The Giant Impact Hypothesis

The giant impact hypothesis—the favored scientific hypothesis for the formation of the Moon—proposes that the Moon was created from the debris of a collision between a young Earth and a Mars-sized celestial body. Evidence for the hypothesis includes Moon samples indicating that its surface was once molten, the Moon's apparently relatively small iron core and lower density than that of Earth, and evidence of similar collisions in other solar systems. What evidence is inconsistent with the theory? More...

This should be an interesting discussion between science and religion. >^,,^<

There are problems with both leading theories. There are problems with moon formation in other planets too http://www.spaceref.com/news/viewpr.html?pid=16985
Not surprising given that moons are lumps of celestial debris. People still worship them though.

apart from the literal six-day theorists, this is actually evidence of how special Earth is, which is always a popular point with religions.

The collision makes Earth the right size and gravity to hold atmosphere and water, but also allow mobile life forms (us!)

the presence of such an unusually large moon makes for very high tidal differences, and a source of food for humans from the accessible and fertile intertidal areas.

A rare anorthite (white mineral) moon, has a high albedo which means us poor-sighted humans can see at night, so we are not as inferior to the supposedly 'lower' life forms than we would normally be!

the collision allowed the accretion of a greater amount of heavy elements on earth, which are the radioactive ones that keep it warm enough to drive plate tectonics. Without that extra heat the world would have ground to a halt like Mars. Tectonic movement drives mountain building, erosion and the production of fertile soils. Without it you just get wind-dust.

So, in religious terms, this collision was absolutely necessary to make this a livable place for the creation of a paradise for God's human creations!

Sort of feels like a late microsoft patch when the plan began to go wrong, though......Brick wall

thar,

I don't think the religious groups, most of them, care two hoots about mother earth or how special she really is.Eh? They think in linear terms as opposed to the circle of life, meaning our lives depend on what goes on around us.

The end line, above, is how I think and believe some religious groups think and teach. The teach that, god comes first, then us, and then the animals, plants etc. They teach that these are lower forms of life. And they aren't. These living things were put on this earth, if one is to believe in the "good book" before us so they are more important than us, as we can't live without them............despite what some may think.Think

We can't exist with out plankton, paramecium, etc as these small creatures each play a role in the chain of survival.

We are not the smartest creatures.Speak to the hand We are constantly wondering if there is life on another planet, and there may be, and we can't wait to get there, (some of us,) which is sad as we can't even take care of our own mother earth.

Man is a funny creature.

just some thoughts.Anxious


peace out, >^,,^<

Nice stuff.

Very much so -that is the way life goes. And pedro has addressed quite a point there... -close to the tip of the universal nose. Congrats, p, t & k.
