In the early stages of disintegration, there will be clumps, where as the Earth is passing through, the probability of an impact may be increases by a couple of orders of magnitude. And it's the analogy I use is imagine you've got a racetrack and all these cars are racing around it, and then you've got just this empty country road that comes and cuts across the racetrack.

And if you're driving on the empty country road, there's no other traffic, your chances of having any collision are going to be very, very slim. Now, you hit the racetrack and you cross the first roadway of the racetrack. And now let's assume that it's early in the stages of disintegration. And so you've got your race cars are all clumped together pretty much.

Right or even like if you watch a track meet the runners all start out together and then Later on they're all spread apart same idea. Well if the clump is over here when you're crossing your chances of Collision are small but if you're crossing and the clump is right there at the time the cluster or whatever now your probabilities increase enormously and

And it's going to take, like the torrid meteor stream now is relatively diffused. But the evidence suggests that it was originally a very, very large comet that came into the inner solar system between 25,000 and 30,000 years ago. And what we now see is the torrid meteor stream is a remnant of the breakup of this really large comet. And it's very possible that that comet

the influx of that material into the inner solar system and into an earth crossing orbit is what led to the final phase of the great ice age. Because remember I was talking about there being that intermediate period where it looked like there was forest growing in Canada. Well, that appears to have been over by sometime between 25 and 30,000 years ago. And then the ice began to rapidly re-expand.

So a hypothesis might be is that comet comes in, breaks up. One thing might be is that a lot of it might end up as cosmic dust. Earth crosses through this cosmic dust. It gets accreted into Earth's atmosphere, increases the opacity of the atmosphere, reflects the sunlight back off, and then that triggers a drop in, radical drop in global temperature.

Now, if you have an impact into land, well, now what happens? Well, impact into land, you're going to eject dust. will inject large amounts of dust into the atmosphere that will circulate around. It'll also produce primary fires at the point of impact. Then the fallback debris will create a whole bunch of secondary fires.
