I've heard that the Moon is moving away from Earth by about an inch (2.5 cm) each year.

Is it because the sun is getting bigger, or the tidal wave frictons? But either way, it's moving away slowly, and when it does the earth is going to spin and topple.

Also from a website i found

It is expected that in 15 billion years, the orbit will stabilize at 1.6 times its present size, and the Earth day will be 55 days long equal to the time it will take the Moon to orbit the Earth.

ouhouhhou scary! But I think that Earth is pulling the moon and that it will eventualy fall on Earth...like every orbiting objects.

Thats pretty interesting, except that you need to post the website... and the fact that the Earth probably will not exist in 15 billion years.

I say what the heck let it float off. What has the moon ever done for us? Give us something to beat the commys to lol. thats about it~

I heard this before, its because the centrifugal force of the rotation.

What has the moon ever done for us?


A lot! This can put many animals extinct because the moon controls the tides. A lot of animals depend on those.

In a Physics 101 class the professor said the Moon is moving away at 3 feet per 100 years. In a billion or so years the Moon will not be visible to the naked eye. The Earth will rotate extremely slow making day and night much longer.

ah yes, i also heard the earth is slowly slowing down as well. Days weren't always 24 hours. Nowadays they aren't even 24 hours! they're a little longer, but not by much. I've came up with theoretical (and questionable) way to fix this however. First for the moon, we build giant rockets on it and push it back to place. And for the earth we build giant side-ways rockets to move it faster. I know these ideas are stupid, but its a start.

I'm sure that in a few million years (if the human race still exists and is still on the Earth), our scientists will have a fix for that problem. I'm not too worried about it.

Funny what a coincidence. My science teacher was just talking about this today. He said something like it was leaving us at about 4mm a year.

So don't worry and expect anything to soon.

@NinjaCube. The Earth has helped us by controlling are tides. If it goes away. then the Oceans go haywire and can flood and destroy major Cities like New York City, Hong Kong, Singapore, London, Istanbul, ETC.

@Blockhead. I do not think that you will find it so funny when you see a warhead about to hit your city,town,state whatever.

true the moon will be moving, but by that time, a few things will deatroy earth

A quote from divinedarkness.
"It is expected that in 15 billion years, the orbit will stabilize at 1.6 times its present size, and the Earth day will be 55 days long equal to the time it will take the Moon to orbit the Earth."

The Sun will not explode; it is too small to "go nova." It WILL expand as it fuses the last of its core hydrogen. The outer layers of gas will swallow some inner planets (possibly even the Earth). Then the inner parts of the Sun will stop fusing, contract, and become a white dwarf. It will remain a small, hot, slowly- cooling dwarf for many tens of billions of years after that. (It will have most of the heat of a full-sized star, but only a tiny surface area with which to radiate it. Therefore, it will take a very long time to cool down. This will not help us; it will be too cold to support life on Earth by then, even if the Earth could survive the red giant phase.) Scientists based this picture of the Sun's future on the basic nuclear reactions in a star's core. The rates of these reactions depend upon the mass of the star. (smaller stars burn more slowly, and thus longer, than more massive ones, but I could be oversimplifying things.) Scientists use planetary orbits and the laws of orbital dynamics to estimate the mass of the Sun. So, with the mass of the Sun and the rate at which this mass is consumed by fusion, we can guess that the Sun's lifetime will be 9 billion or 10 billion years, total. We know (from Earth's geology and Moon rocks, for example) that the age of the solar system is 4.5 or 4.6 billion years. We think the planets formed at roughly the same time as the Sun. Therefore, based on current scientific theory, the Sun will expand in four or five billion years."

I don't think the Earth is even going to last 15 billion years.

Also, I got that info from here.

@SkullZero

The moon is about 1/4 the size of earth, so that be hard to get that much rocks, so i had a therie like yours, go to the astroid belt and smush a bunch of rocks together by using a compresser thats a part of a new space ship nasa came up with, but that will never happen because in about 7billion years the sun would have eaten us because itd be a big red giant.

rocks? who said anything about rocks? i said a giant rocket if you meant that.

Yeah and it would take like 1 bilion year to get to the astrion belt so smart tthinking but i mean if the moon does move away whaat will it do to us i mean haveing no night would be awesome.
