Moon Chemistry Confirms Violent Origin

I don't think so. The Theory of Relativity is not wrong even if it is misunderstood and misapplied.

Define "super-religious"

[RightWhale]

Those with a doxographical outlook have adjusted centuries ago to not only other planets but human life on other planets--many other planets. Net doxological revision--zero.

Next you'll argue that Africa isn't the Dark Continent...

I still don't see exploding planets. Where does the energy come from?

Denser metals sink to the center. When enough Uranium accumulates, well....

[RightWhale]

That is probably him. Challenging dogma. Somebody ought to.

He has a PhD in astronomy and can hold his own among professional astronomers. I don't know if he is a nut, but has done excellent professional work. Retired now and able to reflect on science and push the knowledge envelope. There are loose ends everywhere in astronomy and he is pointing them out. I won't write him off. Whether others choose to ignore him is their own business.

"The fact that the moon always faces the earth on one side and faces away on the other, should have been enough proof that it came from the earth, weather spit out from some huge explosion or a collision with a very large object."

Uh, no offense, but if your physics knowledge is at the level that you would claim this, I don't think I want to be taking your opinion on the matter very seriously.

And I don't know what the public schools are teaching these days, but NASA says:

This morning at perihelion both hemispheres were 147.5 million km from the Sun. That barely differs from the greatest distance, 152.6 million km in July, which astronomers call aphelion.

I figure that at about three percent variation from perihelion to aphelion. That's close enough to call near-circular in my book.

both will eventually stop rotating.

I keep waiting for Jimmy Carter to stop rotating
but he never does!

' The reason the Moon's rotation equals its period is something called tidal lock. Eventually (in about 50 billion years) the Earth would keep the same face to the Moon as well. However, solar physics dictates that the Sun will consume both prior to this event'

That's good news.

ah, no. that's just captured rotation. not at all uncommon in the solar system.

[King Prout]

ah, you got it already. good.

[King Prout]

Total BS. Once in motion it will not stop. Look up Newton.

1. you have no idea what you are talking about
2. you have no idea who you are talking to
It would be wiser to be more polite when being given a free education by one who knows far more than you on a given subject.

As to Newtonian Mechanics as apply to inertia, you give only a partial definition, which may explain your error. The Law runs in full: "An object at rest shall remain at rest, and an object in motion will remain in motion with unaltered vector, unless acted upon by an outside force."

The tidal effect of gravitation in a binary system is an outside force.

Pick a coordinate system and stick to it. Since we are on earth most of the time, we pick earth's orbit as the zero-zero. If we were on Mars we would pick Mars' orbit as zero-zero.

Did your respond to the wrong post, or do you need to take time to actually read? When did I say anything about which plane to identify as 0-0?

[ItsTheMediaStupid]

In a frictionless system. Neither earth nor the moon nor the combination is a frictionless system. Energy is lost from both bodies by heat radiation--very deep infrared--and both will eventually stop rotating.

That makes sense. But aligning up with the same face does not. I think most agree that the moon is facing the earth because it split from the earth.

[RightWhale]

When did I say anything

Never mind.

[RightWhale]

I think most agree that the moon is facing the earth because it split from the earth.

No, they don't.
