0:11It’s a great honor todayto share with youThe Digital Universe,which was created for humanityto really see where we arein the universe.And so I think we can roll the video that we have.
0:31The flat horizon that we’ve evolved withhas been a metaphor for theinfinite: unbounded resourcesand unlimited capacityfor disposal of waste.It wasn’t until we reallyleft Earth,got above the atmosphereand had seen the horizonbend back on itself,that we could understand our planetas a limited condition.The Digital Universe Atlashas been builtat the American Museum of Natural Historyover the past 12 years.We maintain that,put that togetheras a projectto really chart the universeacross all scales.What we see here are satellites around the Earthand the Earth in proper registrationagainst the universe, as we see.NASA supported this work12 years agoas part of the rebuildingof the Hayden Planetariumso that we would share this with the world.
1:50The Digital Universe is the basisof our space show productions that we do —our main space shows in the dome.But what you see hereis the result of, actually, internshipsthat we hosted with Linkoping Universityin Sweden.I’ve had 12 students work on thisfor their graduate work,and the result has been this software called Univiewand a company called SCISS in Sweden.This softwareallows interactive use,so this actual flight pathand movie that we see herewas actually flown live.I captured this live from my laptopin a cafe called Earth Matterson the Lower East Side of Manhattan, where I live,and it was doneas a collaborative projectwith the Rubin Museum of Himalayan Artfor an exhibiton comparative cosmology.
2:52And so as we move out,we see continuously from our planetall the way out into the realm of galaxies, as we see here,light-travel time, giving you a sense of how far away we are.As we move out,the light from these distant galaxieshave taken so long,we’re essentially backing up into the past.We back so far upwe’re finally seeing a containment around us —the afterglow of the Big Bang.This is the WMAPmicrowave backgroundthat we see.We’ll fly outside it here, just to see this sort of containment.If we were outside this,it would almost be meaningless, in the sense as before time.But this our containment of the visible universe.We know the universe is bigger than that which we can see.
3:40Coming back quickly,we see here the radio sphere that we jumped out of in the beginning,but these are positions,the latest positions of exoplanetsthat we’ve mapped,and our sun here, obviously, with our own solar system.What you’re going to see — we’re going to have to jump in here pretty quicklybetween several orders of magnitudeto get down to where we see the solar system —these are the paths ofVoyager 1, Voyager 2, Pioneer 11 and Pioneer 10,the first four spacecraft to have left the solar system.Coming in closer,picking up Earth,orbit of the Moon, and we see the Earth.This map can be updated,and we can add in new data.
4:31I know Dr. Carolyn Porco is the camera P.I.for the Cassini mission.But here we see the complex trajectoryof the Cassini missioncolor coded for different mission phases,ingeniously developed so that45 encounters with the largest moon, Titan,which is larger that the planet Mercury,diverts the orbit into different parts of mission phase.
4:52This software allows us to come closeand look at parts of this.This software can also be networked between domes.We have a growing user base of this,and we network domes.And we can network between domes and classrooms.We’re actually sharing tours of the universewith the first sub-Saharanplanetarium in Ghanaas well asnew libraries that have been builtin the ghettos in Columbiaand a high schoolin Cambodia.And the Cambodians haveactually controlled the Hayden Planetarium from their high school.
5:31This is an image from Saturday,photographed by the Aqua satellite, but through the Uniview software.So you’re seeing the edge of the Earth.This is Nepal.This is, in fact, right here is the valley of Lhasa,right here in Tibet.But we can see the hazefrom fires and so forth in the Ganges valleydown below in India.This is Nepal and Tibet.
5:56And just in closing,I’d just like to say this beautiful world that we live on —here we see a bit of the snowthat some of you may have had to brave in coming out —so I’d like to just saythat what the world needs nowis a sense of being able tolook at ourselves in this much larger condition nowand a much larger sense of what home is.Because our home is the universe,and we are the universe, essentially.We carry that in us.And to be able to see our contextin this larger sense at all scaleshelps us all, I think, in understandingwhere we are and who we are in the universe.
