The history channel's at it again. It's not historical, but it's captivating. They're doing a limited series called Doomsday: 10 ways the world will end. If the first 3 eps are anything to go by, the rest'll be amazing.
Not spoiling here, but they've already done asteroids, black holes and rogue planets, awesome stuff. Try to catch this one is possible, you won't be bored. |

Quick update: they did a double ep this time. Sorry to report, neither were all that amazing. The show's title is Ways the World will End, but these last 2 eps show humanity on the brink, but pulling out (barely).
Oh, well, hopefully they got the mediocre stuff out of the way, so now we'll get good stuff again. Seriously, folks, check out this show if you can. |

Oh no! We're doomed!
Doomed, I tell you!!!
We're all going to DIE.........

okay, just wanted to update you on this show. Ok, the eps after the dullish stuff were pretty cool, and now I think I can give a full list.
asteroids
black holes
rogue planets
nuclear war (depressing)
solar storm (lame,IMO)
gamma ray bursts
super eruption (again, kinda lame. nice effects)
orbital decay (like that TZ ep, in graphic detail)
The last 2 aired yesterday (Fri.) after a hiatus of over a month.
Alien attack (very cool, somewhat original)
Ocean current shutdown (think Day After Tomorrow, only less preachy, and no Dennis Quaid)
So, that's the 10; I'm assuming the show's run it's course, unless they decide to revive it, fat chance.
Anyhow, if you can try to watch these, they're pretty good. I know the History channel site has them for streaming (except the latest ones). |

Of all of them the most intriguing is the orbital decay theory. We know that the orbits of the planets in our solar system have been effected by gravitational anomalies in the past. The existence of "Planet Nine" in an excentric non ecliptic orbit of long duration can explain a lot. Also the existence of "rogue" stars like Brown Dwarfs can play hob with our solar alignments.
It wouldn't take much for the gravitational influence of either a star or planet interrupting the regularity of our system to cause massive solar realighnments and the end of ANY life on Earth.
This could keep you awake at night, huh? |

eh, considering the odds, I don't lose a ton of sleep over it. Still, it's an amazing subject to discuss. |

When it happens ----It happens.
You'll never know that it's just a localized conflagration like Hiroshima, Pompeii or even the London blitz----or the End of Days.
Just as far as your concerned you can kiss your a^% goodbye. |

From Forbes :
How Long Will Earth Be Able To Sustain Life?
David Bressan
The end of earth will come in 7.59 billion years, unfortunately the end for all life on earth will come much sooner.
Various geological catastrophes, like the formation of large igneous provinces (in short LIPs), pose a real danger to life on earth. One suggested explanation for the most severe crisis in earth??s history, the Permian—Triassic extinction event with an extinction rate of 96%, are the formation of the large LIPs of Emeishan (China) and Siberia.
The impact of a large asteroid, maybe together with volcanism, caused the last great mass extinction, with the dinosaurs as the most famous victims. But even without such catastrophic events life on earth will eventually perish.
As the sun grows older also the emission of light and radiation increases, by almost one percent every 110 million years. In response global temperatures on earth will rise. Warmer temperatures cause more evaporation from earth??s oceans and more water in the atmosphere accelerates the erosion of rocks. Weathering and erosion binds large amounts of carbon-dioxide in marine sediments. The sediments are subducted into earth??s mantle, melt there and feed volcanic activity, so the stored carbon-dioxide is brought back into earth??s atmosphere.
This cycle regulated and stabilized earth??s surface temperature in the last billion years and earth never was to hot or to cold for liquid water, a prerequisite of life. Eventually plate tectonics will stop as earth runs out of energy and erosion will prevail. More and more carbon-dioxide will be stored in sediments deposited on the bottoms of earth??s oceans. In estimated one billion years the concentration of carbon-dioxide in earth??s atmosphere will be to low to sustain plants or other autotrophic organisms.
Without plants also higher animals will have soon or later no food and starve to death. Without carbon-dioxide earth??s atmosphere will also lose an important gas to regulate its temperature. Strong variations will occur and eventually temperatures will drop far below the freezing point of water.
Earth will become an ice planet like some moons today in our solar system.
Microorganism maybe will be still around, feeding on chemical reactions along the last active hot springs under the ice. As microbes were the first life on earth, appearing some four billion years ago, they will be also the last survivors. In one to two billion years the sun will be so hot that all ice on earth will melt again, forming boiling oceans and an atmosphere composed mostly of water vapor.
Some extremophiles are able to survive in 170 to 240??F (80 to 115??C) hot water and for a certain time the last oceans on earth will thrive with microbes adapted to high temperatures.
As the sun becomes even hotter in two billion years all water on earth will eventually evaporate. Maybe some small pockets of liquid water will persist in the underground or the impact of a rare comet will form a short-lived lake, but most water on earth will be lost into space forever.
It seems improbable that any microorganisms, even extremophiles, will be able to survive at this point of earth??s history.

BUT, humans have an ability to adapt to environmental changes like no other organism has had the ability to do.
We, although basicly a tropical organisim have been able to adapt to arctic to equatorial conditions and beyond to the rigors of deep space. The ability of Humankind to exist is more than just a clich?? statement. It is the reason we exist.
Human life will go on----in some form ----until the end of the Universe---Until the end of days. We are fighters and it is just that aggressive part of our makeup that will cause our survival. |
