Earth Moon Collision?

[QuasarVM]

This could only happen if Ming the Merciless used his death ray on the moon and slammed it into the Earth.

Far in the future, the Moon will spiral in toward the Earth, so it is possible.

We'll let the cockroaches worry about that...

I'd imagine the tidal forces caused by it's proximity would end life on Earth as we know it long before the Moon actually hit us. Planet bulging, continents cracking, widespread volcanic activity, that sort of thing.

Dogs and cats living together, MASS HYSTERIA!!!

Hilarious!

If you took the material in the earth and moon and combined it togetehr to make a new Class-M world the gravity would not be 1 (Earth g) + 1/6 (Moon g) or 1-1/6 g. Due to the inverse square law concerning gravity and mass the force of gravity would be more like 1-1/12 g or less.

I thought the ISS had a defector dish.

Well then, all they have to do is alter the gravitational constant of the universe and they can push the moon back where it belongs.

We have to modulate the earths rotations and then tune our satellites to a higher EM field.



It's a shot in the dark but it's the best we can do.

There's rarely an all-powerful, mischievous, yet occasionally helpful entity around when you need one.

Reverse polarity!

 

[Mr. Laser Beam]

Wasn't there some lameass Sci-Fi Channel movie about this?

The orbit of the moon is slowly opening up, a inch or so per year.

Plus there is always the short tachyon pulse.

 

[Ronald Held]

Yes, but that will continue until the Earth's rotational period is the same as the Lunar orbital period. After that the Moon will start to come closer. I do not recall a link for the numbers because I did those calculation decades ago.

 

[Maurice]

The Moon is currently receding from the Earth at a rate of 3.82±0.07 cm/year, based on laser distance measurements using the reflectors left behind by Apollo.

I don't recall where I read this, but I seem to recall the the time it will take for the Earth to tidally lock with the Moon and for the Moon to migrate towards the Earth of a collision is far longer than the Sun's remaining lifespan. The Earth and Moon will both be KFCed before the Moon gets close to the Earth.
