Can We Defend Earth?

Not just one weapon; tens of thousands.
The world's nuclear arsenal, if deployed all at once, has the capability to destroy the planet several times over.

Can you post your calculations for review, please? I mean, this isn't just a guess on your part, right?

lol, no. We'd get sizzled.

Nice ones. :P

I think some people could hide out, though, so there would be survivors.

Can you post your calculations for review, please? I mean, this isn't just a guess on your part, right?

Here, I'll try mine. My specialty is in small unit tactics, not physics, so I may be wrong, but this seems like a simple way to compare the numbers:

Total estimated number of nuclear weapons in all nuclear arsenals: 21,844

(Reference: http://www.cdi.org/nuclear/database/nukestab.html)

Now, half of these are tactical nukes. However, to be incredibly, incredibly generous, we'll assume that all 21,844 of these weapons will produce a yield similar to the Tsar Bomba explosion, the largest thermonuclear weapon ever detonated. This comes out to an easy 50 megatons.

So, 21844 * 50E6 = 1.092E12 tons of TNT

1 ton of TNT = 4.184E9 joules

So, 1.092E12 * 4.184E9 = 4.570E21 joules of energy in our wildly inflated estimate of the world's nuclear arsenal

Gravitational binding energy of the Earth: 2.24E32 joules

(Reference: http://en.wikipedia.org/wiki/Gravitational_binding_energy)

So, unless I ****ed something up here, the world's nukes are about 10 orders of magnitude insufficient to blow the planet apart.

EDIT: Typo.

We'll just nuke ourselves into Winter and show those aliens who's who!SeraphimGoddess

If they have the capacity to travel at faster then light speeds then they have the capacity to bombard us from orbit with Faster then light projectiles. THey'll likely be hitting us fast and first from orbit before several nukes can even land on designated targets.

If the aliens had the technology to get to our planet, i would highly doubt it. The nearest star is 4 light years away.

If we imagine the universe as a baron wasteland were very little survives, and planet earth as one of the few sources of water, which another, more advanced race is floating around trying to find - humans shouldn't be shouting out /advertising our location to everyone

That's assuming sentient life doesn't follow a set pattern of rules to exist.... if life came to this planet from an asteroid, then it probably evolves ina similarway around the galaxy

Thats a worrying thought. :(

4 lightyears away is massive.. Something going the speed of light will take 4 years to get to here.. FURTHERMORE, the energy it would take to go to that speeds are astronomical.. To accelerate something likea bowling ball any where near those speed, it would take the energy the earth produces for an entire week.. And at those speeds something the size of the marble will hit the craft with the force of a small nuclear explosion.

I just find it hilarious that people actually think that ships can travel the speed of light like in the movies.. A speck of dust hitting the hull would destroy the ship.

If E.T.'s were able to get to Earth than they obviously have much more advanced technology and we wouldn't stand a chance.

Nuke them..

Then we get PWNED.

Well we basically dont know jack poop about whats out there, however id imagine if aliens had the tech to travel billions of miles to get to earth, they would probably be able to kick our butts if they wanted.Wolls

it'd be like the Conquistadors of Spain vs the Aztecs. they would have much greater technology and weapons far beyond our capabilities. we'd be massacred. maybe the aliens would spare SOME of us, but certainly not our entire human raceeyebrowless

Guys, we wouldn't need to defend Earth, the aliens will only liberate us like how America liberated Iraq. =p

Depends on how advanced the alien technology is. IMO however, the biggest problem wouldn't be the technology, it would be how splintered we are as a race.

I could only hope that atleast in some point of our destruction we could band together to avoid anihilation..but you're right. That would be a major obstacle for us as a race.

We have the ultimate weapon right here

I thought this was a "green" topic.

8 pages for a joke topic... things have shuuuuuuuuure changed.

If a civilization has the technology to actually get here, then we don't stand a chance.

As long as they don't use those suicidal infested terrans on us, we should be ok.

I didn't do any calculations. The "blow the world up several times over" thing was just a generally accepted assumption by the people who just like big explosions.

if u see a aliens let say hello

Probably not.

If they had interstellar fleets capable of surface bombardment they'd annihilate us from orbit and we would have absolutely NO way of taking out their ships in orbit.

Nations would probably start blaming other nations for bringing the aliens or something like that.

Eh, maybe...

DJ-Lafleur

Yeah have you ever seen Mars Attack? it would pretty much end up like that :PXD4NTESINF3RNOX

we would be toast.and it would probley go like this:

Bombardment? Heh, why waste the ammunition? Just divert a sufficient size asteroid. You would never even see their ships!
