Universe slowly dying 'like an old person on the sofa'

such a putrid song

Gee I really like your

Tits

I'd say anything that

Fits

We carry our women

Where ever we go

If you keep your mouth shut

They're gonna know

We're all gonna die

So let's get high

We're all gonna die

So let's be nice

.. Beautiful song.

I have news for you, we are all slowly dying.

Yes, but we tend to be recirculated.

Most depressing thing I read today:

The Universe is slowly dying, thanks in part to a dramatic decrease in the formation of new stars.

There are many theories dictating exactly how the Universe will meet its end, but one thing has been agreed upon: its energy levels are plummeting. Just how rapidly that energy loss has been occurring, had been unclear.

But a massive study of more than 220,000 galaxies carried out by the International Centre for Radio Astronomy Research (ICRAR) in Western Australia has found that the energy emanating from those systems is just half what it was two billion years ago.

"The Universe is fated to decline from here on in, like an old age that lasts forever. The Universe has basically plonked itself down on the sofa, pulled up a blanket and is about to nod off for an eternal doze," said ICRAR professor Simon Driver, who heads up the Galaxy and Mass Assembly (GAMA) project that made the discovery.

GAMA is a massive multi-wavelength survey conducted by honing seven telescopes -- including the European Space Agency's Herschel Space Observatory -- on the mapped galaxies at 21 different wavelengths, from the far ultraviolet to the far infrared.

The team applied "spectral energy distribution analysis codes" to work out things like stellar mass, dust mass, opacity, dust temperature and star-formation rates. This was a vital part of working out energy decline, since stars emit light by converting mass into energy.

As Driver explained: "While most of the energy sloshing around was created in the aftermath of the Big Bang, additional energy is constantly being released by stars as they fuse elements like hydrogen and helium together.

"This newly released energy is either absorbed by dust as it travels through the host galaxy, or escapes into intergalactic space and travels until it hits something such as another star, planet, or very occasionally a telescope mirror."

In a paper announcing the find, the GAMA team also listed "supernovae, winds, and other mass-loss processes leading to metal enrichment, dust formation, and the heating of the interstellar medium through shocks and other turbulent processes" as other ways stars are responsible for leaking energy into the Universe.

There is plenty of literature to suggest the birth rate of new stars peaked eight billions years ago -- but the latest findings demonstrate just how much that steep decline has impacted the overall energy output of the Universe.

The paper concludes: "This [energy] decline is significant despite the cosmic variance uncertainty, and in line with our understanding of the evolution in the cosmic star formation history, which shows a decline of a factor of approximately ×1.5 over this time-frame."

The work is described as the "largest multi-facility dataset ever assembled", but the team is not content. It wants to map the energy production of the Universe's entire history, and plans to do so by harnessing the power of the not-yet complete Square Kilometre Array (which you can read all about on WIRED here).

If the slow death of the Universe is all a bit much for you, forget what you've just read and click play on the video above -- a nice 3D fly-through of the mapped Universe that will leave you in a contented trance.

Bummer.

Question.

Why can't the universe's slow death be viewed like that of a newborn baby?

Because a newborn baby brings the promise of a future, of new lives, of narration, of possibilities; while a universe that just expands and dies brings no such thing. All that lies in that future is just cold emptiness...

I know that energy isn't infinite, but who says the universe isn't an infant?

With it's expansions, who knows? Maybe it has in it, the soup to make E.T. or Aliens or perhaps we will be part of that space soup and who knows? May even be Borg.. We just don't know in the expansion what can come and if that mindless energy just disappears, then who knows what's out there eminanting it's own cosmic energy - it's own independent universe..

We just don't know.

Well, from some supreme/fifth-dimensional being's point of view, the universe is already dead, currently in existence, and still not born all at the same time.

Even fleas flee the dead cat.

What if, it's alive but...

That supreme thing you refer to, is just a law of physics? - in which; It has to die.

But there's probably nothing outside observing it atm able to see it's death and able to see it's birth...

That record theory of predestiny could be a load of hoo-ha.
