. >> dr. tyson. dr. tyson, tonight's question, asteroid mining. bull (bleep) or no bull (bleep)?n, in this case, the answer is no bull (bleep). >> jon: amazing. >> jon, your opening credits still show the earth rotating in the wrong direction. i'm just saying. (laughter) (cheers and applause) so we're writing a whole bunch of different poems at the same time. i'm a writer. i'm a teacher. i'm a poet. when i see somebody's handwriting i have an immediate connection to who that person is. pass! any new technology introduces new forms of expression... this is so cool. ...and that moment of connection is really powerful. ...that's all he's really pleased about. the revolutionary galaxy note... ...from samsung. (cheers and applause) >> jon: welcome back to the show. i don't know if you noticed this, by the way, neil degrasse tyson was holding a rubik's cube. i swear to you that thing was not solved when we gave it to him maybe 25 seconds before he walked out here. (laughter) he's e.t . i believe he is e.t . i think he did one of these. "solve it." (laughter) listen, having spent the fi

(laughter) listen, having spent the first act of tonight's show on asteroid mining-- which i did-- we turn now reluctantly to the 2012 presidential campaign. today stunning new development. >> this just into cnn. we have confirmed that newt gingrich will, indeed, drop out of the presidential race next week. (cheers and applause) >> jon: no, not yay. not yay. (laughter) anyway, he announced he was dropping out next week. (laughter) that is so gingrich. (laughter) "today i am call

but my question for you, dr. tyson is how can we get our o sons and daughters who are so wrapped up in the fruits of technology that they do nothing else? they don't innovate, they don't create, they don't have a passion, they just stay on facebook and ask for another telephone? [laughter] [applause] >> so, so the problem is not that they are looking down in their technology. the problem is that we are not engaged in a project that is grand enough to compel them to look up. [applause] that is the challenge. >> okay. >> can i give you an example? it's a quick -- i said i'd be quick on these, but i'm not being quick. [laughter] do you know what tweet-ups are? in the twitter verse companies or agencies have a launch, and you invite a certain number of people who are active on twitter, and you give lectures to them, and they're tweeting everything. so the twitterverse lens about what's going -- learns about what's going on vicariously. i, at one of the nasa launches, gave a talk to the tweet-up community. and do you know w

dr. neil degrasse tyson who we've had on. >> yeah. >> jimmy: he's a genius. >> great astronomer. >> jimmya giant geek, this guy. >> he is, he is. >> jimmy: he doesn't care. we can say it. >> he said, you think you're such a big perfectionist when rose is lying on the raft in the freezing of the middle of the north atlantic and she looks up and you cut to the sky. at that time of the year, in 1912, at that latitude and longitude, those would not be the stars. [ laughter ] and i was shocked. [ applause ] >> jimmy: it's about time. i mean, yeah. >> wow. >> jimmy: i saw that. it took me right out of the movie. i go, this is fake! [ laughter ] >> i mean, we only made it to 1.8 billion. think what we could have done. if it wasn't for that star field. >> jimmy: neil, where were you when we needed you. >> you don't get too many second chances in life but this is one. and this is actually the reason that we're re-releasing the film. so we could correct. [ laughter ] >> jimmy: but you actually did go back and you fixed it and made it -- >> yeah, we fixed it. >> jimmy: that's what i'm saying. this g

. >>> next, mike tyson. [ dr. rahmany ] introducing crest pro-health clinical rinse.t actually keeps your teeth 91% clean of plaque even at 2 months after a dental visit. new crest pro-health clinical rinse. >> how you doing? >> right on the chin. i'm going to relax. i don't want my head to swell anymore than it is. >> mike tyson at the start of his career, in a documentary "tyson." a lot has happened since then. he was certainly no choir boy. now he's fought his way back from the dark side, but he's still the outspoken and unpredictable iron micro ke and he joins me now. >> how you doing, piers? >> what did you make of the interview i just had with george zimmerman's brother? >> i don't know. i wasn't there. i don't know what happened. i have a good opinion what happened, like everyone else. i don't know. he doesn't look like a seasoned enough liar to talk to you. >> what do you think happened? from everything you've seen and read? >> i don't know what happened. >> do you believe that any kind of altercation, if trayvon was unarmed, justifies somebody shooting him? >

. >> thompson: the autopsy on tyson's infant son was performed by dr. paul shrode. he found the case a homicide based on blunt force trauma to the head. but that's not what the forensic pathologist for the defense found. >> looking at the kind of force you need to create that kind of injury to the brain-- there was no skull fracture, there was no other inry to the brain any other location. so it seemed to her that the injury described as blunt force trauma really didn't exist. >> thompson: in the end, the defense expert argued jayceon died of an infection. she also testified that some of the bruises dr. shrode saw as signs of abuse were likely birthmarks. the defense attorneys made a point of dr. shrode's lack of board certification, and challenged his truthfulness. >> he had falsified his résumé in the first place. we had also discovered that he was involved in another capital case where a man was apparently on death row, due in large part to dr. shrode's testimony and his findings in another autopsy, which were apparently debunked, unfounded. >> thompson: dr. shro

you get a lot of this going on. >> dr. tyson, the big expensive space i believe is getting local service to big rockets which is really parallel to technology. as they have been looking seriously at antigravity, just like in the early h.g. wells, earth to the moon or whatever. >> good question. among the propulsion research that is going on it does not include antigravity. and the ground is a pretty remote notion passionate anti-ground -- you don't find people who are physics fluent ready to devote their lives on antigravity. the people attended antigravity our people who think that laws of physics are only guidelines rather than laws. [laughter] these are the same communities who would do, for example, perpetual motion machines but it violates known and tested laws of physics. so okay, maybe you'll succeed, but i'm so confident you won't that i'm just going to go about my way. so don't expect a lot of money to be devoted to antigravity devices. but nontheless, there are other challenges of propulsion. there's the ion drives, an
