if you add "may/might" to a sentence its pretty much worthless info tbh
Not everybody uses kilometers
When SciShow and TH-cam decide they don't want comments outside their embraced politically driven ideological filter intruding into their Echo Chambers'...they BOTH discretely "Shadow Ban" and turn off "Notifications".
Buen video, si se le diera más materia continuemente a marte al aumentar su masa y tamaño, crearía fricción que irá al centro del planeta, para crear electricidad y tormentas de plasma con su atmósfera, creando reacción en cadena para liberar el oxígeno de el oxído de hierro, aumentando temperaturas y así hasta poner en marcha el núcleo otra vez, cuando tenga 0.55g de gravedad y sus montañas colapsar hacia abajo por gravedad, serían los últimos movimientos de la tierra en marte para hacerlo habitable, sigue crear una luna para tener baricentro que mueva la lava y transformar movimiento cinético con gravedad en energía del nuevo manto de marte, así sería una tierra en miniatura que será el primer planeta terraformado por la humanidad sugerencia.
It’s crazy to think about vast ancient oceans just disappearing like on Mars.
There are 6 million-year-old footprints made by a bipedal primate on Crete, as the hominid walked on the muddy shore of the Mediterranean, when the sea levels were dropping and the Mediterranean was dying. The entire sea entirely dried out, and basically turned into a vast desert, until the Atlantic broke through cliffs at the Straits of Gibraltar and flooded it again. So, it has happened here too, although different processes were at work on Mars.
I mean, that was just a *climate change*
You mean like earth in the future
The universe is an excellent magician
Better to lakes that mercyless tidal waves,too much man.prerfect poe
It will also be rewarding to look at much of Mars' topography with an eye as to how early Martian oceans intermittently turned to glaciers, melted... multiple times, until the water evaporated/blew away with the atmosphere.
There are many Martian features that emulate the Washington State scab lands, which were created by melting glaciers, releasing vast trapped lakes in massive floods.
maybe
I think those are evidence of liquid runoff.... not necessarily water.
Wouldn't it be something if a surprise mantle plume created a new volcano that was active for a while?
maybe
I sung happy birthday to myself last year. Im at least on the same page as the rover if not as scientifically advanced.
I'm not sure if if it's in exactly the same area, but I'm just imagining how potentially frustrating and yet fascinating that could be if the seismometer from InSight ended up getting wrecked by that
Like, I'm sure it could send back some really cool data before being destroyed! But also, man. That's a lot of money, effort, and resources
ummm... hawaii is an active mantle plume. its been active for like millions of years now. I thnk yellowstone in the US is also a mantle plume volcano that is active.
The heart of the Red Planet still beats even as its surface has frozen, dried and rusted.
maybe
Hail the Omnisiah
@@gregfisher4147 Huh. Never heard of that meme before, had to look it up.
I'm not used to subdued Hank anymore, lol. Lately I've been watching his channel and vlogbros where chaos reigns.
Chaos hank is the best hank lmao. Make sure to watch his tiktoks too xD
Pohl crater is named after the legendary US science fiction author (and agent, editor and former Communist party activist) Frederik Pohl(1919-2013), whose very long career lasted from 1937 to 2011. Among his Martian works is the novel Man Plus(1976) about a US astronaut-turned-cyborg on alternate timeline Mars (USA landed on the Moon in 1960, but Britain and Pakistan are part of the Soviet Bloc).
So the next questions I would have are, if it IS geologically active. Why doesn’t it have a magnetosphere? And what about the methane they keep detecting that people said could be caused by life? Is it possible it’s just a part of these geological processes instead? I’m looking forward to future developments here 😊
The problem is mars once had intelligent life like earth and vast oceans but like us the polluted the ocean with plastic until the density of plastic peaked and The Creature comes to suck up the ocean as a quick way to gain large amounts of plastic some say it evolved from a plastic eating bacteria that’s evolving on earth
Mars lost it's magnetosphere a long time ago, there is also speculation that Earth may have lost it's magnetosphere briefly.. there are massive changes going on in our solar system right now and it would be interesting to see if they do JumpStart Mars.
But since this little program has failed to mention all of the other factors it's hard for people who do not obsess over space science to understand what's really happening
Isn't a magnetosphere created by constant mechanical work from a spinning core? A lava lamp core wouldn't have the same actions? idk. we know little about mars, the confidence in which we talk about it based of single studies is wild to me.
you can have a hot core without having the dynamo craeted by a solid core rotating inside an outer liquid core. a hot core alone does not create a magnetic field you need rotation relative to some outer core to generate an EM field.
Jeez, Mars has been volcanically active more recently than I thought 😳
maybe
@@flipnshifty that's a lot of maybes, baby
Hank is comforting as always❤️❤️💯💯
Couldn't the quakes on Mars be "Frost Quakes". We get Frost Quakes in Canada when the temperature drops sharply and the ground Frost moves deeper.
The Quakes from Frost can set off Seismometers and feel like a real Quake.
So considering how cold Mars is, and knowing that Mars has weather that could cause changes in temperature and might cause the upper layers to freeze variably at different depths.
maybe
Sideshow is failing to mention that many other planets in the solar system are waking up, the suns effect on the planets, or that we have been dealing with denser space as a result of the galactic current sheet.
Omitting all of these details in a scientific presentation means one thing alone it is propaganda for scientists don't omit massive details propaganda does, why would they want to admit these details because then they would have to acknowledge the fact that Earth is dealing with all of these changes as well, and it's hard to tax us to death if the solar system and beyond is causing many the effects seen on Earth
Interesting point. Would a frost quake ever go above 4 quake?
Very interesting. Since we don't have multiple monitors, we don't have triangulation on quakes, so much is possible!
OMG I just realised why Spock is a "vulcan" because like a volcano, they are calm and reserved until they eventually explode
Also because his planet, Vulcan, is supposed to be volcanic.
Vulcan was supposed to be a planet in our solar system. en.wikipedia.org/wiki/Vulcan_(hypothetical_planet)
Roman God of fire and black smithing.
If Mars was still watery today, I wonder how much greater the push would be to land a human there.
If it was still watery and active with surface volcanos, there would almost certainly be life that we would have found already 👀
There would also need to be a better atmosphere too
maybe
It's sad that we only have one Earthlike planet in the solar system. Imagine if Venus and Mars had a biosphere like Earth, filled with strange alien plants and animals to discover.
mars is still watery today... its just in solid form as ice accumulated at the poles.
Life likely exists on Mars underground with geothermal energy as the main source of energy instead of photosynthesis so it likely resembles deep underground ocean-like life if it exists at all.
It’s crazy to think the last time a volcano erupted on Mars humans were just forming the beginning of civilization
It’s crazy to think the last time a volcano erupted on Mars humans were already forming the beginning of civilization!
Different expectations ...
It’s too bad Pohl’s Crater wasn’t on one of the poles. Then it could be Pohl’s pole crater.
Yeah, horrible
you look good, Hank! And Martian quakes actually surprised me. not a huge cognitive dissonance, but a wonderful surprise!
I remember when the paper came out because it came out a day making a research paper for my geology class proposing the theory of a mantle plume to explain the seismic activity under insight 😮
Poor Mars. It's little plume shows magma down below but only a little bit, maybe just in a few places. So, we thought it was dead but it is screaming out "I'm alive! I'm alive! Please let me prove it because I don't want to be dead."
Great video❤️❤️❤️
Intergalactic Defibrillator from the center of the galaxy for planets!!! 😮
Go Go Sci Show!
I read this as. "Are marshmallows causing underground lava lakes?"
“Dinosaurs never made it to Mars”…. Deep Time: Hold my beer.
What!? I though for sure I defeated Mars that one time!
Man, mars having some geological activity still goin on makes me so excited for when we start colonizing.
If it is alive then shouldnt that reflect in magnetic activity too?
Mars does have magnetic activity, but its just wayyy too weak to affect things alot
5:20 that's a rather misleading image and caption. That isn't the chicxulub crater. That's the city of Merida. Hank's commentary is far more on point. The impact site is just off shore, very near to that part of a the peninsula but very little of it is actually visible. There are sinkholes in an arc across a portion of the peninsula that denote where the ancient crater rim was but the familiar crater structure doesn't really exist anymore due to weathering.
its not misleading... that is where the crater is. a largely weathered crater but still where it is located.
5:34 "The non-avian dinosaurs, which we don't think were on Mars... but it's possible..." _EXCUSE ME WHAT_ "...that the water the asteroid smashed into-" _Oh._
Don't you forget Io when you talk about active plumes ?
Turns out Martians do exist, they just all moved to their sweet lava lamp core to hang out. Personally, the Martians consider Humanity lame for wanting to live on the non-lava lamp having surface of Mars like a bunch of squares.
Hi Hank!
What if the mega tsunami on Mars was related to the formation of Earth's moon? And possibly subsequently the start of our own known geologic history.
The chicxulub crater pictures is literally just a photo of the town of mérida….
if mars core is cooling. then the quakes could be gases trying to find a weak point in the crust. in order to escape.
Well it still has a little bit of magnetism, so yeah, obviously it has some heat leftover.
Nice quiet area around a mantle plume there could be water, cave systems, wet mud etc. Underground yea but some weird stuff lives in pockets like that on earth.
Bring your fishing net. You know, wherever there's water, fish will be jumping out at any moment!
crab people
@@rubiks6 well... liquid water. mars has lots of water.. its just in ice form.
@@Ddub1083 - Yes, I understand. I was being facetious.
Im fairly certain Spock practiced Martian Vulcanism.
I apologize. I'll go home now.
hawaiis volcanoes arent special because the are in the middle of the ocean, but that theyre in the middle of that tectonic plate. Most island volcanoes are still caused in areas associated with the boundries of tectonic plates. hawaii and some others are special because they are NOT at those boundries.
Mars is just chillin atm. Basically takin a break from the cosmic BS.
There's actually a movie related to this oppy
The Mars rover that "sang" itself Happy Birthday is the _Mars Science Laboratory_-class rover Curiosity, not the _Mars Exploration Rover_-class rover Opportunity, however the latter has been given its due by SciShow.
Do they align with the ring of fire? Do they shift with the earth's magnetic poles? I need more🤔
The conclusions about Mars that are often drawn that we all just accept based on like, one study, never get the same level of scrutiny as research here on earth, say in biology or something.
Cool.
After a long hard day at work, I like to soothe my brow with a steaming hot cup of Linode.
Good morning Mars! Welcome to the show. We'll talk again soon. -Sol
This hurts
Hey Hank, where can i buy those hoodie?
I hadn’t even considered the fact that earthquakes can’t be called earthquakes on Mars. Although, is it correct? The word “earth” (lower case e) refers to the ground and soil etc., not the “Earth” (capital E).
A wet Mars sounds like a cosmically ancient stage in our solar system. But it had water as recent as 3 million years ago? We start seeing humans first appear on the carbon dating timeline around 2 million years ago. That is just a single million years apart between a wet Mars and humans existence. The majority of the history of life on Earth overlaps with a wet Mars longer than it does without.
Mars's not dead; he's surely alive!
He's living on the inside, roaring like a lion?
I didn't know Fredrick Pohl had a crater named after him.
I am glad he said, "tidal wave" at least once.
Mars not dead it’s surely alive, living on the inside quaking like a lion.
Imagine if we ever get to Mars and dug up skeletons of some crazy life forms.
Better mantle plumes than toilet plumes. Close the lid before you flush 🤣
The thought that mars could have once been teeming with life, potentially around the same time earth is an interesting one.
However, it terrifies me. It's possible that both earth and mars went through catastrophic events, but earth got lucky and mars didn't. It's possible that we were not the first life holding planet in the solar system, but we could be the last.
If it's core is still liquid then there is a future chance of re igniting the core again
Quite frankly, if Mars had evolved even microbial sea life, it wouldn’t be hard to come across.
Imagine if we came across an ancient cave system on mars and find any kind of writing on the wall......imagine if it translated to
"3rd planet is our last chance."
I read a very well written scifi fanfic once with a similar premise... left a lump in my throat. "Aurum Orbis" by BoFlicker...
if that situation were true, then wouldnt humans haev had writing ever since they were on earth? they wouldnt have gotten here from mars and forgot how to write.
John is heartbroken
The last decades the amount of water that was there on Mars has grown from "complete dry" to "there's water now", and now we have a literal tsunami.
Hmm... If Mars really still has activity of that sort, then...
Could future colonies use geothermal power?
If only we could give Mars a gravitationally effective moon.
Why isn't this on SciShow Space tho? 🤔
Cause they did a video about star quakes today!!
Don’t we know that Io has volcanic activity too?
Bro ain't that image of the Crater in Mexico the city of Merida Yucatán lmao 😅
Cause the crater is way out in the Gulf if I'm not mistaking... And it's massive, like a 100 miles wide or something
It was NOT a tidalwave! It comes from tidewater, and the moons of Mars would not have made much of a wave... Only if they crashed into a Mars sea, they could make a big wave, and i would still not be a tidalwave.
The Sun also affects the tides, not just the moon. The moon is just Earth's greatest tidal actor
So the asteroid hits with such a force that Martian microbes get ejected off of Mars and make it to Earth thus Jumpstarting life here. I'm sure someone is already working on this. It would be awesome if it was true.
A planet, any planet, will surely have a molten core. How could it not? The core of any planet is under such emense pressure that there should be lava rock and molten metals.
2:03 Isn't "Cerberus" pronounced with a soft c, not hard? So it should be "sir-burr-us"
It's actually more accurate this way to the ancient pronunciation of the word, though not to the modern interpretation
@@awaredeshmukh3202 Is it? I always thought it was the soft c sound :D
In Greek it’s pronounced as a K. In Gaelic too, btw. Celtic is pronounced as Keltic.
@@kellydalstok8900 I know about Celtic, obviously not every C will sound like S, but Cerberus to me always has.
Cool to know that Mars is more alive than previously thought
"Um akshully technically that would be a magma lamp"
Remember don't drink the water !
I understood that reference
I wrote a book in fifth grade that there was a light bulb inside Mars and made it glow. So validating!
Thanks for using my image. However it's not made by rendering. NASA data and Photoshop are my only tools.
The Mars Volta
lol imagine if scientists find demons on mars like in doom
„on the planet next door” - oh, that would be Venus.
so what about the same processes on Earth?
FutureOfHumanity report states we are screwed...
Or maybe it's sand worms. Praise the Great Maker!
it's "dear john and hank"
We now know what killed the Martian dinosaurs!
How very interesting... to find dino fossils on Mars.
2:07 I spy a microscope.
So it sounds like it it weren’t for the collision with what is today the moon, Earth’s core May have cooled enough by now to slow down the dynamo known as our molten core and we would look like mars.
wow
I wonder if geothermal energy would be avaliable on Mars
A science fiction writer. “A” science fiction writer?
Frederick Pohl, one of the most influential of the golden age science fiction writer, please. Couldn’t you at least have said his name to make it easier for curious people to find him?
Mars isn't dead. It just smells funny.
And so how can we wake up this “mellow” planet? Nukes?
They're gonna release the Tarrasque 🤦
Na earth. Mars is fine. They'er not dead
They're just high
So he just chilling
Earth quakes on Mars should be called Mars quakes..
If Mars used to have water, does that mean that Mars also had an atmosphere?
Yes. It got striped away by solar wind after the magnetosphere went.
That Mars rover has more of a life then modern day people
Except that it’s on mars.
Yeah, like people can't do more than the mars rover *I say sarcastically from my walker wishing I could go out and explore the nature around me like that FECKIN rover can on Mars*
When people?
I feel attacked
haha modernity bad
We don’t need to spend money to live on mars, when we can just put time into fixing this one
Imagine if someone clapped after the bot sang itself happy birthday.
I'm a live, hunk of man.
Doesn't Cerberus have a soft "C" and is pronounced "ser-ber-us"?
