Nothing lasts forever, not even our universe, not the galaxies, the Milky Way, Mars or the human kind. One day the galaxies will turn their lights off and the universe as we know it will be a thing of the past, hopefully not too soon forgotten. According to an optimistic perspective, death should not be the end of it all, but rather the chance to embrace a change. Metamorphosis is necessary, as it brings progress.
The universe is slowly dying and it has been confirmed by one of the most comprehensive assessments ever conducted. The energy output of the nearby universe has been analyzed, assessed and reconsidered, with scientists declaring that it is on a slow pathway to death.
An international team of researchers has embarked on a mission to examine the energy output of more than 200.000 galaxies and together determined that galaxies are producing only half the amount of energy they used to produce two billion years ago.
Conclusions were based on a study which has made use of giant amounts of data collected from no less than seven telescopes. The devices implied were the European Space Agency’s Herschel telescope, the European Southern Observatory’s VISTA and VST telescopes and the Anglo-Australian Telescope in Australia. The research was conducted by Simon Driver, a research professor at the International Centre for Radio Astronomy Research, in Western Australia.
Scientists aimed to map the entire amount of energy generated within a certain volume of space. They measured the galaxies at 21 wavelengths, confirming in detail what has been known since the early 90’s. The universe, as we know it, is finite and it will die somewhere in the future.
All reserves of energy are finite and the entire amount of energy in the universe was produced during the Big Bang. Everything started back 3 billion years ago, when the universe was exploding along with the rapid formation of galaxies and stars which eventually slowed the process down. The pace has seen a constant decrease ever since.
There is no doubt about the fact that the universe is constantly slowing down and the amounts of energy it produces are dramatically smaller, compared with the past.
On the other hand, the expansion of our universe is accelerating, leading to objects moving farther apart from each other. The universe will grow cooler and darker and other galaxies will slowly move too far away to be seen.
