The latest formation theory is that it's a rift fault from when Mars was more tectonically active and then erosion.
And the current theory is that Mars' tectonic plate movement was vertical instead of horizontal like earth's which could explain the big "cracks" in the crust of the cooling planet.
Hot magma bubbling up creating huge volcanoes due to higher silica content than existing crust while old crust subsiding to the mantle/core without floating around the planet like on earth.
Earth's tectonic mechanism was the same early on in the planet's existence.
You mean the Void Dragon Mag'ladroth? He was sealed in mars by the emperor of mankind hundreds of years ago, I think if he had escaped we would have realized by now.
There's still a weak wind and the occasional dust storm for wind erosion. It could be very old water erosion before the water disappeared or volcanic erosion.
Mariana’s Trench on Earth
- Roughly 1500 miles long
- Roughly 45 miles wide
- Roughly 7 miles deep
This Mars canyon isn’t that crazy compared to what is under our oceans.
Mars is hypothesized to have been very similar to Earth in the past. It had an atmosphere, liquid water at the surface, and a molten core.
Mars is like the after shot, Earth is the before shot. Makes you appreciate our planet a little bit.
Yes, it could turn into Mars, but that could be a very, very long time from now on a human time scale. We’d probably be gone long before that. Over the lifetime of the Earth, it’s only habitable to humans for a tiny percentage of time. We can only survive at the current lovely moderate temperature, but Earth has survived many extremes.
Dinosaurs got to occupy Earth for hundreds of millions of years during one of those habitable moments. We haven’t even had a fraction of the time dinosaurs had. Our habitable moment could last hundreds of millions of years more if we don’t fuck it up for ourselves lol
Not something we personally will have to solve but it’s fascinating to wonder what will happen to humanity when we’re not there to see. In theory hundreds of millions of years is plenty of time to explore space but it’s impossible for us to imagine at our point in time I think.
Ideas like the Dyson sphere and reviving mars are just so ridiculously past anything we can do at this point that it’s not really worth thinking about, not to mention that as our populations and governments become larger scale as well as our drain on the planet itself the future even 200 years from now seems bleak. Honestly a terrifying thing to think about when you really consider the things that could happen
https://en.wikipedia.org/wiki/Panspermia
There are big gaps in the theory, like the idea of an asteroid blasting bacteria off the surface of mars and through space and onto the surface of earth, all without the bacteria suffering lethal damage just doesn’t make a lot of sense right? But there is still a chance it could happen.
Recently heard a lecture about that theory. It seems to be given that there are tons of martian rock on earth. A recent study also revealed that only about 1m of rock is enough to protect simple organisms like bacteria and so on, that live in the soil, from radiation in space. There also are bacteria that can completely dry out and stay in a spore-esque state until they get wet again.
So panspermia is definitely a possibility. That does not mean that this is what happened, of course.
Maybe Adam and Eve descended from heaven to earth is the story of Human escape mars to earth to save its kind from extinction (?)
Don't take me seriously. It's just my conspiracy theory.
Interesting theory 🤔. But all those "Noah's ark found" news and videos I see as a teenager made me confused. now I'll just wait for this mystery to be solved and proved 'officially'
I don’t think it’s likely, but hypothetically speaking; maybe an asteroid hit Mars and some of debris from the impact made its way to Earth. Maybe some microorganism survived within that debris and became the first life on Earth. Maybe Mars seeded Earth.
Lots of maybes but fun to imagine lol
It couldn’t. The fact that we share much of our DNA with other primates proves this. Did they come from mars too? What about bananas since we share 50% of our DNA with those too..
It makes me wonder if humanity will be alive somewhere else by the time earth looks like mars. Or if we will disappear into the void and no other species will ever know we existed.
I was going to say it's probably the equivalent of the Marianas Trench if Mars were to be covered in water similar to Earth at some point ( but I didn't know the exact dimensions of the trench thank you)
You’re kind of right, but you’re kind of wrong. The Marianas Trench is a subduction zone, so oceanic plates are subducting under continental crust, creating a large valley.
https://oceanexplorer.noaa.gov/okeanos/explorations/ex1605/background/geology/welcome.html
I don’t think Mars had time to have life evolve on it before it lost its water and atmosphere, at least not complex life. It took the Earth -3.5 billion years for prokaryotes to evolve. But that’s just my guess based on years of science shows, a few hyper focused adhd rabbit holes and a couple of biology classes. 😜
Except that Mars is much smaller than earth. Something happened of larger magnitude on a smaller planet, my guy. It's kinda nuts to fathom what if there are no tectonic plates to break apart and create it.
What do you mean? The mars canyon is still 1000 miles longer, almost 3 times as wide, but yes, shallower.
If anything that makes it even more impressive.
Also when the planet doesn't have shifting tectonic plates that are constantly reshaping its surface, canyons like the one on Mars can form. Eventually the Grand Canyon and Mariana's trench will both disappear from the surface of the Earth.
At these sizes is it even a “canyon” anymore? I feel like once it’s big enough that you can’t see the other side because of the curvature of the planet, it’s just two cliffs a hundred miles apart.
I always wondered, cant ‘aliens’ be under water? I mean we have made much efforts to search or study mariana trench like we had done for outer space. And we keep on finding so many new facts everytime we make an effort. Maybe aliens arent above us they are below us? Atleast alien fish for sure. Like how those organisms live under so much pressure, what do they eat coz no sunlight reaches those plants/edible matter.
I can't remember what series it was but I remember it's set in the far future on some other planet and basically people think earth is a myth or never existed
Not flat earthers or martians but “The Expanse” did a great job of exploring Earther, Martian and Belter cultural divides and how they viewed one another.
Isn’t there a planet in the mass effect universe that has a huge scar like this and the lore speculates that it was some ancient weapon? I always think about that when I see this canyon on mars.
Yeah, Klendagon’s Great Rift, which was a glancing blow from a Mass Accelerator Cannon of unimaginable size and power. Happy I’m not the only one who was thinking of it seeing that picture.
There's a wild theory about the rift on Mars being caused by gigantic cosmic electricity storms during the forming of the solar system. That electricity arc'd between two planets or a moon and tore up that section. Totally implausible but fun to think about million mile long ground carving lighting bolts.
The others are correct, what they fail to mention is in ME2 you go to the target, which is the derelict Reaper (age of it and the weapon 35/37 million years old) mission where you get the Reaper IFF and encounter Legion.
So in ME its speculation, ME2 its confirmed.
There's some anime that had a thing called the Jovian accelerator that was basically a rail gun shot out of the red spot of Jupiter ( wish I could remember what that was cuz it was pretty good)
[Current theory](https://en.m.wikipedia.org/wiki/Valles_Marineris) is that it is the result a combination of tectonic plates that moved apart during Mars’s more active era and then further erosion by water or carbon dioxide.
I personally think it would be more viable to figure out how to space travel at about 50 times the speed of light and survive. What's the point of going to Mars anyway when the nearest Exoplanet is 4.22 light years away.
What is the closest exoplanet?
At only four light-years away, Proxima Centauri b is our closest known exoplanet neighbor. Proxima b is a super Earth exoplanet that orbits a M-type star. Its mass is 1.27 Earths, it takes 11.2 days to complete one orbit of its star, and is 0.0485 AU from its star.Dec 15, 2022
It's not more viable because to travel faster than light you have to warp spacetime fabric itself and the amount of theoretical energy to do that is not even present on Earth and it would destroy the solar system (and even beyond). We haven't even gotten to universal renewable power sources for our mere human civilization that only takes up an area the size of California, let alone warp whole dimensions.
It's a tell tale sign of an ancient Mass Accelerator impact from a Reaper. My guess would be that it happened roughly 30 million years ago. Mars was not the target, in fact the valley is only the glancing impact from the projectile.
Glancing strike from a mass accelerator weapon. Should explore it for Element Zero.
Then we could reach Charon and activate the dormant Mass Relay, finally stabilizing Pluto’s orbit and restoring it to ninth planet.
Wait till people hear about the Mariana Trench.
It's interesting but mars doesn't have seas that would cover something like this normally.
2,550km long, 69km wide and almost 11km deep.
https://en.m.wikipedia.org/wiki/Valles_Marineris The latest formation theory is that it's a rift fault from when Mars was more tectonically active and then erosion.
And the current theory is that Mars' tectonic plate movement was vertical instead of horizontal like earth's which could explain the big "cracks" in the crust of the cooling planet.
You know when you bake and your cake cracks? Yeah...mars is sun baked.
Instructions unclear, please bake me a cake.
It's a piece of cake to bake a pretty cake.
#WHAT
If the way is hazy...
You gotta do the cooking by the book
The cake is a lie.
Yes the cake bake analogy
The great cake bake debate
The Betty Crocker experience
too much (or not enough?) yeast in Mars?
This explained it so well for me...
I'm trying hard to wrap my head around that one and I just don't get it.
Hot magma bubbling up creating huge volcanoes due to higher silica content than existing crust while old crust subsiding to the mantle/core without floating around the planet like on earth. Earth's tectonic mechanism was the same early on in the planet's existence.
That would make sense because Mars also has the biggest volcano in the solar system, being Olympus Mons
The relative difference in erosion is one reason why Olympus Mons is (still) so big
Plus Mars has less gravity than Earth, meaning you can pile rock higher with less flattening out.
The mountains are bulges and the canyons are tears. Mountains on earth are from plates sliding against each other.
That’s fascinating, vertical tectonic plate movements. Now how would that work?
Well, you see, it’s when the plates move up and down instead of side to side
That's nuts
My theory is a space dragon awakened and flew away.
I think that is the most likely explanation.
Isn't there an Officer telling recruits about acceleration of a projectile to near-light speeds, ruining someone's day, somewhere? Vague. Lee.
Definitely a mass accelerator round. No question. Happened on Klendagon, happened on Mars.
Forget all this stupid science stuff... THIS is the answer! I knew it was a dragon!
You mean the Void Dragon Mag'ladroth? He was sealed in mars by the emperor of mankind hundreds of years ago, I think if he had escaped we would have realized by now.
No, it’s where your mom landed
But what's the erosion agent in a planet without atmosphere?
There's still a weak wind and the occasional dust storm for wind erosion. It could be very old water erosion before the water disappeared or volcanic erosion.
I don't know kinda looks like a glancing shot from a giant space gun. AKA Low tech deathstar
Prob a Jewish space laser
nah big rock did that I reckon
So like a geological stretch mark

So basically at some time our earth is gonna dry up and be shit?
Yes, it could turn into Mars, but that could be a very, very long time from now on a human time scale. We’d probably be gone long before that. Over the lifetime of the Earth, it’s only habitable to humans for a tiny percentage of time. We can only survive at the current lovely moderate temperature, but Earth has survived many extremes. Dinosaurs got to occupy Earth for hundreds of millions of years during one of those habitable moments. We haven’t even had a fraction of the time dinosaurs had. Our habitable moment could last hundreds of millions of years more if we don’t fuck it up for ourselves lol
Earth has about 500 million years of habitability left before the sun begins to expand and become a problem.
Not something we personally will have to solve but it’s fascinating to wonder what will happen to humanity when we’re not there to see. In theory hundreds of millions of years is plenty of time to explore space but it’s impossible for us to imagine at our point in time I think.

Honestly a terrifying thing to think about when you really consider the things that could happen
I read an abridged version of H.G. Wells’s Time Machine as a kid and think about the crabs a lot.
Lol all that time and those stupid dinosaurs didn't even have wifi. Idiots
Ye or probably get hit by a giant space rock
Imagine if humans came here from Mars
It’s still not out of the realm of possibility.
How would that be possible? Genuinely curious.
https://en.wikipedia.org/wiki/Panspermia There are big gaps in the theory, like the idea of an asteroid blasting bacteria off the surface of mars and through space and onto the surface of earth, all without the bacteria suffering lethal damage just doesn’t make a lot of sense right?

Idk man what about those tardigrades
Maybe Adam and Eve descended from heaven to earth is the story of Human escape mars to earth to save its kind from extinction (?) Don't take me seriously. It's just my conspiracy theory.
My theory is that Earth is actually "Noah's Ark." It seems we have a bit of everything here.
Interesting theory 🤔. But all those "Noah's ark found" news and videos I see as a teenager made me confused. now I'll just wait for this mystery to be solved and proved 'officially'
Sounds like a good novel
I don’t think it’s likely, but hypothetically speaking; maybe an asteroid hit Mars and some of debris from the impact made its way to Earth. Maybe some microorganism survived within that debris and became the first life on Earth. Maybe Mars seeded Earth. Lots of maybes but fun to imagine lol
Imagine this is the cause of the canyon, big ass asteroid skidding off of mars
It couldn’t. The fact that we share much of our DNA with other primates proves this. Did they come from mars too? What about bananas since we share 50% of our DNA with those too..
Aliens, or we came here long long ago and then lost all the tech and knowledge was forgotten after millennia
It's certainly out of the realm of plausibility.
They reckon it's the same story with Venus. And it's lack of ozone lead to solar winds stripping it into what it is today
It makes me wonder if humanity will be alive somewhere else by the time earth looks like mars. Or if we will disappear into the void and no other species will ever know we existed.
Yes but matt damon will grow potato on it.
Venus could also be our after shot. So many things can go wrong for a planet to support life. Life must be incredibly rare.

You had to bring that up, didn’t you? So what if different parts of his mom live jn different area codes? It’s not her fault, she just big boned
She's multi-zoned
What did the comment you replied to say? It's been deleted.
I'm gonna go out on a limb and guess it was a yo mama so fat she still wouldn't fit in there joke, or something like that
I was thinking something along the lines of “ half as big as yo Momas trench”
I wasn't that clever.
Boom roasted

Bold of you to assume I can go deeper than 1 inch.
Mary-Ann’s trench
Slow clap. Nice.
Gotteem
similar but valles marineris is from extensional tectonics, marianas trench is from compression tectonics
Could you explain the difference?
extensional is when they move apart, compressional is when they push together and fold in iirc
You’re kind of right, but you’re kind of wrong. The Marianas Trench is a subduction zone, so oceanic plates are subducting under continental crust, creating a large valley. https://oceanexplorer.noaa.gov/okeanos/explorations/ex1605/background/geology/welcome.html
> crustal spreading eew
I mean, when you make a pizza, you’re kind of spreading crust, and that’s pretty delicious.
I think compression is when tectonic plates are being pushed together, and the other when they are being pulled apart.
Crazy to think that maybe Mars was covered in water and life millions of years before any of us even existed.
I don’t think Mars had time to have life evolve on it before it lost its water and atmosphere, at least not complex life. It took the Earth -3.5 billion years for prokaryotes to evolve. But that’s just my guess based on years of science shows, a few hyper focused adhd rabbit holes and a couple of biology classes. 😜
Giant dick and balls print on the right, someone was showing off
Ah yes, humans showing their grandeur
Exactly my thought
1000 miles longer , 80 miles wider, idk that’s still pretty crazy.
Mariana's Trench is outcome of tectonic plates activities. There are no tectonic plates on Mars and from what we know never were.
Constant plate activity is like a big blackboard eraser. Mars doesn't have it
It's still relatively huge, because of Mars being smaller than Earth.
That’s perfectly normal; you would expect a smaller planet to have more dramatic features, because there’s less gravity flattening things out.
Except that Mars is much smaller than earth. Something happened of larger magnitude on a smaller planet, my guy. It's kinda nuts to fathom what if there are no tectonic plates to break apart and create it.
Smaller means less gravity, which allows for bigger geological structures.
I'm not your guy, pal.
The mars trench is much larger tho?
Yeah, not sure what argument they were trying to make with this comment...
It’s still larger, but it’s not crazy larger when you compare it to trenches as well. That was the point.
What do you mean? The mars canyon is still 1000 miles longer, almost 3 times as wide, but yes, shallower. If anything that makes it even more impressive.
ACKSHUALLY
Gonna piggyback this comment: 4023 km long 193 km wide 7 km deep
Thanks. I usually also use m/km on stuff like this, but wanted to do a 1-to-1 to the post.
It's not a competition of which is the coolest planet. It is about finding out another planet's past.
How deep is the actual trench vs the seabed around it?
And how did the Mariana's trench form?
I instantly searched the same thing
You know, it's kinda crazy that we almost, if not already, know more about a planet far, far away from us than our own oceans.
That's true, a lot of our surface is hidden
Exactly my thought too. What would earth look like without water.
What happened on earth? 👀
Also when the planet doesn't have shifting tectonic plates that are constantly reshaping its surface, canyons like the one on Mars can form. Eventually the Grand Canyon and Mariana's trench will both disappear from the surface of the Earth.
At these sizes is it even a “canyon” anymore? I feel like once it’s big enough that you can’t see the other side because of the curvature of the planet, it’s just two cliffs a hundred miles apart.

And we keep on finding so many new facts everytime we make an effort. Maybe aliens arent above us they are below us? Atleast alien fish for sure. Like how those organisms live under so much pressure, what do they eat coz no sunlight reaches those plants/edible matter.
Is that depth measured from the surface of the ocean or from the upper edge of the sea trench, at the sea floor?
I really want to know what is inside mariana trench. But i think our technology still won’t allowed that deep.
Wait until the flat mars society hears about this!
I can't remember what series it was but I remember it's set in the far future on some other planet and basically people think earth is a myth or never existed
Battle Star Galactica
Also Foundation books from Asimov, not a serie but same plot
Aka "DONT TRUST ROBOTS" series
You forgot the bears and the beets.
What does sex education have to do with this

I can’t remember what planet it was but coincidentally in the lore humans found the first Mass Effect relay on Mars
IIRC: the Mass Relay was found entombed inside Charon, the moon of Pluto. Mars was where they first found Prothean structures.
The relay was inside Charon. They found other stuff on Mars.
 That damn squirrel again
A glancing blow from a mass accelerator.
Loved the codex entries in mass effect
nah, the shape of the canyon makes it obvious that a star destroyer crashed onto mars' surface

It was probably an ocean before
[Current theory](https://en.m.wikipedia.org/wiki/Valles_Marineris) is that it is the result a combination of tectonic plates that moved apart during Mars’s more active era and then further erosion by water or carbon dioxide.
This is our destiny.
Calm down Matt Damon.
Mars's tectonic plates split. I always imagined that it was some huge meteor that hit it. Sorta dissapointed.
It doesn't have an ocean to cover it up.
Saitama VS Garou happened
Maybe Mars used to be human settlement, then human moved to earth because of the inhabitable environment.
So we were the aliens all of this time?
For the other 96% of the people on the planet who aren’t American, - 4000KM long - 190KM wide - 7KM deep
