each one of those gases interacts with light. and some molecules use light. oxygen. we send out into space, life does, but other things do, too. some molecules only life sends out into the atmosphere. and so it s one of the reasons i m so fond of it because although it s rare and actually quite poisonous, only life makes it on earth. and so it s an unequivocal sign of life. my generation, we re betting on the fact that nature delivers, that life can originate and evolve anywhere given the chance. and we re planning on finding it. there s no question. reason, or fun. daring, or thoughtful. sensitive, or strong.
physically, evolution made us, biology made us, but the things of biology were created in stars, the water, the carbon, the nitrogen, the oxygen, all of that was created in stars. people will say, well, if there are ten to the 22 stars out there, there must be more life than just us. however, it turns out the number of coincidences would have to occur for a life to emerge is also a very large number. we have to have a star like our sun that lives at least 10 billion years old. it has to be in exactly the right part of the galaxy to start with. we might need to have a moon. we might need to have geothermal because we need a magnetic field to protect us, and evolution had to happen, and then you keep on going, well, you know, the dinosaurs evolved around for 100, 200 million years, they didn t evolve into anything, and then came and wiped them out,
walked into the line, there s a bit of a line, and she turned around and i asked her would you like to join me for lunch, and she said yes, and we got a table off to the side by ourselves, and, you know, five minutes into that conversation, i knew my life was going to change. i knew something was going to happen. don t let me interrupt you from continuing the telescope. okay. let s get back to this thing. and we ll see what we can i don t really know why anyone wants to know why there s life out there. i guess because we re kind of a lonely species. i think loneliness is a human condition. everyone s sort of trapped in their own head, and we try with
deploy? this is a worldwide telescope. it s the collective investment from the u.s. and the european space agency and the canadian space agency that all these countries are willing to make to reach the edge of the universe. separating from the upper stage, separating from going down two the stakes are tremendous. if you think back to cu curiosity, the seven minutes of terror waiting for it to get to the surface, we all held our breath a long time. waiting for the signal back from the surface. in this case we re going to hold our breaths for air couple weeks because that s how long it s going to take to get all the deployments out after launch. adding whatever delta v we need. there are over, you know, 300 or 400 different operation ts tt have to occur in space to make this telescope come to life.
mineral. you find it as dust throughout intercellar space, this is a common mineral, and the thing is it will react with water, bubbling hydrogen gas out, and that s basically the environment giving rise to life. do you think that there s life out there beyond the earth? i think we hope that there s going to be lots of amazing complex life out there, kind of semihuman in a way that it interacts with us. and i think we re likely to be quite disappoint about that. maybe we should be interacting with life on our own planet in a more meaningful way. how can you push a planet in one direction or the other and still have it capable of sustaining life? during graduate school, i would walk from the astronomy department to family human housing, and we were studying, and my head was full of images
