   They present a compelling amount of physical and other evidence of multiple impacts, giant tidal surges, massive rearrangements of the surface of the Earth, overnight mountain-building, as well as a polar shift. However, this begs the question as to how humanity could have lived through a catastrophe of this dimension, even if advanced technology was on hand. If this sort of event occured today we would be hard-pressed to survive it. Allan and Delair's book, however, is academic to a fault, and much better put together and docmented than Velikovsky. I heartily recommend it as a worthy successo…

   And again, that is going to be consistent with uh habitat loss because the larger the animal, the more food that's required, uh the more gestation time that's required, the more time to nurture the young uh to viability before they can survive on our own, uh and so on. So, when you destroy habitat, every one of those factors gets affected. Um so let's go on with this because he makes some interesting uh conjectures here. Most of the plausible cases or causes for late place to scene extinctions were under discussion in the first half of the 19th century. Currently there are only two serious con…

   Uh what we saw is that the extinction and it would qualify as a mass extinction but we're looking at you know a selective extinction the top of the food chain. You know we saw that 44 kilogram or 100 pounds in body weight roughly 3/4 of all those megaponal species in North and South America went extinct. about 35% I think we saw in the Eurasian continent went extinct and what was it 10 somewhere between 10 and 15% there's there are different ways of counting species right like do we look at an Indian elephant and an African elephant and call that two different species or one species of probosi…

   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 …

   Perhaps it is a comet or an asteroid that hits the earth. Chaos follows. In Siberia and North America, millions of large land animals, woolly mammoths, rhinoceroses, saber-tooth tigers, die instantly and become extinct. Siberia, formerly temperate, becomes tundra. North America and Canada, frozen in the ice age, go into meltdown. Glaciers miles thick on freeze, raising sea levels 300 f feet, drowning everything that was formerly at the seashore or at sea level. But a few human beings managed to survive and make their way to safe ground, carrying with them as much of their knowledge as they pos…

   In fact, I think most ecologists would concur with that and that's the big concern now. If we lose habitat, we're going to lose species. Okay. Well, that being the case, what does that tell us about about the geographic range of the intensity of these younger dus phenomena? Well, it seems like to me that North and South America were equally affected. And I think there's reason to believe even that North America was likely ground zero for whatever was the trigger. Eurasia lost wasn't rough. Well, at 35% that's not quite half of the species loss experienced by North America, but it's still signi…

   If you had an impact into the ice, you wouldn't expect a traditional crater on the ground uh because it would act like a cushion basically. Um and Lake Nippagon is very interesting in terms of its morphology. So, uh if I had to put money on it, I'd say Lake Nippagon is pretty good, but obviously no studies actually been done there. So, we we have no idea. There's a couple of smaller craters around the place that have been tentatively identified as being young, potentially related to the young. Uh but as I said if we the air burst rain theory makes most sense for the proxies that we see. So whe…

   These are, you know, tre these are devastating predators. Um, if you were alive back then, if you were, let's say, a member of a Clovis tribe, um, you know, survival on a day-to-day basis may have been not, you know, not getting eaten by the the the predatory top of the food chain may have been a major goal of your day-to-day existence. Um so right there that suggests to me that it would have been very very different. Um although a global phenomenon and this is the important point late place extinctions were highly variable in their severity in different regions which that's what we were just …

    The risk of a doomsday scenario in which high-energy physics experiments trigger the destruction of the Earth has been estimated to be minuscule. But this may give a false sense of security: the fact that the Earth has survived for so long does not necessarily mean that such disasters are unlikely, because observers are, by definition, in places that have avoided destruction. Here we derive a new upper bound of one per billion years (99.9% confidence level) for the exogenous terminal-catastrophe rate that is free of such selection bias, using calculations based on the relatively late formation…
