An international team of apx. 100 scientists using information garnered from the world's most powerful telescopes - both land and space based - to study the energy emitting from more than 200,000 galaxies, in a wide slice of the observable universe.
The up to date data has confirmed the cosmos is radiating only half as much energy as it was 2 billion years ago.
It really should be pointed out that the universe is an elder statesman at over 13 billion years old. Our sun alone is a third generation star. Vast amounts of energy have to be squeezed into smaller and smaller areas to make star formation possible, hence far fewer stars.
Death is a bit of a misnomer because the universe will still be there, but its stars and all else that produces light and stellar fire will fizzle out.
It will just grow old forever, slowly converting less and less mass into energy as billions of years pass by until eventually, it will become a cold, dark and desolate place, where all of the lights go out,I paraphrased - astronomer Luke Davies.
