scientists simulate the composition and conditions of different atmospheres and observe how they react to ionizing particles. what you see that silver cylinder down there. it s actually the thermal housing that surrounds the cloud chip the chamber itself this three meter chamber is inside of it it s a very special chamber because it s the cleanest chamber in the world in fact it s the only chamber where we can do these experiments. the chamber has to remain absolutely sterile in order to carry out experiments with gas mixtures the slightest impurities could cause problems. now the importance of the particle beam is that it provides some adjustable source of cosmic rays if you were to do these experiments in the atmosphere you would have no control over the cosmic rays the to passing through. we re not allowed to enter the
the debris, but the odds of it actually hitting you, we took this a step further. that s one in several trillion, trillion with a t. chad myers, so the news today, we are now in the strike zone. is that for now or for good? that will be for good, until it falls out of the sky and we ll know. we were doing this little tweet thing back and forth a little bit ago about how the earth is not round. the earth is not round. it s fatter at the equator. so this thing will be closer to the atmosphere every time it passes the equator. every time it goes around the earth, it will start to drag. at one of those times it s going to get a little too close, touch the atmosphere, start to turn, burn up and that s when it s going to slow down enough to make the fall. there are several passes. i can show you coming up here. let me take you over to the wall here as well. we have kind of a different little plan here. the map as it s coming in right now, it s coming up and just to the south of a
