Using data gathered from more than 200,000 galaxies, astronomers have been able to measure the slow decline in the universe’s energy output since the Big Bang.

The fact that the Universe is slowly fading has been known since the late 1990s, but this work shows that it is happening across all wavelengths from the ultraviolet to the infrared, representing the most comprehensive assessment of the energy output of the nearby Universe. “The Universe will decline from here on in, sliding gently into 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,” concludes Simon Driver.

I wish to note the significant uncertainty of this result. While this result is important and does strongly suggest that the universe is dying, 200,000 galaxies is hardly a significant representation of the universe’s galaxy population.

    How is our government addressing this threat to our security?

    (most extreme sarcasm)

    Global warming compared to universal cooling… Our problems don’t seem so bad after all.
    But then a sample group of 200,000 out of billions of billions of galaxies don’t seem hardly enough to do an accurate comparison.
    In our oscillation in the spiral arm of the Milky Way galaxy, we occasionally go through gas clouds that obscure distant stars.
    If the stars start to wink out and a big dark area appears in the direction of our travel… prepare for another Ice Age as the Interstellar gases envelops our solar system. (just like Noah’s flood, but the flood was frozen water, not liquid)
    Sorry, got carried away…

    My greatest fear is proton decay.
