Over character limit
No, the last living thing will be my old english teacher. She was in her 90s when she taught me a decade ago and apparently she's still making teenagers miserable into her 100s
Thankfully, Old English is now an elective course.
Grateful to her, she taught me English 50 years ago…strange she was 90 back then also!
Where do you live that they can't find a new English teacher? If she were that good of a teacher she would've trained her replacement by now.
Maybe this is a math problem. If cameras ever come to your village, they'll want to put her on the news.
@@NotSoMuchFranklywhere do you live? Being a teacher isn’t an apprenticeship lol
Based.
“Life, uh, finds a way.”
Bad movie lines will die first.
"Clever girl."
I'm impressed he made it through the whole video without saying it.
I read it as Jeff Goldbloom
“I hate being right all the time.”
There’s something poetic about the first and last bits of life on this planet being the same. Circular.
The conditions will be about the same. Life started in a hellscape and that's where it will end if we are unable to spread it elsewhere.
more like an arch
Yeah... though we forgot a big factor... that life tends to modify it's own environment,
for the environment may shape us, but we'll shape it back,
We're also in this equation btw, we're life too,...
As we are contemplating the future of earth and life... why so passive? Why let that future unfold?, Have you imagined saving the sun and the earth too?
It's not enough to think big when contemplating something this massive, we need to think astronomical
Just by being a kardashev 2 civ we can rejuvenate the sun and possibly extend it's days to the blackhole era,
Heres one of the megastructure/process that can achieve this:
Star mining powered by a dyson swarm, Mine the "poison" of helium, and reseed the sun with hydrogen
Or use a stellar engine like the one proposed in a paper: Caplan thrusters, it'll extend sun's life and move us out of dangerous supernovae killzones
Regarding cycles:
There is a concept where at "max" karma we can escape the cycle (for example reincarnation cycle from Budha) , and we will be cycle breakers,
For we can either die at the end of all cycles or transcend... basically
We can either befriend everything including the universe, or kill all of it
By now, A weapon to pierce the heavens can be proposed, to use ontological concepts themself to forge a future where true utopia is possible
As such I wanna atleast live till when death is not irreversible
You're welcome to challenge such ideas and dreams, To know more is to always see other's perspective afterall
Have a fulfilling day... :3
We as humans go on a very similar arch too, from being a helpless baby to a helpless old person.
It's the ciiiiiiiiiircle of liiiiiiiiiiiiife...
Funny that Ginkos were mentioned as hardy species, when they are certainly individually robust but their native habitat for a long time was elusive and even considered extinct in the wild, until a few small populations were found. Human cultivation over a thousand years ago may have saved this incredibly unique species from extinction, which is a nice tale in the face of our current proclivity to causing extinctions!
And every other species of ginkgo is extinct due to being outcompeted by flowering plants.
@@dweebteambuilderjones7627 It might be the slow change of genom that gives them so much robustness. But this ofcourse means that they are slow to adapt to changes.
A very large Ginko has stood at the corner of my towns High School for many decades. The fruit of the tree smells like vomit and often ends up getting tossed into groups of the student body, Lol.
i didnt understand a thing you just said my guy
@@KarkatrealThen your education system failed you, and I hope that you’ll be able to learn what it couldn’t teach you.
I love the question marks on the leaf even though ginko is so distinct 😁
It did make me chuckle
WHAT COULD IT BE???
"WHOS THAT POKEMON"
"PIKACHU!?!"
"its Ginko!!!"
"F@#K"
@@dorkchops 😂 you beat me to it. G'job.
That head of hair brings me so much joy. Looking amazing and healthy Hank.
I'm bald :(
@@bawlzack7877 I am balding and I am 25
@@bawlzack7877 but is it due to a medical condition? Hank had some pretty severe medical issues lately, so I think the OP is referring to the fact that it's an indication he's through the worst of it.
@@JD-ub5icYeah basically
I have seen a lot of peoples' hair come back curly after chemo baldness. It's really cute!
Evolution: come on gingkos try something new? Gingkos: Nah I think we good, we're basically done with evolving everything we need
Oh, but they do: in extreme situations they fall back on very, very old information stored in their genes: had one "tree-top" that grew in a whole new tree in the last decades, but in the beginning it developed cone-shaped leafs - the pointy bit at the stem. Normal leafs fan out more or even get this divider in the middle of the leaf (Like a Time Lord Collar)
Ginkgo trees are my favorites! Knew what the video topic was just from the leaf shape!
Same!
Me too
What's the most expensive tree in Japan? A Ginkgo tree!
(This joke only makes sense to people who understand English and Japanese.)
Me too, the most beautiful leaf in my book, especially when turned yellow.
The "fruit"... not so much...
Imagining that last little bacteria dying on this planet kinda sad. It's like a final whisper of life in a saga that spanned billions of years
I choose to believe we will find a way off this rock by then.
It'll put the chairs back on the tables for us and lock up the planet behind it when it goes
@@captain_context9991maybe we wont if we stupidly halt all our progress as a species in the name of reducing carbon emissions. We need to get off the planet and established elsewhere before we voluntarily send ourselves back to the stone age
Yeh sounds soo ...........empty and lonely
@@itsv1p3r if we destabilize our climate there won't be much of us to get off of the planet.
I will never stop obsessing over Hank's new curly hair IT LOOKS SO GOOD!
Idk why he reminded me of blues clues this video lol
@@novaenricarter705maybe the striped shirt?
It’s called chemo curls! I don’t know the specifics but it comes from chemotherapy
Yep it's chemo curls! My dad had similar after he had chemo. Also came in much darker. He was a redhead but suddenly he had black hair like his own father did before him.
@@AroundTheBlockAgain Thanks for adding! Correct me if I’m wrong but it goes back to normal after a while of growing, right? -I also didn’t know that the hair could grow back darker but I suppose that makes sense!
Watching your recovery from cancer treatment is amazing. You are an inspiration, my friend.
Preppers everywhere were geeking out when he talked nuclear war then disappointed when microbes took their place on top
You mean I gotta use alcohol for CLEANING
I wasn't geeking out, I was too busy being angry that we are still stuck on this planet, because of the stupid & wicked people among us, and in positions of authority.
We should be living across the solar system by now, and be so advanced, that aging & cancers are cured, and we live forever, but instead we are still collected on this rock, able to be whipped out by any massive thing.
On top of us being held back & sabatoged by all these degenerate people.
I hate so many people.
Yeah but he never mentioned what COLOR those microbes would be(!)
Life finds a way...well, until it doesn't.
Life has a billion years to find a way to another rock to live on. We are likely that way.
@@filonin2 I'm on team 'just make the sun smaller and filter out its fusion byproducts', myself. It requires less advanced technology to do it, it's more sustainable, and it means we get to keep all our infrastructure and historical sites, as well as preserve the Earth's entire biosphere. It'll also make the sun outlive every natural star in the universe, if we do it right.
Life finds a way until the sun gives out. Whoops.
I don't think that's how easy to get rid life out in this universe. The things that life could achieve in extreme circumstances that nobody expect, we might be a parasite in living in a rock because how efficient life itself adapt and evolve. Making us successful flourishing in a harsh unforgiving cold universe. Thinking about it makes me feel special and grateful, at the same time, knowing life true potential for greatness.@@calebdonaldson8770
@@falleithani5411but how would we get the technology or resources to do that
sad not to see fungus mentioned, they were some of the first to make it to the Earth's surface and one of them feeds of nuclear waste in Chernobyl
Yeah, but they feed on dead Organic cells. The last archeobacteria cells would feed on every molecules and sunlight to sintethyze them into organic. so they would outcompete fungus because they would also feed on dead cells molecules from the same bacteria species even... :(
I am so happy you mentioned my favorite tree. Ginkgo trees are just an amazing tree. They can live longer than redwoods. Ginkgo trees are also dioecious. Male ginkgo trees are preferred by arborists because they make great shade and they do not produce ginkgo fruit. Ginkgo fruit smells rancid and like vomit. Furthermore, ginkgo fruit can cause skin irritation and the fruit part can be toxic in high doses. However, inside the fruit there is a nut that is supposedly good. The nuts of the ginkgo fruit are low protein and have a lot of medical benefits associated with them. Ginkgo trees also can survive some of the harshest souls and its leaves turn a golden yellow in the fall. All in all, ginkgo trees are amazing. It is interesting to think that this tree is older than the dinosaurs.
I have a female ginkgo down the street from me with a male next to her and her fruit stunk. The male was cut down to make way for a house so no more ginkgo fruit. The fruit smelled like rotting meat.
Ginkgos are one of my favorite trees ❤
Then there's Smooth Scouring Rush, a reed type plant which has also been around since the dinosaurs and hasn't evolved a bit because it hasn't had to. It's got survival figured out - much to the annoyance of many gardens who don't want it in their gardens....
woah!! scouring rushes (we call them horsetail plants) have been one of my favourite plants for a very very long time, but i had no idea they were that old! going to go hop in a little rabbit hole about them later :D
@@aequinoctiale th-cam.com/video/pYvqjj6a3WI/w-d-xo.htmlsi=a0GtPk_D_ecOlza5 😊
Is that the equisetum? I just rooted a bunch for fun. Very cool plant. Gotta give it up for the bryophytes, too. Hell, all of kingdom plantae is amazing.
@@noeditbookreviews yes! That's the one. There are two that grow in my area, horsetail which has lateral branching and smooth scouring rush that's just the straight stalk with a spore head at the end. They are fun to dig, especially in soft soil when you can just follow a root forever!
'Dinosaur grass' is what we used to call it ..
I am so glad to see this presenter healthy and enthusiastic again. Makes my heart smile.
Was he sick?
@@DaLlamiyes, cancer.
@@DaLlami he had cancer.
Not only did he have cancer, he kept giving updates and making videos during treatment. He and his brother are treasures, no matter the people who were complaining about him telling people he had cancer.

OH. WOW hearing about the patreon. I'm a very broke college student, but this stuff is important and should be shared and continued. I will certainly donate.
It will get better
Just stay away from debt
It's almost the end of summer for me. Time to pluck the Ginkgo leaves and soak them in alcoholic tincture.
PS: Surprised not to see the Tardigrades in this video!
I thought tardigrades would get a mention as well.
I forgot about Tardigrades. I doubt they'd survive the sun going red giant unless they managed to take on AEs or make their way outward. I hope the waterbears make it. (imagines a galaxy-wide group mind of tardigrades "it's warm, come this way")
Never thought to see if Ginkgo leaves were any good medicinally. My oldest walking stick (25 years old, still unfinished with the original end split from improper curing) is a Ginkgo staff coppice from the edge of our middle and highschool fields from old ornamental spread.
The only real drawback is that its ridiculously light and catches terminal velocity like a whiffle ball bat 😂.
Exactly my thought, those are some of the toughest critters on the planet ;?)
Tardigrades aren't extremophiles. They can tolerate extreme conditions through various methods, but they can't live in them permanently.
💛A ginkgo tree decked in its golden foliage is a thing of beauty! I wonder if they should be planted more in reforestation projects?
I planted a Ginkgo tree in my yard. Two years later, despite all my care it died.
My mother referred to it as a Black Thumb. Other things I planted in that yard are thriving, but the little tree never came back.
Looking really good buddy! I'm glad you're doing better 👍🏻

Good to see you back and looking healthy Hank, we missed you!
Wow!! Thanks for the episode guys 😊
Great to see you again Hank!
One video idea I’d be curious to see discussed, especially since I personally don’t know too much about it and how factual it is, is the archeological site in Zambia that has petrified logs with cut marks that were notched together at close to a right angle with a suggested date of 476,000 years old, bringing up the question of if it was made by our ancient relatives, a different species, or our relatives but earlier than we thought
I have a dumb question….couldn’t it be that the MATERIAL is that old, but it was found by some ancestor 100K or 50K years ago and they made something with it?
They were cut before being -petrified- _buried_
Where did you get this information from? I want to look into it
@@MawdyDev TH-cam doesn’t allow links in the comments, so just do a search for: zambia petrified wood cut. A bunch of articles will come up.
@@MawdyDev I heard it mentioned in a Simon Whistler video but it was very brief, then the TH-cam overlords hacked into my brain enough that I was then recommended a more In depth video on it. Look up KSAT 12 they have a video on it from 5 months ago called “Archaeological site from 476,000 years ago ..ect” or something close to that. It was worth the watch
Taxes will survive
Unless communism wins.
And your boss will still be calling you to make sure you’re coming into work on that day!
Mr. Hank Green, I am really happy that you are better now. It's really nice listening to your voice teach me stuff I would die from boredom learning in school.
I remember hearing a science teacher in middle school talk about super novas and the "kill zone" and it legit stuck with me forever as a legitimate fear. That one freaks me out, just boom, little to no warning, everything gone.
I almost never watch YT videos in their entirety. This one had me glued to the end, so to speak. Very compelling!
Ritalin
Try Veritasium, any Tom Scott video, Steve Mold, there are a lot of amazing creators that you can hardly help but watch every minute of their videos. Veritasium's "what IS electricity?" video series led to literally 100+ other great TH-camr's, big and small, all discussing the topic, it was a good time to be in science YT.
What a cheerful episode!
Almost as cheerful as a kurzgesagt video.
@@molybdaen11yes yes

looking good Hank!!!
Glad to see my fave tree getting some thumbnail time. Hope mine gets a good growth season in this year (god, did i just say that? man i’m old)
Can't wait for the next one. I'm excited.
Recently read the book The Ends of the World by Peter Brannen. It's an excellent book all about mass extinction events
Also, there are some paleontologists who think that the "Asteroid that killed the dinosaurs" is actually the "asteroid that triggered massive volcanic activity that, in conjunction with the asteroid, killed the dinosaurs (at least, the non-avian ones)
I heard that too, that the mezeroif alone was not enough but was followed by vulcanic eruptions, with the usual mass extinction after that.
Try the Bobiverse books. They are excellent.
It's not just _some_ paleontologists: Everyone familiar with the fossil records of that period, can see that the impact was not an insta-kill. The extinction event was on the order of 100,000 years long
tbh, "killed the dinosaurs" is a bit of an overstatement as the avian ones survived pretty well, more like the asteroid that forced dinosaurs to go smol
@@diablo.the.cheater Yeah... Actually, even that is a bit of a mislead, because the big ones mostly just died. The ones that survived were _already_ smaller than the "terrible lizards" of the Cretaceous etc
One of the coolest things about Ginkgo is that it still has flagellate pollen, like sperm (ok, not really the pollen- but I can't think of any 'higher plant' who's gamete swims down a tube). Like many other Gymnosperms, the 'gestation' period is long.
The hair is coming along great.. eagerly awaiting the 1st cut and new hairstyle 😊
Love you Hank hope all is well!
Hank: "Something, maybe a burst of Volcanic activity..."
Other creators I've heard talk about it: "Imagine Russia just...exploded."
My botany professor was totally turgid for ginkgo trees. Specifically the leaf vein pattern and the smell of the female tree's fruits.
"Turgid" might not be the right word to use there...
This was wonderfully written.
OMG ! Great work; thanks.
This episode gives me strong Kurzgesagt vibes and I like it
Only thing missing were the birds.
Wow Hank's curls are approaching Peter Pan levels of boyish curls.

Informative content.
Lookin good, Hank
Welcome back hank we missed u!!!!!!🎉
What a cool video! Thank you
dude your hair is looking fabulous
@Hank, my personal theory on what killed the dinosaurs is suffocation. Large creatures need more oxygen and when the levels dropped due to the sun be blocked, all the large animals suffocated.
Dinosaurs had the same type of extremely efficient breathing mechanism (with lung tissue extending into their hollow bones), where the air flows most of the way in a single direction. This would have allowed them to survive in somewhat more anoxic conditions than many large mammals.
While 0₂ levels certainly would have dropped in the immediate aftermath of the vast heat blast from the asteroid's impact, the subsequent firestorms from burning forests sucking up loads of oxygen & the few years of dust clouds blocking sunlight to kill off green plants, I doubt it would have dropped much below 16% of atmospheric volume (it's 23% now). There just wasn't enough time to do much more damage before plants began to recover at an astonishing rate.
I suspect that the Extinction of the Non-Avian Dinosaurs was probably due to a complex combination of those forcing factors we've considered (eg: the heat & shockwave of the impact, disruption of food webs, environmental temperature change, ocean acidification, etc.) & more that have never occurred to us - though it certainly wasn't as instantaneous as we once thought, with some smaller species surviving for a few million years after the K-T Boundary.
@@_ninthRing_ I'm not saying I'm right about suffocation, but your response contains a bunch of assumptions that could be wildly incorrect. In 2013 Science Daily reported that oxygen levels 220m years ago were 10 and 15 percent. That one fact could unravel your entire argument. Do birds need to breath through their bones at sea level? Probably not, but it's required for altitudes where oxygen is lower. If dinosaurs needed their bones to breath at sea level, then that would suggest they were already vulnerable to suffocation.
10,000 years will give you quite the magnificent light show
easy come, easy go, friends. we're all just travelers visiting on a short lease visa to have a glimpse. we came from eternity and we shall return
I need to stop getting existential crises from these videos and focus on the ones where Hank talks about chemicals that go off if you make dirty looks at them
It's soooo good to see you hair back dude!
It never occured to me how poetic the end would be. Thanks for that!
Of course if that supernova in a kill zone did happen today, we wouldn't find out about until up to 160 years from now.
But we can tell if a star is close to supernova, so we'd probably have a little heads up.
there _would_ be established precursors that would give us an ETA of a Super. There are certain signatures that are light emitted when the stellar object is gobbling down the last bit of consumable fuel before the big old gravity event transpires.
Or if it happened then 159 years and 355 days ago it will happen here tomorrow. Everyone is aware of light speed limitations.
I doubt anyone will be left to "choke" over a million years of depleted oxygen. Those that rely on it, will be gone then.
Why would they be gone?
Because they would have choked on a lack of oxygen.
This video really puts things into perspective like PERSPECTIVE
Hank! Great hair! Thanks for everything you do.

Hank!!! Missed seeing you on SciShow!!!!🥰🥰🥰
Ginkgos are cool. We have the Ginkgo Petrified Forest National Park here in WA. It's where the very 1st specimen of Ginko petrified wood was discovered, even though it only represents around 1% of the material found at the location. It's also part of why petrified wood is the state gem.
I was very saddened when the unfortunate demise of Lemmy Kilmister (lead singer with the incredible Motörhead for the uninitiated) burst my youthful bubble, as he and cockroaches were certain to outlive us. But the knowledge that some of the extremophiles that I’m studying could help us mere humans prepare better for the inevitable is a small consolation. RIP Lemmy.
I'm not sure about the last living thing, but I'm pretty sure the last intelligent thing will be something rather like a human checking that all the microplastic has been cleaned up before returning to its family aboard a far more efficient and long-lasting habitat than a mere planet.
A habitat that lasts more than billions of years? Ok, lol.
Childish idea
@@filonin2Give it a couple tens of thousands of years before you write it off.
Congratulations on beating cancer brother glad to see your hair back
SciShow should do an episode on how toxic or inhospitable Earth would be to alien life.
Letz see:
High levels of toxic oxygen which destroys DNA and even let metals rust.
Agressive microbes everywhere.
Vulcanic eruptions, earthquakes and weak magnetic field.
Low level of free available amoniak.
High concentration of salt.
Annoying natives.
He seams to be enjoying telling us about this just a little too much .
Im proud of you Hank, greetings from Iceland
