New Theory: Catastrophe Created Mars' Moons

But what do you do when the Space Marines discover a demon-infested gateway to Hell?

Lock the door.....QUICK!

AHHH! Mancubus! I hated those guys. Thanks for the flashback, though.

I posted it more for the reloading double-barreled shotgun, but I'm glad you liked it for that too. :-)

lift the crust from a planet to form a moon, without a direct impact between the two bodies

Sounds so serene and decorous. Lift the crust. That's the model they taught, and it seems to be popular again. Some large body came by earth way back when and pulled the material out into space where it recollected forming the moon. It would probably work for Mars, too, even though Mars seems to have totally lost most of its material from one side of the planet anyway, not even a good-sized moon left. If Mars had a moon formed that way, it seems to be long gone, who knows where; it ought to be in a similar orbit as Mars, but there is nothing there. Perhaps Mars was farther out when that happened and has migrated inward toward the sun leaving the debris in the asteroid belt. Perhaps we'll track it down when we have done enough geological prospecting in the asteroid belt and have some good data.

And hope they don't have blasters?

It seems that where there are several bodies, moons or planets with some mass and gravity in orbit around a primary, they tend to affect each other's orbits in such a way as to circularize all of them. It might be that one of them is left wildly elliptical and that one gathers up energy and gets flung completely out of the system or sent into the primary itself leaving the rest with quieter orbits. Just like people, older neighborhoods tend to be quieter.

Yeah, you're right. I don't think we understand much about about the rotation and orbits of planets. Just looking at the earth science says that our magnetic field is created by the iron core spinning faster than the mantle. If so why does magnetic North wander so unevenly around. There appears to be more than just momentum, angular momentum, and mass involved on the orbits and rotation of planets. It could be that our planet rotates in equilibrium. Maybe the electromagnetism from the sun rotatates our core so that it's force versus the friction of the oceans and the liquid parts of the mantle create a 24 hour day, unable to speed up because of the friction of the liquids mentioned, and unable to slow down because of the electromagnetism of our core and/or the sun. Then there's the spiralness of galaxies and Saturn's rings. Doesn't make sense if there is just gravitation and momentum involved. Just too many inconsistencies for me to accept mainstream sciences explanations for the movement of plantary bodies. I spent the last day looking into some theories but it's just too broadbased to try to make a point on. :^)

The celestial mechanics problems that have been completely solved are very limited and don't represent the system as a whole. Lately computer modelling is giving some pictures of entire systems of good complexity. They throw in everything they can think of, but are they getting all the parameters?. It's similar to the problem of trying to model earth's and other planets' and stars' climates. You can get some results and maybe some inspiration, but really the technology of computer modelling is just in its infancy. How do planetary orbits circularize? Where do galactic spiral arms come from and how do they move? I don't know if there is an employed, working scientist who will say it is definitely this or that. We don't even know if spiral arms move clockwise or CCW. We don't even know they aren't a total artifact of stellar evolution rather than orbital mechanics. Of course, we haven't left our front porch yet, either, so we can't be expected to actually know anything.

Some large body came by earth way back when and pulled the material out into space where it recollected forming the moon.

Since the iron core model of the earth doesn't work for me (because of the jaggedly wandering poles), I have my thoughts on the movement of continents and the Pacific Basin also. The nature of our magnetic field with it's flips, etc., resembles more a nuclear core than just an iron core. If only 1 percent of the magnetic strength is able to get through the mantle of the earth, then there may be some other physics going on. Perhaps a Meissner effect that could have spread the continents apart.

(Just a word to the scientifically wise because this has implications that I don't want to get into publically...and that's all I have to say about that...:^)...)

Yeah, we know enough to get Voyager to go past Neptune, but that may be the basics. Do rotating bodies affect time and space around them differently than non-rotating bodies? I think studies of our satellites a few years ago proved that earth's rotation did have some kind of effect on space that Einstein predicted.

[RightWhale]

One way to find out what's down there. Core sample. A REAL Core sample from the Core. I am still entertaining the possibility that the atmosphere of earth is responsible for the earth's magnetic field. Earth's core may be iron, but it needn't be magnetized, and even though rotating needn't generate a mag field by any means including cutting flux lines emanating from the sun or Jupiter.

Could be something to consider.

Some alien tried to land a rock on Mars and used feet instead of meters in their calculations. It hit hard, broke in two and bounced up into orbit.

[RightWhale]

Singer has plans for Deimos.

RightWhale also. Somewhere in the archives is the plan, probably a couple, three years old. It's at NASA, too.

[Berosus]

I remember Dr. Velikovsky using the Jonathan Swift quote to suggest that once the moons of Mars were close enough to see without a telescope. Did he speculate on where they might have come from?

[SunkenCiv]

I'm kinda frightened of Phobos and Deimos... ;')

[SunkenCiv]

There was a paper in KRONOS (I think by Cardona) regarding that. It was suggested long ago (not by Dr V) that Swift had access to some kind of early, otherwise undocumented discovery of the moons of Mars because he gave the particulars of their orbital periods very close to the actual values. Turns out to be rooted in the view of an astronomer of his acquaintance. I'll try to check out the details when I get home.

I'm in panic myself. :)
