I stole the spaceship with all the caffeine
from the other thread.

just in case .. i am going to pay closer attention to the sky . Usually I just look at clouds and stars . I agree poetry ..there will be lifeforms that could potentially survive an extinction event but unless someone has hidden away human DNA in a time capsule on the moon .. humans are more vulnerable ..

hope you kept an alien hostage to fly that ship

Fly?
It's a spaceship, designed and built
to withstand the vigors of space travel.
As such, I'm sure it will be adequate shelter
in an E.L.E..

Plus, I have the entire supply of caffeine.


It's all good.

The Deep Impact scenario is shallowly realistic but unlikely.
The world maps NEOs constantly. We track larger asteroids.
Wolf-Biederman was larger than the large asteroids we already know about.
99942 Apophis made a close approach to the Earth in December 2004.
We know it will return in 2036. 99942 Apophis is 600' radius which makes it a diameter of 1200'.
Wolf-Biederman was 7 miles across. It was a comet. Comets have tails.
We track comets all the time.

There's no way a nuclear strike of any size is going to split a 7 mile wide comet in space. If anything, causing a deflection blast near the comet could cause it to deflect, if it has a strong enough composition.
My point is, the entire solar system is in constant motion and we have been tracking objects for quite some time.
If something is going to hit us, we will see it way before it becomes an ELE threat.

As for the spaceship idea.
Also not gunna happen.
We don't have the technical ability to launch a ship to orbit able to house any significant survival force.
Then you have the problem of cosmic radiation outside the Earth's magnetosphere.

And...even if we can build such a ship, outfit it with cargo and supplies, its not going to be enough because at the speed of light the closest star that is not the Sun is Proxima Centauri which would take 4.5 years at the speed of light to get there. Then, there is the fact that we don't know where habitable planets are yet. So if Proxima Centauri has such a planet, we have no way to safely land on it.

If we attempt to settle in the solar system, we are still going to have the landing issues but also non-habitable planets and moons for a destination. Not only would we need to deliver a habitat station and supply it, we would need to set it up and there will be no organic resources so it would require us planting gardens and carrying food animals that can reproduce.

Then, there are the effects on the human body in micro-gravity.
You will have hundreds or thousands of people living for years in micro-gravity. If they make it to a habitable world, their bodies would be unable to take the strain of gravity.

Then you have the fact that large groups of people in a closed environment would tear themselves apart. It might start out as a group of professionals but after a relatively short time, there will be wars and destruction. All within the confines of a fragile space-borne habitat.

There is also the possibility that an ELE will not originate from space.
The Earth is over-populated. Mega-pandemic viruses exist.
Yellowstone super-volcano is past due for an eruption.
There are so many different End of the World scenarios possible its crazy.

Would I get on it...NO but not for any of the reasons given so far.
I wouldn't get on it because, well, what's the point? I'd rather die quickly than dies slowly from cosmic radiation, lack of gravity, carbon dioxide poisoning or closed space riots.

However, if there were a colony ship being launched with a destination in mind and the ability to sustain people over long periods of time, I'd get on it. Problem is, that doesn't exist and will never exist in my natural lifetime.

As for bunkers and caves, if a 7 mile wide asteroid were to strike the Earth at full force, the atmosphere would be rendered incapable of sustaining life. So the cave and the bunker would not have air. Even if an air supply is there, it is a finite solution to an infinite problem.

Even The Martian (2015) is a fantasy scenario scientifically.

On your space ship you would need everything needed to maintain the ship (including fuel).
Room for the people.
Room for the food that supports the people. Not over a long period as much as during the initial year of the journey.
Room for livestock.
Room for ecological specimens and everything needed to maintain those specimens.
Room for water and air.
Something that can generate reliable Earth gravity of duration.

You might say just spin the habitat but spinning such a mass would require energy and those rockets need fuel too.
Plus, all occupants, including the animals and plants, which require gravity too, must be able to live where the gravity is, out on the outer shell.

Now you have a ship that is so massive, it can't break Earth's gravity at launch. If it is built in space, all the voids in the ship will need to be supplied with air, that means launching all the materials as well.
Realistically, it couldn't be built in the relatively short time it would need to be.

Plus, the occupants would need to be launched to the completed craft in multiple launches which require precision technology that is currently fraught with failures.

We would need to refocus our dedication decades, if not centuries, ahead of the ELE just to have a space exodus option.

To quote Pink Floyd...
"Goodbye, cruel world. Goodbye."

I have my towel, and I know how to hitchhike. You Humans are on your own.

I wouldn't go!

If i had a ticket I'd give it to someone else (prolly family)...even if I had more than enough tickets I wouldn't go ......coz, I think it would be pretty interesting to watch all the chaos on earth than to escape and live~


(The above statement is invalid If that spacecrafts destination is a more chaotic planet(aliens,monsters etc))

the space around Earth is huge, it can't be watched 100% of the time no matter what..our government funds most of the space observation posts anyway, so they can control information... Just last week, they found a meteor the size of a 17 story building, gunna pass between the earth and the moon at about ¹150,000 miles from us..a "very" near Miss, in astonomical terms...

I forgot to say it will pass by earth (hopefully) tommorow, sat. The 8th..

Only the Illuminati would get the offer.

Myself I would give it to any family member that wanted to go.. Mainly grand children hoping they could make a better world to come in the future..

For I would not leave my family/friends instead I would party like it was 1999 till the end comes...

Aww anyone that thinks our Government does not have secret plans to ensure survival for the elite is fooling themselves.. But no matter what they have planned there is no guarantee's they will survive...

A meteor the size of a 17 story building is not an extinction level threat.
Biederman was a kid looking at the sky with a bunch of other kids. Wolf was the astronomer Biederman's teacher sent the coordinates to.
Then suddenly, Wolf couldn't contact anyone and it gets silly from there.

In reality, we have computer programs that digest observational data looking for changes. If someone can see it, the data is there. If the computer doesn't flag it, no one will know unless some astronomer is actually doing their job and not incompetent.

The thing is, if one is detected, we don't have the technology to do anything about it that will matter in the long run.
You can see someone fire a gun at you but there is nothing you can actively do once the bullet is on its way to your head. Only random chance is going to make you lucky.

Most people won't die from the collision. They will die from the after effects of the collision.
There's also a greater chance of it hitting water than land because there is more surface area of water. Thing is, a projectile that big, it won't matter. You wouldn't get one killer wave, you would get a whole series of waves as the water is pushed outward, then refills and rebounds again and again.
Plus, the crust of the Earth at the impact site will liquefy and be shot into the atmosphere. The atmosphere would essentially be on fire and all that material will fall back down onto the Earth as fire.
The Sun will be obscured for decades and plant life will die, then animal life will die. That's if the animals don't die because they no longer have a good atmosphere to breathe.
Just like what happens in the water will also happen to the land because the Earth sits on crustal plates. An impact of that magnitude will shift the plate and those caves and underground bunkers where you think you'll be safe will experience a series of earthquakes. The shifting plate will also cause volcanic eruptions.
You might think you'll be safe on the other side of the planet but an ELE like this would be massive enough to transmit its impact forces thru the planet to the other side.

People might think their governments have a plan for the elite but there is no plan for a species survival scenario on this scale. This is because there's a lot more to it than loading a bunch of people on a rocket ship and launching them to space.
How many times have we launched even 100, 50...20 people into space at the same time? We just don't have the technology. We are not even close to that technology.

It doesn't matter who detects it. It better be over a century away because even if we pool our resources and work together as a species we will be hard pressed to be able to do anything that will make a difference.
I mean, we can't get along even when there is no threat of extinction pending.

If one is discovered today. They will know when it will impact us in a few days or weeks. Even if they told everyone and all our resources and technology shift towards an exodus. We couldn't do it in time. At least not in the sense of species survival. Too many unknowns and not enough cooperation.

Might as well just pray or try to will it away. It would be just as effective.

I'll just hop into my teleporter and head to LV-426. At least there, I would have a chance.

from wiki - 99942 Apophis
Asteroid
99942 Apophis is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a probability of up to 2.7% that it would hit Earth on April 13, 2029. Wikipedia
Radius: 600′
Mass: 26.99 billion kg

Apophis was discovered on June 19, 2004.
On December 21, 2004, Apophis passed 0.0963 AU (8,950,000 mi) from Earth.
The Moon is 238,900 mi away. That's 37 (and a half) times further away than the Moon.
At only 600 ft radius if it hit someone would probably get a headache but it wouldn't be an ELE.

For roughly 6 months we knew it was coming. That is not enough time if it was an ELE. But, if it was an ELE it would be massive enough to detect earlier. Still, we don't have the technology to do anything about it.

Search for realistic solutions to asteroid and comet threats.
You'll find there are few that believe a nuclear blast will be effective.
They aren't rocks, they are clusters of material that has clumped together.
If its big enough for gravity to make it into a ball, its probably big enough to be an ELE.
The velocity and mass is what kills and destroys, not the fact that its a rock. Its simple physics.

The best idea I have read is to park a mass beside the object and try to use that mass to divert its path. But that takes a lot of mass and an early launch.

http://en.wikipedia.org/wiki/Asteroid_impact_avoidance
As you can read at that source, there are nuclear strategies that COULD work. None of them are going to vaporize a massive object tho.

http://en.wikipedia.org/wiki/Standard_asteroid_physical_characteristics
For the majority of numbered asteroids, almost nothing is known apart from a few physical parameters and orbital elements and some physical characteristics are often only estimated. The physical data is determined by making certain standard assumptions.
In other words, its anybody's guess.

Since we don't know, we can't apply a solution effectively.
It its loose material and we send a crew up there to drill and set nuclear charges it won't work and it could make the collision even worse.
Then you have a crew racing that thing back home.

How Big Does An Asteroid Have To Be To Destroy All Life?
http://www.youtube.com/watch?v=1agg2fOlpxc
answer: about 60 miles
The KT event 65 million years ago was around 7 or 8 miles.

To lead to a global catastrophe, an asteroid or comet only has to be big enough to launch large amounts of dust in to the atmosphere. That leads to the abrupt change in climate that wipes out species.
