*long pause*
Humans are imperfect. So, I made this series and I started this series prior
to the protests about George Floyd and the
hundreds of other black Americans that have been killed by police brutality
began Black Americans have been experiencing something for their entire
lives and their parents lives and their grandparents lives and a lot of people
are just waking up to it and I hope they stay awake and I hope that moments like
these hit our national consciousness in a way that we remember I believe that
black lives matter and I believe that what is happening now is just the match
that starts a fire and I hope that fire doesn't go out because we need it we
need to burn away the things that are antithetical to our values all people
are created equal all of them we just don't treat them that way and we should
I don't know how to properly transition from what's going on in the world to
what's going on here on my channel but our goal should be to better understand
each other and where we're coming from not to ignore or diminish each other
that's not what we're about I have put down in the description a few
different places where you can find more information and learn how to be better I
know I'm learning and it is a process that we will be learning for quite some
time but we can do it together we can do it together follow the black
and stem hashtags follow black and stem on Twitter let's elevate voices that
need to be heard I really do hope that you enjoy the series there may be some
people who think Oh leaving Earth I would like to do that right now so
hopefully that speaks to you is well even even though that was not the intent
I started putting this together thanks again for being a subscriber for
watching you know dose of tres
yo space is dangerous people have died getting there and getting home and even
while in space space is harsh it degrades our bodies and it corrupts the
building blocks of life it even makes simple tasks that you and I can do here
on earth difficult space is beautiful achievements in space are celebrated by
all of us everywhere in the world the vastness and variety of space promises
an eternity of exploration space is the future we cannot live on this planet
forever we simply cannot zoom out in our
timeline as far as you want and at some point we either have to leave or we die
here we have to go to space we have to become multiplanetary
we have to leave Earth but how do we do that I got you fam one of the oldest
films our species created was based on an even older story it's considered the
first sci-fi film it's called lavash de la lune humans build a giant cannon and
they shoot explorers to the lunar surface it's pretty awesome film if you
haven't seen it's not very long and it was created in 1902 space habitation has
been imagined by humanity since the mid to late 1800s in 1903 author constant
until coughs key created this idea of a rotating space station that would
generate its own gravity we've had ideas like solar energy greenhouses for food
this was all from him over a hundred years ago we wanted to leave this planet
for so long and the question isn't if we leave but when we leave and how right so
unless you're in the Y camp you know why would we leave if you're there let's you
know bring you out of it the simplest answer of why we should leave is that
all birds leave the nest in 1883 Krakatoa in Indonesia
erupted it actually erupted might not even be the right word it exploded with
the fire of a thousand health thirteen thousand times larger than the Hiroshima
bomb it was heard five thousand kilometers away in Australia shockwaves
from this explosion circled the planet seven times everything on the island was
destroyed everything there were no plants no insects nothing because there
were other islands around Krakatoa though species were able to catch the
wind and return to the island just a few years after this explosion that
decimated everything not decimated actually zero made it I don't know what
everything is just completely made all life extinct on that island small plants
insects and trees had all come back several years later medium sized animals
started to return fifty years after this giant volcanic explosion there were
hundreds of species on the island and that is because they had little
lifeboats life was elsewhere and it could repopulate super volcanic
activity like this could happen worldwide eventually or an asteroid
could hit us again 99% of all species on the planet are already extinct actually
99.9% there are a multitude of reasons to leave our planet but here are a
couple of my favorites our Sun is 4.6 billion years old it's a main-sequence
star and it's gonna flame out in a few billion years earth will boil and go
bye-bye if we don't have volcanoes or asteroids destroying the planet the core
could cool enough to lose our magnetic field we could just destroy ourselves
with climate change we are all on the same island right now if there is a
disaster we all die and there's no one to carry
on or repopulate if some of us are somewhere else our species our life on
this planet could live another reason why I think we should explore space
aside from just satisfying this emotional curiosity that humans have is
that the problems that you come up with in space the problems that you come up
against survival in small groups conflict resolution understanding how
resources need to be managed all of that so you live in space but can be brought
back and used to make the earth better for example using energy that is
renewable getting energy from the Sun that the Sun
is just throwing off constantly that solar energy has been powering the
International Space Station and that has happened completely off of the grid and
that is possible because of the technological advances that were made in
order to create it and we can bring that technology back here to the earth and
make earth cleaner and better and better support all of the people that live here
so we should leave earth because in the challenge of leaving this cradle of our
humanity we will make the cradle better that's my favorite reason for leaving
sure asteroids the sun's gonna explode the heat death of the universe is
inevitable no matter where we go we can't run from that but we can't sit in
the cradle because that's comfortable we have to eventually go in 1975 there was
stuff on the moon we left golf clubs and poop and retroreflectors and lunar cars
and those visits changed the world it made people think differently about our
tiny little teeny planet here sci-fi author and biochemist Isaac Asimov and
physicist Gerard O'Neill sat on the couch in a 1975 episode of PBS
roundtable and he talked about creating habitable cities in space I've got out
the full enormity of the plan that you have in mind how many people would this
one whole mod one the very first one mr. Hayes might be 10,000 people there might
be four little villages at perhaps 2,500 people in each it's the total population
being perhaps 10,000 people I see how do these people live within this cylinder
well they would be they would be growing crops by normal agriculture although
quite intensively because of the fact that the weather would be controllable
and the length of the day would be controllable since droughts rollable no
insect pests we called the Earth's the old country
that was in 1975 it's been 45 years since then the plan was then to
establish a moon base and mine the moon for materials to use 70s technology to
lift materials to Lagrange points which are different gravitational parking
spots around the Moon and Earth and at those spots you could put something that
just hangs in space and it doesn't move relative to the earth in the moon it
appears to be stationary and you could live there obviously you know didn't do
that it's amazing that we went to the moon 45 years ago and we are still
talking about it today all the time while researching this episode I watched
a show called return to the moon and it said that the moon is filled with
resources we could think of it as basically the 8th continent so cool
right this show is only on curiosity stream
they helped sponsor this video so thanks to them
we've been pandemic in for like a while now and during this time curiosity
stream wants to keep your brain engaged which I fully identify with there are so
many different shows that you can do that with on curiosity stream like the
art of the heist which is about high profile art thievery or how the internet
changed the world with Bay Derek Muller curiosity stream is fact-based
escapes from the norm which I love I still want to be more entertained but I
want it to be truthful if you use the link on the screen or down in the
description you're gonna get curiosity stream plus you're gonna get nebula
nebula is a brand new streaming service that I started with a bunch of other
creators and we've put all of our content there for you we wanted a place
that if you join you would support us directly and you'd get to see videos
from thoughtful and smart and fun creators that we all love we even get to
pool resources to create our own originals and try really cool things
like the history of synths or breaking down our favorite title sequences or
exploring the history of World War two we've done a lot on nebula and there's
gonna be so much more so you should join so recap get curiosity stream you get
that annual subscription at only $2.99 a month and you get big-budget nonfiction
plus if you use my code you get a free month to start and as long as you have
curiosity stream you get nebula for free - which supports us creators directly
just visit curiosity stream dot-com slash trace use that promo code trace
you're gonna get nebula and curiosities together so you can stay home and stay
curious but you know let's go back to the moon mining the moon is still a
thing we're still interested in that we've got moon rocks they're made of
similar stuff to the rocks here on earth but they have more titanium in them
they're actually 10 times more titanium than Earth and refining those materials
requires a vacuum and on earth we'd have to build a big room and suck all the air
out of it but on the moon we can just mine it sorry in a vacuum
the moon has iron and oxygen chlorine and lithium beryllium zirconium uranium
thorium rare earth elements used for electronics it even has water and
helium-3 a super rare form of helium that's very useful and that's not the
only place that we can leave to there are asteroids we could live on an
asteroid some are ice some are collections of pebbles and rocks some
have water or iron or other rarer minerals we could hollow them out live
on the inside we could make them into mines and bring the resources back
spaceflight feels easy it feels safe and we're really good at it but it ain't
safe or easy and we're actually not that great at it
last weekend amidst widespread unrest across the United States humans launched
into space on a private space vehicle the first time that had ever happened
sidebar black lives matter now I say we're bad at space because it took us
nine years to make that happen after the space shuttles were retired we only ever
built six space shuttles and they cost so much money 450 million dollars every
single time we launched one and if you want to leave earth we're gonna need to
do better need to make it easy and cheap to do and again why maybe you're still
asking let me reframe this for you many of us around the world are sequestered
in our homes feeling that itch to go outside to go on a balcony or in a yard
to go to the stoop or the street and just get outside a little bit right just
a taste to that outside world think of it this way
the International Space Station is our balcony our stoop the moon is our
backyard we smelled the air in the 1960s and 70s we saw the horizon and we cannot
stay inside forever we must eventually go into the yard go
out and explore so if we want to leave we want to grab these minerals to build
our multiplanetary species if we want to figure out how to better explore the
universe how do we do it how do we leave this whole series is gonna dig deep into
how we do all of these different things because let's face it we got to do it so
stick around so you get all the episodes in this series we can figure out how
we're gonna leave where we should live and how we're gonna get to another star
so again stick around subscribe and I will see you in the future
