Scientists knew since the late 90s that the universe is undergoing a slow and silent death, but a new research claims that it has the evidence.
A recently published study in the Monthly Notices of the Royal Astronomical Society shows that the universe releases half the energy it used to during its early days. Scientists explained that that is a clear sign that the universe is slowly fading away.
Study authors also found that the rate at which new stars are born is slower than the rate at which they cool down or explode. This means that more and more star lights will be switched off and no young stars will replace them. In the end the cosmic light show will end up in the darkest of nights.
During their study titled the Galaxy and Mass Assembly (GAMA), researchers surveyed more than 200,000 galaxies and the energy they produced in 21 different wavelengths. Each and every wavelength type of image showed that the Universe is closing its eternal doze.
Scientists used seven state-of-the-art telescopes located on ground and in space. Telescope imagery showed that the galactic energy input is now lower than it was when the Universe was created. The team explained that the main cause is the low rate at which new stars emerge. That rate is so slow that we can physically observe its consequences through the galactic energy output.
The data analyzed during the survey was gathered over the course of seven years. Scientists plan to use that data to conduct other studies on the nature of the universe and grant their peer researchers full access to the database for scientific purposes.
But the Universe’s demise is not a cheering piece of news to read while sipping your morning coffee. Scientists reassured us however that the scenario may not happen earlier than 100 billion years.
The research team explained that star formation reached its peak a long time ago when it entered a steady decline. The recent data only provided some snapshots on the situation.
After some calculations researchers drew the conclusion that the total energy output of the galaxies surveyed plunged 40 percent from the universe’s beginnings. The team also suggested that the universe already entered a perpetual old age.
“The Universe has basically sat down on the sofa, pulled up a blanket and is about to nod off for an eternal doze,”
said Prof Simon Driver, senior investigator for GAMA project.
