Is there any chance that the moon can crash into the Earth when the US causes an explosion on it?
403331
No, that is not even possible. Even if an explosion big enough to do the job were set off on the Moon, if it were set off at the Moon's south pole it would push the Moon away from the Earth, not toward it. And nobody on Earth, not the US government, not anybody, has the ability to make an explosion that big anyway.

Sure why not? heck China is planning a Moon landing itself so I think America needs to start heading back up to the Moon before China does.\n\nNot to mention if we wanna get to Mars then we might wanna start building a station on the Moon so that we can accomplish our goal of getting to Mars.

Scientific research and statistics are showing that the earth will turn uninhabitable.....\n\nThat is why there is a current rush for alternative inhabitable places other than the Earth.\n\nThe Indian scientists have made a plan to utilize Mars as an alternative home, and the Moon as the source for minerals. For this, India is sending a "Chandrayan", a part of which will rotate round the Moon, and another will get into the atmosphere and land on the Moon, to get more informations. This has even made NASA to collaborate and attach their components(two) with it.\nAlready NASA is quite ahead in exploring the Mars.\n\nIts worth noting that still Neil Armstrongs team is the only one to land on the Moon, which is even controversial.\n\n\nSo, don't worry......even if the Earth is gone......the mankind is powerful enough to find an alternate option.........

Ah! that happens like one time per some 100 years!!!\nAnd besides, it will 75% chance hit the ocean! And no tsunami! And, the moon is a shield. It protects 15% of the hits! And theres a 5% chance that it will hit near you. So its a -5% chance you will "get scared" of a metor hitting Earth. I did the math!

Yes, we can and we do.  We used both the moon and the Earth's energy to help propel the Apollo spacecraft around the moon.  Gravity is actually what keeps satelites in orbit around Earth.  \n\nHowever, to be able to harness enough energy to power cities?  Probably not.  Perhaps we can harness the ocean's waves (which is caused by the moon's gravity) into some electricity, but without some major advances in technology, I don't think we would be able to make it worth the effort.

The earth would have more craters than the moon almost, had it not developed an atmosphere.  The atmosphere burns up anything trying to pass through it into a tiny meteorite.\n\nSame reason that mercury is battered with the asteroids.

I suspect you're referring to the "China syndrome," where a nuclear meltdown could supposedly bore all the way through the earth to the opposite side. This cannot happen. Any meltdown will only bore through the ground until it hits the water table, at which time it will be discharged back into the atmosphere with the steam. Even if there were no water table, the fissile material would stop when it reached the earth's core, since it cannot fight upward against gravity.\n\nThe accident at Chernoybl, if I remember correctly, never even reached the water table. It was controlled by the containment facility.

No they have not. The USSR had 3 programs to explore the moon, L-1, L-3 and Luna, and they were scaled back when it was realized that the Americans would beat them. They had planned a landing for 1968 when some disasterous setbacks made them realize it was not going to be possible. The Americans of course landed in 1969.

Look, a 1000 megaton detonation (whether it was due to a nuclear device or due to a meteor impact) would blow the line-of-site atmosphere into space.  We'd all suffer direly if that happened.\n\nA 10,000 megaton (or 10 gigaton) device would locally shatter the crust, and produce a surface wave that would do major damage to the crust all across the world.  Think of a bell: whack it hard enough anywhere and the whole thing rings, and if the whack is hard enough, the temporary standing waves would possibly shatter or crack the bell.  If you don't believe me, look at the Liberty Bell--that crack is (supposedly) due to it being rung hard enough.  Imagine that with the crust of the earth!  Pretty, it ain't.\n\nFrankly, nuclear weaponry is a silly approach to such an effort.  Throw rocks from orbit--you can get nuclear grade energies easily, and you can do it without any radiation.

no.  it affects the tides in a big way though, which can lead to weather.  But the moon doesn't affect our weather directly
196388
Neither.  Considering there is still a WHOLE lot of gravity on the moon compared to other places, it would most likely stay on the ground, but it would not get absorbed.  The pull of Earth would keep it there on the surface.  It could freeze or boil, depending on the time you are on the moon and where you are on it.

As others mentioned, the moon has no atmosphere of its own for weather patterns to develop. \n\nThe only wind the moon (or Earth) experiences is the Solar wind.  The solar wind consists of highly energy ions in the form of a plasma.  While the solar wind can effect radio signals and such, it isn't going to do anything to Neil Armstrong's footprints.\n\nThe only thing that truly disturbs the moon surface is impacts by meteorites.  This is evident by the many craters we can see.

No. The Earth is too small from the vantage point of other planets and too big from the Moon to cause an eclipse.
43014
No. The Earth's moon is terrestrial, meaning it has a rocky surface.

No, rain is caused by the evaporation of water into the atmosphere and there is no water on the moon.

Well, without the moon, we'd have almost no tides, which could present its own set of problems. Given that a lot of our weather can be ultimately relatable to tidal action, this could be potentiall disasterous, even if no fragments ever hit earth.\n\nAlmost everyone's answer concerns an extinction level event on earth, and that's not necessarily true. The earth is not a static point around which the moon rotates. Rather, due to the fact that the moon is an appreciable fractional size of the earth, the 2 combine in its revolution around the sun around a mutual center of gravity called a barycenter. Without the moon, the earth's revolution would be subject to some variation given the fact that now only the sun's gravity is affecting the earth.\n\nThe moon does rotate around the earth however; it's not just sitting there in space. Depending on the angle of impact of an incoming planetoid (at the size of the moon, asteroid would be rather small), not every impact would cause an extinction event on earth. For example, if an incoming planetoid impacted from an angle where the planetoid cuts between the orbital paths of the earth and the moon, the impact would cause the debris to enter an elliptical orbit, rather than a circular one, around the earth. It would remain to be seen if said orbit would be dangerous.\n\nIf the planetoid hit the moon from behind AND tangential to the moons orbit, very few of the fragments would actually impact the earth. The debris would continue in the original orbit, but accelerated based off the original velocity of the planetoid. This would decrease the period of revolution around the earth for the remaining debris.\n\nWhat everyone else is describing is where the planetoid would approach from outside the E/M system that would cause such huge devestation on earth. Or, if the planetoid hit the moon headon, causing a slowing of the moons orbital rate by the velocity of the incoming planetoid.\n\n"Freezing at night" is not a valid outcome; the moon shines light on us; it doesn't radiate heat. "Tidal waves" are really related to underwater earthquakes, not actual tidal action by the moon (think about it; every place on the coast experiences high and low tides 2x every 24hrs 34 minutes; if the moon created "tidal waves" every seacoast would be innundated horribly, and without the use of hurricanes!). Electric bills, as someone put, would remain the same (think about it; if it's dark outside, you turn on the lights, regardless of whether or not it's a full moon). Crime rates would probably go up a little in the outlying areas (where there is less artificial illumination to begin with), but not as horribly as someone described.\n\nJust remember: not all impacts would be bad. ;-)

I think your asking if the moon has ever been split into two pieces and the answer to that is no.  The most popular theory within the scientific community on the origin of our moon is that it is the leftover material from a collision between our earth and another inner planet billions and billions of years ago.
