The universe is cooling down

Astronomers use telescopes in Australia to measure the temperature of the universe, and draw conclusions that it is cooling like predicted by experts according to the Big Bang theory.

A group of international experts from Sweden, France, Germany and Australia used the Australian Telescope Block Network in New South Wales to measure the temperature of the universe when it was only half the current age.

'This is the most accurate measurement ever made about the cooling of the universe during 13.77 billion years of its history' , according to Space.com quoted Robert Braun of the Scientific and Public Research Organization. Federation of Australian businesses.

Astronomers have looked at the light moving half the length of the universe, which means that the light begins the journey toward Earth when the universe is only 50% of its current age.

They studied the gas at the time of the universe 7.2 billion light-years ago, only warmed by the cosmic background radiation, the heat remaining from the Big Bang event.

The Big Bang theory of cosmic formation suggests that the background radiation temperature of the universe will gradually decrease as the universe expands.

And that's what experts have observed, according to chief researcher Sebastien Muller of Chalmers University of Technology (Sweden).

'The universe was several billion years ago a few degrees warmer than it is now, just like the Big Bang theory predicted , ' according to Muller.
