I think we need to unite as a planet and stop fighting each other, we can all achieve so much if we shared and thought about the greater good. Greed, unfortunately holds us back.
I agree. I think that we really need to grow up. We are a young species so there is still left to discover. We can't be intelligent if we keep fighting each other.
i agree as well, this world has been corupted by too much polatics, greed and war. but its all delaying our chances to leave our world. we must act now before its too far late for us all.
10 Billion is the limit for human animals, but human innovation can overcome this. With functioning systems, we could probably comfortably fit 10 billion in a city.
Also economics factor heavily into this. The current market economic paradigm is incredibly wasteful for what we get out of it. We might be ably to switch to another model or at least adapt it enough to fit the future.
Why do you think we have that ability? We aren't even able to avoid the worst effects of global warming, and that is happening right now. As a species, we lack the willpower to survive.
The sooner we leave the better. Imagine all the problems with living on Mars. We humans aren't adapted to that environment; however, over the span of generations, we might engage in artificial selection of our own genes to bridge that gap. Given that it'll take decades to complete such a monumental project, we ought to begin immediately. Even if the initial settlers die shortly upon arrival, the observations that come with making such a harrowing trek would be invaluable.
THANK YOU SO MUCH FOR PUTTING YOUR CONTENT ON SOUNDCLOUD THIS MADE MY MORNING! The Dnews community has been asking for over a year now and it's so nice to see you pay attention to us. I'm going to check it out now thank so much Trace!!!
More than just doing a series on population, may a I suggest a series on resource management and distribution. Effective yield vs use of out current natural resources. In addition to production efficiency and distribution of production around the world. Who controls, manufactures, and controls the distribution of most critical resources for our current systems of consumption. Everything from rare metals to agricultural production to distribution. Technology that is being developed to effectively multiply both diversity and distribution. The security of our food source and political control behind it.. Fresh water conflicts to food biological diversity...
Yes!!!!! I took an advanced environmental class and these were some off the main things to take away from it large population = not enough reasorces = no population
It's pointless because the goals are for humans to inhabit another planet before the "deadline" which is Earth inevitable destruction. So moving into another planet with possibly a longer lifespan than our dear Earth is the logical investment to make.
Turtle This is all just off the top of my head but it just seems like it would be easier and cheaper to apply these terraforming and other technologies to continue living on earth. More as a mid - term goal along with the long - term of going to other planets
Octopus Wilson Who knows? We have many threats facing the Earth such as global warming, overpopulation, the sun evaporating water, or it is possible tides will rise so high it'll consume the lands. Terraforming may be able to at least increase the time we have till evacuation of Earth but can it really prevent Earth's inevitable expiration.
I had a question. if you put a turbine in space, and started to spin it wouldn't it spin infinitely since there is nothing to stop it in space therefore giving up infinitive energy? if so, why don't we do this already?
Awesome points!! How about a series on the effects of the spartan existence that space travel would likely actually require? Maybe a little digging on the evolution point mentioned in the video. Space travel is done by: 1 telepresence (robotics); 2 Spartan manned missions; 3 genetic modification, tailoring the human to the enviro. I imagine the future will be a spectacular blend of all three!! Either way- the stepping stones to these sciences will be found on the moon. Exciting times indeed! Great show!!
So if we do eventually move to a new solar system wouldn't we need to create a new calendar? Because I'm pretty sure that would create A LOT of problems.
Tau Ceti is about 11 light years away and has 2 planets in the habitable zone. I would go, it's been my dream my entire life! As for Mars we should set up airlocks in the caves or magmatubes for easy shelter. It would protect us from radiation, dust storms, and harsh temperatures. Plus it's be cheaper and you'd need less resources to do it.
It is certainly something that will present an enormous challenge between now and the years to come but it's not impossible. We have the technology, manpower and scientific intelligence to successfully figure something out. Certainly it will take an enormous amount of human cooperation as well as a enormous amount of cooperation from every world country to create an effective strategy. Deep space exploration has to be the next step for the human race.

+Mats Mokkenstorm if we become an interplanetary planet, there's a few ways it could go. either we all go by earth time, or we separately go by our living planets time and then we have a different time for space, maybe space time goes by earth time as a sort of commendation to our original planet
Your weird do you really think when the sun expands your going to survive. Do you think you would survive if the earth orbit sifted to the kuiper belt or close to it. And yes I don't fully grasp thermodynamics please update me always willing to learn
Hello Trace, your entire discussion assumes the human race will exist long enough to develop interstellar travel. And, considering the Sun has several more billion years of existence before exhausting its life sustaining energies, it is absolutely nonsensical to make it part of the discussion for humanity leaving Earth. There is great doubt that humankind will even exist in only a few hundred thousand years from now. It's not just the ability to travel among the stars in a space ark, but it would also necessitate the ability to travel at the speed of light, or greater. Also, who would be among the chosen few to seek out brave new worlds, to boldly go where no one has gone before, as far as we know? Would there be a national and world wide lottery? Would the average citizen even be included, or just the elite scientist and their ilk? Who gets left behind to face the Earth's end? Or deemed unworthy to spread his or her seed in space? Should the day ever come, it will not be a pretty picture. And, who says humanity is worth saving? Who would welcome a species that murders it's own members, hates, and discriminates against its own kind? We first need to evolve intellectually, and away from superstitions and false beliefs. Only then will we as a species survive, and have a chance for our star trek across the Universe.
Exactly what I was thinking, there are so many problems before adopting to a new environment. How will we get there, who will fund it, who will go, and if we ever leave, will we have enough fuel to keep going without running out. It is pretty unlikely that we will find a solution in our life time even before we go.
Not that I have any special knowledge on the subject, but I am certain humanity will not exist in 7 billion years. We will most likely cease to exist as a species in just I million years or far, far less. If, we are to develop the technology for interstellar travel, it will likely be in the next I to 2 hundred years. But, that is predicated upon the fact that we don't destroy ourselves and the Earth, which is the more likely outcome.
I agree. I think that we really need to grow up. We are a young species so there is still left to discover. We can't be intelligent if we keep fighting each other.
I'm excited about Terraforming episode! It has always fascinated me ever since I learned what it meant when I played Master of Orion 2 game when I was a kid. How could life terraform an inhospitable planet to suit its needs? Interesting stuff.
Yes please do a series about overpopulation Trace!!! I find that topic to be very interesting and scary. I feel like overpopulation doesn't get talked about enough.
one of the most exciting things about thinking of colonizing another planet is the thought of another planet with life already on it. What kind of strange alien animals might we find or will they really be that different from what's on earth.
I would go in a heart beat, promise, the opportunity to go cultivate another solar system and planet, that would be extraordinary and would make an amazing adventure.
The most important reason is why we should leave earth. Is that earth is the single point of failure. We have to spread humanity across the universe or we will be wiped out if something happens to earth.
Traces wrong about the Goldilocks zone requiring that a planet has liquid water as opposed to frozen water. If we have a plentiful energy source, we can go to any planet that has frozen water. We can heat up the water and turn it into liquid water for our purposes. I'm not saying that this would be comfortable, but a habitable planet that is uncomfortable is better than no habitable planet at all
I'm not advocating that caves be built on every planet that would otherwise be uninhabitable. Venus's atmosphere must be blown away with many nuclear blasts before Venus can be considered a candidate for habitation. All I am trying to do is expand the number of candidates available for human habitation. An uncomfortable but habitable planet is better than no planet at all.
If we live in other places of the Earth, it will be like 500 years ago. It will take years to get messages to other planets if they are in other solar systems. I really like these series also and hope to study something in this feild in College (im 13 though)
I would argue that consumer vs producer is based off point of view. From the point of view of a plant, animals are a producer because they create CO2 and fertilizer for it to consume.
To correct you: You said that Mars isn't big enough to hold onto an atmosphere, but that's not true at all. Case in point, pluto has an atmosphere similar to Earth that's 80% nitrogen and it's smaller than Earth's moon. Clearly size isn't the important factor here. In fact, based on this and the composition of Earth's moon, it's actually possible that Earth's moon had an atmosphere before tidal locking kicked in this preventing any additional heat from being added to it's core. Once the magnetic field shut down, if any atmosphere did ever form, it would have been stripped away very quickly. The reason why Mars doesn't have an atmosphere, and pluto does, despite both lacking a magnetic field, is that mars is closer to the sun and more exposed to solar winds.
Man so many questions. Would we be able to move every one? Will we even live long enough to see this day? Will in this *future civilization charted by Earthlings* Forget about earth and study its changes (Make trips back to Earth and the planets in our solar system) ? In how many years *Estimate* will it be possible to even make technology that can get us from Earth to unknown? If we chose to move In what solar system might it be? I have many more but if you have any thoughts please leave them down below
My best bet is going to Mars followed by Ganymede. These two worlds are quite fit for terraforming. I know Ganymede is quite far away, but once there, we'll have enough to cherish ourselves. Then, we should think of moving Venus away from Sun to cool it down to reasonable levels. Sky city on hot venus is not a good idea.
I read something recently in regards to an expected 'Population Implosion' as a result of an aging population, which in turn is a result of the same excessive breeding that has caused this popular belief that we're headed for a situation with an overpopulation. A Population Implosion would most likely lead to the opposite, underpopulation and difficulties maintaining a population capable of both breeding and maintaining societal needs. It would be very interesting if you did a series on both of these potential scenario and comparing them.
With the rapid development in the fields of biology, it sounds like it'd be easier to genetically engineer humans to suit a potential new planet than it would to try and adapt it to suit us.
Awesome series, thanks guys! I think a series on overpopulation and ways in which we can deal with the coming 'major' issues our civilization will face in the next few decades is a great idea!!
We could also alter our DNA to allow us to survive on different planets. Terraforming and changing an atmosphere will take too long, so why not change ourselves instead.
2:30 FYI, we reached "Peak Child" about a decade ago. Population will peak in a about a century on 9 billion, (as babies just born reach 100-year old life expectancy) After that population will go down. Watch "Don't Panic" by prof. Hans Rosling (RIP) for a better explanation.
i know DNews+ is busy enough on youtube, but have you been uploading on to itunes because i can't see any new episodes since your one about monsters. If not, why? DNews+ is a great thing to listen to during commutes and I miss being able to. But that being said, great show!
He said, (on the counter 15:59) Mars is not big enough to have atmosphere, but why does Titan, in spite of being smaller than Mars, have an atmosphere more dense than Earth's?? Yes, Mars does not have a magnetic field to sustain one, but Titan just debunked his statement of being too small.
i personally am so in love with our beautiful precious planet and all the amazing creatures and plants and life that i would never leave her....not unless it was my sole mission to create a sort of space "ARK" so that not just humans could leave earth, but all manner of flora and fauna was being collected and saved as well....all life deserves a chance, even if its not directly "useful" to humans, and we are responsible for all life on this planet at this point. it would be fascinating to see how over thousands of years not just humans evolve in space, but many many other life forms as well!
I believe in the “dirty garbage theory of life on earth”. In the ancient past, a spaceship stopped on earth. Opened the door and looked out. They said, “Nope, nothing here.” Dropped there trash and flew off............ NOW, here we are!
One possibility totally overlooked in your video is building sustainable space colonies. Instead of looking for a perfect place to live, why not build one? Certainly difficult, but nothing fundamentally impossible about it. Plus a space colony can be moved over time to avoid long term hazards, unlike a planet. In addition humans should strive to live outside of gravity well instead of being trapped in one, as it provides vastly greater mobility.
Great show as aver Trace, but can i say, please remember you have international viewers!! Twice now i have tried to find the "Discovery Go" and "Science Go" apps, as you have recommended, but they are clearly not available in Europe. Just a wee disclaimer for non American regions (or a confirmation when it IS available over here!) would be grand :^)
well they want to send chipsize object to proxima estimation are 20 years development + 30 years to get there that's 10 grams or so were talking about, if it takes 50 years to send 10 grams another 50 to double it you can start to calculate how long it will take to send humans. 10-20-40-80-160-320-640-1280-2560-5120-10240-20480-40960-81920 which would be the endstation... so approx 700 years
I agree. unless we go extinct as a species for any reason we will eventually have to set foot on other worlds. its simply as you said inevitable and we ought to be able to progress enough technology to be able to do it.
Isn't it crazy that all conditions on Earth are the best possible ones for life?!! Habitable planets can't be too different from Earth!!! How crazy is that! In a world where no two people are alike!
to be completely honest, I think we'll be long gone from this galaxy in 300000 years...i mean we will most likely have the technology to start messing around on the moon and Mars within the next 100 to 200 years, hell quite possibly in our lifetime technology evolves so much faster then people realize
the biggest problem we face in my opinion is distance, the galaxy is simply to large, we don't, and unfortunately, won't ever have the kind of powerful technology to traverse such distances.
Have they not thought of launching bacteria from earth to mars, specifically bacteria that can absorb certain chemicals on surface of mars and then produce oxygen and other substances as a byproduct?
Yes! Please do a series on overpopulation. It's a sensitive topic, but also very important for people to understand. I'm also super curious about some of the random related trivia that you're likely to dig up while putting it together. :D
I think we need to unite as a planet and stop fighting each other, we can all achieve so much if we shared and thought about the greater good. Greed, unfortunately holds us back.
I agree. I think that we really need to grow up. We are a young species so there is still left to discover. We can't be intelligent if we keep fighting each other.

sogghartha
"we lack the willpower to survive." bit premature to draw that conclusion, don't you think?
+sogghartha well if we can turn sea water into drinking water at a very low cost, then we can easily increase the size if cities near coastlines.
I Heard On A National Geographic Video That The Entire Human Population (7 Billion)Can Fit Into California..
it would be great if Dnews could do a series on over population. It's something that people need to be made aware of.
Yes please,
I'm very interested in that!
The sooner we leave the better.

IraqWarVet03 that's exactly the human geography course I take
but as countries go into the 4 th stage their pop will stop growing because education, birth control, etc etc
Couldn't most work towards living on an uninhabitable planet be also applied to living on a changed Earth?
It's pointless because the goals are for humans to inhabit another planet before the "deadline" which is Earth inevitable destruction. So moving into another planet with possibly a longer lifespan than our dear Earth is the logical investment to make.

Something that's always made me think, if we leave what will happen to all of the animals that are present on earth?
I had a question. if you put a turbine in space, and started to spin it wouldn't it spin infinitely since there is nothing to stop it in space therefore giving up infinitive energy? if so, why don't we do this already?
A turbine uses friction to produce energy, so the energy would run out pretty quickly. Any energy you put into it would be needed to keep it going
can't tell if troll or stupid

So if we do eventually move to a new solar system wouldn't we need to create a new calendar? Because I'm pretty sure that would create A LOT of problems.
each planet will have it own days nights summers and winters so yes but we can have the date based on pulsars stars cycles or a universal date system
Maybe we'll make a calendar like star dates from startrek.

How will we measure time on different planets
The same as we do here, relative to the time it takes to circle it sun, and the time it takes to rotate on its own orbit
Kinda a problem for interplanetary communication, especially computers.
+Mats Mokkenstorm if we become an interplanetary planet, there's a few ways it could go. either we all go by earth time, or we separately go by our living planets time and then we have a different time for space, maybe space time goes by earth time as a sort of commendation to our original planet
You should check out our Calendars series! :D
Stardates...Like in Star Trek
This channel is really freaking good, and this guy is too
Directly into the sun so we can't destroy another planet
You dont know how much energy is required to deaccelerate enough? do you?
Does it really matter the sun will destroy us and any planet regardless. You either burn via the sun or freeze via space either way we are fucked.
gcirc Your metabolism generates too much heat to dissipate in space, You would die from heat in a spacesuit if it does not have a cooling system.
There's no such thing as deacceleration. its positive or negative acceleration
Your weird do you really think when the sun expands your going to survive. Do you think you would survive if the earth orbit sifted to the kuiper belt or close to it. And yes I don't fully grasp thermodynamics please update me always willing to learn
The joke at 6:40 made my day. The simplicity just fit perfectly.

I think the show star trek had some of these values that we need to be taught so very badly
+Hetansh Parikh Well hopefully we will developed the technology in 7 billion years and 7 billion years is a very very long time
Not that I have any special knowledge on the subject, but I am certain humanity will not exist in 7 billion years. We will most likely cease to exist as a species in just I million years or far, far less. If, we are to develop the technology for interstellar travel, it will likely be in the next I to 2 hundred years. But, that is predicated upon the fact that we don't destroy ourselves and the Earth, which is the more likely outcome.
We need a world wide law saying that people can only have 1 child, that should cool down the population for a while.

Traces wrong about the Goldilocks zone requiring that a planet has liquid water as opposed to frozen water.
If we have a plentiful energy source, we can go to any planet that has frozen water. We can heat up the water and turn it into liquid water for our purposes. I'm not saying that this would be comfortable, but a habitable planet that is uncomfortable is better than no habitable planet at all
But a planet to hot is the real problem
Not necessarily. Dig a cave deep enough, and the rock above you will block the sun's heat.
go ahead and build a cave on Venus good luck with that. :P
I'm not advocating that caves be built on every planet that would otherwise be uninhabitable. Venus's atmosphere must be blown away with many nuclear blasts before Venus can be considered a candidate for habitation. All I am trying to do is expand the number of candidates available for human habitation. An uncomfortable but habitable planet is better than no planet at all.
Heat is worse underground you know...
If we cannot take good care of this planet, and refuse to get along with each other, why would anyone think things would be different any place else?
did he say frank ocean? wow. love it.

I read something recently in regards to an expected 'Population Implosion' as a result of an aging population, which in turn is a result of the same excessive breeding that has caused this popular belief that we're headed for a situation with an overpopulation. A Population Implosion would most likely lead to the opposite, underpopulation and difficulties maintaining a population capable of both breeding and maintaining societal needs. It would be very interesting if you did a series on both of these potential scenario and comparing them.
Love the sci/tech stuff... Keep it up!
With the rapid development in the fields of biology, it sounds like it'd be easier to genetically engineer humans to suit a potential new planet than it would to try and adapt it to suit us.
I hope you guys mention O'Neil Cylinders!
1:42 ONLY a couple of BILLION years before the Sun goes out, we'll never make it in time
@10:00 The plants don't create energy, they convert the sun's energy, but I know what you mean.
Loved this episode!
Awesome series, thanks guys! I think a series on overpopulation and ways in which we can deal with the coming 'major' issues our civilization will face in the next few decades is a great idea!!
dude please do a video on over population that is a great idea. your videos are so interesting
Yes! A series on over population would be so fun.
We could also alter our DNA to allow us to survive on different planets. Terraforming and changing an atmosphere will take too long, so why not change ourselves instead.
Fascinating subject, thank you !
Love your videos!
When i heard that this is going to be a 3 day series i was like...MAKE IT A 5 DAY SERIES!!!!!!
2:30 FYI, we reached "Peak Child" about a decade ago.
Population will peak in a about a century on 9 billion, (as babies just born reach 100-year old life expectancy)
After that population will go down. Watch "Don't Panic" by prof. Hans Rosling (RIP) for a better explanation.
The Size of the Planets will also influence how species will develop. I mean definitely gravity will have to weigh in.
i know DNews+ is busy enough on youtube, but have you been uploading on to itunes because i can't see any new episodes since your one about monsters. If not, why? DNews+ is a great thing to listen to during commutes and I miss being able to. But that being said, great show!
He said, (on the counter 15:59) Mars is not big enough to have atmosphere, but why does Titan, in spite of being smaller than Mars, have an atmosphere more dense than Earth's?? Yes, Mars does not have a magnetic field to sustain one, but Titan just debunked his statement of being too small.
i personally am so in love with our beautiful precious planet and all the amazing creatures and plants and life that i would never leave her....not unless it was my sole mission to create a sort of space "ARK" so that not just humans could leave earth, but all manner of flora and fauna was being collected and saved as well....all life deserves a chance, even if its not directly "useful" to humans, and we are responsible for all life on this planet at this point. it would be fascinating to see how over thousands of years not just humans evolve in space, but many many other life forms as well!
I believe in the “dirty garbage theory of life on earth”.
In the ancient past, a spaceship stopped on earth.
Opened the door and looked out. They said, “Nope, nothing here.”
Dropped there trash and flew off............
NOW, here we are!
One possibility totally overlooked in your video is building sustainable space colonies. Instead of looking for a perfect place to live, why not build one? Certainly difficult, but nothing fundamentally impossible about it. Plus a space colony can be moved over time to avoid long term hazards, unlike a planet. In addition humans should strive to live outside of gravity well instead of being trapped in one, as it provides vastly greater mobility.
I wouldn't never leave first I would leave in a different trip when I know everyone in the first trip got there safely
We will look back at earth from hundreds, thousands, millions, billions light years away to see our earth history and our memory of earth.
if we wanted to see earths past like that, we would have to travel faster than the information, which means going faster than light (impossible)
How can no one argue life didn't start in water?
If we didn't have those essential things, how could it have started in water?
Great show as aver Trace, but can i say, please remember you have international viewers!!
Twice now i have tried to find the "Discovery Go" and "Science Go" apps, as you have recommended, but they are clearly not available in Europe. Just a wee disclaimer for non American regions (or a confirmation when it IS available over here!) would be grand :^)
well they want to send chipsize object to proxima estimation are 20 years development + 30 years to get there that's 10 grams or so were talking about, if it takes 50 years to send 10 grams another 50 to double it you can start to calculate how long it will take to send humans. 10-20-40-80-160-320-640-1280-2560-5120-10240-20480-40960-81920 which would be the endstation... so approx 700 years
heyy, try to put the podcast un Spotify, is rly good.
You should do a series on ecosystems and overpopulation.
I'd like to see a series on oil and when we'll run out.
Trace supports the use of Dihydrogen Monoxide.
well that's the ultimate bug out, hope you packed well
yeaaaah ! i would absolutely go :D
awesome show by the way
Yes do an episode on future populations and water-wars
I agree. unless we go extinct as a species for any reason we will eventually have to set foot on other worlds. its simply as you said inevitable and we ought to be able to progress enough technology to be able to do it.
Isn't it crazy that all conditions on Earth are the best possible ones for life?!! Habitable planets can't be too different from Earth!!! How crazy is that! In a world where no two people are alike!
May I ask how could something on the surface of Mars overcome Mars's gravity and come to earth?
a meteor smashes into mars, and the force impact causes chunks to fly out at high speeds
Cool series.
Great vid! thanks!
to be completely honest, I think we'll be long gone from this galaxy in 300000 years...i mean we will most likely have the technology to start messing around on the moon and Mars within the next 100 to 200 years, hell quite possibly in our lifetime
technology evolves so much faster then people realize
the biggest problem we face in my opinion is distance, the galaxy is simply to large, we don't, and unfortunately, won't ever have the kind of powerful technology to traverse such distances.
I wonder is it even possible to fly straight at the high speen and not have a collisions.
Have they not thought of launching bacteria from earth to mars, specifically bacteria that can absorb certain chemicals on surface of mars and then produce oxygen and other substances as a byproduct?
These are very exciting times for human kind.
i would go only if there was a wifi connection, i hate it when my signal is poor . its worst than the dial up days.
Yes! Please do a series on overpopulation. It's a sensitive topic, but also very important for people to understand. I'm also super curious about some of the random related trivia that you're likely to dig up while putting it together. :D
