David Gallo: The deep oceans: a ribbon of life

[kerron68]

I always wonder why organisations, such as NASA, spend billions on outer space explorations, when we've only looked at such a small percentage of our own planet. Shouldn't we first understand our own life forms before looking for others?

[Chronobeanz]

10:28 looks like there's someone stuck in the chimney.

[russelbourbaki]

2.4 km >240kg/cm2

[Pootsman666]

absolutely fascinating.

[fiendin281]

that fish is the emperor of the vents

[dmlled]

amazing

[swyft187]

Would love to hear a follow-up on research of these two, considering that this video is 10 years old!

[swyft187]

S-p-e-c-t-a-c-u-l-a-r-!

[tehLeecherer]

leet vid

[VideoFlights]

Really interesting stuff, and despite usual trash we regularly see, it's good to see that there are still lots of good videos on Youtube - well done

[arnoldesnumerouno]

yeah i agree completely,

cheers to whoever is putting these up i really appreciate it

[roidroid]

6:26, is he actually suggesting that there is bacteria living IN the molten rock of the Earth's mantle?

[invisiblethreat]

I have made four mildly interesting videos, but you are welcome to see them, enjoy.

[penguinworm]

I just don't understand how these fragile looking things aren't crushed from the pressure. What's different about their basic makeup?

[nevous8]

Can anyone tell me how these creatures aren't crushed under pressure?

[guitarguy93]

Adaptation, evolution. They probably can't live in the pressure we are used to.

[nevous8]

we are talking about hundreds to thousands of pounds of pressure though... how can a crab just withstand that... maybe i'm getting the definition of pressure wrong when you're that far deep as the scientists said that they just disintegrate when they travel towards water to land level?

[IslandHermit]

Their internals (blood, membranes, etc) are at that same pressure, so the internal and external pressures balance out.

That's why they disintegrate when we try to bring them up. The external pressure drops well below the pressure inside their bodies, so they basically explode.

[ColinFrayn]

They don't have gas inside their bodies like we do (our lungs and other air-filled cavities). They're basically just bags of liquid and solid chemicals. Liquids are not generally very compressible so the pressure doesn't affect them.

[Fragenzeichenplatte]

you should bear in mind that we as land animals are living under a large pressure, too - the pressure of the atmosphere around us. I just read that the human body has to endure 5.5 tons of air!

[kurtilein3]

why do they keep using those old, outdated, non-scientific units like miles, feet, and fahrenheit? and even pounds per square inch...

almost the whole planet uses the metrical system now, including most scientists in the united states, and the united states are one of the very few nations that continues to use the outdated, complicated, illogical imperial system. stop it. just adapt to the metrical system.

[SpoolDonkey]

metric is just so much more easy and precise, it is posible to convert, i think its divide by 24.5 or multyply by the same amount, but so much better when its all based on multiples of 10.

[MeLikeGoFast]

No.

[horseluvrxox]

@kurtilein3 Take a deep breath. It will happen in due time! (already did...) but typing angry words on youtube-of all sites-won't change a single thing. If you want/need something to happen, get out from in front of your computer and make it happen. :)

[crudhousefull]

@horseluvrxox At least he/she voiced it. That's part of making the change. You don't have to go killing people to make change. I'm guessing you're American

[horseluvrxox]

@crudhousefull You're the one who brought up killing people...

We Canadians believe in making a change, and not just talking about it. So you think all Americans are gun slinging-freedom wanting rednecks? I'm guessing you're-I had something written, but then I realized that they might come and kill me.

Oh well. You're not worth fighting with. Case rested.

[Yesios]

@kurtilein3 To get their own civilization confused. It's the same with the month/day/year system...

[semiliteratedgod]

nice pictures but really nothing new, you're a fucking retard or you live in a cave or something if you didn't hear about this earlier

[ChaChinnngK]

"STFU fucking retard, go kill yourself worthless scum"

Woo, you're original.

I'd advise you to go elsewhere to direct your mushbrain-droppings, preferably towards someone who cares what a dull character like you has to say, and let the others watch their videos in peace.

shoo !

[Darkstepper219]

and i'll fuck yer mouth too.

[fiendin281]

you're a horribly annoying person

shoo!

[Darkstepper219]

please stay in contact with me on here so we can meet and i can pump your mouth with hot sperm.

*kisses*

[DABUdabuDABUdabuDABU]

ted is the only quality thing on the internet. period.

[akulol]

very interesting to watch!

[maurieer]

Simply an awesome video!

5/5

[CheeezMaster]

and yet we dumped 12 million + tonnes of plastic in it.

[LothairApoclyane]

somebody had to do it

[Mrmoc7]

Haha

[CheeezMaster]

lolz

[indagdnm]

I LOVE TED TALKS!!!
