with the Nobel Prize that Astronom has earned by Adam Rice and his team, which led us to some tension or maybe telling us that we do not understand that our local world is fascinating."

The study is one of eight new works from DES, which presented a special DES meeting in London's Royal Astronomical Society on November 9.
