Question

Taking votes for how the world will end, any guesses?

Answer 1

Looking at the odds, I think the most likely scenario is that a massive object (meteor, asteroid, etc) collides with the earth and destroys it.  

Answer 2

THE POLES WITH SHIFT.

The North and South poles will be oposite. This will cause major destruction to our world and people. It will cause flooding beyond belief plus huricanes and tornadoes and rain and the clouds will cover the sun. We will not be able to grow crops to eat and we will not have good water to drink. The coastlines will all disappear under water. We will watch as illness spreads over the land. People will die in droves and animals will die first.

Our planet will suffer under the strain. Mother Earth will cry and groan and clear away all debris (humans, animals and plants). And then she will start A NEW.

Answer 3

We will blow ourselves up in the name of religion.

Answer 4

The Earth has been going through violent and drastic changes for billions of years and always bounces back.  This will continue until the Sun goes out.

Answer 5

The world won't end. Humans may someday become extinct, but that does not mean that the planet will just disappear or blow up just because the humans are gone. The world was here before we came along and it will be here after.  

Answer 6

Thats easy, its when you die.

Answer 7

How the next mass extinction of life on this planet will occur?  I have no idea.  But the planet has been through several since life showed up, and life keeps coming back after each one.  How this world will end, however, is that in several billion years, having fused all its hydrogen into helium, the Sun will likely start to expand into a red giant, before collapsing back in on itself to become a brown or white dwarf star (our sun is nowhere near massive enough to create a black hole).  During the expansion phase, it will probably swallow the terrestrial planets.  Certainly it will expand to engulf mercury and Venus.  Even if it doesn't quite make it out to Earth and Mars, it will certainly cook us up to a pretty cinder.

Answer 8

(1) Natural occurrences

These include:

A global pandemic.

A geological event such as massive flood basalt, volcanism, or the eruption of a supervolcano. One such event, the Toba Eruption, occurred in Indonesia about 71,500 years ago. According to the Toba catastrophe theory, the event may have reduced human populations to only a few tens of thousands of individuals. Yellowstone Caldera is another such supervolcano, having undergone at 142 or more caldera-forming eruptions in the past 17 million years.



A gamma ray burst or other devastating blast of cosmic radiation.

One especially deadly hypothesized source is a hypernova, produced when a hypergiant star explodes and then collapses, sending vast amounts of radiation sweeping across hundreds or even thousands of lightyears of space. Hypernovae have never been observed; however, a hypernova may have been the cause of the Ordovician-Silurian extinction events. The nearest hypergiant is thought to be Eta Carinae, approximately 8,000 light-years distant.

An abrupt reorientation of Earth's axis of rotation.

A drastic increase or decrease in the Sun's energy output.

An impact event caused by the collision of a large meteoroid, asteroid, or comet with Earth. A common theory postulates that the extinction of the dinosaurs occurred approximately 65 million years ago as a result of the Cretaceous-Tertiary extinction event when a large asteroid struck the earth, producing atmospheric dust which blocked solar energy and caused a significant lowering of temperatures worldwide. Evidence for this theory includes a sedimentary layer of iridium in the geological record and a large crater in the area of Chicxulub, Mexico. The Tunguska event (1908) was on a much smaller scale.

A sudden change in the physical constants governing the universe, such as that created by a Vacuum metastability event.

The effect of a black hole on the planet Earth.

An exceptionally devastating hypercane.

A universal Big Rip or Big Crunch ("Gnab Gib").

Severe global warming or other climate change, can also be caused by anthropogenic sources.

(2) Non-natural or events

These include:

The creation of a black hole on or close to Earth.

Depletion of oil or other important natural resources, assuming that alternatives are not explored.

Strangelet accident.

A nuclear, chemical, or biological war.

A cybernetic revolt.

A grey goo inundation.

Alien invasion.

(3) Supernatural events

These include:

An act of divine retribution or the Last Judgment. Many religions include beliefs pertaining to the end of time.

The Norsemen believed that the world would end in a tremendous battle of the gods known as Ragnarok.

In the Christian Bible, the Book of Revelation describes Armageddon, a final battle between the forces of God and the forces of Satan.

In Hindu mythology, it is believed the Lord Vishnu will assume his tenth incarnation called Kalki Avatar to destroy the world.
