And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world? .(Matthew 24:3)
Mark The Date: Scientists Find 1.75 Billion Expiration Date On Earth
For those who are fastidious in scheduling on their iPhone planners, you might want to set one of those ten-minute alerts for 1.75 billion years to address any remaining items on your to-do list. Scientists have determined that, absent a nuclear holocaust, catastrophic asteroid or newWilliam Shatner album, the Earth could continue to support life for at least another 1.75 billion years.
Indeed, the calculation is not exactly precise. With a strong wind at our planetary back, we could go as long as 3.25 billion years before the Earth will travel out of the solar system’s habitable zone and into the “hot zone.” We have only been around for 200,000 years, that is still a fairly generous amount of time.
The research can be found in the journal Astrobiology where the total time for the Earth in the habitable zone is calculated at 7.79 billion years.
the Sun continues to burn through its nuclear fuel, it burns faster and more luminous, and over time, that increased energy output will be sufficient to increase the surface temperature of the Earth above the boiling point of water. And when it does, the oceans will cease to exist, and so will the basic biological processes that drive all life on Earth as we understand it.
In one sense, one-to-two billion years from now, that will be the end of the world. But in another sense, the Earth will still be here, albeit devoid of life, just like all the other worlds (we think) in our Solar System. But even that will not last forever.
Because in five-to-seven billion years, the Sun will run out of hydrogen in its core and become over a hundred times as large and luminous as it is today, entering its red giant phase. At this point, it will roast the Earth with wave after wave of ionized plasma, stripping off our entire atmosphere and possibly engulfing our entire world into the central star itself.
the sun will eventually expire there is Big explosion
The Sun will gradually die. As a star's core crashes inwards, it eventually becomes hot enough to ignite another of its constituent atoms, helium. Helium atoms fuse together to form carbon. When the helium supply runs out, the centre collapses again and the atmosphere inflates. The Sun isn't massive enough to fully re-ignite its core for a third time. So it goes on expanding, shedding its atmosphere in a series of bursts... The dying core eventually forms a white dwarf - a spherical diamond the size of the Earth, made of carbon and oxygen. From this point on the Sun will gradually fade away, becoming dimmer and dimmer until its light is finally snuffed out.
Out of fuel, the sun will approach the beginning of the end. It will grow to an enormous size as the last gasps of helium and hydrogen are blown away. It will become 180 times larger than the sun we know and thousands of times brighter. Huge quantities of its atmosphere will be thrown off into space, until nearly half its mass is lost. The loss of mass will cause the planets Venus and the earth—-now little more than burned-out cinders—-to move even farther away.
A black dwarf is a hypothetical stellar remnant, created when a white dwarf becomes sufficiently cool to no longer emit significant heat or light. Since the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe of 13.7 billion years, no black dwarfs are expected to exist in the universe yet, and the temperature of the coolest white dwarfs is one observational limit on the age of the universe. A white dwarf is what remains of a main sequence star of low or medium mass (below approximately 9 to 10 solar masses), after it has either expelled or fused all the elements which it has sufficient temperature to fuse.
"Black dwarf--The sun shall be turned into darkness
But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.(2 Pet.3:7)
The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:(Acts 2:20)
Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:(Matthew 24:29)
A panel of scientists at the annual meeting of the American Association for the Advancement of Science described the situation in 2000, and it still holds true. Astronomers generally agree that the sun will burn up its hydrogen fuel supply sometime in the next 5 billion to 7 billion years. As it does, gravity will force the sun to collapse into its core, which will ratchet up the heat on the remaining hydrogen and cause the sun to expand into a red giant.
At this point, the sun will swallow the Earth.
And yet, the many atoms that made up the Earth, that made up past and (relative to us) future life on Earth, and that make us up right now, will be returned to the interstellar medium, where they will someday make future generations of stars, planets, and possibly living creatures once again.
There are some real catastrophes that can cause the extinction of our species. These can be man-wrought, such as through catastrophic modification of the environment, global nuclear war, or collapse of the food chain, or it can be natural, such as an “Earth-killer” asteroid strike, a very nearby supernova, or — perhaps most prosaically — enough time, genetic mutation, and natural selection so that our surviving descendants, long-term, cease to possess the qualities that we have determined “make us human.”
The real end of the world is not yet upon us, but when it does come, it is far more wonderful and terrifying than any doomsdayer has ever prophesied. And I hope you never forget just how spectacular and precious your existence — in the midst of all of it — happens to be.
That, truly, will be the end of the world.
For verily I say unto you, Till heaven and earth pass..."(Matthew 5:18)
