Yeah, I can totally buy it for the sake of shouting "WHERE IS YOUR MOON NOW?!" to astrologists, twilight fans, and other people I hold a general dislike towards.

One could also use it as a diversion. You know those times when the news just won't stop going on about some event that happened ages ago and you don't care about. Well, that's a good time to blow up the frickin' moon to give them something new to suck on.

EUREKA!

To revitalise the global economy!

See, the moon blows up and suddenly there's a humungous number of asteriods out there threatening Earth, so we need to invest massively in an emergency space-program to build three tiny ships with pew-pew lasers to go blow them up and save the day. To do this would also require loads of international cooperation, a massive re-education programme, and unnumbered other miscellaneous projects that will supply jobs and drive social change for decades to come.

Basically, planetary-scale gentrification.

Also, the view of the stars would be so much better without that giant light in he sky.

Cause in the late 2000's Humanity transformed the moon into a giant warehouse for all the abandoned nuclear weapons and now we have no other means with which to dismantle them than to blow the whole thing up?

Or possibly we dumped all of our nuclear waste on it until its mass was changed to such an extent its orbit was shifted and is now causing all kinds of problems?

It's in the way of our soon-to-be-built (and massively oversized) space elevator that we just have to build?

Alternate history: In 1968 the Apollo program completely fails and rather than having US citizens constantly look up at a Red Moon they decide to blow it out of the sky so no-one can have it? (Or alternatively, the Soviets do it)

We really wanna blow up Europa and need some target practice?

The fact that the sun and the moon appear almost the exact same size when viewed from Earth finally freaks us all out so much one of 'em has to go?

NASA wanted to land a small, unmanned rover on its surface and something went hideously, hideously wrong?

If the moon isn't with us, it's against us?

We think that's where Osama is hiding?

How about:

-A large meteorite collided with the moon and deflected its orbit such that it will fall into the Earth.
-An alien army has set up camp on the moon and is planning to invade the Earth from it
-We're trying to build an interstellar highway and the path happens to pass right through the moon
-The Russians were going to do it first so the Americans had to beat them to it

There is going to be a very large amount of dust


good point, but there are also going to be many large pieces of debris on a collision course with Earth, I doubt the dust is going to be our biggest problem

It's not a problem, because that's what we want!

The upper layers of the moon's regolith are rich in helium-3 thanks to bombardment by the solar wind. Helium-3 is highly useful in fusion reactors, so you can increase the supply by blowing the moon into dust, increasing the area exposed to the solar wind.

You call 10 ppb rich? That's 100,000,000 tons of regolith to 1 ton of helium 3.

Damn, ninja'd.

Anyway, I can add that it is possible that a new, unexpectedly large amount of He-3 could be discovered in the core? Realistic geology being ignored/violated for all I know. Hence, wanting to get it out.

Realism aside, in the context of this thread, there's only one way to know for sure - blow it up!

Yeah, but for enough energy to blow up the moon we'd first need to build a few orders of magnitude more warheads. Seems somewhat bass-ackwards to me...

The point of warheads is deployability. You can blow up the Moon with some fixed, arbitrarily large, Earth based installation, assuming this is a global effort and not a (rogue) mad scientist scheme that requires secrecy. There isn't necessarily a reverse dependency, given an appropriately magical directed energy technology :)

I could also imagine a warhead trade-off, say for stability.. one might have antimatter warheads that are safe enough for local use, but for interstellar conquest, you really need that Helium-3 stuff..

Would someone like to run the numbers on this? How much of the mass of the Earth would need to be transferred to the Moon to make a noticeable difference?

For satellites that are much less massive than the primary, the orbital period & radius is essentially independant of the mass, and the centre of the primary can be considered as the centre of the orbit. But the Moon is quite large and the centre of its orbit is certainly not the centre of the Earth, athough it is still inside the body of the Earth.

The centre of Jupiter's orbit is not within the body of the Sun. Partly because Jupiter is fairly massive, but mostly because it's so far away. (The Jupiter : Sun mass ratio is smaller than the Moon : Earth mass ratio.)

Yes, the moon has on average 40 times more orbital energy per kg than it does gravitational energy. But how do you propose to actually get ahold of that energy from an exploded moon?

Perhaps a better question could be asked: Why wouldn't you need to blow up the moon? It will achieve at least as much as landing on it did, and it's not like they had any particularly good reasons.

All I can think of is Dr Strangelove. Given how much destroying the moon would messup the earth, having a proven capability to do so seems an excellent MAD-style second strike mechanism. In the right political climate I'm sure people would pay you to develop such a thing.

How many nukes would we need to blow up the moon (also: would there be an alternative to nukes?)? If it turns out that we need to build so many new nukes that we run out of U235, it means that not only we'd get rid of the existing nukes, but that we'd make sure there won't be any more new nukes for quite a few years.

The first reason I could think of: because the moon is too bright. It shines through the curtains when I'm trying to sleep.

Alternatively, you will have to blow up the moon if you want to prevent spring tide.

By the way, there's also a petition running to have the moon blown up.

I've not written the project yet, that's what I plan to do this week. There's so many ideas here, I've had to spend quite a lot of time sifting through trying to find some that are actually viable, which sadly dis-counted some of the funniest :(

I'm going to have to go with the Hyperspace Bypass idea, basically how the Vogon's could have destroyed the moon using humanity's technology (they forgot about the moon when they packed) maybe with the inclusion of anti-matter if I'm feeling adventurous.

Actually that sounds like rubbish, I'm gonna have to keep thinking

Let's face it, you've obviously got your heart set on blowing up the moon for your science thing at this point and, realistically, no-one's going to deter you from that goal. Wouldn't it just be easier for everyone if we accept that this is now something you're going to do, regardless of reason? Isn't that enough? What more would you ask of a man?
