What if Mars Were Habitable? 

You forgot that if Mars had an iron core it would also have plate tectonics of some kind and the 3 major volcanos would be active, most likely in cycles. Also Humanity wouldn't have the greatest question of all time: "Are we alone?"

Personally I’d love to imagine a scenario where people were originally right about Venus: a warm paradise world veiled in mist, with lush forests and shallow seas.

One thing I would imagine is that the Martian landscape would actually be very different - you can very clearly see the asteroid impacts, which would be far less visible or not present at all if Mars had an atmosphere that could support life.

Sir David Attenborough, the leading member of the International Martian Exploration Society. I can imagine him in a hazmat suit (as to not disturb the martian environment) researching all the new species and broadcasting it all on the BBC. Now that's a documentary I would love to watch!

Please do a video on what if Venus was Habitable? Also What if the East African Federation became a real sovereign superstate today?

Do one were Venus was habitable

so a golden age of exploration for humanity. I love it!!

So, just a smaller earth, mostly looking like Greenland and Australia.

The book: "A World of Difference" is set in an alternate reality. A nice read. The major change is: "Mars is too damn small; but what if it weren't?"

Coal is from the Carboniferous because it related to a very specific type of large scaled tree that has since gone extinct. Oil has nothing to do with the Carboniferous. Most oil comes from small photosynthesizers like plankton and algae. The vast majority of oil formation was after the Paleozoic Era (which the Carboniferous was during the later end of)

It would have been nice to see an ocean on Mars....

A World Of Difference by Harry Turtledove has this as its central theme, and they call it Minerva instead of Mars

its entirely possible that martian life would not be reliant on chlorophyll, so martian life could have used, say, retinase or bacteriochlorophyll and obtained a purple color. (i am not a biochemist and i learned of these chemicals from a few minutes of google search; take what i say with a large pinch of salt.) both mars and earth have a significant amount of silicon; silicon-based life is also a possibility.

You underestimate the butterfly effect, my friend. The changes would be much more drastic. Hard to say what exactly would change, but culture would be very space-centric. Therefore, we might even go ahead with terraforming Venus and sending the co2 to Mars to fill up the atmosphere a little more so more land would be habitable for life (greenhouse effect and thicker atmosphere, right?) gr8 vid man :D Venus next?

What an awesome video, this obviously took a lot of research. Great job

Love your videos! Keep em up

I can tell that this video will be amazing 😊✨

Yess do a venus one too

This was a fantastic video!! Thank you so much for this! Did you take any inspiration from any existing fictional stories or just sort of take your own swing at it? Thanks again! God be with you out there everybody! ✝️ :)

For Mars to be habitable, it needs a large moon for a satellite that would help the planet to generate a strong magnetic field. That would allow Mars to retain its atmosphere.

Man I’m really loving the space videos is quite different compare to the normal alternate history

Can you do what if Venus was habitable

Seems like Venus, had it not theoretically had a collision reversing and slowing its rotation, could have even more likely been habitable by life....seems like another video.

“Yet across the gulf of space, minds immeasurably superior to ours, regarded this earth with envious eyes, and slowly and surely drew their plans against us.”

Now please do, what if Venus was habitable?

I hope they make a movie about this.

Europeans be like: Yoink, Mars is now mine.

Fed video Neatling

Idk why but I keep on watching this video

Shoutout to all who still remember the game "Ultima: Martian Dreams." ^^

If we magically warm up Mars there would probably be a war of he is going to own it, basically just like another race for the moon, but instead for Mars.

Fun fact: Mars will be habitable in the past and future.

Another major prerequisite is rapidly growing populations. That started slowing down during the mid 20th century. Tbh with the way things are going I don't see space colonization being economically beneficial until we get to similar growth rates we had between 1870 to 1970. Maybe even higher.

Can you PLEASE do a video like this, but Venus is habitable?

Letsss goo!!!

People forget how much of our technology revolves around space travel, this alternate world would be so much more technologically advanced

You should do a video on colonizing Venus

This would be interesting and it doesn't have many downsides either

Please make a video about if venus was habitable like mars in this video

Poderia fazer o vídeo da Cornélia do norte e seus aliados?

For no particular reason, here is the start of my WH40k story where they terraform "Completely not Mars" by placing a ring around it to reflect sunlight to the surface. Chapter 1, Introduction and starting the glass mandala. "So, you've chosen your punishment?" the Arbiter asks. The accused looks around for a moment, scratches the stubble on their chin, seems to for a moment talk to themselves and then speaks up. "Yes, your honor". The Arbiter bangs the gavel and the guards take the accused away. After a distance of travel, both through the channels and conduits of the justice system, and through the paths of the warp. The accused, a few servitors, a simple manufacturing ship and the guards assigned to guard others from him, and the guards assigned to protect him from others, settle in orbit of an arid world, only underground water deposits and polar icecaps, no atmosphere. "So we're here." the mechanicus states with a simple tone. "Fine, lets get started." The first step is obvious, finding the right silica rock in system and putting it in high orbit, using the machinery brought, to dissassemble the rock into the tiniest shards of glass and with the smallest of efforts drop them into their orbits. After some moments there would be a beautiful ring mandala praising The Emperor, of multicolored glass, reflecting light onto the surface, and as is said to be the first step, there will be light. The accused sits and reads for a moment, glancing every now and then at the indicators, all is going as was meant. At the corner of his eye, he sees one of the guards take off his helmet. --- Chapter 2; What the hell are we doing here. "What the hell are we doing here." the Guardsman says. He looks around at the assorted crew of guardsmen, space marines, servitors, staffers and a few mechanics. The accused looks up from the paper, throws it on the table and perks upright. "So, they gave me a choice, turn into a servitor, be sent on a crusade into the eye of terror, or get one ship and one empty planet and a rogue trader charter on anything produced on that planet." The Guardsman motions to the ragtag band of marines in different armors. "Yeah, they were given a choice of which crusade to go and they chose pacifying this sector and making sure I dont step out of line." The accused snorts and continues. "And you're here to make sure they dont step out of line. Funny huh, cant say I envy you." The Guardsman looks at the marines, then at the accused, then back, and again. His lips make a tiny bit of quiver then he stands up and says "Sir." Moments later the machine beeps and displays a picture of a disk of glass shards on a mandala around the planet. --- Chapter 3: A couple of days later in the mess hall. A couple of days later in the mess hall. The quite bustling and chatter of the mess hall echoes for some distance, quiet though it is, down the hallway. The accused sits in his room, the door open, and listens. What he hears are discussions ranging from the food being served, to debates on how much of a failure the accused is to be assigned a rotten job like this. He sits, and waits, mess just started so everyone is still Rambunctious and active, a bit later it will be calmer. He looks at the packets of food on the table, grey brown plaststeel packages. On top reads "Starch Intolerant Ration" with a small text below indicating that it is D quality military ratio. Next to it is a can of Corpse Starch. He looks at it intently, as if that single can represented all that is wrong in the imperium and his current predicament. He glances at the clock on the wall. Its been long enough now. Purposefully getting up and walking to the mess hall takes but a few moments. The bustle quiets down when the accused enters the room, everyone glances, some return quickly to their dining, some do not. Accused looks around and nods at diners and speaks. "I know you've been wandering what kind of hell went down to be sent here. Suffice it to say, I saw a lot of stuff wrong with the system, i complained more, was proven right in my complaints, and told that since i'm so good at pinpointing patterns and showing how things work. I should show everyone how to turn a wasteland to a garden world, that or the options i mentioned earlier. Vivisection was also mentioned." The collected crew let out a few huhs and ahas. "Okay, so I have 1 job, and one rule for today." The people look at him a bit annoyed, rules, already, they seem to think, but they are willing enough to hear him out. "First rules first." He picks ruffles through his bag and picks out a can of Corpse Starch. "This stuff, its not called corpse starch because its like starch for your body, its called that because its ground up human. Now i dont know about any of you, but i'd prefer we store all this stuff and wait for the day we need to host some blood ravens or flesh tearers." He picks out the ration pack from the bag and throws it on the nearest table. "Now one of the things I asked this ship to be filled with to the brim are meals, not made from humans, and seeds." A guardsmen looks at their meal and laughs, thinking it must be a joke of some kind, a large marine clad in blue places his hand gently on the shoulder of the guardsman and nods with a sad grim expression. The guardsman goes pale in the face. "So, lets start with that, no more eating humans, the other part is we need to send an expedition to all the planets in system to see whats around and if there is anyone or anything we should know about." The collected crew stands up and stars hauling towards the launch bay, as they walk down the hallway a faint sound of someone vomiting can be heard. The maintanance Mechanicum beeps, picks up a mop, and starts heading towards the sound.

You made the map?

He touched on the location of Mars. Mars is located at the very end of the habitable zone and with an atmosphere and it would still be very cold. I read that if Mars had an atmosphere they estimate the warmest temperature would be about 62 degrees in the summer.

what if mars had life at the same time earth had life and there were two self-aware species

Can you do Venus next?

How cool would it be if Mars AND Venus were both inhabited and we could travel between all of these planets

If the US in this scenario continued to invest in the Orion nuclear pulse jet spaceships they would have ships in their inventory that could travel to the red planet in only a few weeks. These large ships would also be crewed a hundreds of people.

If the Mars colony industrializes, they could increase the density of the atmosphere with waste gases, for example, iron refining produces oxygen

new human step: make mars warmer

It amuses me, we F-up a paradise planet and look at inhospitable rocks "out there" and play "what if".

thumbnail animals are from spec evo world Birrin i think

I always hope this was real 😢😢

a better world...

I couldn't imagine how catastrophic the cold war would be 😭😭💀

I live in the town in the picture in the thumbnail

Mars core needs a big injection of surfactant to get thay dynamo rollin'...

Algae and photosynthesizing bacteria in the ocean would perhaps form some fossil fuels. What of methane clathrates?

I wish this was true

Who would go there to live central aisan nomads or just the us

what if Venus was habitable?

Moon moment

what if we actually came from aliens? that would explain the cambrian explosion

Great scenario except the continents would look different from the mars in the real world because mars is like earth in this video the continents would move

next up: what if poland landed on the moon before the US (in this scenario poland wouldve had to become self-governing after ww2)

Do venus now!

Can you do what if Christianity never took power in Europe? Or What if the Norse never converted?

why would the ESA & NASA be contenders? both parties were already allied under NATO, which facilitates dialog.

Well, do you know how it would turn out? Both Mars and the moon would break away and declare independence, and we'd have a beautiful cold war in space

Idk maybe? All Hail FTs 🏴🏳🏴🏳

Actually lunar industry would be easier due to lower gravity

(Inserts 1950s commercial voice) Hey there kiddo are You tired of the everyday monotony of Earth? Do you have a adventurous heart? Then join NASA today! in the new Golden Age of Exploration of Tomorrow!

Honestly my theoretical timeline in this alternate space race is American moon base in the early 80s, Soviet manned moon landing and expansion of Americas moon base in the late 80s, US expansion and creation of unmanned lunar outposts pocketed over several strategic locations across the 90s (essentially reststops for future efforts and supply depots, and places to refuel rovers etc) alongside first manned landing of Mars. End of American international space operations in favor of a national focused one, resultantly no ISS instead a purely American Space Station. Temporary slowdown of US space program in the early and mid 2000s mostly focused on refurbishing existing assets, with the notable exception of the creation of a early reusable rocket system in the works and the complete temporary cut of Mars programs. Reusable rocket in full use into the late 2000s, also first European manned landing on the moon, causing a revitalization of the American space program alongside Chinas own growing efforts. Massive expansion of US Lunar operations in the 2010s including the start of moderate scale mining and manufacturing, return trips to Mars and establishment of Mars bases for future temporary inhabitation during missions there. European Moon base in the late 2010s probably around 2018 or 2019 as well as a Chinese manned lunar landing, US probably establishes 'exclusion' zones near its facilities to ensure their security and begins to militarize the moon due the military nature of Chinas space program, and its more importantly outright ARMED nature. China begins a rushed effort to establish its own moon base in the early 2020s and Europe probably plans out a Mars landing in the mid to late 2020s America probably establishes a more permanently inhabited Mars base in the late 2020s utilization a rotation system, reusable rockets, and the shipping of new reusable rockets from the moon. Coincided with this is the further expansion of US mining and manufacturing on the moon including the arrival of American corporate interests to the moon taking advantage of American infrastructure to establish their own efforts such as rare resource mining and manufacturing only possible in low gravity environments both being immensely automated with minimal human oversight. Russia, assuming the Ukraine War (if it even happens in this timeline) has ended will probably revisit the moon and establish their own moon base in the early 2030s with many small space programs such as the Japanese space program doing their own first moon landings in the early, mid, and late 2030s. Also probably the creation of Chinese and Europeans delayed space station efforts seeing fruit with their own space stations. Past this the advancement of the various programs is just entirely unpredictable especially with the hard to predict state of geopolitics and other factors in play. Though id predict that despite its headstart the USA would not have the first full on colony on Mars due to unwillingness to break space related treaties meant to prevent land grabs and will instead reorient away from Mars to the rest of the solar system till someone else makes a colony first. This would put them in a great position to have the most widespread and expansive space colonial 'empire' however due the build up of infrastructure and bases across the solar system once the colonial race starts up and will potentially claim entire small celestial bodies such as among Jupiter's moons.

real question: what if romania was habitable?

Eventually it will become the Expanse lol

Do "what if Jupiter wasn't habitable"

On this timeline Mars become another Africa with native but less advanced population and they are conquerend and scrambled by major powers leading in a colonial race for the planet.

Wonderful Video, so What if Saudi Arabia was colonised? What if Capitalism never existed?

🤔……………………………………………….😜🤪‼️

I'd sell my soul to the devil if I could live in that world.

It all depends on the mass and radius of the planet, afterall. Mass is not a prerequisite for the object to just have a spherical object, but for other factors as well. Both Mars's mass and radius - especially the mass factor - is so low that it couldn't support neither plate tectonics nor an Earth-like atmosphere. For such atmospheric chemistry and plate tectonics, a dense core is required, hence, a heavy-metal one, preferably consisted of ferromagnetic elements so the object can have a dynamo effect to produce the magnetic field needed. Also, radius is crucial. Mars should have a radius at least equal to Titan's so it would be heavier, having a much better possibility for heavier elements to compose its atmosphere and its core. Bigger mass combined with the longer distance from the Sun relative to Earth, would give a faster spin (probably equal to that of Earth's) and as a result plate tectonics would certainly take place.

We will pollute it with garbage.
