Our universe is dying, but not for 100bn years

The universe is slowly dying but we have another 100 billion years, according to a new study of 2,00,000 galaxies which found that the energy generated by them is half of what it was two billion years ago.

Researchers from the International Centre for Radio Astronomy Research (ICRAR) in Australia used seven of the world’s most powerful telescopes to observe galaxies at 21 different wavelengths from the far ultraviolet to the far infrared.

The survey data will help scientists better understand how different types of galaxies form. “It’s going to be a slow dwindling process. It’s about 100 billion years or so until all starlight stops being produced,” ICRAR professor Simon Driver. “The universe has basically plonked itself down on the sofa, pulled up a blanket and is about to nod off for an eternal doze,” he added.
