I'm sorry guys... no. These things don't follow with respect to the laws of conservation of energy and momentum.
If something were orbiting at the asteroid belt, it would have to lose a HUGE, almost unimaginable amount of energy.
I guess since its orbital mechanics, the energy is calculated as negative (convention) so it would have to gain energy.
These theories don't hold up to scrutiny. If Mars were a moon of a destroyed planet, then it would still be orbiting there.
The Kuiper belt is leftover objects from when the solar system formed.
The Oort cloud is the same way. If you notice, all major KBO's (like Pluto) have screwy orbits.
Solar wobble can smooth out or disturb orbits, so you look at Mercury with its parahelion shift and all that fun stuff. Mars, you have Jupiter screwing with it.
Why is the conservation of energy 'law' the first thing people name when they hate a certain idea?
Who's imagination are we talking about here?
Feel free to explain the logic involved.
Why?
So it is claimed but have they explained why the Kuiper belt objects consists of what it seem to?
One would imagine that these orbits would have smoothed out in the last few billion years if that was really how those objects formed?
All things that would be smoothed out over time if there was no major events to disturb the orbits.

That would be because everything we've observed in the universe follows this principle.
We haven't been able to build anything that proves otherwise. No I don't want to start this friggin' debate again.
I just calculated the energy of Mars at its orbit at -1.866*10^32 J (see orbital energy convention). Even a small fraction of that would be insane to try to propulse to that energy. At 100% energy conversion, if the energy change was .000001 of that number, the necessary amount of anti-matter would be on the order of 2.072 million tons.
I honestly have no idea why the convention is followed. The best reference for this may be the Principia Mathematica Philosiphae Naturalis... Sir Isaac Newton.
Because it doesn't have a propulsive device imbedded in it. It would need to change its energy state almost an insane amount.
# Mars is much less massive than any planet not itself suspected of being a former moon
# Orbit of Mars is more elliptical than for any larger-mass planet
# Spin is slower than larger planets, except where a massive moon has intervened
# Large offset of center of figure from center of mass
# Shape not in equilibrium with spin
# Southern hemisphere is saturated with craters, the northern has sparse cratering
# The “crustal dichotomy” boundary is nearly a great circle
# North hemisphere has a smooth, 1-km-thick crust; south crust is over 20-km thick
# Crustal thickness in south decreases gradually toward hemisphere edges
# Lobate scarps occur near hemisphere divide, compressed perpendicular to boundary
# Huge volcanoes arose where uplift pressure from mass redistribution is maximal
# A sudden geographic pole shift of order 90° occurred
# Much of the original atmosphere has been lost
# A sudden, massive flood with no obvious source occurred
# Xe129, a fission product of massive explosions, has an excess abundance on Mars

Huh? What does it seem to consist of that's so weird?
The sun's influence is exceedingly weak at this point. Impacts may also help to change the orbits, but it's not a well known section of the solar system.
Missing mass dilemma
The total mass of Kuiper Belt objects can be inferred by models of the origin of the Solar System from the known mass of the planets and known distribution of mass closer to the Sun. While the estimates are model-dependent, the total mass of around 30 MEarth is expected. Surprisingly, the actual distribution appears to be well below that value, even accounting for the observational bias. The observed density is at least 100 times smaller [5]than the model calls for. This missing 99% of the mass can be hardly dismissed as it is required for the accretion of bigger (>100km) objects ever taking place. At the current low density these objects simply could not be created. Moreover, the eccentricity and inclination of current orbits makes the encounters quite "violent" resulting in destruction rather than accretion. It appears that either the current residents of the Kuiper belt have been created closer to the Sun or some mechanism dispersed the original mass. Neptune’s influence is too weak to explain such a massive "vacuuming". While the question remains open, the conjectures[6] vary from a passing star scenario to grinding of smaller objects, via collisions, into dust small enough to be affected by Solar radiation.

Um do you mean solar wobble? If it were not for solar wobble they would never smooth out because no real force would be exerted to cause them to smooth out. Actually they'd probably become more eccentric because of the outer planets and inner ones pulling on them (especially jupiter).
Dark Matter, …, we described evidence indicating that Pluto & Charon and the disruption of Neptune’s satellite system may have resulted from a past encounter with "Planet X". But in that study, the late Robert Harrington and I did not investigate the effect such an encounter might have had on any natural rings around Neptune at the time. However, since rings are made up of individual bodies that behave dynamically like individual satellites, it seems clear that a Neptunian ring could have met the same fate as other Neptunian moons – being stripped away from Neptune into an independent solar orbit that remains Neptune-crossing. Such is the present condition for the solar orbit of Pluto and its large moon Charon.
The principal arguments against this are the size of the trans-Neptunian objects (too large to be ring pieces), the implied size of the parent body (much larger than any existing Neptunian moon), and weak evidence for some low-eccentricity TNOs that do not come close to crossing Neptune’s orbit and therefore could not have originated in this way.
But whatever the origin of the curious new objects, they occupy a volume of space so vast that all the 200,000,000,000 stars in our galaxy could fit within that volume without touching! This means that the rate of collisions of smaller bodies with the larger TNOs is so small that origin by accretion is ruled out for a belt with present densities. It therefore may be concluded with certainty that something fundamental is missing in conventional models suggesting accretion of these objects from a primeval solar nebula. [AJ 110, 856-868 (1995).]

I'm open to theories, but some scientific basis is good to have when starting them.
Actually I'm not all that sure everything does but i have no major objection to this 'law' beside people seemingly throwing it around to try prove unrelated points. :0 I am a bit touchy on that one so excuse me...
Neither do i honestly!
I don't understand why you are doing math here. I am suggesting that the asteroid belt is the remains of at least one former planet that exploded and that Mars used to be it's satellite. In fact it's really not my claims and here is the qualified person who i believe originally came up with them.
While i was originally busy investigating so many of the things i used to believe i normally came to realise that on careful investigation there was no good reason to have believed it in the first place! Who of us cared WHAT we learned back in high school anyways/tech/uni anyways; the important thing was being able to pass exams and make a living . I am not sure how orbital mechanics but one assumes that the relative loss of cohesion and mass might very well contribute to the orbital decay of the remaining mass?
How much momentum would be imparted on a moon if the planet it orbits explodes? Would it be slung from the orbit and where will it end up ? Not sure but i don't think it's likely that it will remain in exactly the same orbit as the parent planet if for no reason other than the new gravitational forces by the remaining planets.

...Now some will say, prove it. I can't, though I wish I could. But can someone prove that the universe started with the Big Bang? So all is theory and conjecture. We don't even know how the moon got here!

Well, at this point, the conservation of energy is the most significant principle. It's thrown around so much by people because a lot of things get derived using it's principles.
There are a few major principles which are used all the time in orbital mechanics: Conservation of Specific Energy (Energy/mass), Conservation of Angular Momentum, some basic newtonian mechanics (general relativity only needs to be used in the case of Mercury where it has a perehelion shift), and Conservation of Momentum. There may be more, I just can't think of them off the top of my head.
I'll keep going with this debate if we can agree to keep things civil. I've got the orbital mechanics background to be able to do things with that. Last time it basically turned into a pissing contest of whose base assumptions were more correct. At this point I'm operating with those stated above.
I was doing math to show that it would actually require work by little green men to change the orbit. To go from a higher orbit to a lower orbit you'd have to lose energy which would need to come from somewhere.
You had a point later, I'll discuss it there. I'll also try to get my simulator working because I think I've found the problem with it, it's always bad to be off by a factor of 10^9 (the units in question are km^3/s^2 and m^3/s^2).
Going with the assumptions above, it would need to eject something to do that. A lot of the things you and your sources state may have been possible during the solar system's formation or shortly after that time.
The possibility I was thinking of was a lot of these things happened during formation and the planet you're talking about could have ejected Mars (like the theory for the moon). That could allow for enough energy change that it would be possible.
With the planetoids theory of early solar system formation, many things like this are possible. But, at the moment, there's not enough mass in the asteroid belt to actually form a planet, maybe Jupiter could have gotten hold of it and flung it out of the system, but the possibilities are open.
You're right here, we'd need to make a few assumptions for solving that problem, like instant destruction of the planet. Once that happens you can shift your coordinate system to the sun and find your velocity with respect to that.
As I said, I'm going to try to work with my simulator again. With something the size of Mars, I would get it would orbit at about 2 kps so the ideal situation for this would mean, Asteroid V - 2= Va.out of words.

So how did the remains develop their orbit and become rotund in such a short time
The progenitors of Venus all incarnate a being sacrificed in connection with the world of the dead. This is true in all traditions including those of Central America and Scandinavia.
They are also often associated with war or a particular conflict, as with Ištar, Athena, Horus, Parashu-Râma, Lucifer.
Greek:
The Hellenic form of the Babylonian Ištar (Venus) is Athena who springs, "fully-armed", from the brow of Zeus (Jupiter).
The planet just before Jupiter (i.e., its "head") was the "black star" Mulge, which ejected Venus from its original position as the satellite of the exploded Mulge.
In Isis and Osiris, Plutarch cites Manethon's claim that the name "Athena" in Greek evokes "a spontaneous movement". Now please have a look in the Decoder at the translations of the Sumero-Akkadian transpositions of "Athena".
The singular story of the head giving birth to a warrior goddess is repeated in Indian mythology with the Goddess Kali in the Devi Mahatmyam. Parks particularly calls attention to chapters 7.8 and 9.22, which we'll leave for you to view on that page.
