In a new research, scientists have revealed that the universe may be approaching a state of "heat death" when all of its stars, planets and other matter will have the same temperature.
According to a report in the Sydney Morning Herald, the research was carried out by Dr Charley Lineweaver and PhD student Chas Egan from the Research School of Astronomy and Astrophysics at Australian National University (ANU).
They measured the amount of the universes stored energy that has been lost - in a process known as entropy - since the Big Bang.
The result was about thirty times higher than other projections indicating there was less left in the universes "gas tank".
"Its a bit like looking at your gas gauge and saying, I thought I had half a gas tank, but I only have a quarter of a tank," said Dr Lineweaver.
"But I cant tell you how many kilometres you can go on that quarter of a tank yet," he added.
Dr Lineweaver said that work was under way to use the higher entropy figures to produce new estimations of how long the universe would continue to be capable of supporting life.
"One complication was the lack of scientific consensus on the "maximum entropy state of the universe" - how much energy was available and therefore how much could be lost," he said.
According to Dr Lineweaver, this issue aside, the universe appeared to be headed towards a state of "heat death" when all of its stars, planets and other matter would reach exactly the same temperature.
