Even if you were right that you said you never said why it was moving away (gravity failing lol), you'd still be wrong, because the Moon isn't going to dislodge itself from Earth's orbit and then crash into us. That's just hilariously wrong.

omg lol think about how close the moon is to us, if it starts to orbit the sun its orbit will be close to ours... hence a collision will occur... The universe is the most collision prone place anything that can happen, will happen

The moon is already orbiting the sun (in addition to the earth). You're just wrong, there's no other way to say it.

The moon moves 2 inches away from the earth per year. This is because it moves fast enough thats it's centrifigul force is greater than the earth's gravity.
I hope you all die for how stupid you all are by the way.

it moves closer to the sun each time it is on that side of the earth, it averages out at around 3.8 centimeters (whats an inch?) yearly. one thing i dont understand about this theory is that the moon should get closer to the earth when on the opposite side of the sun (earth's and sun's gravity working in unison).

also just read that many scientists are abandoning the theory that the moon formed from a giant collision, they think the earth accellerated faster than gravity could pull all the matter back in. the moon was what was left during the creation of earth.

Well actually

I agree with you guys

but..

just wanna throw out there..


Dark Energy is expanding our universe and separating everything in it. In only 45 billion years (I think) absolute zero will be reached. A shock wave in the sun formed by the sudden collapse of the sun's outer [crust?] by the cease of nuclear fusion (outward energy keeping a star from collapsing into a black hole by its gravity) will travel from the collapsed matter in the core to the edge, and bring much of the matter of the star with it when it continued out into space (easier to think of it that way). This is called a super nova. Our sun will experience it in somewhere around 5 billion years. that's 1/9th of the universe's active life. That gives plenty of time for dark energy to increasingly make everything further apart, combined with the slower, 1 inch per year.

if you add in dark energy it just might be possible for the moon to lose orbit of the earth before the sun implodes

probably not though

Our sun's not massive enough to go supernova. Once it finishes burning through most of its hydrogen, it'll being to burn helium. Eventually energy produced will be too great to be held back by the sun's gravity and it will begin slowly expanding. Over the course of a few million years, it'll expand to a red giant and engulf the inner solar system (so long, Mercury, Venus, Earth, and Mars). Once it finishes burning helium, it'll again contract and eventually become a white dwarf where it will slowly and unspectacularly burn out the last of whatever remains.

One thing I never understood:

If dark energy causes the expansion of the universe, and the expansion of the universe causes the space between galaxies to expand, and this causes light's wavelength to expand, then why doesn't the expansion of the universe tear galaxies and matter apart? It's supposedly expanding at a very fast rate.

the theory is that supermassive black hole > expansion

naw...naw man
