I was just informed, much to my amazement, that the orbit of the moon is getting wider, thus the moon is moving slowly away from the earth. This seems contrary to Newton's Law of Universal Gravitation.

Would some well informed astronomer please enlighten me about this situation.

much thanks

This is an excellent site with information on the moon. Now, I've only glanced through it since I can't run much of the multi-media on my computer. (Just can't handle it.)

Though I hope the BA will jump in on this one.

As far as I know, there isn't a orbit made anywhere that doesn't change over time....Moon/Earth/Sun/Milky Way/Local Group/Universe/Dog chasing his own tail....

It's due to tides. For a longer explanation, ;-), see http://www.badastronomy.com/bad/misc/tides.html.

For scientific information, I always try to find sites with *.edu* or *.gov* in the URLs.


Of course, there are sites where there are legitimate scientists at the helm (such as BAD ASTRONOMY -- one of my absolutely best favorites) where we are lucky to have the information given at those sites. The universities and the government laboratories do not often handle the difficult cases which occur when dealing with the ignorance of the general public.

Of course, you do not learn your science from chat rooms (scientific or otherwise). In chat rooms, the sky is not the limit and there is apt to be a lot of misinformation bandied around in the name of science. Therefore, be prepared and bring your science reference books with you.

True enough, but consider two, non-exclusice alternatives to my complete gullability:
1.its intresting to see what other people think and/or
2.i am kind of lazy

anyway, if an answer looks too silly i will ususally check other sources.

Of course! It is a lot of fun to see what kind of thinking others are doing. However, to get the stuff you really want to remember, the great sites include .edu and .gov (for educational institutions and for government laboratories), and any other scientific site (such as Science online and Nature online). I have been warned about this by my scientist friends. I do not want to pick up any weird ideas. There are a lot of good ideas discussed here, however, and if you know enough about science, you can enjoy it here, too.
