The Moon’s Long Lost Twin Found
International Business Times ^ | 8/11/2011 | International Business Times

The moon maybe palely alone in the night sky today but according to scientists it is possible that the there was a second, smaller moon 4.4 billion years ago.

A paper published in the journal Nature theorized that there was a smaller moon created in the same impact that created the moon. Astronomers, Martin Jutzi and Erik Asphaug of the University of California at Santa Cruz have long wondered why the moon had two incongruous sides, one smooth with flat plains and another side full of rugged mountains and craters.

The astronomers started thinking that the mountainous region had been added to a pre-existing surface. This theory follows the generally held belief that the moon was formed after a Mars-sized planetoid crashed into Earth to blast a cloud of debris into space that would eventually congeal into the moon. Smaller pieces could have formed at a Trojan point or a place in the same orbit as the moon but ahead or behind it.

The mini-Moon would eventually become gravitationally unstable and would fall back to the bigger Moon. Jutzi and Asphaug's computer simulations of the event show that the Moon's smaller twin wouldn't fall back to the moon in a fiery explosion but in gentle descent. Not with a bang but with a splat.

"Being slow, it does not form a crater, but splats material onto one side," Professor Asphaug said. The extra mini-Moon mass would account for the extra material on the far side of the moon.

The scenario also explains other features found in the moon including why the side facing Earth has so much lava. At the time of the impact the extra mass added to the other side of the moon could have moved the magma beneath the crust upwards to the near side of the

Thanks for posting this. Fascination subject. Too bad the Flat Earthers had to stink up the thread, but it serves as an abject lesson on the macelency of civilization’s veneer.

What's the saying? "Science is hard. Harder if you're dumb."

Eternity has no beginning or end so all find
themselves in the now, recognizing that is to
know your intellect as the void, blissful and
shining.

You know, the difference between countable infinity (chaos), and uncouncountable infinity (entropy), escapes some people. Moreover, the very idea of random events makes them soil their shorts.

So they seek an illusion of control ...

That is actually a survival mechanism. I once placed a mouse in a glass cage, next to a snake in a glass cage. In about 12 hours, the mouse dropped dead. It had food, water, and it was protected from the snake by the glass.

I didn’t autopsy the mouse, but I am pretty sure it died of stress.

So, if we throw a virgin in the volcano, G-D won’t drop a burning rock on our house...

"How do you know this 'authority' knows what they are talking about and not deceiving you? Making you believe what they want you to believe? Putting trust in 'man' is for the gullible."

Exactly. How do we prove anything to be the word of God when it is all recorded on materials made by man? It is physically the same as any text that could easily have been changed by any man. It doesn't help that most of the texts were written many lifetimes after the fact.

If even one text or relic had supernatural properties that could not be explained or reproduced, I would be more likely to believe it. In fact, other cultures have more unexplainable relics to show. For example, the perfectly symmetrical Egyptian statues that can only be replicated through robotics. Or buildings perfectly aligned to stars within 1/100th of a degree, something barely.

Right now I see Biblical texts as edited and compiled by many men for their own purposes. Even if some men in history received the direct word of God, it was still written down and kept by men. You must THINK and not put complete trust in anything made by man, just as you said.

ok, let me give you more detail. My kid was off at college or the like, and I was feeding his pet snake. It ate live mice.

We had two glass cages, a big one the snake lived in, and a smaller one for feeding - don’t feed a snake in it’s home, or it will assume that anything that moves in it’s home is food, and you will get bit.

So the procedure is take the snake out of it’s home, put it in the feeding cage, and chuck in a mouse. Snake eats mouse.

But we had two mice, so once the snake had eaten, I put it back in it’s home, and set up the spare mouse in the feeding cage with some food and water, for the next time the snake needed to be fed.

Hours later, it keeled over, dead. I should have put something between the two glass cages, so it couldn’t see the snake staring at it.

But you “all” can believe whatever you wish.

Thanks U-238. Pinging to an update. This is not, however, really an X-Planets topic.

It saddens me that some people are ignorant of what scientific progress has done to improve the quality and quantity of their lives. Science does not have to be in opposition to religion and religion does not have to be in opposition to science.

Oh PLEASE - SAVE THE DRAMA!!!!!

Besides this has NOTHING to do with religion, so much for this 'ignorance' you speak of!.

That’s a curious statement coming from someone who hijacked a science thread and made it all about religion.
