00:00Increase the rate of time to thousands of years per second.
00:17And taking us along for the ride.
00:21By feeding Gaia's data into computer models, scientists can simulate the past, present, and future.
00:45The outer part of the solar system that we call the Oort Cloud.
00:50It's this leftover debris from when the solar system formed.
00:55Lots and lots, millions and millions of comets.
00:58Maybe even some asteroids that are out there.
01:01And what we were going to show is dynamic interactions that might happen between our Oort Cloud and other stars' Oort Clouds.
01:10As everything is in motion and stars pass by each other.
01:13Now, as we were modeling the Oort Cloud, we turned to one of the world's leading experts on modeling it.
01:22His name is David Nisvorni.
01:24He gave us his simulation.
01:26And we were looking at it inside of the planetarium just to get an idea of how to make it beautiful for the show.
01:32And we played with how bright all the particles were.
01:35And we immediately saw something that we had never seen before.
01:40That no one had ever seen before.
01:43It was a spiral structure in this Oort Cloud.
01:48Now, this Oort Cloud is a simulation of what we think it looks like.
01:52But it's based on real data of objects we have measured in the outer part of our solar system.
01:59So, when we saw it, we were blown away.
02:02It was a spiral shape, almost looking like a galaxy itself.
02:08But it's shaped by the forces of the galaxy itself.
02:13Of what we call the tidal force of the galaxy.
02:17So, this spiral structure was brand new.
02:22And we immediately wrote up a paper for an astrophysical journal.
02:27And it's now a published part of astronomers' knowledge of what the outer part of our solar system looks like.
02:37And it all came from visualizing data for the American Museum of Natural History's new space show, Encounters in the Milky Way.
02:44I'm Pedro Pascal.
02:47Join me on a journey, through our tight-knit, stellar neighborhood, into the bustling metropolis of the Milky Way.
02:58We'll witness some of the chance encounters that have shaped the destiny of our Sun.
03:04And maybe even the course of life in the cosmos.
03:08On our travels, we can expect to pass through bubbles, again and again.
03:16Because the galaxy is peppered with massive stars that go out in a blaze.
03:21We're all in a journey around the Milky Way galaxy.
03:22And you can still see the next galaxy are in a blaze.
03:23So, here's the galaxy, and this is the galaxy, and this is the galaxy, and this is the galaxy.
03:24y deslizando de deslizando de shockwaves.
03:44Aunque cada pasada de un camino es unico,
03:46todos estamos en un viaje en la galaxia del milky way.
03:50Para nosotros, para nuestro sistema solar y el sol,
03:57una órbita va a necesitar 230 millones de años para completar.
04:03¿Ves el Big Dipper?
04:07Veamos mientras aumentamos la cantidad de tiempo a miles de años.
04:20Conocer a la tecnología, los científicos pueden simular el pasado, el presente y el futuro de nuestra 200 millones de años.
04:40Algunos clústeres miran a una gran estructura, 1000 años de luz.
04:49Es un deslizamiento dentro de las luces de gas y deslizamiento.
04:56Nos llamamos la local bubble.
05:04Nuestro sistema solar está ahora dentro del deslizamiento.
05:11Esto es por lo que los científicos de las luces de las luces de las luces de las luces de las luces.
05:18Gracias por ver el video.
05:25La cuestión es que es un combiante de la notación que estamos viendo reales ciencias,
05:50Pero we're putting that together
05:52In ways with the explanation
05:54Seeing how things
05:56Behave at these vast scales
05:58Seeing our, again, our relationship
06:01To it
06:02And we have to keep that thread
06:04And then
06:06Drawing that together
06:07As, you know, a pacing and a story
06:11That's really told within
06:12A limited time
06:13We put the music score to it
06:16And Robert's music, as I say
06:18Really gives it wings
06:20And that, in the end
06:22The show aspect
06:23Is something that you feel here
06:26At best, if we can pull that off
06:42The stars
06:43We say they're beautiful
06:45We say the flowers are beautiful
06:48Or a landscape
06:49Why that's beautiful
06:51Is because I think we do react
06:54To it on a level
06:55That's emotional
06:58And it reminds us
07:00Of our place
07:02In a much grander realm
07:04And the stars, ultimately so
07:06I mean, for so much
07:08Of human existence
07:09We didn't know
07:10Whether they might just be
07:11Ten feet above our heads
07:12But there's something
07:16That echoes
07:18The periodicity of the sky
07:20And, you know, it was
07:22Our notion of a clock
07:23Is based on our diurnal
07:25Repetitive nature
07:27And all this
07:28But you look at the stars
07:29You're looking at light
07:32It's coming to you
07:33The sun is too bright
07:34To look at
07:35But there's something
07:37Almost hinting at
07:38That these are other suns
07:40Perhaps
07:40And then that light
07:43That links us
07:44When we figured out
07:47That that's traveling
07:48At a set amount of time
07:49You can look at the
07:52You can look out
07:54At the stars
07:55And you're looking back
07:56Into time
07:57And you're looking back
07:58Into the times of lives
08:00You're looking at light
08:01That's arriving
08:02From different epochs
08:04And different periods
08:05And you can say
08:06You know
08:07A deceased relative
08:09Or what have you
08:10You're seeing light
08:11That really
08:12Is still part
08:13Of their time
08:15That's where it gets
08:20Kind of spiritual
08:21And, you know
08:24And that's real
08:27And that's, you know
08:29Is what
08:30I think
08:31Holds us together
08:33Really
