SciShow - 2020-04-09
Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all life began. Hosted by: Michael Aranda SciShow has a spinoff podcast! It's called SciShow Tangents.

I love watching Michael Aranda. I miss his blonde streak. The science was awesome too.
I've noticed he's doing less of these videos! Come back man, you're a great presenter!!
I agree 100%!
We got plenty of olivine here in Hawaii. One of our beaches is “green” from all the olivine in the lava rocks. ImuaTMT
Excellent delivery. Great voice and actually conveying info rather than reading. Great stuff.
Indiana Jones: The Lost City and the Origin of Life
Methane is also a fuel that releases much less carbon dioxide than other hydrocarbons. This is because it has the lowest Carbon:Hydrogen ratio possible without being completely hydrogen.
lol blow it out ur ass!!!!
🐿💨💨💨👈🐿😂
White smokers, sounds like my school
A school of; Crack commando's?
Four twenty!
This was so cool. I love how things like the story of Atlantis keep influencing things in science. It shows how connected disciples can be.
Thank you! I have been trying to tell people that there is one case where water does go above 100C without turning to steam.
I love the ocean so much, i can't wait to explore it when this DAMN pandemic is over!
Just watched the cosmos episode on this topic! really neat!
Did they explain why it's called "Lost City" and I missed it? The science is fascinating but I kept wondering about the name.
Yes. This thing is in the Atlantis massif, which is in the Atlantic Ocean. That made somebody think of The Lost City of Atlantis. There you have it.
The process built tall underwater towers out of bicarbonate and so on.
@ 0:50
@jmchez "That made somebody think of The Lost City of Atlantis."
I wonder how many people upon hearing what the scientists call the feature use it as evidence of ancient civilizations. I'm guessing it's not zero.
The thumbnail asks, "What is a white smoker?" My immediate thought, 'the beginning of a bad joke."
Holy crap, it pours out hydrocarbons?
We could everything from that, that would be an excellent place fire life to evolve.
Delicious electron gradients!
"delicious electron gradients"
I tried them 1/10 would not recommend.
White smokers let everyone know when a new Pope has been elected.....how soon we forget.
I had an uncle kinda albino lookin’. He was known in the neighborhood as the white smoker.
And he means it. Point. Blank. Peridot.
I'll see my way out.
Keep your day job, if you still have it. :)
Lost City? Just equip a Dramen Staff, and enter the shack in the swamp. Duuh.
Zenyl the hard part is getting the staff.
Michael, where did you find your Birds Aren't Real shirt? I really like that one.
birdsarentreal.com and Amazon have them!
"what is a white smoker?" my dad
Great content! Would be great to see a follow up video on geologist Mike Russel's work on predicting the existence of white smokers before their discovery
Could the serpentinization reaction be a potential “renewable” source of methane (natural gas)?
Not renewable since it involves degrading rock, but in theory you cold pump CO2 into rock beds and have it produce methane for consumption.
It can be a non-renewable source of methane that needs raw peridot for fuel and CO2
Ngl, some parts of this made me want to burst out a vessel over hoe complicated it sounds. Its still a lot fun tho lol.
Seems like it would be relatively easy to find possible life on Io, the place is like one gigantic Yellowstone Park. It's got hot places, cold places, warm places, all sorts of organic chemistry in liquid.
Agreed! I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
If Europa or Encleadus have Hydrothermal vents life would be all but confirmed there.
@Neburay Why is that?
@Gordon Chin Europa and Enceladus have been proven to have Liquid Water oceans. If they have white smokers life could emerge there
great video ! a little feedback though : maybe ease out on sentences ( visually ) while describing complex chemical reactions - narration in the back ground and wordy sentences on screen at the same time makes it a tad difficult to follow the science
Did you realize you posted this comment at least three times?
@Luin Tathren I did not .. some glitch with my network . Thanks though
I learned about black smokers from SeaQuest DSV beck when I was a teen. Loved that show.
Are there any brown smokers under ocean? Few people like me feel left out by these representations.🤣
hydrothermal vents: I can be your angle... or yuor devil
Lost City of Atlantis Massif. Yes, a totally random name, haha.
Awesome as ever and thanks for always being there! ❤️
Atlantis? Lost City? Man this could almost have been an April Fools video! 🤪🤣☮️❤️🌈
Man, this one wins the "Most Complex SciShow Episode" award, I had to watch this four times to wrap my mind around it.
"Dang it, Jim! I'm a doctor, not a geo-bio-astro-chemist!"
Did you find out why they published this video now? The science they present is from 10-20 years ago, or did I miss something?
Thanks ... I get to a point where Michael goes (again) but that's not the most interesting part .. and I think - wait, what?
@Eljan Rimsa I didn't read it 20 years ago, so I'm very happy they published it now. Truth be told, this is a 'history' primer, so everything I read about it from now on will have a good grounding. facepalm
@Eljan Rimsa: This isn't a news channel. This series is even called "Weird Places".
I remember to have wathed one of the recent episodes of Cosmos in which they mention that olivine is one element necesary for the origin of life, this video confirms this affirmation.
All of the rare conditions needed to create early life makes me think that 1 planetary body per galaxy birthing life is overly optimistic by a few factors of 10.
Which makes me more scared of death and at the same time more appreciative of what time I have.
The fact that he proposed three moons as places where life could exist, when multiple star systems have been proven to contain planets in habitable regions, but those moons are outside the "habitable" zone, tells me our definition of "habitable" needs some serious consideration.
This video tells me life may be more common than you think.
@WaterspoutsOfTheDeep your first sentence indicates you did not watch this video.
@WaterspoutsOfTheDeep you made a public comment. asserting that nature didn't give rise to life. i'm going to refute that. whats more, our right to speak also gives us the right to disagree. i see more evidence that life arose naturally than evidence that life arose supernaturally. this video offers more proof of a naturalistic origin to life.
@WaterspoutsOfTheDeep there is no difference between macro and micro evolution. they are the same thing. we have OBSERVED speciation events. look up e.coli citrate evolution.
http://www.evo-ed.com/Pages/Ecoli/index.html
"The nutrient broth .... contains a large amount of citrate, which is included to help the bacteria take up the iron they need to grow. This citrate could be a second food source for the bacteria, but one of the defining characteristics of E. coli as a species is its inability to grow on citrate when oxygen is present. However, after ~31,000 bacterial generations, one of the populations evolved the capacity to do just that. The evolution of this trait, called Cit+, is exceptionally rare. Indeed, spontaneous evolution of a Cit+ E. coli was reported only once in the entire 20th century!"
this is evolution. this is proof that it happens.
but this video is more focused on abiogenesis, an entirely different field of study from evolution. as different from evolution as cosmology is from evolution.
but if you are a science denying young earth creationist, you will have recieved the brainwashing misinformation that everything you dont accept is just a different "kind" of evolution. and that by attacking only evolution, you can somehow disprove ALL science.
but you STILL wont have proven god.
Atlantis? Well SpongeBob discovered that city before humanity
I'm do happy that i am alive sci show is the best
I knew about these because of a project in a programming class I made in eighth grade (2010)
so wait, are these structures made out of a mixture of serpentinite (-/+ magnezite) or just calcium carbonate?
white smokers
Well of course I know him, it's me!!
Black smokers you say? well, that would be me and my Newports!
insert clever Left4Dead reference here
@Jo Luffman Ok Boomer
Nyan Kitty witch, please.
Serpentisation, olivine. Did you get the idea of this episode from cosmos possible worlds?
q. what is a white smoker?
a. my older brother
Great ep!
I'm surprised we haven't recreated life in a lab yet.
I haven’t found any research indicating they have. Any source would be great. This is interesting news.
PrettyBitchForever!! Ya but it’s not recreating life. They just used cells that were already there and try to control it.
I'm sure somebody has become pregnant in a lab;)
@M.C Mole Look at https://en.wikipedia.org/wiki/Miller%E2%80%93Urey_experiment to find the follow-up experiments.
A broader overview explaining different theories and the reasons why it's so difficult would be https://en.wikipedia.org/wiki/Abiogenesis
An advanced cutting-edge research example is https://en.wikipedia.org/wiki/Planet_Simulator
Afaics we are able to plausibly create first organic building blocks, but we are still a long way away from experimentally creating RNA or DNA.
@Yurtfan1987 funny bugger ;-)
Given the state of our humanity life on earth must have begun when an advanced alien civilization dumped their septic waste on a then barren planet.
1:39 I thought olivine contained magnemites and steelix. 2:19 it does form magnetite and iron and steel is mostly iron! I deserve a mineral badge!
You're not getting that badge unless you bet Brock like everyone else!
5:17 Europa and Enceladus' pictures are wrong. They're switched
managed to get capture attention,good video btw,please make more of this
When life first appeared on earth ultramafic rocks rich in olivine were much more common than today, which corroborates the hypothesis
I’m like Michael’s voice. He’s my favorite SciShow host.
wow. lots to process. i'm gonna have to watch this again to get a grip on all of that science that just got dumped :)
The way he says peridot.
Thats my birth stone and just don't sound right there's a DOT at the end 😂😂
Interesting new pronunciation
Walk into a jewelry store. Point at something with a lime yellow greenish stone and ask what it is called. 95% of the time the jeweler will say "Pear ee doh"
Go to Phoenix, drive an hour east to the town and ancient volcano that has a lot of it and ask "What's the name of this town again?" and the locals will say "Pear ih dot".
