You're all going to die in 2 billion years.

Earth's Period of Habitability Is Nearly Over

Posted by kdawson on Tuesday August 11, @05:38AM
from the nice-while-it-lasts dept.

"Scientists at this year's XXVIIth General Assembly of the International Astronomical Union in Rio de Janeiro, Brazil agree that we do not yet know how ubiquitous or how fragile life is, but that: 'The Earth's period of habitability is nearly over on a cosmological timescale. In a half to one billion years the Sun will start to be too luminous and warm for water to exist in liquid form on Earth, leading to a runaway greenhouse effect in less than 2 billion years.' Other surprising claims from this conference: that the Sun may not be the ideal kind of star to nurture life, and that the Earth may not be the ideal size."

*sobs* I am going to die too young. Only 2 billion years left to live.

So basically the Earth will become like the new Venus. I once read that in 1 1/2 billion years Mars will go through a brief period of habitability too as liquid water will be able to exist on its surface for a few 100 million years.

Either way screw staying on this planet.

We will not be in physical form by then, don't worry.

Domed? Like Bio-Domed? I guess that might help.

I wouldn't write the Earth off so fast. She is a survivor, and she has beaten the odds. Our very own Moon was created in a planet on planet collision. Prior to that both worlds may have been suitable for life. So it isn't as if there isn't the potential for such an occurrence happening in the distant future that will stoke the planet back up at a later date.

They have found planets around White Dwarfs. So even a star ripping itself apart isn't necessarily a death sentence for a planetary system. In fact it probably shuffles the planetary stability into new directions. Lifeless for a way, but not necessarily forever.

Detecting Exo-planets capable of supporting life is a long way off I'm afraid. All we have found are gas giants and we've only recently advanced in technology enough to determine if a large rocky planet is orbiting a star, let alone capable of supporting life.

Maybe in 2 billion years we'll be a LITTLE closer?

Haha, yeah I guess I was thinking third imensionally and not fourth dimensionally... Touche good sir.

It's okay, I'll only live for another billion years. ^_^
