If you look at our solar system we have a missing planet. This missing planet has left plenty of evidence if we look between the orbits of Mars & Jupiter there should be a planet. However, what we find is called the Asteroid Belt. My theory is that the Asteroid belt several millions (160 or so) ago was really a planet that for some reason it exploded killing off the Earth's dinosaurs, destroyed all life on mars by blowing away most of Mar's atmosphere. This theory also explains why the earth has such a over size satellite and why the super continent Pangea broke into seven smaller continents that are now drifting around the globe. Check the mass of the belt and moon, I think you will find there is a enough dirt floating around out there to equal a good size terrestrial planet. -- David Lawler dglmal@telis.org

Did I hear Velikovski? Let's have a go at that! You do realize, of course, that whether or not you like the sweeping, strange Velikovsky theories, unfortunately, most of the predictions made from his model (things like the voltage at the surface of the sun, etc.) turned out in retrospect to be correct and/or true. How do you explain that? All of Velikovsky's theories aside, it is pretty clear now that he was victimized by the scientific establishment of his day- people like Menzel (a local favorite around UFO groups) hated his ideas with such vengance that his writtings were censored, and he himself basically recieve the scientific establishements equivelent of "excommunication."

Ok, as a physicist and a geologist, I think this whole mess needs to be cleared up once and for all. Short lession in science history, as well as geology follows. For a long time, catastrophism was considered to be the primary shaping event of the world (ie, volcanos, and big nasty events causing large changes) that happen in a relatively short time. Then beginning in the 1700's, but having most work on it done in the 1800's, the theory of uniformitarianism came into being, which basically says that slow events over a long period of time have a significant effect, which holds quite true. Sedimentation of limestone in oceans, and the process of mountain building (which continues in many ranges to this day) are events that aren't formed in days, weeks, years, or even thousands of years, but on the scale of hundreds of thousands to millions of years. Uniformitarianism became so popular that for a while catastrophic events were considered minor players in world events, basically considered having local effects only. Of course, a more centrist view of the situation, allowing for both situations is pretty much accepted today. On the subject of the impact about 65 million years ago - a short history: In 1978, a group of scientists (including geologist Walter Alvarez, and his father Luis Alvares, a Nobel psysicist) were trying out a new technique to get the time it took for marine rock layers to form by looking at the trace element Iridium. Iridium is a VERY rare element on Earth, but trace ammounts are collected from space dust that is captured by the earth (lots of dust and other materials from space is constantly raining down - several hundreds of tons a year or more). Since the rate of dust/iridium accumulation is known well enough to suit error factors for geological ages, it was a sound model. But the Alvarez's discovered something completly by accident - an EXTREMELY high concentration of Iridium in a small layer right at the boundry between the Cretaceous (denoted as a K, from the German word) - which was the last age of the dinosaurs, and the Tertiary (Symbolized by a T) - the age when mamals pretty much took over. There's only two possibilities for this concentration of Iridium - a volcanic eruption that includes lava from deep in the mantle of the Earth, or from an extraterrestrial (meteor or comet) imact, as iridium is known to be in high concentrations in such objects. Further, other scientists started noticing that this anomalously high iridium boundry was seen globally at the same location in the geologic time scale (at the K-T boundry). Also, it was well known that there are NO dinosaur fossils above the Cretaceous, and that about 60% of all other life on earth at the time went extinct as well (so it wasn't just a dino problem). More recent studies of the KT boundry have shown an isotopic ratio of Iridium and other rare earth elements (Osmium for one) to be more consistent with an extraterrestrial origin, as well as the varieties of shocked quartz (quartz that has been changed due to a large stress such as an impact) that has been found globally at this layer. It should be noted, however, that there was a VERY large volcanic eruption in the Decan Traps in Russia at about the same time, and recent hypothesis abound right now as to them being coincidences, or possibly the impact (which was known to be VERY large) causing the vulcanism. I'm not well versed in these hypothesis, however, and will not discuss them further without more information. Nevertheless, it is nearly globally admitted by geologists that an extremely large impact occured about 65 million years ago, most probably at Chixilub (sorry if this is a misspelling) off the Yucatan Peninsula of Mexico, from an object probably in the range of 5 to 10 miles in diameter, and there is much evidence supporting this hypothesis. As far as continental drift goes, it's been going on for a LOT longer than 65 million years ago (in fact, it's been going on as long as there have been continents) and supercontinents seem to form in cycles (note, this doesn't mean all the pieces go back in the same position they used to be in at all - they just come together, then break up again, meeting each other in different configurations). There has been at least 4 of these supercontinents estimated to have existed, and possibly more. One only needs to go to East Africa and look at the African rift system to see a new ocean beginning to form as the rift splits aparts, or come here to Duluth and see one that started about 1.1 billion years ago, but stopped again (not uncommon). As for the asteroid belt, to the best of my knowledge, the total mass would only be that of a small planet or moon, but it is unlikely that it was every together. It is basically bits left over from the formation of the solar system that was caught in a gravitationally good spot, being influenced by jupiter. And contrary to some beliefs, mostly enfoced by hollywood, the asteroids are concentrated in two groups, slightly ahead of and behind Jupiter's orbit due to orbital mechanics/gravitational effects. I'm sure someone else could explain it better, but I'll find more information if people really request it. I should present a show on this whole thing at the Alworth Planetarium where I work ;o). Or at least hope a representative from a college that has a graduate program in planetary sciences might seem impressed and send me material on their program ;o).

I like the idea that extinction ocurred before the comet or asteroid hit.
If you look at the size of the colonies in the Rockies and whrere they
died, you can see that other factors, including food availabiity could
have wiped out these herds.
Can someone explain what the "traps" are in India and Siberia. Have
dino bones been found in the Western Desert of India?

There have been other , lesser impact extinctions, eg the Eocene at 39my ago, and one c 91my ago to name but two Most asteroids lie between Mars and Jupiter, but the troublesome ones (2,000 it is believed<10 kms in size) fall into 3 groups Amor, Apollo, and Aten Amors range elliptically from the Main belt to inside Mars' orbit, sometimes <0.3 AU from earth Apollos, range from the Main belt to cross Earth's orbit, while the Atens are mostly within Earth's orbit, and cross it on the way OUT to Aphelion; These come "out of the Sun", as the fighter pilots have it,mand so are hard to spot, but could make excellent sopurces of raw materials, more accessible than Luna, for a mature human civilization. It is abundantly clear that we will never achieve our full ;potential as a species stuck on earth, and that the Near Earth asteroids are providentially placed for us to bootstrap our way into the future.

You know, all through history science has ridiculed new ways of looking the universe. It wasn't until the late seventies that continental drift became an excepted theory.

The truth is meteors and > asteroids were apart of something bigger. The truth, huh? Based on ... what? Anything at all? Any evidence for that? Small rocks form by accretion, that is collisions in the early, pre-planetary solar nebula. Eventually, some get big, big enough to sweep in other rocks by gravity. These sweep up most of the matter in the solar system other than the Sun, and form the planets. They don't get everything, of course (no process is 100% efficient) and the bits they don't get are asteroids etc. How do you think big rocks form, if not via small rocks? Or are you suggesting that the planets were made on other planets?

No. With the possible exception of Mars meteors, no known meteors
are metamorphic (rock which formed and was later melted and recrystalized.)
Most are undifferentiated and consistent with rock which formed by
gradual accumulation from relatively low velocity collisions (generally
enough to at least partially melt the rock.) That's just small rocks
hitting each other and sticking together, and nothing like what you'd
expect from a broken up planet. Meteors are (in most cases) believed
to come from the asteroid belt, and represent pieces of asteroids
broken off by higher energy impacts. The spectra of asteroids matches
this theory. So the asteroid belt really does look like left over
remnants from the formation of the solar system, pieces that
never grew to the size of a planet because of perturbations from
Jupiter's gravity. There are some exceptions, notably 4 Vesta,
which looks like it _may_ have once part of a larger body. But
those are a small fraction of all asteroids, and given the mass
of the asteroid belt, the hypothetical parent body wouldn't have
been of planetary size. (Even when you add in the fact that the
asteroid belt was more massive in the past, the parent body would
probably still have been of less than lunar mass.)

And? There aren't any sedimentary rocks in the existing collection

Easily. They hit each other and stick. There is no direct evidence of
how asteroids formed, but several moons of the outer planets and
Shoemaker/Levy-9 indicate that some moons and comets are loosely
bound collections of material. So hitting and sticking is quite
reasonable. Gravity only becomes relevant when an object has
grown to a size of ~100 km.

The "truth"? Truth based on what evidence? The spectra of asteroids
shows that they were never part of any body larger than about 500 km.
Meteors probably do come from larger bodies: Asteroids. But, with
the exception of the Mars and Moon meteors, there is no evidence
that they were ever part of a body the size of a planet.
> I am not sure how the recent Galileo

Well, the Galileo data does not indicate that Ida or Gaspara were
ever part of a larger body, and the data is consistent with the
theory that asteroids are left over debris from the formation of
the planets. The main anomaly I'm aware of is that the objects
which have impacted their surface have a different size distribution
than what was expected (i.e. more large impacts relative to small
impacts.) Galileo has observed the same thing on Jupiter's moon,
Ganymede. So it isn't a process unique to the asteroid belt, just
one different from impacts in the inner solar system and from
theoretical expectations.

Two problems. First, the Moon's chemical composition resembles
the Earth's mantle, not the bulk composition of the Earth or
any other known planet. Second, the Moon's surface has isotope
ratios that exactly match the Earths, in contrast to other planets
and meteors.

The theories say this would take something like 100,000 years
before the bodies got big enough for their gravity to really
make a difference. At that point, the biggest would be about the
size of asteroids. After that, they would continue to grow
at a slower rate (as mass collects in sizable objects, the
time between collisions decreases) until the biggest ones
reached the size of large asteroids or possible lunar size.
Then the growth rates slow even more dramatically (this is
the point were the objects have accumulated everything close
to their orbits, and can only grow by having their gravity
perturb more distant objects into crossing orbits.)
> if the earth formed

You mean a planet in the asteroid belt? Basically because of Jupiter.
If Jupiter weren't there, they would have. But Jupiter got big
(started acquiring its gas envelope and becoming really massive)
around the time the asteroids were, well, about the size of
asteroids. The influence of Jupiter was enough to perturb their
orbits so that they collided at much higher velocities than they
would have without Jupiter. The higher impact velocities meant
that the odds of hitting and staying together were lower, and
the odds of hitting and braking up were greater. That prevented
the asteroids from growing to larger sizes. The terrestrial
planets (and the material which formed them) were far enough from
Jupiter that its gravity didn't prevent further growth.

How to explain.... In the early solar system, you had a proto-Jupiter forming. Most of the material was in a disk rotating about a central point. As the center increased in it's gravitational attraction, it pulled in more material. But, at a certain distance out from that center, the sidewise velocity of the materials were sufficient to keep them from getting pulled inward. Within those materials not pulled in, there were similar mass concentrations. These in turn formed local concentrations that grew into moons. But, going further out, you get to the point where the Sun exerts as much, or more, influence than does Jupiter. Materials at that point are pulled out of the Jupiter region. Some of Jupiter's moons are probably captured asteroids. > (and the moons of mars) Probably captured asteroids. > (and the moons of saturn) > ? > Same way as the moons of Jupiter. > also ... > why no asteroid belt past jupiter? > There are a number of belts past Jupiter.

You apparently didn't catch that. So please, blame one of your own, not your "heretical enemies." The best way to deal with the fanatical fringe is to ignore it. Asking it to "piss off" is a little like hoping an africanized "killer bee" will fly away if you swat at it. BTW, how *is* the New Zealand space program doing these days?

ODDBALL ASTEROID CAPTURED ON NEW VIDEO COMPUTER SIMULATION
A new computer-generated video visualization is giving
planetary scientists a fresh look at the topsy-turvy rotation
of the intriguing asteroid Toutatis, which is due to pass
near Earth on Nov. 29.
The video is of particular interest as Toutatis nears
Earth and makes its closest approach on Friday, Nov. 29, when
it will pass by at a distance of 3.3 million miles (5.3
million kilometers), or about 14 times the distance from the
Earth to the Moon. In 2004, Toutatis will pass only four
lunar distances from Earth, closer than any known Earth-
approaching object expected to pass by in the next 60 years.
Discovered in 1989 and named after a Celtic god, the
asteroid Toutatis has dimensions of 2.9 by 1.5 by 1.2 miles
(4.6 by 2.4 by 1.9 kilometers.) It is considered one of the
strangest bodies in the Solar System, given its peculiar
rotation and odd shape, which resembles two chunks of rock
connected by a narrow neck-like structure. The rocky body's
strange traits are believed to be the result of a history of
violent collisions.
