The sun will swallow the earth

Reported here:

According to experts from the Galaxy And Mass Assembly (GAMA), the universe is only churning out half as much energy as it did 2 billion years ago, and is gradually approaching a state of entropy. The study confirmed something researchers have suspected for decades: the stars that populate countless galaxies are slowly burning themselves out. ...

The study, which was jointly led by Simon Driver and Andrew Hopkins, was an international effort that harnessed technology both on land and in space to study 200,000 galaxies and the energy they generated. Basically, it found that stars have lost roughly half their firepower over the last 2 billion years. ...

There is one type of cosmic body largely responsible for emitting galactic energy, and it's slowly losing steam, experts said. "Those emissions are dominated by stars," said Adam Burrows, professor in the astrophysical sciences department at Princeton University. The galaxy gas that creates these stars "is being depleted, and is not being adequately replenished." ...

[O]ne scientist contends it could be 100 billion years out before the universe fizzles. For perspective, the universe is just 14 billion years old, according to NASA. ...

Meanwhile, there might be more immediate challenges for the universe—and again, those too are much further on the horizon. "In 5 billion years, the sun will expand and swallow the Earth," said Driver. "In 10 billion years, our galaxy will merge with Andromeda." ...

Astronomers estimate there are more than 100 billion galaxies in the observable universe, said David Kaiser, a physics professor at MIT whose work focuses on Early-universe cosmology.

But reported here previously:

[T]he heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. ... the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat . . ..
