Researchers from the International Centre for Radio Astronomy Research in Western Australia have revealed that universe is heading towards its end. But there is no need to worry as of now as it would take at least 100 billion years before it dies.

The researchers made the claim after measuring the energy generated across 200,000 galaxies more precisely than ever before. They determined that the energy is equivalent to only half of what it was two billion years ago and is continually fading.

In order to perform the task of observing the galaxies and map various types of energy output, scientists put into use seven of the world’s most power telescopes. The energy output ranged from far infrared to the far ultraviolet.

Professor Simon Driver from ICRAR will discuss their findings at the General Assembly of the International Astronomical Union in Honolulu on Tuesday.

“We've got three different indicators – we've got the total energy output, we’ve got rate at which galaxies are merging and we’ve got the star formation rate. All three of those indicators are telling us that the universe is on a steady decline”, said Driver.

The universe has attained the age of 13.8 billion years. Five billion years down the line, the sun will swell up and swallow the earth. It will collide with the nearest major galaxy in about 10 billion years. Universe will be so expanded and producing so little light in about 100 billion years that nothing would be visible.
