Astronomers in the fourth week of January 2013 revealed that they have made the most precise measurement of the fact that how the Universe has cooled down in a period of 13.77 billion years history following the prediction made in the Big Bang Theory.
To find out the fact and to carry on the study, the astronomers studied molecules in the gas cloud at a distance of 7.2 billion light years from us somewhere in the universe – a distance so far that the light emitted from it took half the age of the Universe to reach us. A team of Astronomers from France, Germany, Sweden and Australia used the Australian Telescope Compact Array to measure the heat of Universe at the time when it was half of its current age.
A statement released from the CSIRO Astronomy and Space Science described that the study has been able to find out the most precise measurement to identify the fact that how the Universe has cooled over a time of 13.77 billion years.
The scientists looked back halfway across the Universe to look back halfway into the Universe history and the basic reason to do so is to identify the time, when the light left the galaxies. Astronomers studied gas at a distance of 7.2 billion light years away in an unnamed galaxy and identified that the cosmic background radiation was the only thing that kept it warm – left over by the big bang. Behind this unnamed galaxy PKS 1830-211 quasar is also in existence.
