The iridium layer
Sandwiched between the limestone of the two periods, forming a clear line of demarcation, is a thin maybe one-half-inch thick layer of red clay. Immediately below this clay layer, the Cretaceous limestone is heavily populated with a wide mix of the tiny fossils of marine creatures called forams. Above the clay layer, in the Tertiary limestone, however, the fossils of but a single species of foram can be seen. The clay layer itself contains no foram fossils at all.
When Walter Alvarez brought his samples back to Berkeley, his father, LBL Nobel laureate physicist Luis Alvarez, suggested that subjecting them to neutron activation analysis could help determine how long it took for the clay layer to form. The analysis, performed by LBL nuclear chemists Frank Asaro and Helen Michel, revealed to the surprise of everyone involved that the clay was about 600 times richer in iridium than the surrounding limestone.

Then, in 1984, came a report from two University of Chicago paleontologists, David Raup and John Sepkoski, who had put together a detailed list of sea life that had become extinct during the past 250 million years. Containing more than 3,500 different species, it was the most complete extinction list ever compiled. When they subjected their list to computer analysis, Raup and Sepkoski discovered that mass extinctions occur periodically, approximately every 26 to 30 million years.
A PLOT OF DATA ON LIFE EXTINCTIONS, COLLECTED BY DAVID RAUP AND JOHN SEPKOSKI AT THE UNIVERSITY OF CHICAGO, SHOWS PEAKS IN THE EXTINCTION RATE OCCURRING AT 26- TO 30-MILLION-YEAR INTERVALS, AS INDICATED BY ARROWS
Scientists immediately scrambled to find an explanation that could account for a persistent, recurring cycle of planet-wide species die-outs. Volcanic eruptions were the most obvious suspects, but volcanoes fail to account for the clay layer, the high soot content and, most significantly, the high iridium concentrations. Casting further doubt on the culpability of volcanoes was the discovery of shock quartz and microtektites along with the iridium and soot in the clay layer samples taken from around the world.
Shock quartz silt-sized grains of quartz, which, under a microscope, show cracks and strains, is formed in the heat and pressure of a powerful explosion. It showed up routinely in rocks brought back from the moon by the lunar astronauts, but on Earth it has been found only in meteorite craters and at nuclear weapon test sites.
Microtektites are tiny pieces of glass, believed to be droplets of rock that were melted in the heat of an impact and hurled up beyond the atmosphere where they cooled. Upon reentry, the droplets were reheated. The heating-cooling-reheating sequence gave the microtektites in the clay layer a unique spherule shape.

Ruling out other terrestrial causes, many scientists turned to the heavens. One possibility was meteorites, which are chips of asteroids or planets moving randomly through space. However, a mechanism to explain the periodicity of the extinctions has yet to be found.

The trillions of comets in the Oort cloud generally maintain a slow but steady orbit around the sun. Occasionally, the gravitational field of a passing star will jar some comets loose, but few of these ever reach the inner solar system (Mercury, Venus, Earth, and Mars), as the gravitational pulls of Jupiter and Saturn acting somewhat like giant vacuum cleaners keep this part of the system relatively clean of comets and other space debris.
However, a strong enough gravitational force could dislodge so many comets that, through sheer numbers, the inner solar system's protective cleaning mechanism would be overwhelmed. One of the first possible sources of this gravitational force to be considered was the molecular dust clouds in the central plane of the Milky Way. As the solar system revolves around the center of the galaxy, it bobs up and down, periodically crossing through the star-crowded central plane that is foggy with molecular dust star stuff that never coalesced. One of the many problems with this suggestion is that measurements have shown the molecular dust clouds to be far too thinly dispersed to exert sufficient tidal gravitational force. Also, the bobbing of the sun does not match the times of extinction, in fact, the sun is close to the central plane right now.
Another source of gravitational pull that has been proposed is the existence of a tenth planet in the solar system. Called "Planet X," this planet would be a gas ball as much as five times the size of Earth, occupying a peculiar shifting orbit that is tilted at an angle to the solar plane of the nine known planets. This theory also calls for the existence of an as yet undetected inner disk of the Oort cloud, between the orbits of Neptune and Pluto. Every 26 to 30 million years, the orbit of Planet X would be shifted so that it would scrape the edge of the inner disk, sending a host of comets towards the sun. The major problem with this proposal is that the hypothetical inner disk of the Oort cloud would be unstable and could not remain a disk. Consequently, comets would be shaken loose in a steady shower over the 26 to 30 million year time periods, rather than torn loose in a concentrated storm.
A mechanism to explain the periodicity of the extinctions
The Nemesis theory fulfills all the requirements prescribed by the Raup and Sepkoski mass extinction timetable.
As envisioned by Muller, Davis, and Hut, Nemesis is probably a red dwarf, the most common type of star in the galaxy (three-fourths of all the stars in the Milky Way are believed to be red dwarfs). Less than a third the size of the sun and about one one-thousandth as bright, Nemesis might travel in an elliptical orbit that at its perihelion (closest point) brings it within a half light year of the sun (one light year is about six trillion miles) and into the midst of the Oort Cloud. Right now, Nemesis may be at its aphelion (most distant point), nearly three light years away. The sun's closest known neighbor, Proxima Centauri, is about 4.25 light years distant.

The evidence for Nemesis-triggered periodic comet storms based on cosmic ray exposure ages was drawn primarily from reviews of existing data. "In these days of tight budgets," observes Muller wryly, "the cheapest way to do research is in the library." Another review of existing data, this time by Muller and LBL physicist Donald
Morris, uncovered evidence for periodic comet storms in the Earth's magnetic field.
Volcanic rock, as it cools from the lava state, aligns itself with the Earth's magnetic field. In 1906, French physicist Bernard Brunhes discovered volcanic rock magnetized in the opposite direction of today's field. It is now known that the
Earth's magnetic field has reversed itself many times throughout the planet's history, and at times has even been switched off. Muller and Morris felt that at least
some of these geomagnetic flips were caused by comet impacts, and they developed a model to explain how it happened.
The Earth's magnetic field is generated by slow eddies in its molten nickel-iron core that are the product of the heat flow out of the core, modified by the planet's rotation. When a crashing comet plunges the world into darkness, temperatures on the land drop much faster than those in the sea because water retains heat much longer than soil. According to the model of Muller and Morris, water near the equator evaporates and is redistributed as ice and snow on the polar caps. The result is a sudden (within a few hundred years) drop in the level of the oceans. In accordance with the conservation of angular momentum, the redistribution of mass alters the rotation rate of the Earth's crust and mantle with respect to the liquid core and leads to a disruption of the magnetic field.
"It is the same as when figure skaters go into a spin with their arms extended, then draw their arms in to increase their rotational speed," says Muller. "The Earth's magnetism is so sensitive to the motions of the liquid core that it doesn't take much of a change in rotational rate to affect the field."
Prior to the work of Muller and Morris, Chicago's Raup had examined the frequency of 296 geomagnetic reversals that took place during the last 170 million years and found peaks in the rate of reversals occurring approximately every 30 million years.
Deposits of microtektites were also found in volcanic and seabed rocks from times when reversals took place. There was a sudden drop in sea level during the die-out of the dinosaurs, but there is no evidence of a geomagnetic reversal. This does not blemish the model of Muller and Morris, however, for it predicts that magnetic excursions, during which the field is turned off, would result from half of the impacts. Magnetic excursions are difficult to detect in volcanic rock.
"Our model readily explains observed geophysical correlations, and accounts for the behavior of the Earth's magnetic field during a reversal," says Morris. "Although somewhat speculative, it is based on assumptions that are considered plausible by experts in the relevant scientific fields."
A geomagnetic reversal could also take place should the polar caps melt and cause a sudden swelling of the seas. This, too, would alter the rotation of the Earth's crust and mantle with respect to the core and disrupt the dynamo.

Perhaps the most important aspect of the Nemesis theory, and the one for which we as a species can be most grateful, is that the deadly little companion star is not due to return until the year 15 million A.D.
*********************************************
There they are -- most of them -- these doom & gloom scenarii all taken out of context, made darker than a black hole and all of them, VERY CONVENIENTLY, OMITTING THE LAST PARAGRAPH!
The reason, I think, why these various scenarii are spread far and wide is simply to heavily push (sledgehammer-strength) the buttons of the planet's collective unconscious memory... planet-wide wholesale nuclear wars included (nuclear explosions origin for shock quartz and microtektites being discounted with a "How dare you consider earlier highly developed technological civilizations ever existed prior to ours?"). That same reason explains why so many people "believe" these scenarii to be real and true.
Anyway, just another side of the currency dice.
