I've been there with my best friend who lives 2 hours from there, and its an absolutely gorgeous sight to see !
2 hours is the other side of Ireland
In reality this place is unbelievable. No picture can do justice. It is mind blowing .
The Giants' Causeway appears on the cover of Led Zeppelin's album Houses of the Holy.
I’ve been there a lot of times in fact I don’t even have to get a plan oh I need to do is drive because I’m from Belfast
northern ireland's greatest tourist attraction in my eyes from a local.
"he had a problem with.." I expected him to say alcohol.
When your Irish it’s not a problem, it’s just how everyone lives
Was there last week, found it quite interesting. Also Dunluce Castle and The Dark Hedges not bad :)
i have been there! Ireland was an amazing experience i suggest you go there no matter what
I love Ireland!I was living in Tyrone.
We have in the Philippines too.. waterfall with columns like that..
Where in PH?

This guys voice is so nostalgic.
Let’s think about it. We’ll start by simplifying the problem. Imagine you pour hot lava over a completely flat landscape. Something like Bonneville salt flats. Imagine you had so much lava that if filled the landscape to say 100′.
OK. A few things to note.
Lava is very hot and a fluid. Because it’s a fluid the temperature would be very uniform. If there was a really hot area, heat would flow out of that area until the temperature was uniform. So in any direction along the surface the temperature would be the same. There would be no horizontal “thermal gradient”.
Eventually the lava would solidify into basalt stone. It would still be very hot, but it would no longer flow.
Basalt is a good insulator. If you think about the profile of the basalt, the surface would cool quickly, but below the surface it would stay warm because the deeper you go, the more insulation it is. This means there is a vertical thermal gradient.
OK, so now we have a very hot, very flat chunk of rock of that is cooling. As it cools, from the surface down, each “layer” is also shrinking. Since the surface is cooling fastest it is trying to shrink fastest too. When it shrinks it sets up a stress gradient. This gradient will look just like the thermal gradient. It will be uniform horizontally, but vertically it will change with depth.
When the stress gets high enough the rock will eventually crack. Once it does crack, the cracks will propagate. So now we have two questions:
What will the pattern of the cracks be on the surface?
Once there are crack patterns, how will these propagate?
The second question is easier. The cracks will start at the surface. How deep will they be? Well since there is a thermal gradient (and thus a stress gradient) as the cracks propagate down they eventually stop because the rock below is still hot and hasn’t had time to build up stress. Eventually rock at that depth will cool a bit more until the crack opens up a bit more. Keep at it long enough and you’ll see the crack propagate from the surface, vertically down all the way through the layers, until it’s reached then bottom of the basalt layer.
So now the hard part. We know that whatever pattern the cracks start with will propagate down into columns. But why hexagons? Well, starting a brand new crack is hard. The stresses must be VERY high to do it. I don’t mean to anthropomorphize the cracks, but you can think of it this way. Cracks seek to release as much stress as possible for the smallest possible crack.
So what patter breaks up the surface with the least total distance? This is the problem of “tiling a plane” or “tessellation”. There is some rather complex math to prove it, but it turns out that the shape that tiles a plane with the least edge length is a hexagon. If the cracks “choose” hexagons at the surface they will release the greatest horizontal stress for the least amount of cracking.
So there you go. A perfectly uniform lava flow will crack at the surface to relieve stress. Cracking in a hexagon pattern relives the maximum stress per unit crack. Once started the vertical stress gradients in the lava flow will propagate these hexagonal cracks vertically thus forming the familiar columns.
Although I know nothing about science and stuff, but i think im a bit enlightened by your explanation.
Nerd🤣🤣😂
Thank you!
This is why hexagons are the bestagaons:3
giant petrified plant stem cells...
wow musta been crazy for such an anomaly to happen with stone,its beautiful
I am astonish. Nature creation always beautiful.
i have been here and i crossed the rope bridge it was so cool
Remarkable!
Reminds me of the DragonMalte Trench or World Scar from ark survival evolved
beautiful view. love it...thanks
That was so fun let's do it again!
Houses of the Holy
Anyone?
It is an interesting thing!
You people should come here, I have found hundreds of ancient giant pillars. Pillars height is around 10 to 20 feet. Comment down for more information.
Tell me more
@@adrianmedina3582 according to locals these pillars are made by 'Pandvas' around 3000 B.C. But this place is not so famous and only locals are aware about it.
"The Giant built a bridge to Scotland, but scientists ...are about to ruin everything fun about that fucking story!"
Aye and tell a far more epic one :P
Yes they do
HOLY FUCK THAT CAUSEWAY IS GIANT
haha volcanic event XD
?
4 years later 😂
A video game actually brought me here ...in a meandering way. I began playing Dragon Age Inquisition on Ps4 in 2015 and I remember the hexagonal geological formations looking fascinating. In some areas there were spiders inside the formations - caverns - that led from one area to another , and in other areas of the game were dragons( not inside the caverns, I only found them on the outside Only when watching a t.v show that I stumbled across this. I had no idea this was a place on Earth that inspired the video game.
Giant tree tump
Very interesting. From an Irish guy.
Also in Hidalgo, México he have the Prismas Basálticos... Huasca de Ocampo... cheers
hrprada those formations are big trees of the past...just search and you will find answer
Quarry
Cool story bro, should write a book
Not that I am saying it could not have been done by nature, but why do we not see this in any other part of the world? Only time I have seen shapes like these in nature is crystals. Anyone know what kind of rock that is? Also is there a correlation with crystal formation?
These columns are found in somewhere in the phillpines
Its not far where abouts i live i was there today & its really cool
wow cool i like it
Nice video. I visited the causeway a few weeks ago. Found it very interesting.
Hazel.
its ancient giant trees
Came here to say this👍🏼
Amazing upload
Cool
Is that his petrified water boot 🤔😆
by looking at all their videos im sure they do, unless theres a person that is a huge fan that has most of their viedos...but i doubt that
Respect the giant if ever he is true
The scientist is wrong, the locals are right 🍀 👋
GIANTS DOESN'T KNOW SCIENCE AND SCIENCE DOESN'T KNOW GIANTS.
I wonder how many people seen the door way and didn’t have a camera
hahahaha volcanic? where is the volcano?
@1:36 ayy yo wassup fam
it's an ancient giant tree
it looks like one
correct, if you look the strands of a tree, its hexagonal.. its was a petrified giant tree.. some scientists are stupid..
@@nikolatesla3155 That's one theory. It could also be the hairs and scalp of a giant.
No organic material, no carbon 14 dating, means no tree.
@@nikolatesla3155 Trees are not hexagonal, they're round. No organic material is found in basalt. No organic material, no tree.
These are tendon structures like Devils Tower in USA.
Led Zeppelins Houses of the Holy.
It is so tall
10:39 am xD
lol
Fingal's cave FTW
FT causeway
hexagon is the bestagon
0:27 lol
interesting to tell, thank you
Houses of the Holy
Somebody need to tell that scientist, nature never make things in straight lines or accurate size of structures.
One more hill with pillers exist in a Mumbai suburbs "ANDHERI. ". I studied at a nearby college called ". BHAVANS " COLLEGE. in the year 1962 to 1967. Some greedy builder in need 9f stones started blasting the hill not knowing the uniqueness of the hill. Later on when the truth that became known to the people. the demolition was stopped.
The name of this hill is Gilleburt hill.?????????.
@pudd750 thanks for spoiling the secret, pudd.
I live in Ireland to
*too
Me toooooooooooooooooooooooo
All volcanic evidence does not look like perfect hexagons. Most likely not lava flows. Look more like petrified growth of some kind with hexagonal cell structures.
2 similar places in Vietnam
Hexagons are bestagons

hi
hello
People all over the world eat potatos not just us :) You should too, good for you
expert: this is Vulcanic eruption.... HAHAHAHA
@BirdValiant indeed :P
Dragonstone?
does national geographic really own this channel?
Leave it to the Irish to come up with mythical creatures. First, there was leprechaun, now a mythical giant. Wonder what's coming up next!

Giant's Causeway
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. It is located in County Antrim on the northeast coast of Northern Ireland, about three miles northeast of the town of Bushmills.
wikipedia
why tho
it was a giant petrified tree... do you get it??
year 2021
what? lava does not ever cool into the shape of hexagonal columns.
PickingPaul1 its a rare event D_D
They believe in an evolution event.
All theories and missing links...
PickingPaul1 hexagons are a shape of nature. The earth in parched lakebeds are full of them. Worldwide. Basalt hexagonal columns. Worldwide. Naysayers hate hexagons even more than spheres now 😅😅😅😅😅.
Electric Honeycomb, people. Look it up n get back to me.
You'r welcome.
plant cells are hexagonal, every 4th grader knows this.
Halo infinite
I was looking for this.
Jagog and Magog ???
I went to a Holliday so it was beside the giants hideout place my mom said there is a secret door so I sat beside it to take a picture but I was scared
thanks i learnt alot! xoxoxoxox
Nature doesn't do lines like this, rebel plot.
How can this be a formation, there are no straight lines in nature. It does not make sence.
@AyeYirMa Omg I am so jealous of you!
Who else is watching this for school in 2020
it doesn't take a genius to understand that lava doesn't come out in geometrical shapes lol, earth doesn't vomit in hexagons. this theory is a fruit of wild imagination and even wilder speculation, it's enough to look at world volcanic eruptions now to understand that it doesn't happen in real world volcanic eruptions in modern times anywhere.
0:27vwhat?
❤😊
I find it more likely that giants were involved in its construction than the idea that lava just cooled into hexagonal columns. Come on, scientist, you can do better than that. Why do hexagons form in nature? Is it something to do with the atomic structure of the rock?
The hexagons formed when the rock was compacted die to the lava

Giants did exist, so they're not a myth.
Of course giants are real. Saw them on TV once, they were playing the Colorado Rockies.
@spread0the0disease Cause I love to learn!
Aha obercooles Video
Ireland ****** not NI
@mackawack12346 LOOOOOOOOOOL that's funny XD
u stuck a potato in your dog and bet him, God theres something very wrong with you, id say you get help on a regular basis.. you cant count either hehe
So I'm to believe that a lava flow created thousands of hexagonal columns all identical to each other? No. I don't think thats what happened.
plenty of ways to prove lava could form basalt columns with all the eruptions happening now... it's a really bad theory
Your scientists, the same ones that believe you're a pure chance of nature, will have you believe this is an accidental geological formation. I wonder dumb these scientists can be.
