i'm a huge carl sagan fan.credible way of just like reminding us how insignificant we are, but how significant this opportunity to live this life on this planet could be. i know currently right now there's like -- i know that like climate change is not real. it's not real. >> jimmy: the chinese made it up. >> yeah, it's a hoax. if we're going off of what our administration says. >> jimmy: right. >> right. so like for me, like you know, that guy just -- i like everything that he had to say. and so my team, they know that. and they also know that like when i make a request, as much as i could say i'm the boss, it's them that actually has to do it and deliver it. >> jimmy: right. >> so when i say, please stop doing that, they just continue to do it. [ laughter ] >> jimmy: just to bust your balls? >> yeah. >> jimmy: you're running a tight ship there. that's what we did in your dressing room. [ laughter ] there's a photo of carl sagan along with the snacks. >> yes. [ applause ] >> jimmy: why did it take you and n.e.

carl sagan wanted a way of traveling quickly through space and this led to the movie interstellar. in the 50s wheeler had another student who questioned another aspect of quantum physics on a fundamental level, when you take a navy -- a measurement in quantum physics the observer affects the measurement because as soon as the observation is taken if there are two different possibilities, the system is said to collapse to one of the two possibilities. hugh everett thought that was ridiculous. how could a human observer affects a quantum measurement? this man being inspired by a talk einstein gave to everett and others where he joked if a human can make an observation why not a mouse? why do you need to have a human? everett thought deeply about this and went neil deboer visited princeton, brought this up, he wouldn't hear of it, he thought the idea of human observers affecting things was fine, the theory works, why tamper with it? everett came up with an idea that instead of involving the observer, when you take a measurement, the universe would split into one of the two possibiliti

. >> i grew up in mexico, and i was very young, i watched carl sagan's "cosmos," as probably every otherld in my generation. that inspired me to study the stars, to work on things that leave the earth. >> reporter: paulo losano is the director of the space propulsion lab at the massachusetts institute of technology. he's found a solution to the cubesat problem, and the idea fueling his cubesat mini-rocket is simpler than you might think. >> what we can do is to rub the plastic on any fabric, really, and you can put a little bit of liquid on your finger and then get it close, and you will see, the liquid flying, producing a little cone and then flying to the plastic. >> reporter: that's static electricity, and it's not just tugging at the droplet. look more closely and you'll see the static creates a spray of charged molecules called ions. lozano's tiny rockets, which are the size of quarters, generate these ion sprays. >> they don't produce a lot of force. so it's always less than a millinewton. that's about the weight of a mosquito. >> reporter: this may sound wimpy, but even a small ac

it wasn't until 1983, next 20 years after i was working that scientists discovered including carl sagan and turco and seven or eight people could have come together at the same time , but the firestorms would cause there to be smoke and soot from the burning cities to be lofted into the stratosphere and asked must have happened in tokyo. that was one city at a time. but if you have several hundred cities burning at the same time, the firestorms, the smoke wafted into the stratosphere will not rain out. it will go around the globe fast within days and absorb 70 percent of the sunlight. at first in 1983 a thought that would be about a year. the year was on their computer programs could go to . but that would be enough to start nearly everyone. and sagan at that time said extinction was possible. but it's turned out now in the last 10 years and other people cast doubt on this, the same people .climate change. i hand full of people compared to other scientists but they say it's not nuclear winter, it's just nuclear autumn and it won't be that bad, there were real uncertainties . the uncerta

which is originally motivated by carl sagan book contacts.and this later led to the movie interstellar. in the 50s , wheeler had another student, hugh everett. who questioned another aspect of quantum physics on a fundamental level. we take a measurement in quantum physics, the observer affects the measurement because as soon as the observation is taken, if there are two different possibilities, the system is said to collapse into one of the two possibilities. and hugh everett thought that was ridiculous. how could a human observer affect the quantum measurement? this may have been inspired by a talk that einstein gave to everett and others when he joked that if a human can make an observation, why not a mouse about why do you need to have a human? i never thought deeply about this. and visited princeton, he brought this up. but bohr would not hear of it. at the idea of human observers affecting things was fine. they thought the theory works, why tamper with it? everett came up with an idea that instead of involving observer, when you take a
