We should all get behind Howard and fake Arnold's plan to destroy the moon. It's been up there taunting us for too long.

it would take 1 nuke....

afterall the Nuclear Force is the strongest force right? :laugh:

I can't believe I actually cracked that joke :eek:

This is the logical answer.

This is the ONLY answer.

I think a few high powered nukes would make a severe dent - when you consider the moon is mostly dust and low gravity, a lot of it would be blown away.

it would probably be easier to deflect its orbit into space at a certain point instead of blowing it up if you really wanted to get rid of it...

I could actually come up with a real answer if I wanted to. I'll just half-ass it though.

mass of moon ~ 7 x 10^22 kg

In order to completely "blow up" the moon you have to give each piece of the moon enough kinetic energy to send it off to infinity. The escape velocity at the surface of the moon is approximately 2.5 km/s. For simplification I'll neglect the effects of the core of the moon having to be given more energy to escape as it is at the very bottom of the moon's gravitational well. Besides, we don't really need ALL the pieces of the moon to get to infinity before someone would look up to the sky and say "Hey, the moon blowed up!!!"

So we need to set off an explosion which will impart a force on 7 x 10^22 kg sufficient enough to accelerate it to 2.5 km/s. Kinetic energy required is:

1/2 m v^2 = 1/2 * 7 x 10^22 * (2500)^2 = 2.2 x 10^29 J

1 Megaton of TNT = 4.184 x 10^15 J

Therefore, one would need 5.2 x 10^13 megatons of explosive = way way way more than we have. Of course this assumes a lot and is very simplified but it should be within at least a few orders of magnitude.


And there you have a rough answer.

you think so? that would be fighting against the EARTH's gravitational force... I would thinking knocking it into a degrading orbit would be easier, and thne we would be destroyed when it hit earth

What a dumbass question. If you detonate a nuke on the moon, it will launch some rocks up into the moon's atmosphere, which will all likely fall back to the surface again. :p

What a dumbass. The moon has no atmosphere.

But you're right, they will just fall back down to the surface.

Our surface. Killing all the gnomes and mole people.

The moon does have an atmosphere. There's not as much of it as Earth or even Mars, but it's quite distinct from the vacuum of space. And as a reference point for how far the rocks are likely to be launched, it was apt for the comparision, dumbass.

If moon remove from orbit lack of gravity pull will cause severe coastal flood no less than 1200 km inland.

lets blow the moon up into itty bitty piece, and then watch said peices rain unto the earth cuasing wide spread destruction. sounds like a plan.
