Quaran 81:1-14

Beautiful description on the end of the Earth:

When the sun (with its spacious light) is folded up; (Quran 81:1)

The time will come when nature's processes as we know them will cease to function, and the soul will only then know by self-conviction the results of its actions. With reference to an individual soul, its resurrection is its supreme crisis: the whole world of sense, and even of imagination and reason, melts away, and its whole spiritual scroll is laid bare before it.
The conditional clauses are twelve, in two groups of six. The first six affect the outer or physical life of man; the last six, his inmost spiritual life. Let us take them one by one. 1. The biggest factor affecting us in the external physical World is the light, heat, and perhaps electric or magnetic energy of the sun. The Sun will become a red Giant and will eat the whole system around it.

When the stars fall, losing their lustre; (Quran 81:2)

Next after the sun, we can derive faint lights from the innumerable stars in the firmament. For all the ages of which we have any record, these stars have remained fixed. Nothing can be more fixed; yet they can and will fail.

When the mountains vanish (like a mirage); (Quran 84:3)

On our own earth the mountains the "eternal hills"- seem the most striking examples of stability; yet they will be swept away like a mirage, as if they had never existed.

When the she-camels, ten months with young, are left untended; (Quran 81:4)

The type of Arab property, as well as the type of the Arab pet, was the camel, and the most precious camel was the she-camel just about to be delivered of her young. She would in normal times be most sedulously cared for. But when all our landmarks of this life vanish, even she would be left untended. Nothing would then be as it is now.

When the wild beasts are herded together (in the human habitations); (Quran 81:5)

In the present world, the wild animals fear each other, and they all fear man and normally keep away from human habitations. But when this order passes away, there will be scarcely any differentiation between human habitations and the wilds of the forests.

When the oceans boil over with a swell; (Quran 81:6)

The oceans, which now keep their bounds, will surge and boil over, and overwhelm all landmarks. At present the waters seem to have reached their fixed and normal levels, but the whole equilibrium will then be disturbed.
The remaining six. viz.: the 7th to the 12th, describe the ordering of the new World, from which all present seeming incongruities will be removed.

When the souls are sorted out, (being joined, like with like); Quran 81:7)

Whereas in this world of probation, good is mixed with evil, knowledge with ignorance, power with arrogance, and so on, in the new world of Reality, all true values will be restored, and like will consort with like, for it will be a world of perfect Peace, Harmony, and Justice.

When the female (infant), buried alive, is questioned – (Quran 81:8)

For what crime she was killed; (Quran 81:9)

In this world of sin and sorrow, much unjust suffering is caused, and innocent lives sacrificed, without a trace being left, by which offenders can be brought to justice. A striking example before the Quraish was female infanticide. But in the world of Justice, full questions will be asked.

When the scrolls are laid open; (Quran 81:10)

The Scrolls recording the deeds of men, good or bad, will then be laid open before all.

When the world on High is unveiled; (Quran 81:11)

Just as when an animal is skinned, its real flesh and blood and inner organs become visible, without any outer coating to hold them together, so the inmost state of every soul will then become plain.

When the Blazing Fire is kindled to fierce heat; (Quran 81:12)

Then will burn the Blazing Fire of the Hell, worse than the fiercest fire.

And when the Garden is brought near;- (Quran 81:13)

Lastly the Garden will come in sight, not yet attained, but visible, or "brought near".

(Then) shall each soul know what it has put forward. (Quran 81:14)

This is the conclusion. It is only on such conditions that the soul reaches its full realization. Put forward: cf. "the Deeds which his hands have sent forth"

Let's see what science says:

In 5.4 billion years from now, the Sun will enter what is known as the Red Giant phase of its evolution. This will begin once all hydrogen is exhausted in the core and the inert helium ash that has built up there becomes unstable and collapses under its own weight. This will cause the core to heat up and get denser, causing the Sun to grow in size.

It is calculated that the expanding Sun will grow large enough to encompass the orbit’s of Mercury, Venus, and maybe even Earth. Even if the Earth were to survive being consumed, its new proximity to the intense heat of this red sun would scorch our planet and make it completely impossible for life to survive. However, astronomers have noted that as the Sun expands, the orbit of the planet’s is likely to change as well.

When the Sun reaches this late stage in its stellar evolution, it will lose a tremendous amount of mass through powerful stellar winds. Basically, as it grows, it loses mass, causing the planets to spiral outwards. So the question is, will the expanding Sun overtake the planets spiraling outwards, or will Earth (and maybe even Venus) escape its grasp?

According to Schroder and Smith, when the Sun becomes a red giant star in 7.59 billion years, it will start to lose mass quickly. By the time it reaches its largest radius, 256 times its current size, it will be down to only 67% of its current mass. When the Sun does begin to expand, it will do so quickly, sweeping through the inner Solar System in just 5 million years.

It will then enter its relatively brief (130 million year) helium-burning phase, at which point, it will expand past the orbit of Mercury, and then Venus. By the time it approaches the Earth, it will be losing 4.9 x 1020 tons of mass every year (8% the mass of the Earth).

Now this is where things become a bit of a “good news/bad news” situation. The bad news, according to Schroder and Smith, is that the Earth will NOT survive the Sun’s expansion. Even though the Earth could expand to an orbit 50% more distant than where it is today (1.5 AUs), it won’t get the chance. The expanding Sun will engulf the Earth just before it reaches the tip of the red giant phase, and the Sun would still have another 0.25 AU and 500,000 years to grow.

Once inside the Sun’s atmosphere, the Earth will collide with particles of gas. Its orbit will decay, and it will spiral inward. If the Earth were just a little further from the Sun right now, at 1.15 AU, it would be able to survive the expansion phase. If we could push our planet out to this distance, we’d also be in business. However, such talk is entirely speculative and in the realm of science fiction at the moment.

And now for the good news. Long before our Sun enters its Red Giant phase, its habitable zone (as we know it) will be gone. Astronomers estimate that this zone will expand past the Earth’s orbit in about a billion years. The heating Sun will evaporate the Earth’s oceans away, and then solar radiation will blast away the hydrogen from the water. The Earth will never have oceans again, and it will eventually become molten.

Yeah, that’s the good news… sort of. But the upside to this is that we can say with confidence that humanity will be compelled to leave the nest long before it is engulfed by the Sun. And given the fact that we are dealing with timelines that are far beyond anything we can truly deal with, we can’t even be sure that some other cataclysmic event won’t claim us sooner, or that we won’t have moved far past our current evolutionary phase.

An interesting side benefit will be how the changing boundaries of our Sun’s habitable zone will change the Solar System as well. While Earth, at a mere 1.5 AUs, will no longer be within the Sun’s habitable zone, much of the outer Solar System will be. This new habitable zone will stretch from 49.4 AU to 71.4 AU – well into the Kuiper Belt – which means the formerly icy worlds will melt, and liquid water will be present beyond the orbit of Pluto.

Somehow, the subjects of what came before us, and what will be here when we’re gone, continue to fascinate us. And when dealing with things like our Sun, the Earth, and the known Universe, it becomes downright necessary. Our existence thus far has been a flash in the pan compared to the cosmos, and how long we will endure remains an open question.
