The Blue Hole in the Ocean is So Scary I Can’t Sleep
1. 
I wonder where the bottom is.
2. There are holes even in the ocean, huh…
5. That first one is way too scary.
6. Now I’m scared.
16. Is the first picture a different hole to the other two?
19. >>16 If you look at the scale it should be obvious.
24. >>19 I wanted to know if one could appear simply by chance, or if certain conditions have to be met first.
18. What on earth is this? Tell me more.
29. >>18 If it’s the one in the Bering Sea, apparently it’s a hole where methane hydrate blew out in the past. It’s dozens of metres in diameter and hundreds of metres below the seabed where lava touched the methane pool and caused it to explode.
The average global temperature rose by 10 degrees Celsius when it erupted.
33. >>29 Amazing!
22. 
I want to jump into it!
26. >>22 It looks like someone threw a ball into the ground and that’s what remains.
28. >>26 It’s called Crater Lake, apparently long ago a meteorite hit there.

It’s like this.
27. 
30. >>27 You beat me to it.
34. They haven’t explored it with a submarine yet?
37. >>34 It’s not even deep enough to be the deep sea, I don’t think there would be much there.
35. Wasn’t there a video on YouTube where they went into a hole?
48. >>35 This one?
49. >>48 That’s terrifying!
50. >>48 That’s brighter than I expected. It’s still dark, but it’s brighter than a moonlit night or something.
54. >>48 He doesn’t have an oxygen cylinder!
38. The deepest hole is only 202 metres, it’s barely anything.
39. If I have a quick peep, I might see a Leviathan-type monster looking back at me, right?
40. 
Scary.
43. >>40 No thanks.
46. >>40 Are there any dams in Japan that have a hole like this?
41. Aren’t reservoirs and bell-mouth spillways terrifying?
44. I’m scared of bell-mouth spillways. Makes me think that after it sucks me in, it’ll spit me back out so I violently hit the ground.
45. It’s similar to trypophobia, so some people have a phobia of bell-mouth spillways too.
51. There was a video of someone investigating a blue hole who then disappeared, right? That’s scary.
52. 
I know this is fake, but it still scares me.
53. I seriously think there are as many mysteries in the ocean as there are in space.
