the earth is not flat and it is not 10,000 years old. so furthermore so this stuff is completely inconsistent with what we observe in nature. that is the concern to spend tax dollars intended for science education to teach a -- what would nominal yir be called with autopsy respect a creation myth, an explanation of things the way they are that's not right. >> so bill you bring up inconsistencies in the theory of creationallism. >> i want to go over the requirements such as these, that students analyze all sides of scientific evidence, they analyze the sudden appearance stays is in the fossil record, the cell and dna model for replicating life. georgia, explain what those things mean and why you think they're important. >> well, i think that the biggest thing, what bill raised, was trying to lump evolution and creation, in with all the other science that -- types of science that we do today. evolution and creation are one time events that have happened in the past. they are not observable testable or repeatable. unlike science that we do

it's jt that the earth is curving under. let me give you a fact that a geography teacher can tell you about. if you go out 8 kilometers, that's 8,000 meters this way, you'll find out there is a five meter vertical drop. you will be 5 meters higher than you were over here. we live in a world that for every 8 kilometers you go out, tangent-wise, there's a 5 meter drop. that's all i'm saying. but that 5 meters turns out to be interesting, because we've learned something about 5 meters, gang, haven't we? what have we learned about 5 meters? let's suppose we take this laser, throw it away and we put a cannon, a cannon, newton's cannon. we'll put it right here and we fire a cannonball. is that cannonball gonna follow that straight, straight path? the answer begins with an n. hc? how come? because it's not beginning with a g. don't understand it very well but we have it a little bit together. what is it called? - gravity. - gravity. gravity is gonna pull which way, up or down? - down. - down. watch. let's suppose i fired the cannon

it's out of the gravity will of earth and into space. the big question is what would you make the tether out of? it has to withstand the weather and the micro media rights zooming around in space. it has to withstand the space junk although maybe by the time we build this we will have a space vacuum that has gotten rid of the space junk or we will have robot's collecting the space junk. it's been suggested it might be made out of the carbon man no tubes but it isn't clear whether they could really be used for something like this. but like i said, every time nasa has a contest the offer money to anyone that can come up with a substance the would be strong enough and light enough to be. so far no one has actually won that full amount. although people are working on that angle. if you have an idea than you should go to the space of a greater conference and see if you can help create the future of space travel. the point is things in the future may not look the way that we expect. we've got like i said 900,000 years to change and develop new

you have the earth itself rotating, moving around the sun. so you need to factor so detailed knowledge of the solar system, about the radiowave acts when it does, solar wind, for instance, will affect the radiowave. you need a model for the solar way. indeed, many, many things just to measure this very simple thing. >> this is where the detective process comes in. you had to weed out a lot of uncertainty to figure out if your even sing something real. >> exactly. so the reason that this was sort of at all interesting to anybody is because of what neal works oncome in part from dark matter and dark energy. existing. physicists almost universally, maybe universally can agree that these things exist. and yet we don't have a very good hold. with a very precise measurement in certain respects but you can look at how quickly galaxies rotate or how much mass must exist in the galaxy and is a quite precisely, because you can look at -- [inaudible] my conception of these are constructs that we don't understand where we understand electrons and protons

, and realize that space shuttle is falling around and around the earth. it's going so fast sideways, by the time it falls a little bit, the earth is curved the same. isaac newton was able to calculate w fast the cannonball would have to go. isaac newton was a genius. you know, there are people on this campus that can calculate how fast the cannonball would have to go. and you know what? there are people in this room who could calculate with no pencil, no paper, only their minds how fast the cannonball would have to go. and i think that 80% of the people in this room can make that calculation if i guide your thinking. can we try it? you want to see who you are? let's try. let me give you a geometrical fact. we live in a world that's curved. we know it's curved because if you put a laser one meter off the ground and you fired the laser beam out over the desert like the mojave desert in california, perfectly flat for miles and miles and miles. if you fed that laser beam, you'd find out the lasebeam over here, it looks likto people it's poiing up but it's not

its purpose: observe stars thousands of light years from earth that may harbor earth-like planets.looking at what happens to the light emanated by the stars, it's discovered more than 3,500 possible planets-- more than 100 of which have been independently confirmed-- but it has not yet found one planet that has the right conditions for sustaining life as here on earth. nasa says the spacecraft's wheels, which are critical for keeping it pointed correctly, do not work anymore. astronomers are now assessing its legacy. michael lemonick is the author of a book about kepler called "mirror earth." he has long written about space and science for "time" magazine. michael lemonick, welcome to the "newshour." tell us a little bit more about what the original mission for the kepler was. >> original mission was to take a census, really, of a group of stars-- an average group of stars, to find out what percentage of them have planets of any kind, and what sizes those planets come in and how far they are from their stars, how the temperature on the surface of those planets would be, if you were

>> like the earth that collapsed? it's not like the tv shows. >> the earth does move and it bumps up and you get a ground fracture but it's not something that opens up and sucks you up into haddes. >> it's not going anywhere. we are going to have a lot of damage, but this myth that california is going to the ocean is not real. >> southern california is moving north. it's coming up from the south to the north. >> you would have to invest the million year cycle, not weeks or years. maybe millions of years from now, part of los angeles will be in the bay area. >> for better or worse. >> yes. >> this is a tough question. >> those other ones weren't tough. >> this is a really easy challenge. are the smaller ones less stress? >> yes. the amount released in small earthquakes is that they are so small in you need many of those. >> i think would you probably have to have maybe hundreds of magnitude earthquakes of 4.7. >> so small earthquakes are not making our lives better in the future? >> not anyway that you can count on. >>

the earth is moving. the sun is moving. on the earth, the waves are beating against the shore. everything which is, is vibration. in order to have a sound, you need a physical object which vibrates, whether it's a cello or a speaker in a radio, you need a medium to carry that vibration. typically, it's air, and finally we need an ear, an ear drum, and a brain to turn it into something that's meaningful to a human being. [flute plays] the simplest sort of sound is called a sine wave, and i can display that sound on an oscilloscope. of course in nature, nothing is so simple as that. there isn't just one sine wave happening at one moment. actually, there are many sine waves all adding and subtracting. when you listen to a sound, when you listen to a musical note, you hear several things. [flute music continues] you hear the basic note, but you also hear some overtones that are generated. (man) the overtone series is really quite simple. behind every acoustically generated tone, there is a series of other tones which are happening simultaneously, and this series of tones extends ab

the asteroid that plays its way into russia may be part of a family that could be flying towards earth. the era of tough sanctions on iran should be buried in the past that's the message from the country's new president hassan rouhani was elected on a platform promising dialogue with the west in an attempt to end the country's isolation over its nuclear energy program but it transpires not everyone is enthusiastic about the reconciliation drive. reports. iran's new president hassan rouhani is widely seen as a moderate politician particularly significant detail where western leaders are concerned after years of strained diplomatic tensions now in what is seen as an attempt by tehran to ease in that isolation the government had sent out invitations to e.u. countries including britain to attend to be a swearing in ceremony. albeit excluding the u.s. and israel now the position was that only tehran a base of diplomats would attend but the u.k. had not sent anyone at all the reason given by the british foreign office is that it does not have an embassy in tehran but this has been criticized

google earth is an incredible resource because from hundreds of miles in space we can zoom in and weind things. everyone always looks for their house first. that is the tip of the iceberg with remote sensing. satellites record data in different parts of the light spectrum that we can't see. it's that information that allows satellites to be so powerful in terms of looking at things like vegetation health. finding different types of geology that may indicate an oil deposit or some kind of mineral deposit that can be mined. i tell my student on day one. a picture is worth a thousand words. a satellite image is worth a million dollars. satellite imagery is from space and allows us to get perspective we don't have otherwise. when you add on top of that the ability to see a little bit differently, all of a sudden you have an amazing scientific tool you can use to answer questions about climate change, environmental change, population change, and social change. >> how many people around the world do what you do? >> there are about 20 to 30 people that are very involved. you see their names

so you have a platform on earth. you have an elevator platform somewhere along the equator and then you have a very very long tether attaching that elevator platform up about 60,000 miles so you are part way to the minute that point. at the other end of the tether you have a counterweight in that counterweight is in geostationary orbit so it's orbiting the earth but also attached by this tether and i will get to the tether in a minute because the tether is kind of the problem. right now we actually have the technology to do a lot of this. a counterweight not so much. the counterweight might be a captured asteroid he might yet happy version of a death star. basically what it's going to be is a port. it's going to be a destination for people to get due in space where they can get onto a spaceship that would take them somewhere else. the space elevators just to get you out of the gravity well into space and then on your merry way. we'll take you about three days to get up to that counterweight or port so that car isn't

[all clamoring] [rumbling] >> buddy, did you feel the earth shake, too?otter and hotter. old smoky looks like it really wants to erupt. >> look! it's--it's-- >> it's erupting! >> whoa! ooh! ahh! >> [squawks] it's spectacular! >> yeah, the most amazing thing i've ever seen. >> bless my scales and feathers! what a magnificent sight! >> the best volcano ever. >> let's hear it for the volcano! >> volcano! volcano! volcano! [all cheering] >> 1, 2, 3, 4, 5 pteranodons, one t-rex, and one troodon. just making sure. >> that's right. the whole family is on the dinosaur train, going one way only--home! [all cheering] home sweet home! >> hi there. i'm dr. scott, the paleontologist, and this is a volcano. >> volcano. >> volcanoes happen when melted rocks deep underground burst through the earth's surface, causing an eruption. after that melted rock erupts out of the earth, we call it lava. >> kaboom! >> now, many volcanoes form cone-shaped mountains like this one, with a huge crater at the top where the lava comes out. once the lava cools off, it looks like this. >>
