   Unless the impact angle is very low, any asymmetry created during the initial transfer of energy from impactor to target is lost as the crater is formed. In other words, you can come in at an angle and the explosion is going to create a basically a round crater, not necessarily an elliptical one. And the shallow crater, moreover, the shallow craters formed by oblique impact are more easily obscured by subsequent erosion. during routine flights two years ago. Now, this is from Nature, the journal Nature in 1992, so this has been a while now since this discovery. One of us noticed, and that was …

   And remember we talked about Chelabinsk that was I think around 50 to 60 ft in diameter about onethird the diameter the estimated diameter of Tangusa but you know the um the energy is the volume is going to scale according to the cube of the radius. So you can do the math on that. You'll find that the Tungusk object, even though it's three times larger in diameter, it's going to be many times greater in volume. And then presumably also in energy, kinetic energy released at the moment of impact. Now, of course, the Tungusa, the studies I've seen most recently suggested was quite a low density o…

   Firestone and his colleagues argued that the younger driers was not triggered by meltwater dynamics alone, but by the impact or multiple impacts of a fragmenting comet striking the Earth at the onset of the cold period. The evidence they presented was physical and specific nano diamonds found in sediment layers dating precisely to the beginning of the younger dryers. Tiny crystalline structures that form only under the extreme pressures produced by impacts or explosions and which have no known natural terrestrial origin at the concentrations observed. Alongside the nano diamonds, they document…

   It is estimated that trillions of asteroids crashed into the Earth and deposited a layer of heavy metals into the planet's now hardened crust. These elements weren't actually from Earth originally. All of these elements came to Earth via comets and asteroids that impacted our planet long ago and early in its history. So all the precious metals that we mine on the Earth actually came from the asteroids. The bombardment of asteroids seated Earth's crust with enough metals to make possible the Bronze Age, the Iron Age, and today's technological civilization. But many metals, including rare earth …

   And I'm going to refer to an article that I actually came back way back in 2007 as the paradigm was beginning to shift was Mike authored by Mike Ba Bailey with the department of geography, archaeology, and paleoecology at Queens University in Belfast, UK. And he is an expert in tree ring analysis. and he also spent a bunch of time looking at the evidence for climatic downturns and connected with evidence for cosmic impacts occurring or corresponding at the same time. So the title of this paper that he published back in uh 2007 in the journal of quaternary science was entitled the case for sign…

   There's very strong and compelling evidence for the uh growth and the spread of these ice sheets. Glaciers have a very powerful way in the way they uh move the boulders and the rocks that are left behind. You'll see the evidence of them being very rounded. And when you go out, you see this and it's very pronounced uh in any area that has had uh glaciation. It's a very common site to see rounded boulders and that kind of evidence close by. Along with part of this theory that I find really compelling uh is the evidence always that we read around the the whole world. There's always a story about …

   And now back to the show. And what is now a couple of hundred is probably only 10% 15%. Right? And there's a couple of other interesting developments too. When you think that the vast majority of now identified impact sites, craters and astrols are on land, but land is, you know, only a little bit more than a quarter of the surface of the earth. So right there it's fair to assume that if we include the total surface area of the planet including the oceans there has to be at least three times more of impact events which brings us up to what about 600 events or more. Right now the other thing is…

   Um so we find it in they presented this paper at this conference and they say in this review we discuss the current knowledge of impact events into marine and ice sheets and I think we can uh we can safely conjecture that there's going to be not only differences but a lot of similarities because in the tremendous heat of an impact when you might be talking 2 to 4,000 degrees centigrade or hotter at the point of impact you're going to instantly convert water into vapor whether that impact is into an an ocean or an ice sheet either way right. Um anyways it goes on to say we also discuss some of …

   That's hotter than most volcanoes can produce. The kind of heat you'd associate with an impact event when a cosmic object slams into Earth at tens of thousands of miles hour, converting all its kinetic energy into thermal energy in a fraction of a second. Then there was the carbon. The sediment layer contained massive amounts of microscopic charcoal particles and carbon spherules, evidence of widespread burning. Not just local fires, but conflrations that seem to have swept across entire continents. When researchers analyzed the carbon particles, they found they came from a variety of plant sp…

    And in both cases, yes, they found a very significant aridium spike which now they had evidence that you had uh this uh deposition of aridium both in the northern hemisphere and the southern hemisphere. Additional sites disclose that pretty much everywhere you looked at the KT boundary you found enhanced aridium. So this led to the conclusion that there had been a a dust iridium dusting of the entire earth. Now based upon the estimates of the amount of aridium that would have taken so so essentially extrapolating from say at this point I don't know four four five six different sites around the…
