Ignorance was bliss, wasn't it?

I think you should stop now, you are wasting your own time. It is completely flawed because colour within any species is too varied and governed by too many endogenous and exogenous variables. Add the variables of equipment and techniques, it becomes a futile and meaningless exercise.

If you imagine a sphere with layers like an onion, the mass - and hence local gravity - of each layer, starting from the outer layer, diminishes to nothing in the middle.

My apologies, it's 554. I've bookmarked the Guardian's Counted site and been looking at it nearly everyday, trying to make sense of the data. This centralised compilation of data is what the US government should be doing. Reading the notes to each case, I'm definitely getting a feeling cops are quite often reaching for their guns much too quickly and quite a few people are getting shot in the back running away... it seems that this is sufficient reason to use a gun on someone: when they bolt.

People killed by police up to now 555. 123 of them unarmed.

Cheers for that. Yes, that is very plausible and the japanese scenario is just as energetic and chaotic with obstructions and holes in the path. Put some crosswind in the mix to blow the spouts sideways it looks very possible. The lack of resolution and sensitivity in the video would smooth/blur the spouts to look ghostly.

If a person is a flat-earther and they're an adult then changing their mind will be akin to changing a leopard's spots.

Yeah, this feels a bit like an aging fan asking his hero for an autograph for his teenage son because he's too embarrassed to say it's for himself.

Not heard that one before. Could be a possibility.

It's because it is digitally zoomed in by a large degree.

I think the OP is trying to find an effort-free solution to obesity.

Nope, I was fishing in the Humber Estuary a couple of years ago, which has a major cargo port in it and I could clearly see the effect as the ships came to and fro', sight unaided, just like the video I posted.

Yes, I don't think normal camera lenses are flat-field by default. Cheaper wide-angle lenses will give pronounced curvilinear effects. How do you know that's not an artifact of your visual system?

A carbon dioxide fire extinguisher could do the job of dry ice couldn't it? I discounted the lens/atmospheric aberration idea because the plumes get blocked by the trees in a way consistent with something going behind them; any aberrations would be superimposed on top of the image.

Obesity, for most I think, is down to a sedentary lifestyle and motorised transport. A case in point, although only a single data point, is that I''ve always been 10 stones. I was very active and my main modes of transport were walking and biking. From last November, for one reason and another, I'm pretty much a couch potato. My diet has not changed and yet I am now 12 stone 4lb. I've gone from being at the bottom of the BMI range to just over it in six months. a good stone of it is around my waist.

This illustrates that some people can only believe what they can see and primitive commonsense governs the rest.

A gas plume can rise that high and last if it's big enough to start with.

You can see the over-the-horizon effect here: https://www.youtube.com/watch?feature=player_detailpage&v=dV0h68YU0iQ The bridge I mentioned is the Humber Bridge.

There is a single span bridge in the east of England that has two 155m towers 4626ft apart. Many years ago I happened to be working in a field some miles away that was in the middle of the two towers and I could clearly see the towers leaning outwards when it was pointed out to me by the chap I was with. It's quite a sight. I can't find any pictures on the internet from that position. The simplest logical proof is that, looking out on the ocean horizon, you will always see the top of a tall ship first before you see the hull as it into comes into sight or is the last thing you see as it goes away into the distance, like it's coming or going over a hill. If it was flat the ship would just get smaller and smaller until it was a dot. Edit: X-posted with swansont

Could it be a ruptured pressurised container and releasing discrete plumes of a liquified gas as it rolls in the water? It will condense whitish as it is released.before dispersing. Fire extinguisher?

Yes, that's gong back to the estimated beginning of Homo sapiens, a million or two years. The number is incomprehensibly large at that point, so there's little point going back any further.

You are in the moment. I'm in lizard-mode, it's 33oC and nearly 6pm..

Yes, no point worrying about what you don't know... it wastes the present.

Yes, like life is a journey not a destination.
