The universe is in a long, slow decline to darkness (the stars are going out) - What can we do about it?

The universe is in a long, slow decline to darkness

Sorry folks but it's true, read the article! Here's a much edited-down version:

The universe is cooling down, its stars pumping out about half as much energy as they did 2 billion years ago. From the birth of the first stars, nuclear fusion in their cores has been converting matter into energy"”the energy that makes stars shine. But stars don't shine forever; eventually they run out of fuel and die. Astronomers don't know when the universe's energy output peaked, but, according to the GAMA project, we're well past that point now. Energy output from nearby space is dropping across all of 21 different wavelengths, from ultraviolet to far infrared. The GAMA team says the universe is well advanced on a long, slow decline toward a cold, dark future.

In other words, the stars are going out!

My question

Using either your imagination and soft-science or actual hard-science, can you suggest ways that the human race and/or other sentient life-forms could stop this eventual decline.

Specifically I'm trying to come up with a consensus of the sort of thing we could do to prevent it. No magic but even wild suggestions will be of interest if they make sense.

Narrowing it down

So that it's not just a free-for-all, here's what I'm looking for:

In the far distant future, the human race still exists in some form. I don't know whether we've evolved. I don't know what amazing science we can do. Also there may be other life-forms involved in the endeavour with us or independently.

Here's the crux:

Is it possible in principle that we can stop the extinguishing of the stars and the decline of the universe? Or is it completely impossible? Is there some way we can escape our fate?

Bear in mind that the universe may be infinite and that we can probably only affect a portion of it.

Also bear in mind that other alien races may be trying to do the same thing even if we cannot communicate with them.

Finally throughout history, well-known and knowledgeable people have repeatedly said that something is impossible only to be proved wrong - often in their own lifetime.

SOS! Help us to survive!
