I've been there with my best friend who lives 2 hours from there, and its an absolutely gorgeous sight to see !

[@BigOlMuffies]

2 hours is the other side of Ireland

[@RandomnessTube.]

northern ireland's greatest tourist attraction in my eyes from a local.

[@verily360]

In reality this place is unbelievable. No picture can do justice. It is mind blowing .

[@marlenagalecka3908]

Was there last week, found it quite interesting. Also Dunluce Castle and The Dark Hedges not bad :)

This guys voice is so nostalgic.

I am astonish. Nature creation always beautiful.

[@alicenaughton4373]

Remarkable!

[@erikk77]

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.

[@JanetFayard]

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.

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?

Of course giants are real. Saw them on TV once, they were playing the Colorado Rockies.

[@michaelharrison222]

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?

[@ronan4521]

The hexagons formed when the rock was compacted die to the lava

[@ivanivanov5530]

To me as a born-into-the-USSR person it was (and still is) a weird, bizarre and outlandish at the same time way of speaking about things, when two reasons, one of them being a scientific explanation and the other - an explicitly stupid bullshit, are both introdused as somehow equally correct. This video about Giant's Causeway is a perfect example of that kind of situation. I mean, Finn MacCool? Seriously?

[@noreply42069]

+Ivan Ivanov it is called culture those kind of tales and stories from the old is what connect and bridge the gap of the next generations of Ireland you know a causeway of culture. I think you should study up on how important culture is to science and the scientific method. different tales and stories provoke an inquisitive mind to be creative and think outside of the box which in turns leads to a more diversified approach at coming up with and solving a problem (science) or problems of the world science fiction almost always becomes science fact. However I am not judging you or anyone solely based on a KZbin comment. I'm sure you understand this subject very well. it was nice sharing points of view with you

[@noreply42069]

+Ivan Ivanov plus those people over there in Ireland are pretty fucking drunk all the time so their stories are going to flood in to every aspect of life. that's science lol when you are drunk you talk a lot and it is usually bullshit so I can see myself being drunk and stoned saying "no way did fucking lava do this. it was that damn giant who can't swim he did this I know it was him. what's his name the cool guy fucking Finn, Finn MacCool....yea man that's him he did this to us thanks Finn fuck science I'm drunk stupid science cant get drunk hahhahahahaha" or something like that.
