Astrophysicists can measure the growth rate of the universe. Or call "Hubble Constant" the last time this year. Knowing that our universe grew more rapidly than ever. Experts have reviewed the current physics principles because they did not explain the phenomenon

A team of researchers led by Adam Rees of Hubble Johns Hopkins reported the latest results of measuring Hubble's latest results. Hubble Space Telescope has used these values ​​to be more accurate than before being able to measure these values. Thus, there are only a hundred thousand errors.

The group of Rees group used the Cepheid variable in the group of stars of the great Magellan Cloud. The principle of calculating the distance and calculating the growth rate of the universe is this time in this moment, according to stars that transform the sun into a bright brighter than a candle. Standard candle or the lighthouse of the universe Astronomers use clear lights and gestures at their precise frequencies as a primary measure Calculating the distance in space

The results show that the Universe is growing with a new rate of acceleration of 74.03 kilometers per second per MegaParsec. This means that the world looks at 3.26 million years of global light at a distance of 74.03 kilometers per second.

Star clusters in the Magallans Cloud Great What is the Nano galaxy and the Milky Way as the galaxy is a changing star of the sky as a measure of distance from the universe.

These numbers increase the same research team for the measurement and calculation of last year, which is 73.5 kilometers per MegaParsec per second. Scientists believe that this situation is calculated using the cosmic deep microwave (CMB) data, rising to 9% with the original Constant Hubble. The onset of the universe, after the Big Bang, about 380,000 years ago

Rees, the Nobel Prize in Physics in 2011, says "at the beginning of the universe, a constant Hubble, that is," with the ultimate constant Hubble in Conflict Say new issues in the most exciting cosmology decades. The difference between these two numbers is likely to increase every time. The measurement did not happen until it reached the point of accident or error

Rees has stressed that this phenomenon is the result of dark energy, which accounts for 70% of all the materials and energy in the universe. This dark energy can have a different behavior than to understand. For example, matter may be more intense or darker in interacting with normal matter than before. All of these affect the growth rate of the universe significantly

"We have cosmological models You can not explain yet for physical approach, which can connect two different sets of data together twice," said Rees.
